SCHLE NKER BOLTLESS ANGLE BAR FOR RAILROAD RAILS 2 Sheets-Sheet 2 Filed May 12. 1928 cfL. ,S chZ en ATTORNEY Patented Oct. 8, 1929 UNITED STATES PATENT OFFICE JACOB L. SGHLENKER, OF KTJ'LM, NORTH DAKOTA BOLTLESS ANGLE BAR Application filed May 12,

The object of this invention is to provide rail securing means which will not require the use of bolts, and which can be applied and when desired may be released in a simple and direct manner.

A further object is to provide, in a device of this character, an element for engaging one side of the rail or rails, and carrying pins for the bolt holes of the rails, this device including a base and a lateral extension, and a second rail-engaging member adapted to cooperate with the extension in the special manner disclosed below.

A further object is to provide one of the elements with a toothed extension, and the other element with an offset tongue for en-, gagement with the teeth.

A further object is to provide cooperating rail engaging elements to be manipulated by a special tool, in securing the rail, or the rail ends,or in the releasing operation.

lVith the foregoing and other objects in view, the invention consists in the novel construction and arrangement of elements described, illustrated and claimed, it being understood that modifications may be made within the scope of the claims without departing -from the spirit of the invention.

In the drawings,

Figure 1 shows the device in elevation, as connected with abutting rail ends;

Figure 2 is a top plan View;

Figure 3 is an elevation from the other side, as compared with Figure 1;

Figure 4 is a section on line 4-4 of Figure 1;

Figure 5 is a section on line 55 of Figure 1;

Figure 6 is a similar section, with the special tool in position;

Figure 7 shows the device being released by the tool;

Figures 8-and 9 show the elements of the rail securing means in perspective, each View illustrating one member of the clamp;

Figure 10 is a perspective view of the tool, with the handle portion broken away.

The abutting rail ends are designated 10 and 11, and the rail-engaging members of the clamping elements are shown at 12 and 13,

FOR RAILROAD RAILS 1928. Serial No. 277,252.

each of these portions last named having an upper outwardly turned flange such as that shown at 12. Member 12 carries pins 141 for engaging the bolt holes of the rails, and devices l2 and 13 are bowed to provide resilient engagement with the web portions of the rails.

The portions 15 rest on the base of the rail or rails, and clamping element 12 with its portion 15 has formed therewith a base portion 16 extending under the base of the rail, and between short tongues or ears 17 having holes for rail spikes therein.

Extension 13 is turned upwardly and includes an upwardly extending tongue formed with flanged engaging devices and constituting a toothed channel member or U member and the web of the channel has an aperture 19 for engagement by swinging hook 20 depending from handle or lever portion 21 of the tool of Figure 10 and elsewhere.

Clamping member 13 of Figure 9 includes apertured ears 17 for the spikes, and between the ears an upwardly and outwardly extending tongue is provided and includes portions 22 and 23, the latter having apertures 23 for the reduced ends of pins 24 forming the legs of a swinging staple member or U member 25 mounted in the lever 21 and spaced from the hook 20.

The tool is applied as in Figure 6 when securing the rail ends, pressure on the handle of the lever 21, extending to the left of the rail, tending to produce downward movement on tongue 23 and upward movement on the hook 20, so that a clamping action is effected between the end of tongue 23 and the toothed portion 18' on the other clamping element.

In the releasing operation, the reduced end 28 01. the tool is applied as in Figure 7, and downward pressure forces tongue 23 from the toothed portion 18, thus separating the elements of the clamp.

that I claim is 1. In a device of the class described, a clamping element including a side portion, a base portion to be positioned under a rail, an d an upwardly extending portion, a second clamping element including a side portion and an upwardly extending portion, and locking devices automatically engaging under pressure and carried by said upwardly extending portions for effecting connection therebetween.

2. In a device or" the class described, a clamping element including a side portion, a base portion to be positioned under the rail, and an upwardly extending resilient tongue, a second clamping element including aside portion and an upwardly extending tongue for engagement by the resilient tongue when placed. under pressure, the tongue of the second clamping element including engaging means.

3. In a device of the class described, a clamping element including a side portion, spike engaging means, a base nortion, and an upvardly extending tongue l'OlZHGCl v. th means, a second clniping' element ineluding a side portion and an upwardly extending resilient tongue for cooperation with the tongue first named when the resilient tongue is placed under pressure for effecting loclzii'ig enge geinent.

4. In a device of the class described, a plurality of clamping; elements each including a tongue and the tongues extending; from the same side of a rail when the clamping elements engage the rail, one of ti e tongues including notched and channeled end portion, and the other tongue including guiding; and engaging portions for coo eration Will the channeled end.

In. testimony whereof I aiiiX my signature.
