BY www Patented June 28, 1932 UNITED STATES PATENT OFFICE v STANLEY W. HAYES, OF RICHMOND, INDIANA, ASSIGNOR TO TRACK APPLIANCE COMPANY, OF RICHMOND, INDIANA, A CORPORATION OF INDIANA scoren BLOCK Application filed October 18, 1930. Serial No. V489,524.

The invention is an improved and simplied scotch block or the like for use on railway tracks, and is primarily applicable to the type of scotch block disclosed in the Whilt Patent No. 1,369,910 and in which parts-of the block extend below the base of the rail into the plane of the ties `to insure dissipation of the shock of car wheel impact to the ties and/or ballast. Y The scotch block of this application also embodies certain aspects of the scotch block disclosed and claimed in the co-pending application of the present applicant iiled- August 8, 1929, Ser. No. 384,260, and which issued April 21, 1931 as Patent No.

1,801,917. It is furthermore of the type of car stop applicableto the rail without drilling it, thus avoiding rigidity, and as it is capable of sliding o n. the rail under severe shock and carries the stress of such shock to the tie and ballasts, it atl'ords a springy, shock absorbing resistance or cushion eliminating or minimizing damage to the car or to itself.

Referring to the drawing: Fig. 1 is a perspective view of one of the scotch'blocks in place on the rail;

Fig. 2 is a perspective on a larger scale showing the principal members of the scotch block ready for assembling;

Fig. 3 is a front sectional elevation in the vertical plane of the clamp screws showing the block applied to the heaviest rail for which it is adapted;

Fig. lis a rear .elevation partly in section corresponding to Fig. 3; and

Fig. 5 is a front elevation, showing the block applied to a light rail.

In the preferred form of the block which is that illustrated there are but three main parts yseparately made and integrally united 401 by welding. These are the block proper or car wheel abutment member 1 and the inverted

U members

2 and 3, all most cheaply made from flat'steel stock of appropriate weight. The abutment member 1 may be stamped from sheet steel, or cut out from a rolled sheet steel plate by oxy-acetylene flame, or otherwise given the desired' contour.

The front edge of this'plate constitutes a carv wheel receiving abutment 4. The

other parts

2, 3, are formed by bending fiat strips of steel into U-shape.` They are then applied to I Y straddle the rail when the scotch block has.

been applied to it.' The member 2 supports block centering and holding means and the member 3 transmits car wheel thrust to the tie and/or ballast. The block 1 extends up from the rail top a distance of 16%,, or to substantially the height of the car wheel axis, so'as to preclude overrunning of the block by the wheel. Its height thus produces or accentuates upward turning moment of the front end of the abutment and necessitates provision of meansfor resisting-.such moment. The'block also has special need to be supportedV against lateral displacement as well as against jumping off the rail or. skewing on initial cai wheel impact. Furthermore, on such occasions as itis forced ahead of the wheel displacing the tie, its movement must be guided and kept straight by the rail as a guide, and its accidental removal from the rail must be prevented. These offices are performed b v centeringr means associated' with the member 2, in the form of

opposed screws

7, 8, bearing 'with their flat ends against opposite sides of the rail head. and by` the clamping screws 9, 10, also opposed and bearing on opposite sides of the rail web beneath. and in the largest rail. partly against the underside of, the rail head This clamps t-he block 4in upright positionon the rail, and firmlyV against lateral movement, and with the largest rail, clamps the block down on the rail head, but clamping downward on the rail head has been found not to be necessary; a Vertical play offan inch or so, such as indicated in Fig'. 5 does no harm, and thus the singlev pair or web clamping'bolts suffices for the Vseveral weights of rail, with which the device may be used.A With any weight of rail within the-range for which the scotch block is designed the clamping Ameans is adapted to co-operate with the head of the rail to limit upward movement of the block on car wheel impact. If initially in contact with the head of the rail, the clamping means limits the movement to almost if not literally zero. Although the block shown in Fig. 5 functions properly, additional screw holes for bolts 9, 10, so located as to insure contact of the screws with the underside of the head of a. lighter rail may be -provided, as indicated by dotted lines at 11. The screws may have lock nuts as shown at 12. There is no cramping action of the device under car wheel thrust, the effect of the screws being vmerely to hold the car wheel abutment l in its proper position on the rail permitting it to be moved endwise thereon when occasion requires. During such movement the rear or tie abutment faces of the lrail strad-dling member 3 transmit the wheel thrust to the tie and ballast affording yielding resistance least injurious `to the rolling stock. e The scotch blocks, it will .be understood, are customarily placed in pairs opposite each other in the track. The nature of the ballast of course determines the extent of the yielding or cushioning action, a tie moving more readily in light cinders and less in stone, but the movement need not be great; half an inch will absorb much shock.

The simplicity, cheapness and ease of installation of this scotch block will be evident. All its parts are, or may be, virtually stock, the three sheet or plate members being of say l steel plate, and the screws being ordinary screws, Sav 1%. 1While the block as illustrated is preferred, it will be apparent that some of its features could be used to advantage in car stops of other types.
