Renewed fieptember 20, 1930.

The invention is an improved Scotch block or the like for use on railway tracks, the object being to simplify the construction and reduce the cost of manufacture as well as to improve the strength and efficiency of such devices and more especially to improve the type of Scotch bloc-k disclosed in \Vhilt Patent No. 1,369,910, which is permitted to slide on the rails under severe thrust, and

specifically it relates to pressed steel plates obliquely arranged.

The main part or body of the new block, in the form which is taken for illustration, is composed of two cheeks or plate members 1 which are reverse duplicates of each other and of such simple shape and contour that they can be formed as stampings out of plate steel, say of thickness. These plates are united in suitable relation and are supported from the rail itself. They extend upward above the rail head in posi- 0 tion where they willbe'struck by the car wheel and they seat on apart of the rail along which the device is permitted to slide, in spite of its clamping means, under the impact of the wheel. In the partlcular embodiment illustrated the plates are secured together at one end and spread divergently apart at the other, forming a tapered structure, the narrow end of which seats directly on the rail head and is shaped to form an arcuate car wheel abutment surface 4 upstandin in the vertical plane of the rail. The wi er end extends downward below the rail head and below the rail base, flanking it on each sidei being there supand transmitted edgewise through them to the saddle or to such abutment means as may be provided. Maximum strength for a given weight of Scotch block is thus obtained. The two plates may be secured to each other by rivets, as shown, with intervening spacer locks 2 and 3 between them, such blocks being tapered or wedge-shaped, both in horizontal and vertical section, as indicated and the rest of the space'between the plates being open or vacant, except for the rail, thus forming what may be termed, a skeleton structure, but of great strength. The convergent ends of the plates, in the illustrated block, come substantially or actually into contact in substantially the center plane of the rail and seat edgewise at 5, on the rail head, and the wheel abutment which they form, though narrower than the rail head is nevertheless found to be adequate, especially if the edges of the plates between the top and bottom rivets are slightly spread or bowed as indicated in Fig. 3. p

The divergent ends of the united plates preferably both extend below the rail base so as to be in position to transmit the thrust horizontally to the face of the tie, and they are supported and also tied 0r cross-connected together by a rail-su ported member which is preferably in the orm of a saddle 6 resting on the rail head with one leg depending on each side into the plane of the ties. The divergent lower ends of the two cheeks fit in thrust sockets in the depending legs of the saddle and in such way that when the plates are secured to the rail the saddle is thereby also secured in position. By this means the shock of impact may be divided and transmitted to the two legs of the saddle and by the latter transmitted to the tie.

For this purpose the saddle is widely flanged, as shown in Fig. 7, to provide a flat abutment face of extended area to engage the face of the tie; this avoids cutting the tie, The height and width of the open space within the saddle 6 is sufiicient to enable it to be set down over and upon a rail of the largest size, for example, a rail 7 high with a head or ball 3 wide with its cross part 7 seating directly on the head of such a rail, but being also adapted to seat similarly on smaller rail heads. Use is made of the interior bracing flanges 8 to narrow the space which receives the rail head, thus roughly centering the rear end of tlieblock. These flanges extend from legs 9 to the cross part 7 of the saddle as shown in Fig. 5 and the legs are long enough so that with any standard rail there will be an adequate area for abutment against the tie. The vertical dimension of the tie-abutting part of the saddle in a given case depends on the height of the rail, which in the usual range is from 4 to 7. In the construction illustrated, the plates 1 have bottom, end and top edge portions engaged to or seated in the saddle legs at 10, 11 and 12 respectively, and inside of the cars 14, 1.5 and 16 so that they are held against spreading as well as against vertical displacement. The detail of these connections will be clear from the drawing. The plates may also be riveted to the legs if desired and as shown, but it will be clear that the form of connection of plates to saddle is susceptible of considerable variation and according to preference.

The Scotch block ordinarily stands 17 above the top of the rail so as to exceed slightly the customary height of-the car wheel axis, and is narrow at its front end. Means for centering the front or abutment end ofthe block on rail heads of difierent widths is a feature of the invention and comprises the application to the plates of movable bloeks or members permanently carried thereby adjacent the rail seat 5 and which can be set or adjusted at the time of installation to change the width of the rail-headreceiving space. Centering blocks, such as identified by 17 (Figs. 6 and 9) have been found to serve this purpose etl'ectively. They are supported on pivots 19 of the brackets 18 on the respective cheek plates, being retained on the pivots by cotters 20. As shown in Fig. 9, the edge faces on each ,block are formed or slabbed at different radial distances from its turning axis, each face being at a distance corresponding to a particular size of rail head and as shown at a, b, c and d. IVhen faces a are turned toward each other the structure accommodates the smallest. size head and when other faces are used, it accommodates and is centered on other sizes of heads. hen in place on the rail, the blocks are held against turning by the rail itself. I have found that in -Scotch blocks of the tie-pushing type it is insufiicient to rely, as does Whilt, on the weight of the car wheel to counter the tendency of the car wheel abutment to jump up from the rail when the wheel hits it and to sustain it against tipping over, skewing or getting out of the central plane of the rail when it is being pushed along, these being difficulties in this type which are specially accentuated where the wheel-abutment face is carried up to the height of the car wheel axle and especially where the abutment face is narrowi} I therefore construct my Scotch block on the principle of providing means for holding it adequately against vertical movement in the plane of the rail and against transverse or lateral movement, while permitting it to slide lengthwise of the rail when required so to do, the block being thus supported while it is sliding.

It is thus true that irrespective of the details of the design and construction of the Scotch block, as illustrated and described herein, my invention consists in applying to the tie-pushing type of Scotch block of whatever structure clamping means which is substantially rigid in a lateralsense, and in the vertical sense, to prevent somersaulting or jumping on car wheel impact, but which nevertheless yields without injury to itself or the rail to motion along the rail. The clamping means is thus non-cramping by which is meant that it is of such character that the thrust of the car wheel does not tenld to tighten the grip of the block on the rai In the illustrated derail the particular means for accomplishing these stated objects is a yoke 0r loop structure which clamps the block upright on the rail and holds it against being knocked over and for this purpose makes use of the flat underside of the rail as the steadying base. In the form chosen for illustration, this securing means comprises an upper cross bar 21, and a straight lower cross bar 22, extending, respectively through the plates and under and against the rail base. The member 21 occupies holes in the cheek plates and is held against endwise displacement therein by a key 23 secured by a rivet 24 or the like; The rest of the yoke comprises the side bolts 25 extending through both cross bars and having heads 26 and nuts 27 received on plane surfaces 28, or in countersinks. The yoke is thus hung or swung from the plate structure and thereby removably clamped to the rail. To enable the block to slide on the rail, pushing the tie ahead of it means are provided to prevent binding 0% the cross bar 22 on the underside of the rail base. Such effect may be accom lished by any means which will cause the ottom cross bar 22 to move in exact unison with the top bar 21, as for example by the eyebar pull-rods 29, through whose eyes 30 the side member bolts 25 of the yoke extend and which have oiiset ends 31 which may be hooked into holes 32 in the respective plates 1. These rods pull the bottom bar along preventing cramping, i. e. self-tightening.

i As respects the non-cramping clamping means, it is immaterial whether the Scotch block has the described structure or not.

In installing the Scotch block, I provide a suitable space, of say about 20 inches, between adjacent ties. After removing the side bolt-s and lower crossbar of the yoke, the block is set on the rail with the rear face of the saddle near or against the rear tie. In order to center the front of the block the eccentric space-blocks are turned on their pivots to provide a rail-receiving space suited to the particular rail. The lower crossbar of the yoke is passed under the rail and connected by the side bolts to the top bar, after the pull rods have been put in place. It is customary to use the blocks in pairs, the members of which are located opposite each other in the track, but are unconnected, each block being supported wholly by its engagement with the rail on which it seats.

The operation will be apparent. The Scotch block, being properly centered and held upright on the rail, stress of car wheel impact on the front ends of the cheek plates is carried in their respective planes to the rear bearing or saddle and by its tie-face abutments to the tie which yields more or less depending on the nature of the ballast and as will be understood.
