Trolley Dollies

It’s a lovely day out, and you decide to go for a walk along the trolley tracks that crisscross your town. As you walk, you hear a trolley behind you, and you step away from the tracks. But as the trolley gets closer, you hear the sounds of panic — the five people on board are shouting for help. The trolley’s brakes have gone out, and it’s gathering speed. You find that you just happen to be standing next to a side track that veers into a sand pit, potentially providing safety for the trolley’s five passengers.

All you have to do is pull a hand lever to switch the tracks, and you’ll save the five people.

This invention relates to a stop and feeder mechanism for use in a trolley conveyor and to a means for operating said mechanism, and more particularly to a proposition of storing load trolleys in such a manner that, when one load trolley is stopped, other trolleys coming in succession are stopped and retained in due order at fixed places for a fixed period of time. There have been heretofore many propositions for the method of stopping and feeding trolleys by engaging a pusher with dogs or releasing the former from the latter, said pusher being attached to a drive chain which is continuously driven parallelly above the load trolleys and said dogs being provided to said load trolleys.

For instance, one structure comprises fitting a rotatable cross arm in a horizontal slot formed in the pusher frame of the drive chain so as to be rotatable longitudinally of the horizontal slot, and disposing a push spring between the retainer of said cross arm and said pusher. In the structure, when external force by man or machine from the direction opposite to that in which a load trolley travels is given to the cross arm that works on the dogs of the load trolley from the side of the load trolley, the cross arm is retracted Within the slot of the pusher arm against the force of said push spring and is released from a stopper separately provided on the pusher arm, thereby to release the cross arm from the dogs of the load trolley.

The method described has a disadvantage that separate external force must be imparted to the trolley or the load thereof which it is intended to stop and that the force must be held continuous and unless otherwise said trolley or load is carried away by the pusher of the chain driven around in succession. Furthermore, said method is attended with the trouble to have to provide all the pushers of the chain with the structure described. Another known structure is a device generally termed an indexer in which a chain trolley is caused to escape above a load trolley thereby to release the load trolley from the chain trolley and retain same.

This type of device also makes it necessary to provide each of the chain trolleys with a special release member or a movable rail portion for raising the selected portion of the chain track and power means for moving the movable rail portion. Accordingly, te user feels inconvenienced in that the stop and feeder stations of load trolleys cannot be readily altered. A primary object of the invention is to provide a novel means of an indexer by which one load trolley and other load trolleys coming in succession are released in due order from the pushers of the drive chain at selected stations along a conveyor line in a trolley conveyor and the load trolleys are retained in safe while the spaces between the conveyed workpieces are maintained as desired.

Another object of the invention is to provide a stop and fee-d mechanism, by which not only one load trolley can be stopped but other load trolleys coming in succession are automatically brought to a halt in due order by stopping one foremost load trolley, in a structure which has mechanical versatility. A further object of the invention is to make it possible to provide certain desired stations along the conveyor line with as many stop and feeder sections as required not by providing each of chain pushers or load trolleys with complicated mechanism but merely by adding a simple unit to the required sections of the load track.

The characteristic aspects of the invention which achieve the described objects will become apparent from the following detailed description of one preferred embodiment of the invention made with reference to the accompanying drawings in which:. Referring now to the drawings, a drive chain 1 is suspended on a chain track 2 by chain trolleys 3 and is moved to the right side in the drawings.

This invention relates to trolley current collectors and, more specifically, to an improved current collector for use at high speeds. Current collectors for vehicles powered from overhead wires have evolved over many years with various improvements to overcome problems involving ease of use, maintenance of electrical contact between the current collecting shoe and the overhead conductor and handling of the stresses imposed on the system under various operating conditions.

As the speed requirements of the electrically powered vehicle increase, vibration and noise problems have become more severe, and the devices which were useful under operating circumstances of some years ago are no longer satisfactory. An important factor is the fundamental condition that the electrical conductor is not rigid. Rather, it is a wire, or a set of wires, which can flex and move within certain limits.

Although the wire is braced and restrained in various ways, it can nevertheless oscillate and undergo complex sets of vibrations and other movements. Thus, although there have been many prior efforts at vibration solutions including springs and other mechanical devices, they have not been entirely satisfactory. Some are too complex and expensive some are simply too difficult to maintain in order to be practical in the field. Examples can be found in the following documents.

Self-driving cars hold out the promise of being safer than manually driven cars. Collisions are sometimes unavoidable. So self-driving cars need to be programmed for how they should respond to scenarios where collisions are highly likely or unavoidable. The accident-scenarios self-driving cars might face have recently been likened to the key examples and dilemmas associated with the trolley problem. In this article, we critically examine this tempting analogy.

We identify three important ways in which the ethics of accident-algorithms for self-driving cars and the philosophy of the trolley problem differ from each other. These concern: i the basic decision-making situation faced by those who decide how self-driving cars should be programmed to deal with accidents; ii moral and legal responsibility; and iii decision-making in the face of risks and uncertainty.

In discussing these three areas of disanalogy, we isolate and identify a number of basic issues and complexities that arise within the ethics of the programming of self-driving cars.

For floor-operated cranes, the controller or controllers if rope operated, shall automatically return to the “off” position when released by the operator. Pushbuttons in pendant stations shall return to the “off” position when pressure is released by the crane operator. Inspection procedure for cranes in regular service is divided into two general classifications based upon the intervals at which inspection should be performed.

The intervals in turn are dependent upon the nature of the critical components of the crane and the degree of their exposure to wear, deterioration, or malfunction. The two general classifications are herein designated as “frequent” and “periodic” with respective intervals between inspections as defined below:. At the beginning of each operator’s shift, the upper limit switch of each hoist shall be tried out under no load.

This invention is for a material handling crane of the type usually identified as a “hammerhead” crane. It is commonly, but by no means exclusively, used for transferring bulk material from a barge or ship to shore, or vice versa. As generally constructed, it has a structural steel tower with opposed horizontal arms or structural cantilevers projecting therefrom, one of which may extend from the dock out over a ship or barge anchored alongside the crane. The other cantilever may then extend landward to a storage pile, train of cars, conveyor or perhaps over a receiving barge or ship in a slip at the other side of the dock.

The crane, therefore, is roughly the shape of a letter “T” and, with its vertical column and the diagonal braces for the cantilevers, its contour resembles that of a hammer, from which the name “hammerhead” is derived. The lower part of the tower may include a turntable to enable the upper part of the tower with its cantilever arms to be turned about the vertical axis of the tower, or in the parlance of the industry, to be “slewed.

At selected positions the gantry may be releasably clamped against movement. The rails provide a track to allow the crane to travel along a dock or such other places as the crane may be used. This is not critical, except that the drawings, being on such a small scale, convey little impression of the magnitude of the forces tending to topple the tower if a severe condition of unbalance should arise.

Various schemes have been devised for counteracting or compensating for the changing conditions of imbalance and unequal stress conditions which are encountered with each cycle of operation of the load trolley and its bucket or other load raising, transporting and unloading means. We are aware that some attempts toward equalizing the stresses are used and are satisfactory with relatively small unloading cranes, but which for various reasons, one of which is the great length of cables for racking the trolley and the hazards of breaking under certain conditions, would result in unsafe or dangerous movement of both the load trolley and the counterweight to the same end of one of the two opposed cantilevers, with possible injury to workers.

According to the present invention, there are upper and lower horizontal trolley tracks extending from a limit or terminal near the outer end of one cantilever to a limit or terminal near the outer end of the other cantilever. There is a counterweight movable horizontally along the upper track.
