To all whom it may concern:

Be it known that 1, MICHAEL P. MURRAY, a citizen of the United States, residing at Gresson, in the county of Oambria and State of Pennsylvania, have invented new and useful Improvements in Railroad-Clamps, of which the following is a specification.

1 This invention relates .to railway tie plates and consists in the peculiar construction, arrangement and combination, of parts which will be hereinafter fully set forth and claimed.

The object of the invention is to provide a tie plate for railway rails which is extremely simple in construction, which can be manufactured at a comparatively low cost, and which will perform the functions for which it is intended with ease and accuracy.

In the accompanying drawings, Figure 1 is a perspective view of a tie plate constructed in accordance with the present invention, the same being shown attached "to the tie and a rail being indicated by the dotted lines. Fig.2 is acentral longitudinal sectional view of the tie plate. Fig. 3 is a perspective view of one of the members comprising the plate. of the eo-acting member. Fig. 5 is a sectional view of a modified form of the device.

As illustrated, and as preferred, n1y tie plate comprises two main parts or members designated by the numerals 1' and 2. Both of these members 1 and 2 are of a substantially rectangular form. The member 1 is provided'on its upper surface and at one end thereof with a centrally located enlargement 3 having an upwardly and inwardly projecting rail flange engaging member 7. This enlargement extends inwardly a short distance. The tie plate 1 is centrally cut away from the inner Wall 4 of the enlargement to its opposite edge, thus forming a longitudinal opening 4*. Each side wall of the opening et lies in the plane of the cone sponding slde face of the enlargement, 3 and the overlying rail flange engaging member The overlying member 7' forms, with the upper surface of the enlargement 3, a pocket 7 for the reception of the rail flange. enlargement 3 is provided with a vertically disposed rectangular opening 13 positioned outwardly with respect to the pocket 7* and adapted to receive a tie retaining spike. The member. 1 is also provided at eachside of the enlargement 3 with a rectangularvertical spike opening .6 and is-further proy'ided Specification of Letters Iiatcnt.

Application filed February 1a, 1921. Serial .tqo. 603,539.

Fig. 4 is a similar view The .largement 3 on the member 1. ness of thc member 2 at the enlargement.

12, is equal to the height of the enlargement Patented'hlov. 26, 191% adjacent its other extremity with similar spike openings 5 positioned on each side of the longitudinal opening 4 The member 2 is of similar area to the member 1 and is centrally provided on its under surface adjacent one end with a longitudinally extending enlargement 12. .This enlargement is of a width equal to the width of the longitudinal cut-away portion or opening a in the member. 1. The member 2 is provided on its upper surface and at the same end with an upwardly and inwardly projecting Each side Wall of the longitudinal opening 1 1 lies in the plane of the corresponding side faces of the member 9 and enlargement l2, and is therefore equal in width to the openingl in the member 1. The enlargement '12 in the member 2 is provided with avertical rectangular spike receiving opening 14 which extends upwardly through the memher 9 but is positioned out-wardlywith respect to the pocket 10. The member 2 is provided at each side of the member 9 where it joins the same with a vertical rectangular spike opening 15. Similar spike openings 15 are provided adjacent the opposite end of the member 2 at each side of the opening 11.-

hen the members 1 and 2 are assembled in rail engaging position the enlargement 12 of the member 2 fitsinto the opening P of the member 1, so that its outer face The flange engaging is flush with the outer face of the extremity of the member 1, and theside walls of the cut-away portionin the opposite end of this "member 2 engage the sides of the en- 3 on the member 1, so, thatwhen these -niembers are assembled the upper surface of said enlargement 3 will lie iu the plane of the upper surface of the member 24 The thickthese surfaces forma united bearing surface for the base of the rail. In this position of thetwo members the overlying-members 7 and 9 project inwardly toward each other so as to' engage the upper surfaces of the rail flanges, and the spike receiving openings 15 in the member 2 are in alinement with the similar openings 5 in the member 1.' The spike openings 15 in the member 2 are also in alinement with the openings 6 in the member 1. When the two members are assembled in this manner, as shown in Fig. 1, with a rail base resting on their upper surfaces and having its flanges received by the pockets 7 and 10.0f the two members, and spikes are driven through their respective. openings into a supporting tie, the joint thus formed is very compact and strong.

In Fig. 5 I have illustrated a slightly modified form of the device; Inthis figure the clamping 'means 'comprises a pair of members17 and 18, each of these members being constructed of a single sheet of ma '.terial v The member 17 is bent-inwardly upon itself toform an overlying portion .19, and'themem issimilarly bent upon itself to form an overlying portion 20. The overlying portion 20 of the member 18 is flattened upon the said plate for a short distance and then extends upwardly at an angle to form the'rail flange engaging member 22. The overlying portion 19 of the member 17 is flattened for a short'dis-, tance and then extends upwardly at an angle to' form'the rail flange engaging member 21. When the member 18 is placed upon the member 17 and its end is slid into. the enlarged angle or pocket ofthe member 17 the rail flange engaging members are in operative position, The member 17 is provided with 'a spike receiving opening which extends upwardly through its flattened overlying portion 19- and is also provided adjacent its opposite extremity with a similar spike opening. The member 18 is provided with a spike opening which extends upwardly through the flattened overlying portion 20 and is adapted toregister with the opening in the end of the member 17 when the two members are assembled,

From the above description, taken in con-' i Leaenee nection withS thev-aecoinpanying drawings, it Will be noted. .th

surface and atone extremity witha central enlargement, said plate being provided with a longitudinal slot extending. from the-inner face of said enlargement to the opposite exat I have provided an tremity of the .plate and being equal in width to said enlargement, an inwardly extending engaging member formed on said enlargement and overlying the same, said plate being provided with a vertical spike opening extending through its engagingmember and enlargement, said plate being further provided with a verticalspike opening adjacent each corner thereofla second superimposed plate provided on its under surface and at one end thereof with a depending central enlargement adapted to be slidably received by the slot in the first plate, said second plate being formed with a longitudinal slot extending from the inner edge of said enlargement to the opposite end thereof and adapted to" receive slidably the enlargement on the first plate,

, and an inwardly extending engaging member formed on said second plate above the depending enlargement and overlying the said slot, said second plate being provided I with a vertical spike opening extending through its enlargement and engaging member, and further provided adjacent each corner with a spike opening adapted to aline with the corresponding spike openings in the first plate when-assembled,

In testimony whereof I affix my signature in presence of two witnesses;
