Patented Dec.- 14, 1915.

Application filed June 3, 1914. Serial No. 842,693.

To all whom it may concern Be it known that I, RICHARD P. l/VIL- LIAMS, a citizen of theUnited States, residing at Brooklyn, .in the county of Kings and State of New York, have invented new and useful Improvements in Railway Structures, of which the following is a specification.

This invention relates to improvements in railway structures, and is particularly directed to wear'plates or corner blocks employed upon railway crossings, etc., wherein the block is removable and replaceable for the purpose of better resisting the excessive wear due to the passing of the car wheels over the same, and the primary object of the invention is the provision of means whereby the said block and retaining elements may be simultaneously removed or replaced when desired.

.Other objects and advantages of the de vice will appear as the nature of the invention is more fully disclosed, reference being had to the accompanying drawings, in which there is illustrated a simple and satisfactory reduction of the improvement to practice, it being understood, however, that the said showing is merely illustrative, and that I am not to be restricted thereto, but am entitled to allsuch changes as fall within the scope of my claims. i

In the drawings: Figure 1 is a top plan view of a railway crossing embodying one form of my improvement, the heads of the bolts and the chambers in which they are received being indicated by the dotted lines, the head of'the bolt in the upper left hand corner being arranged in the slot which communicates with the pocket to illustrate the manner in which the heads of all of the bolts are arranged when the wear plate is to be removed from the pocket of the corner block, Fig. 2 is a sectional view on the line 2-2 of Fig. 1, one of the, securing elements being turned to bring its head in register with a slot in the block, to illustrate the position of all of the bolts when the block is to be removed from the body or base, Fig. 3 is a sectional view on the line 33 of Fig. 1, Fig. 4 is a detail plan view of one of the corners of the base of the crossing, the block and securing elements being removed, Fig. 5 is a detail perspective view of a portion of the device illustrated in Fig. 4.

In the drawings the numeral 1 designates a body portion of a railway crossing or frog constructed in accordance with the present invention. The body 1 preferably comprises a substantially rectangular member and is provided, at its corners, with outwardly projecting longitudinally extending members 1. Each of the extending members 1 is channeled to provide opposite ver tical parallel walls 1 and lower horizontally straight Walls 1. The channels abut with vertical straight transverse walls 1", which straight walls 1 provide the central end walls of a horizontally straight surface 3 provided by a rectangular depression forming a pocket 3 in the body 1. The vertically straight walls of the pocket 3 are, of course, arranged at a right angle with respect to the vertically straight walls 1 of the channel members 1, and the channels in the said members 1 are provided to receive rails 2. The flanges of the rails rest upon the horizontally straight walls 1, while the opposite sides of the heads of the rails contact with the parallel walls 1*, and the tread portion of the heads are disposed flush with the upper horizontal portions of the channel memhers I as well as with the upper horizontal upper face of the frog 1. The corners provided by the depressions 2 are preferably rounded and the said depression is adapted to receive a wear plate of block 4: the same fully closing the said depression, and the block, of course, has its corners rounded to agree with the rounded corners provided by the depression. The block is formed with angularly arranged grooves which register with the wheel grooves of the rails 2.

Theblock, at each of its rounded corners, is provided with a rounded depression 5, the lower wall of each of the said depressions being formed with an angular opening 6. The floor or lower wall of the depression or pocket 3 is provided with elongated slots 7, and the openings 6 are adapted to be arranged centrally of the said slots 7 when the block a is arranged within the pocket 3. The slots 7 are provided centrally of the substantially rectangular elongated chambers 8, the same being of a greater width than the slots 7, and the upper face or wall of the pocket, to the opposite sides of the walls provided by the slots 7 are recessed longitudinally the full length of the said openings, as indicated by the numerals 9.

The numerals 10 indicate the securing bolts for the block. These bolts each include a threaded shank having one of its ends formed with a laterally extending substantially parallelogram-shaped head 11, the said head being of a width slightly less than the distance between the walls of the slots 7 and being of a thickness less than the depth offthe chambers 8. The heads 11 have their opposite ends arranged angularly, the said angular portions being in the same direclion, and being designated by the numerals 12, and the said ends are adapted after the members 10 have been arranged to bring their heads through the slots, to be turned and to contact with the longitudinal walls of the chambers 8. By such an arrangement it will be noted that the rotary movement of the heads 11 within the passages will be limited by the end walls 12 and the inclination of the said walls is such as to agree with the side walls of the chambers when the securing members are turned, the frictional engagement being su'l'licient to hold the bolts in such position to permit of the insertion of the block 4: within the pocket 3.

The block 4: is of a thickness less than the depth of the pocket 3, so that a filler of wearing material, such as Babbitt metal, may be inserted between the block and the pocket, and so provide a wear plate between the said block and pocket. In this connection, it will be noted that the sides of the block are not vertically straight, but are inclined slightly from their upper to their lower edges, While the side walls of the pocket are arranged at a right angle to the horizon tally straight lower wall of the pocket, and the Babbitt metal is inserted within the 'members 13 is provided with a semi-cylin- 50,

drical depression 1% which surrounds onehalf of each of the bolt members 10, so the said plates 13 prevent the entrance of the liquid metal to within the chambers. The shanks 10 are adapted to project through the openings 6 in the corners of the block 4, while nuts 15 engage with the said projecting ends of the shanks, and the depressions 5 are of suflicient area to permit of the insertion of a wrench or other instrument whereby nuts may be screwed home upon the bolts and the block 4: forced within the pocket,

. against the molten Babbitt metal until the same is brought flush with the face of the crossing frog or corner 1, the surplus metal passing between the inclined sides of the within the chamber and to be turned to block and the side Walls of the pocket 3. It should be stated that the openings 6 are of a greater area than the cross sectional diameter of the shanks of the bolts 10, so

should additional molten metal be required, 7-

the same can be poured through any of the said openings, the walls of the openings being greased or provided with a coating of suitable material to prevent the adhesion of the filler metal to the walls of the openings,

and likewise a coating of similar metal may be given to the underface and'sides of the block and to the lower face and'wa'lls-ofthe pocket. When it is desired to remove the cornerblock l, the application of a wrench upon the nuts 15 in a home-ward screwing d1rect1on will cause the heads-of the said bolts to rotate to bring their inclined or beveled endsout of engagement with the sides of the passage: 8 and to bring their elongated sides or walls in within theelongated slots 7. A suitable instrument ins'erted between the walls providedby the track grooves in the block or betweenthe walls 1 of the depression 5, will permit of the withdr'awal 'of the block, the liner or Babbitt metal IGand'the-bolts.

From the above description, taken inconnection with the acco1'n a'anyi-r1gdrawings,

the simplicity ofthe device as well as theadvantages thereof will, it is thought, be perfectly apparent to those skilled intheart to which such invention 'a'ppertains without further detailed description. i

Having thus described the invention, what I claim is:

l. A railway track structure including a base which has a pocket in the upper face thereof, the lower wall of the pocket having" elongated slots which communicate with rec- 'tangnlar chambers arranged within the base below the slots, a block seated within the pocket, a filler within the pocket and upon which the base rests, bolts having heads of a substantially parallelogramformation and having the end's'of their heads beveled-said bolts adapted tohave their shanks connected with the block and their heads passed through the slots to arrange their heads br'ingtheir inclined ends into frictional engage'ment with two of the oppositewalls of the chamber, whereby whenthebolts are turned to bring their heads in register with the slots, the block, the filler and the bolts we may be simultaneously removed base.

2. Afrailway track structure including a base which ha'sits upper face formed with a from the depression which provides a pocket, the 12 lower wall of the depression, adjacent the corners thereof having elongated slots which communicate with rectangular chambers 7 formed in the block below the slots, a block for closing the pocket, said pocket having beveled side walls and having openings adjacent its corners which overlie the slots and chambers, a headed bolt within each of the openings, a nut for each of the bolts, the heads of the bolts having their ends inclined and adapted to be passed through the slots and to be rotated to bring the said inclined ends into engagement with two of the opposite walls of the chamber protective plates surrounding the shanks of the bolts and arranged above the slots, and a filler of wearing metal poured within the pocket and engaging with the lower face and inclined sides of the block.

3.7A railway track structure including a base which has a pocket in the upper face thereof, a block adapted to be seated within the pocket, a filler within the pocket and adapted to sustain the upper face of the said block flush with the upper face of the base, the lower wall of the pocket having rectangular recesses arranged adjacent its corners, the lower walls of the recesses having reduced rectangular slots, the base being provided with elongated chambers arranged below and communicating with the slots, bolts having heads of a substantially parallelogram shape, the ends of which being inclined and arranged within the chamber and having their said inclined ends normally contacting with two of the opposite walls of the chamber and their shanks projecting through the slots and recesses and through the corners of the block, protective members including'a pair of plates for each of the bolts having their ends provided with semicylindrical depressions adapted to be seated within the recesses and to engage with the shanks of the bolts, and means co-acting with the block and disposed above the surface thereof and engaging the shanks of the bolts for sustaining the block upon the base, substantially as described.

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