' H. E JENSEN BRAKE BLOCK June 17, 1930.

Filed Dec. '27 1 92e 1W Patented June 17, 1930 UNITED srA'rss HANS E. JENSEN, F HUNTINGHFON, UTAH BRAKE BLOCK Application filed December 27, 1926. Serial no, 157,305.

This invention relates to brake means for vehicles, such as wagons, the general object of the invention being to make the brake shoe removable so that a new shoe can be substituted for an old one when the old shoe has become worn.

Another object of the invention is to provide simple means for attaching the brake shoe holders to the brake beam.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a front view of the invention, with parts in section and a part of the brake beam shown in dotted lines.

Figure 2 is a side view of Figure 1, with parts broken away.

Figure 3 is an end view.

Figure 4: is a fragmentary perspective view of the shoe.

Figure 5 is a side view showing a slight modification.

In these views, 1 indicates a holder which is composed of a block 2 and the metal strips 3 fastened to the sides thereof and extending above the face of the block, with their upper edges bent over to form guideways, the bent over port ions having extensions 4 at their ends which are bent down'and fastened to the face of the block so as to close one end of each guideway, the other end being open. The removable shoe is shown at 5 and said shoe is preferably of the shape shown in Figure 4, with its side edge slightly beveled to engage the guideways so that the center of the shoe will extend beyond the bent over portions of the plates 3, as shown in Figures 2 and 3. The lower end of the shoe is formed with the tongue 6 which forms shoulders 7 at. its junction with the body of the shoe, these shoulders engaging the closed ends of the guideways and limiting the downward movement of the shoe, the tongue extending to a point close to the lower end of the holder. After the shoe has been put in place, nails or the like are driven through the holes 8 in the flanges of the plates 3 to fasten the shoe in place. The rear face of the holder is formed with a shoulder 9 which is adapted ,e to rest against the upper edge of a brake 6' beam 10 and bolts 11 are used to connect the holder to the beam.

Figure 5 shows upper and'lower shoulders 9 formed at the rear of the holder to receive the brake beam between them. The rear part of the block may be enlarged to increase the width of these shoulders so that they will be of the same thickness or practically so, of the beam.

From the foregoing, it will be seen that to I have provided a simple and inexpensive shoe and holder, with means whereby the shoe can be removed and a new one substituted when the old one has become worn., With this invention, it is a simple matter for one to keep the brakes ofa vehicle in good condition.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent. 0

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

\Vhat I claim is In combination with a brake beam, a brake shoe or holder comprising a block of elongated contour supported on the beam, as e metallic strap terminally secured to the top 9b of block and said beam to reinforce the struc ture, a pair of plates secured to the opposed sides of the block and having their outer edges projecting beyond the face of the block and benttoward each other at an angle to said face to form a guide-way there with, each of said outer edges being curved inwardly at an appropriate point in its length in the direction of the block, and then extended longitudinally in a downward di- 1'0 rection and secured to the block to close the lower ends of said guide, a brake shoe of substantially elongated contour having a fiat intermediate surface and oppositely beveled surfaces arranged at either 'side of the flat surface to engage the inclined outer-edges of the plates as the shoe is positioned in said guide, a reduced extension projecting from the lower end of the shoe and defining shoulders at its point of juncture with the shoe, said extension projecting beyond the guide with the shoulders resting upon the inwardly curved portion of said edges.

' In testimony whereof I afiix my signature.

HANS E. JENSEN.
