RAIL JOINT AND CHAIR.

Specification of Letters Patent.

Patented n t. 23, I915.

Application filed May 25,1914. Serial No. 840,792.

Clinton, in the county of D ewitt and State of Illinois, have invented certain new and useful Improvements "in Rail Joints and Chairs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and i tron, aline with the openings 0. When in use the same.-

My invention relates to improvements in railway chairs and joints and has for its object to provide a simple, efficient and-inexpensive device of this'character which will obviate the necessity of employing bolts,

nuts, and nut locks for uniting the meeting ends of the rails.

To the above end, I employ a rectangular base block, rail bracing plates carried there by, said plates acting also to prevent the removal of a number of fastening pins to be described.

A secondary object of the invention is to provide simple and eliicient means for securely locking said bracing plates in position.

With the above and other minorobjects in view, the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein:

Figure l is a top plan view of the invention showing the manner of its application; F ig. 2 is a side view of the parts shown in Fig.1; Fig. 3 is a verticalsection through one of the rails, showing an end elevation of the joint; Fig. & is a vertical transverse section on the line H of Fig. 1; Fig. 5 is a perspective view of one of the bracing plates; Fig. 6 is a similar view In the accompanying drawings, I have shown the meeting ends of two rails R, the webs of said rails being provided with the usual transverse openings 0. Disposed between the flanges. F of said rails and the cross ties T is my improved chair and coupling.

The invention comprises a base block 1 which extends longitudinally of the rails R and is preferably rectangular at its base, its

opposite ends 2 rising vertically, while its of one of the. memberaemployed for retaining said plates in position; and Fig. 7 is a perspective View of the entire base block.

longitudinal side walls 8 incline upwardly and 1nwardly. The block 1 is provided, at the JIiIlCtLll'G of the inclined walls 3, with an Inverted T shaped slot 4 which opens through its upper .sFIle, said slot being provided for the reception of the flanges F of the rails R and for the lowermost portions of the webs IV thereof, the upper edges of said walls being-provided with transverse notches 5which, when the rails are in posiorder to cause their ends to lie flush with the inclined walls 3.

For the purpose of inore'rigidly bracing .the rails It and for retaining the pins 6 in position, I provide a pair of longitudinal bracingplates 8 which, are substantially wedge-shaped in cross section and having their upper edges held in forcible contact with the under sides of the heads H of the rails R by means of longitudinal ribs 9, the latter being cast integrally with the side walls 3 and having their inner iadges undercut as shown at 10, said under-cut portions co acting with the-narrow lower edges of said bracing plates.

"On the inside of the track, the bracing plate 8 is preferably held in proper position by means of a pair ofspikes 11 which pass through notches ,12' in the lower edge of said clamping plate and are driven through shown in Fig. l, the ribs 9 terminate a slight distancefrom the ends of said block 1- for 1 allowing the proper application of the spikes 11 on the inside of the track and for allowing ample space for the provision of other fastening means which are employed on theoutside of the track. Said last mentioned means comprises inclined plates 13 which are suitably shaped, on their under sides for contact throughout their length with the inclined walls 3 and the outer faces of the bracing plates 8, the inner edges of said plates contacting with the ends of the ribs 9, while the outer edges thereof are provided with upright plates 14: which extend laterally therefrom and contact with the ends of ably secured in this position oy spikes 15 which pass through alined openings in said lates and the base block 1 and enter certain of the ties T.

on it becomes necessary to remove the rails, the spikes 11 and 15 are removed, whereupon the plates- 13 and the bracing plates 8 may be readily removed, thereby allowing said rails tobe pulled endwise out of the slots 4, after the pins 6 have been removed.

From the foregoing description, taken in connection with the accompanying drawthan those amplified in the appendedclaims'. Having thusdescribed my invention, what claim as new and desire to secure by Lettors-Patent is: I r

,1. The combination with the meeting ends -of a pair of rails having openings through their Webs, of acne-piece base block having an inverted T-shaped slot extendin tudinally throughout its upper portion and adapted for the reception of the base flanges and webs of the rails, the material to each side of said slot being provided with notches alined with the openings in said rails, pins passing through said alined 'notches and openings, undercut longitudinal ribs on said base block retaining plates between said undercut ribs and the under sides of the heads of the rails.

2. The combination with the meeting ends of a pair of rails having openings through their webs, of a one-piece base block having a longitudinal rectangular base and upwardly and inwardly inclining side walls,

said block having a longitudinal inverted T- shaped slot at the juncture of said side walls for the reception of the base flanges and webs of the rails, the upper edges of said ings in said rails and opening into said slot, transverse pins in said alined notches, longitudinal undercut ribs on said side Walls of the base blocks, andlongitudi nal rail bracing and pin retaining plates forcibly contacting with the the heads of the rails and with the undercut portions of said ribs.

3. The combination with the meeting ends copies of this patent may be obtained for five cents each, by

and longitudinal bracing and pin' openings and under sides of 1,12e,pes

of a pair of rails having openings through eir webs, of a one-piece base block having a longitudinal rectangular base and upwardly and inwardly inclining side walls, said block having a longitudinal inverted T-shaped slot at the juncture of said side walls ,for the reception of the base flanges and webs of the rails, the upper edges of said walls having notches ahned with the openings in said rails and openinginto said slot, transverse pins in said alinedopenings and notches, longitudinal undercut I'lbS on said side walls of the base block, said ribs terminating at points spaced from the ends of the block,,lon'gitudinal rail bracing and pin retainingplates forcibly contacting with the under sides of the heads of the rails and with said undercut portions, said plates terminating even with the ends of the block, inclined plates overlying said inclined walls of the base block and contacting with the ends of'said ribs, and upright portions extending laterally from said inclined portions and contacting with the ends of said block and the ends of said bracing plate and fastening elements passing through said inclined plates and said base block and adapted to enter the cr oss ties.

v 4. The combination with a base block hav: ing a rail seat, a shoulder spaced laterally therefrom and a rail bracing and clampin plate between; said shoulder and the rai and terminating flush with one end of the block, of an angular end plate in contact with the contiguous ends of said bracing plate andsaid base block for preventing removal of the former.

5 The combination with a base block having a rail seat, a shoulder spaced laterally therefrom and a rail bracing and clamping plate between said shoulder and the rail and terminating flush with the ends of the block, of end plates overlying the end portions of said block and bracing plate, laterally extending portions on said end plates and in contact With'the extreme ends of said block and .said bracing plate and fastening elements passing through said end plates and said base block and adapted to enter the cross ties. I

In testimony whereof I have hereunto set y handin presence of two subscribing witnesses.
