BRAKE-SHOE.
This invention relates to brake shoes, and
my present embodiments relate more particularly to that type or'class 'of brake shoes known as interlocking shoes, wherein the back and face .of theshoes are provided with interlocking means, whereby a partially worn shoe can be detached from the head and applied to the wearing face of a new shoe, so that the partially worn shoe may be completely used up.
One of the novel features of my present invention resides in a construction wherein the interlocking parts on the back and face of the shoe respectively are of such a character that two similar shoe bodies or one whole shoe body and another partially worn shoe body can be brought into interlocking relation by placing the bodies with the face of one against the back of the other, and giving them a slight relative longitudinal movement, so as to bring the interlocking parts into cooperative relation. In the present invention the interlocking parts are so constructed and arranged that the shoe bodies may be interlocked by imparting a relative longitudinal movement to the bodies in either direction, that is, when the bodies are properly positioned with the face of one against the back of the other, they may be Specification 01 Letters Patent. -App1icaticn filed January 18, 1911.
Patented Nov. 28, 1911. Serial No. 603,267.
lugs I have equipped the back of my improved shoe with a plurality of transversely arranged ribs, spaced from the centrally disposed attaching lug a sufiicient distance to enable the attaching lugs of the brake head to. be positioned between these ribs and the attaching lug on the shoe, so that the sides of the lugs of the' brake head will be engaged by said transversely disp sed ribs and the ends or sides of the attaching lug of the shoe thereby preventing the shoe from-being displaced or thrown out of alinement. v
other novel features of construction and many of the objects and advantages of this invention will be apparent as it becomes better understood from the following description when taken in connection with the accompanying drawings, illustrating prelnterlocked by moving one of the bodies;
2 central locking shoulder.
relatively to the other longitudinally in either direction. This construction'p'ermits l -most on the brake head.
Another feature of my invention consists in eliminating the usual guide and thrust lugs which are ordinarily provided to engage with the end prongs of the brake head for the purpose of preventing the shoe from becoming displaced or thrown out of alinement. In lieu of the usual thrust and guide the shoulder,
ferred embodiments thereof.
Referring to the drawings,Figure 1 is a side elevation of a brake shoe embodying my invention, the shoe being shown as attached to a brake head; Fig. view of one form of my improved shoe; Fig. 3 is a bottom view thereof; Fig. 4 is a View similar to Fig. l, of the shoe; Fig. 5 is a sectional elevation on the line 5.5 of Fig. 4: Fig. 6 is a sectional elevation on the line 66 of Fig. 4; Fig. 7 is a detailed fragmentary sectional view on the line 77 of Fig. 4, showing one locked position of the means for locking two shoe bodies together; and Fig. 8 is a View similar to Fig. 7, showing another locked position of said locking means. Fig. 9 is afragmentary plan View of the central port-ion of a shoe showing the shape of the On the drawings,
10 designates the main body of the shoe on the back of which and disposed centrally thereof is provided a projecting shoulder 11 (Fig. 5). The central portion 12 of the side Walls of this shoulder is disposed at right angles to the base 13 of while the end portions 14 of the walls are undercut to form a dove-tail connection with a detachable undercut attaching lug 15 or with the recess 0n the face of a similarly shaped shoe. The side walls showing a modified form 2 is a top plan of a centrally disposed recess 16, w th which a shoulder constructed as above described is adapted to interlock, are undercut at 17 in the center and adjacent the ends of the walls,
.leaving between such undercut portions be evident that after such shoulder has been one end and the centrally undercut portion.
.inserted into the recess, the bodies may be moved longitudinally in either direction to efiect locking engagement between the shoulder and the undercut walls of the recess.-
Such relative longitudinal movement will dispose the undercut end portions of the shoulder in interlocking engagement with of the side walls of said recess.
Spaced from the locking shoulder 11 and upon either side thereof, I have provided transversely arranged ribs 18. These ribs are adapted to perform the function of the usual guide and thrust lugs in preventingdisplacement of the shoe and maintaining the same in proper alinement, and also to space one shoe away from another shoe when interlocked. I
From Fig. 1 it will be apparent that the attaching prongs 19015 the brake head 20, which is of a well known type, fits snugly between the sides of the shoulder 11 and the transverse ribs 18. The close engagement between the prongs l9 and the ribs 18 will prevent the body of the shoe from twisting relatively to' the head sufliciently to be thrown out of alinement. It will be evident that this construction obviates the usual guide and thrust lugs which customarily engage with the end prongs 21 of the brake head for the purpose of maintaining the shoe in alinement. s
Upon and integral with the back of the shoe and between the ends thereof and the ribs 18, I have provided locking lugs 22 of a general shape and contour shown in Figs. 2 i and. 8. The portions 23 of the side walls of-these lugs are disposed vertically .with respect to the back of the shoe, while the parallel portions 24 and the tapering portions 25 are undercut forthe purpose of effecting interlocking engagement with suitably shaped recesses provided on the face of a similar shoe body. In addition to the centrally disposed recess 16 which has been previously described, the face of the shoe is provided with recesses 26 of the same general shape and contour as the locking lugs 22, with which the side walls of the recess interlock- 'ingly engage. The wider portion 27 of these rrecesses has vertical side walls while the narrower portion 28 and the tapered portion 29 has undercut side walls for engagement with the undercut portions 24 and 25 respectively of the locking lugs 22.
VVhen it is desired to attach a new or a partially worn body to the face of a new shoe on the brake head, the back of the body to be attached is so positioned against the face of the other body that the wide portion of the locking lugs 22 between the undercut walls 24 will slip into the recess 26 between the vertical walls 27 thereof, the
tapered portions of the lugs slipping into the tapered portions of the recesses. If now the movable body member or in other words,
the member to be attached, be moved longitudinally of the new member toward the right, viewing Figs. 1, 4 and 7, theundercut portions 24 and 25 of the lug 22 at the-right end of the shoe will lockingly engage with the undercut walls 28 and 29 respectively of the corresponding recess 26, while the under- I cut walls 24 of the lug 22 at the opposite end 'of the body will lockingly engage with the undercut walls 29 of its respective recess 26. This relative longitudinal movement of the body members will also bring the undercut portions 14' of the shoulder 11 into locking engagement with the undercut portions 17 of the walls of the centrally'di'sposed recess 16.
Should the body members be moved relatively in the opposite direction from that above indicated, the undercut portions 24 of the lug 22 at the right end of the body will engage with the undercut walls 29 of the recess 26 in the relation shown in Fig. 8, while the lug and recess disposed at the opposite ends of the members will'lockingly engage in the position shown in Fig. 7.
It is thus apparent that when the locking lugs areinserted into their respective recesses, the body'members may be rigidly.
locked together by moving said members relatively and longitudinally in either direction.
As shown in Fig. l the ends of the back of the removable shoe body lie flat against the ends of theface of the fixed shoe, while the central portions of the shoe are spaced some little distance apart, the ribs 18 Qnthe old shoe acting as spacing ribs to insurethispermitting a thinner shoe to be employed and insuring greater transverse strength thanwould be secured were the face of the shoe deeply socketed at this point.
-' In Fig. 4 the ends of the bodies at their back are provided with spacing ribs 30- which also insure separation of the shoes throughout their length, thereby reducing the depth of the recess 26 and proportionately increasing the strength of the shoes at this point. Invthis modification of the shoes, the ribs 18 are necessarily somewhat longer than the ribs shown in Fig. 1,.which construction not only decreases the depth of the central recess or socket 16but also insures a more rigid engagement and greater nevertheless be obvious that slight changes I and dimensions 7 and variations in the form of the parts herein shown and described can be made Without departing of the invention or sacrificing any of the material advantages thereof.
