TEMPORARY TIE-HOLDING DEVICE.

Specification of Letters Patent.

Patented Mar. 18, 1913.

Application filed June 11, 1912. Serial No. 703,031.

To all whom it may concern Be it known that we, HOMER A. WITZIG and Jones A. FnnMoN, both citizens of the United States, and residents of Leeper, in the county of Wayne and State of Missouri, have invented a new and Improved Temporary Tie-Holding Device, of which the following is a full, clear, and exact description.

The invention relates to devices that are used for lifting and holding the tie against the base flange of a track rail while the holding spikes are inserted, and has reference more particularly to that class which comprises a lever formed of two parts flexibly connected, to fulcrum on the head of the rail, and means associated with the lever to engage the tie and the head of the rail.

An object of the invention is to provide an inexpensive and eflicient device possessing suflicient resiliency to withstand the shocks while the spikes are being driven into the tie.

Another object of the invention is to provide a device with which the tie may be brought against the base plate of the rail in a perfectly vertical direction, and held there automatically until attached to the rail.

The invention consists in the construction tie is raised and held firmly against the base plate of the same ready for spiking; Fig. 3 is a plan view of Fig. 2; Fig. 4 is an elevation of the gripping clamp for automatically holding thedevice during spiking and Fig.-

5 is a modified form of a tie-gripping member of our invention.

Before proceeding to a more detailed clescription of our invention, it must be understood that the prongs engaging the under side of the tie may be of any suitable shape, and the end of the lever forming the prongs may be simple or bifurcated, as disclosed herein. The device as shown by the drawing includes a lever of the first class, pivotistering holes 5 is provided in each prong,

to permit a variation in leverage, by transposing the bolt 6 and the roller 7 loosely mounted on the bolt and disposed between the prongs of the lever. WVhen fitted in one of the sets of holes 5, the bolt 6, in connection with the roller 7, forms the fulcrum for the lever 3 and the entire device. In the upper end of the lever 3 and at its extremity an orifice 8 is provided to admit a bolt 9 with ample play in same. The part of the bolt 9 projecting above the lever 3 carries a coiled spring 10 bearing at one end on the lever 3 and at the other against the washer 11 in contact with the nut 12 screwed on the bolt 9. The part of the bolt 9 projecting below the lever 3 is pivotally attached to the second-class lever 13 by means of a pivot 14 attached near the fulcrum 15 of the lever 13. At the free end of the lever 13 a clamp 16, having the end of the lever 13 as a pivot for its handles 17, 17, is suspended, the jaws 19 of the clamp being pivotally joined at 20 and connected to handles 19 by pivots 21, 21, as best shown in Fig. 4.

In the modified form of our device, the only change is in the lever 3, where the lower end engaging the under side of the tie, is formed of a single prong 4, and to prevent the fulcrum point of the lever 3 slipping off the head of the rail when the device is applied, a large flange 22 is made to project below the head of the rail on the opposite side of the lever 3, the flange 22 being mounted on the bolt 6 forming the fulcrum for the lever, and provided with a roller 7 When a tie is to be fixed to a track rail, the device is placed in position, as indicated in Fig. 1, the prong of the lever 3 engaging the under side of the tie 2, and the lever fulcruming on the head of the rail, the coiled spring 10 maintaining the lever 13 against the lever 3. A downwardforce is then applied on the end of the lever 13, thus compressing the coiled spring 10, and in consequence forcing the tie 2 against the base of the rail on the line of least resistance, that is, vertically, as the fulcrum point of the lever, being the roller, will roll on the head of the rail easier than the tie will displace the ballast on its sides. The effort of the lever 13 is continued until the jaws l9 are made to engage, by means of the handles 17 of the clamp 16, the under side of the head of the rail 2, and maintained so by the coiled spring 10 tending to intensify the grip of the jaws on the rail, as shown in Figs. 2 and 3. After this is obtained, the spikes may be attached, and the device is disengaged first from the head of the rail by applying a downward effort and forcing the handles 17 of the clamp 16 apart and relieving the pressure. Then the) prongs of the device may be disengaged from the under side of the tie, thus completing a cycle of operation.

It will be readily understood that the spring 10 forms a resilient support for the tie, and in consequence of this the device is not injured by the shocks produced during the fixing of the tie to the rail.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

1. A device of the class described, comprising two flexibly-connected levers, one of said levers having means for holding a tie against the rail, the other of said levers having means for attaching to the rail to hold tie in position.

2. A device of the class described, com prising a lever of the first class, a lever of the second class pivotally connected intermediate the fulcrum and free end of said first-class lever, and a resilient member connecting the two said levers and limiting their relative movement.

3. A device of the class described, comprising a lever for use in connection with a rail, a fulcrum on said lever adapted to rol.l on the rail, and means on the ends of said lever to engage a tie and to hold the same against the rail.

4. A device of the class described, comprising a lever of the first class, means on one end of said lever for engaging a tie, a lever of the second class, means at the free end of said second lever to attach to a rail, and a flexible member connecting said lovers.

5. In a device of the class described, a first-classlever, a second-class lever, a pivotal connection between said levers, the pivot constituting a fulcrum for said secondclass lever, a rod pivotally connected to said second-class lever and extending to said first-class lever, a coiled spring on said rod and in engagement with said first-class lever to maintain the two said levers normally one close to the other.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
