UNITED STATES WILLIAM SAVINI, or omesso,

TRUCK HOIST.

Application led July 3, 1926. Serial No. 120,504.

This invention relates to improvements in hoists particularly for use with railway-car trucks or the like, and has for one of its principal objects the provision of such a hoist which can be eectively and readily operated, thereby saving a great deal of time and labor.

One of the important objects of this invention is to provide any hoist or grappling means especially adapted for application to railway material and equipment, particularly trucks, which by its operation will effectively and conveniently act in the transferring of such trucks from one point to another. Still another and further important object of this invention is the provision in a grappling moet of a plurality of elements associated into a single operating unit comprising a minimum of parts and therefore inexpensive to manufacture and one which eliminates the necessity of repairs.

Other and further important objects of this invention will be disclosed in the accompanying drawings and following specification.

The invention in a preferred form is illustrated in the drawings and hereinafter more fully described.

In the drawings:

Figure 1 is a perspective view of the improved grappling hoist of this invention showing the same in raised position.

Figure 2 is a sectional view taken along the y line 2-2 of Figure 1.

Figure 3 is a detailed view partly in section taken along the line indicated at 3-3 in Figure 1.

As shown in the drawings:

The reference numeral 10 indicates generally the body member or main supporting element of the improved grappling hoist of this invention. The same preferably comprising a unitary solid block of metal as illustrated and having a series of four notches 12 formed in the ends thereof for the reception of the Divoted ends of grappling arms, hooks or the like 14.

These grappling arms or hooks 14 are pivotally mounted on shafts 16, passing transversely through suitable alined openings in the ends of the block 10 as best shown in Figure 2, and the arms themselves are mounted on suitable bearing sleeves 18, whereby an ease of operation is assured. l

Formed integral with the block 10 and at approximately the center thereof is an upstanding ring element 20 as that shown ini4 55 Figure 1 provided for the reception of a chain ring or the like 22, which in turn'is adapted to receive the end of a supporting hook 24, which is mounted on an elevating pulley 26, the same being operated by a chain 28.

Outstanding arms 30 are also formed integrally with the base memberlO and at the end of each arm is a pair of pulleys 32 through which passes a grappling hook operating cable 34 as best shown in Figure 3. It willf` "65 be obvious that the supporting ring 20 and the extending arms 30 may be formed separate from the body 10 if so desired, and may be bolted, riveted, welded or otherwise secured thereto. f A

The operation of this device will be obvious, as it is to be suspended by the chain 28 from a traveling crane, or the like, and lowered into position above a truck or similar object which it is desired to move. The oper-75 ating cable 34 is then released, allowing the hooks 14 to drop into position underneath the axles or other parts of the truck, after which the whole may be securely lifted and safely transferred to any desired position.

I am aware that many changes may be made and numerous details of construction varied throughout a wide range without departing from the principlesof this invention, and I therefore do not purpose limiting the patent granted hereon otherwise than as necessitated by the prior art.

I claim as my invention:

A hoist including a body comprising a unitary block of metal in the shape of a rectan-NO gular parallelepipedon, a grappling hook pivotally mounted in v'aligned slots in each side of the body, a pivot pin passing through each aligned slot to support the grappling hooks, a transverse member positioned at substantially-D the outer ends of the hooks for reinforcing the said outer ends of the saine and means for operating said grappling hooks from a source of remote control, said means comprising a cable attached at one end to the transverselOO 2 'l f j 1,727,942

reinforcing member'of each hook and with its other end adapted to be manually controlled, supporting and guide means for the Cable, said means comprising arms extending 5 upwardly lrnd outwardly from the body and above the line of action of said hooks7 together with pulleys mounted in the endsof the arms for cableoperation? In testimony whereof I affix my signature.
