SPIKE-HOLDING DEVICE.

'Applicaton'ned'December 24, 1924.` Serial No.757;824.

T0 all whom, t may concer/ri:

Beit known that I, RUSSELL H. illuminer, a citizen of `the United States, and a 'resident of Easton, county ot NorthamptoinState of Pennsylvania, have invented a certain Spike-Holding Device, of which the `following is a specification accompanied by drawings.

This invention relates to improvements in railroad spiking devices, but more particularly to a device for holding and guiding the spike while it is being driven into the tie.

The present invention is especially adaptedto be used in conjunction with a pneumatic spike driver or other similar tools.

One object of the invention isto enable the spike tobeheld and guided by mechanical means during the initial driving of the spike.

' Another object is to separate the spike supporting members automaticallyafter the initial driving of the spike to permit the driving element and the head of the spike to .pass therebetween.

Further objects will appear hereinafter.-

In the drawings forming part of this speciieation, Y

Figure l is a side elevation of a spike holding device showing the normal position of the parts,

Figure 2 is a view similar to Figure lY showing the holding members separated by the end of a pneumatic spike driver,

Figure 3 is an end elevation of the device, and

Figure 4 is a top plan view.

Referring to the drawings, the spike holder comprises a saddle member A having a baseB, a depending Hange- C on one side, and depending guide plates D on the opposite side. In this instance the base B is adapted to lie directly on the top surface of a rail E. Suitable lugs F are arranged to Contact with one side of the rail, and with the flange C form a guide-way for sliding the device along the head ofthe rail, and vto prevent transverse movement of the device.

The guide plates D are preferablyzformed with an angular base G to register with the edge of the rail flange and to be supportedon the top face of the flange, thereby holding the device in operative position.

Means are provided for holding and guiding a spike I-I until it has penetrated the .tie H to a suitable depth when mechanical guidance is no longer required. To this end, a pairoi' arms J having recessed jaws K at one end are mounted on transverse pivots L, and are provided with `lateral lugs C) to cooperate with the top ot the base-B Ator limiting the movement of the arms `in one direction. A Y 4 i The jaws K are preferably held in clamp-r ing postion byplungers l? and coil springs Q, which act `upon one side of the arms to Jforce the jaws Vtoward a. common central position. Grip members R are arranged near the ends of the base B, thus providing convenient means for. transferring the device from one position to another.

In this instance the forward portion of a pneumatic spike driver SV is shown in operative position on the head of the spike. H.

In operation, the device is arranged upon the rail directly over the tie. The spike is then inserted between the jaws K, and the driver S is applied to the head of the spike. As the spikepenetrates the tie, the front end of the driver will act upon or against the top surface oit' the aws K thereby causing the jaws to rock simultaneously abo-ut` thel pivots L and permit the forward end of the driver S to pass therebetween.

Upon removal ot' the driver, the jaws will be returned automatically to their normal position by the plungers P and the spring Q. The device may then be placed in position to drive a spike on the opposite side of the rail, as indicated by the broken lines in Figure 3, or may be moved slida-bly along the rail to the next tie.

Although the invention is described as having'only a single pair of jaws, it is to be understood that a similar pa-ir. may be arranged on the opposite side of thedevice. In this manner spikes may be driven into the tie on the opposite sides of the rail without requiring a change in the position of the device.

I claim:

l. In a spike holding device, a saddle member having a base, a -depending flange, depending guide plates, arms mounted p1votally on the saddle having jaws to hold a spike, and means for holding the jaws in a normally closed position.

2. VIn a spike holding device, a saddle member having a base, a depending Harige, depending guide plates, pivota-lly mounted arms with jaws `for supporting a` spike perpendioularlj7 to ay working tace, and means for holding the jaws yieldingly against the spike. v

In a, spike holding device, a saddle member having a base, a` depending flange, a` pair of depending guide plates, pivotally mounted arms having jaws at one end to support and guide a` spike and lugs at another end to limit the movement of the arms in one direction, and resilient mea-ns for' holding the jaws yieldingly against the spike.

'111 a spike holding` device, a saddle in'e'mber having a base,'a depending flange, depending guide plates, a pair of arms having recessed aws at one end and lateral lugs atanother end and secured pivotally to the saddle to slidably support a spike perpendicularly to a working face, and spring pressed plungers to force the jaws against the spike. j

5. In a spike holding device, a saddle comprising a base, a depending lange to cooperate with a. side of the rail and a pair of depending guide plates to cooperate with a rail-lange 'for support-ing the device in an operative position upon the rail, a pair ot' arnis mounted pivotally to one face ot the saddle, said arms having recessed jaws at one end to receive and guide a spike and lugs at another end to limit the movement of the arms in one direction, and spring pressed plungers eo-aeting against the arms to return the jaws to a normally closed position.

In testimony whereof I have signed this specification.

RUSSELL H. VLHELM.
