means whereby a partially worn shoe may` .be secured to the wearing face or body of an' entirely new shoe, in Order that said partially worn shoe may be completely andentirely worn away or used up. l
Wit-h this and other ends in view, the invention consists in certain novel features of construction and combinations of parts,
as will be hereinafter fully described andl pointed out in the claims.
In the accompanying drawings, Figure 1 is a plan view of a brake Shoe constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view thereof taken on the line 2-2 ofFig. 1. Fig. 3 is a view in cross sect-ion taken on the line 3 3 of Fig. 1. Fig. 4 isa longitudinal sectional View taken on the line 4 4 of Fig. 1, and
`showing a 'partially worn shoe attached to a new shoe. Fi 5 is a view 'in cross section taken on the line 5 5 of Fig. 4. Fig. 6 is a detached View in perspective of the keylug. Fig. 7 is a plan View of a modified form of the shoe, showing the key-lug retaining loops formed from a single piece of wire. Fig. 8 is a sectional view thereof taken on the line 8 8 of Fig. 7. Fig. 9 is a'plan view of another modified form showing the key-lug extending transversely across the shoe. Fig. 10 is a longitudinal sectional view of a part of the shoe shown in Fig. 9, and taken on the line 10 10 of Fig. 9, a partly worn shoe being attached to the wearing face of a nenl shoe. Fig. 11 is a sectional view of the same taken on the line 11 11 of Fig. 10. Fig. .12 is a detached view in perspective of a sectional strengthening back adapted for use in connection with my improved shoe illustrated in perspective in Fig. 13. Fig. 13 is a view in perspective of my improved shoe adapted for use in connectionwith a removable strengthening back. Fig, 14 is a cross sectional view thereof, showing the removable back applied to the shoe. F ig. 15 is a view in cross section .taken on .the line 15 15 of Fig. 14. Fig. 16 is a view in perspective showing my improved' shoe made to receive a di'erent form lof detachable strengthening back, one section'ofl said back being detached from the shoe proper.
7,/ By reference to the drawings, it will be seen that the shoe comprises a body 20, preferably formed of cast iron, and if desired,
has embedded or partially so at or adjacent x to the back thereof, wire mesh or expanded metal 21, in order to hold together the fragments or sections of the body 20, should the same become cracked or injured in service. The body is also provided with the usual stop and guide lugs 22 near its extreme ends. To the shoe is also,attached a key lug 23, the shape and contour of which is clearly illustrated in perspective in Fig. 6 of the drawings. This lug, preferably made of cast metal, is formed with the sides 24 having recesses 25 provided therein, and with the transverse or top plate 26 scored or recessed y as illustrated at 27 in order that the same may be purposely fractured or broken on the transverse line of said latter` recess. When the parts are assembled, the lower ends of this key-lug rest upon the back of the body 20, as clearly illustrated in Figs. 3 and 5 of the drawings, and is retained in its proper position by means of the wire loops 28, the ends of which are embedded and anchored in the body of the shoe, as illustrated in Figs, 2 and 4.
In the body of the shoe, and in the wearing face near the ends thereof, are formed the recesses or cavities 29, of such depth and outline as to receive and contain the stopv and uide lugs formed on the back of a simiarly constructed shoe, and in the body of the shoe are also formed the slots or openings 30, these openings, which may extend entirely or part way through said body, being located about midway the length of the shoe, in order to receive and contain the wire loops 28 of a partly worn'shoe when attached to the new shoe. In the openings 30 are formed shoulders 31, Fig. 3, over and upon which rest the wire loops 28, thereby vsecurely locking the partly worn shoe to the new shoe, and preventing their accidental disengagement, as illustrated in Fig. 5.
In practice, when it is desired to attach a shoe partly worn away in service, to the wearing face of a new shoe, the key-lug 23 is detached from the partly worn shoe by breaking it along the recess or score 27, whereupon the two-sections or fragments may be easily and readily withdrawn or disengaged from the retaining loops 28. The partially worn shoe thus relieved of lthe key-lug, is then attached to the wearing face of, a new shoe by inserting the retaining loops 28 in the openings 30, the wires forming the loops being slightly pressed or sprung together until they reach the shoulders 31, whereupon they spring outwardly to their normal positions, and over and upon said shoulders, as 'clearly illustrated in Figs. 4 and 5, the stop and guide lugs 22 fitting in the cavities 29. The parts thus assembled, may be ,used in service until the partly worn shoe is entirely worn away, and until the new shoe is partially worn away, whereupon the key-lug of the latter may be fractured and removed, as in the first instance and the then partly worn shoe attached to the wearing face of a new shoe.
It will be evident to those skilled in the art, that my improved shoe is capable of modification in several respects, without in any way detracting from the eliiciency thereof, as for instance, as illustrated in Fig. 7
of the drawings, the retaining loops, instead Cir of being made of two separate pieces of Wire, as illustrated in the previously mentioned gures of the drawings, may be constructed of a single piece of' wire 32, this single wire running longitudinally nearly the entire length of the shoe and parallel with the edges or sides of the body, the wires about midway of their length beingl bent up into retaining loops 33.
In either of the above instances, that is, in the shoe as illustrated in Figs. 1 to 4, or 7 and 8, instead of employing a key-lug 23 with the wire retaining loops, said lug may be omitted `and a sectional strengthening back employed with the loops, as illustrated in Figs. 12 to 16.
By reference to Figs. 12, 13 14 and 15, it will be seen that the body of the shoe may be made with the guide lugs 34 under the ends 35 Aof which may fit the ends of the sections 36 of the sectional strengthening back, the outer ends 37 of these sections being upwardly turned to form stops, and the inner ends 38 upwardly bent to form a keylug, as clearly illustrated inv Fig. 14. The shoe 'in this instance, however, will be constructed as in the preceding forms, with openings 38a provided with the shoulders 39 for the reception and retention of the wire loops 4() of a partly worn shoe when assembled with a new one. The body of the shoe will also be formed with the recesses 41 near its ends, for the reception of the lugs on the back of the new shoe.
Instead of providing the back of the shoe with the lugs 34, as above described, it may be provided with under-cut recesses 42, as illustrated in Fig. 16, the sections of the strengthening back being dove-tailed or beveled to slide into the same. Again, instead of having the wire retaining loops run lengthwise of the body ofthe shoe, they may be arranged transversely, as illustrated in Figs. 9, 1() and 11, in which instance the loops 43 alone may be employed as the keylug, the ends of the wires 44 from which these loops are formed being embedded in the body of the shoe. As in the several forms of shoes already described, the shoe in this instance will be provided with the openings 45 and shoulders 46 for the reception and retention of the wire loops forming part of the new shoe'to which the partly worn shoe is assembled, as clearly illustrated in Figs. 10 and 11.
From the foregoing it will be seen that my improved brake shoe is simple in construction, economical to manufacture, and that the means provided for looking the partly worn shoe to the new shoe are efficient and certain in their operation, overcoming all danger of the assembled parts becoming accidentally disengaged in service.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is
1. A brake shoe of the character described, the body of which is provided with openings for the reception and retention of wire loops attached to the body of a similar shoe when assembled therewith, substantially as described.

4. A brake shoe comprising a body, a keylug removably attached to said body, and means permanently attached to said body for holding the removable key-lug in position. v
5. A brake shoe comprising a body, a keylug thereon and adapted when broken to be removed from the body, andmeans for holding the unbroken key-lug' in position.
6. A brake shoe comprising a body, a keylug thereon and adapted when broken to be removed from said body, and means permaceases nently secured to the body for holding the unbroken key-lug in position.
