RAIL-HANDLING DEVICE.

Specification of Letters Patent.

Patented May 9, 1911.

To all whom it may concern:

Be it known that I, BLYTHE HARPER, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Rail-Handling Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in rail handling devices.

The object of my invention is to provide a device of this character which permits of the handling of rails separately and collectively and in a convenient and expeditious manner for loading or unloading for transportation.

Another object of my invention is to provide a simple, cheap and effective device of this character in which rails of any length can be readily handled.

In the accompanying drawings; Figure 1 is a side elevation of my im roved rail handling device in operation. *ig. 2 is an end elevation of the same, showing the yoke in a vertical position, and showing the device as applied to the rails when handling them collectively. Fig. 3 is a side elevation of one of the rail grabs. Fig. 4 is a bottom plan view of Fig. 3. Fig. 5 is an end elevation of the yoke, and Fig. 6 is a detail view of the shaft retaining means.

In its general organization, this rail handling device comprises two sets of hooks or grabs which are adapted to engage opposite ends of the batch of rails to be lifted, two yokes, each of which pivotally carries a set of grabs, and a tackle whereby the two yokes are connected operatively with each other and also with the crane or hoisting device as is common in such practice, whereby the grabs and the load carried thereby are transported from one place to another.

It is evident that one or more rails may be handled at a time with this device as desired,

but in the drawings the rails are shown as arranged in the form of two horizontal rows resting one within the other forthe purpose of economizing space, the rails of the lower row being arranged with their bases lowermost and side by side, and the rails of the upper row are inverted and arranged with their heads between the webs of the lower row and their bases resting upon the heads The batch of rails in this nested condition is shifted without interruption from one place to another as previously indicated.

Referring now to the drawings, 1 represents the yoke in which the grabs 2 are pivotally mounted upon the shaft 3 which is carried in the lowermost portion thereof. This yoke is preferably made of sheet metal and completely surrounds the shaft 3, its two halves being brought close together and holding between their upper edges the suspending rods 4, of which there are referably three, their upper ends being united by a suitable clevis 5, for engagement with the hoisting cable. Openings .6 are formed through the hub portion of the yoke 1 in which the grabs are mounted. These openings are made somewhat wider than the length of the hubs of the grabs so that shimming washers 7 may be mounted upon the shafts 3 between the ends of the grab hubs and the inner walls of the openings, thus providing an adjustment of the rabs longitudinally the shaft 3 to provide or diflerent sized rails as the washers may be interchanged, the openings 6 being of slightly different sizes.

A rectangular shaped block 8 is interposed between the hubs of the central grabs and held between the sides of the yoke by means of the pin 9, this block 8 having a projecting teat 10, which engages the annular groove 11 within the shaft 3, whereby the shaft is securely held longitudinally, thus avoiding any nuts or cotters upon the shaft 3, which might obstruct the operation of the device.

Each of the grabs 2 is formed with a bifurcated or forked bill, the prongs 2 of which are adapted to straddle the web of the rail at one end thereof and bear against the under side of the head of the rail when lifted, the upper edges of the prongs being suitably shaped for this purpose.

The two sets of grabs having been properly placed upon the opposite ends of the lower row of rails of the batch to be lifted and also connected with the hoisting and shifting device by means of a tackle which preferably comprises a main cable 12 connected at one end with the hoisting and shifting mechanism and at its other end to the clevis 5 embracing the yoke supporting rods 4: and a pulley block 13, which receives the main cable and is connected by means of a short cable 14 to the clevis 5 in the set of grabs in the opposite end of the batch of rails to be lifted.

In attaching the handling device to a batch of rails, that set of grabs connected to the pulley block 13 are first engaged with one end of the batch of rails and then the set ofgrabs which are connected directly to the main cable 12 are engaged with the opposite end of the batch of rails. Upon now drawing or pulling upon the main cable 12 the two sets of grabs will be first drawn tightly into engagement with the opposite ends of the batch of rails and after being thus tightened, the further or continued pull of the main cable will cause the load to be moved either horizontally or vertically, depending upon the direction of pull of the main cable, this being governed according to what it is desired to do with the load. After the load has been shifted to the desired place, the main cable is slackened sufficiently to permit disengagement of the two sets of grabs from the ends of the batch of rails and the grabs are carried away for another load. In order to prevent the set of grabs that are directly attached to the main cable from being hauled close to the pulley block 13 when no load is being carried and the grabs are being drawn back into position for another load, a stop 15 is securely bolted to the main cable a short distance from the block 13 and between it and the set of grabs. This stop may be of any desired shape, but is sufiiciently large so that upon striking the pulley block, the same can notpass, through it, thereby holding the grabs of the main cable at a considerable distance from the pulley block and permitting the engagement of the same with the ends of the batch of rails without any inconvenience and unnecessary loss of time in drawing the cable through the block.

While I have shown the preferred means of carrying my invention into practice, I do not wish to limit myself to the exact construction shown, as the same may be varied in many respects and still come within the scope of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
