RAILWAY APPLIANCE.
Specification of Letters Patent.
Patented Feb. 2c, 1917.
Application filed April 3, 1916, Serial No. 88,567. Renewed November 25, 1916. Serial No. 133,485.
To all whom it may concern: I
Be it known that I, CHRISTOPHER E. WEN- RICH, a citizen of the United States of America, and resident of Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Railway Appliances, of which the following is a specification.
This invention relates to railway appliances and particularly to railway chocks, the said invention having for its object the provision of novel means for renewing the braking surfaces of such chocks and for augmenting the friction between the chock and the rail on which it travels, thereby insuring more positive action of the said chock in arresting rolling stock when the wheels contact the same.
A further object of this invention is to produce novel means whereby the friction or contacting surface of the chock may be adjusted with relation to the body of the chock, thereby increasing the length of service of a shoe or plate which is attached to the body.
A still further object of this invention is to provide a chock with a body having a detachably connected shoe, the said shoe being held in place in a manner to insure more positive interlocking engagement with the shoe and body, proportional to the movement of the said body.
With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.
In describing the invention in detail,
reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a view in perspective of a chock embodying the invention;
Fig. 2 illustrates a sectional view of the chock with the wheel applied thereto while the chock is shown on the rail;
Fig. 3 illustrates a sectional view on the line H of Fig. 2;
Fig. 4 illustrates a sectional view on a line corresponding with the same line of Fig. 2
but embracing a modification;
hFig. 5 illustrates a perspective view of the s cc;
Fig. 6 illustrates a perspective view of the shoe retaining strip; and
Fig. 7 illustrates a perspective View of a shoe differing in configuration from that the said recess corresponding in length to the lengths of the flanges 9' and 10 so that the recess is practically co-extensive with the flanges.
Near the lower edges of the flanges, there are ribs 12 and 13 respectively forming shoulders or ways on which the flanges 14 of the shoes 15 may rest or on which the spacing strips 16 may rest when such spacing strips are interposed between the flanges 14 and the ribs 12 and 13. Thus, as shown in Fig. 3 of the drawing, the shoe with the abrading material is held at certain spaced relation to the ribs and when the lower surface of the shoe becomes worn and it is desired to lower the surface of the shoe which contacts with the rail, the strip 16 may be removed and the flanges 14 of the shoe '15 may be brought into engagement with the ribs, the spacing or retaining strips .16 being then inserted above the flanges 14 so as to hold the abrading material in proper position with relation to the bottom of the body of the chock.
In Fig. 4, the body 17 of the chock has the flanges 18 and 19 similar in all respects to the flanges shown in Fig. 3, but in the modified construction, the abrading material or shoe 20 rests on the shoulders carried by the flanges and thereis a backing strip 21 interposed between the shoe and the bottom of the body, thus holding the shoe in proper position.
It will be understood that the abrading material or shoe as contemplated in this invention may consist of sandstone, emerybrick or metal serrated or otherwise roughened to increase the frictional contacting surface thereof with the rails.
The shoe or abrading material has its end abutting a shoulder 22 which constitutes the end wall of the recess and as the chock moves longitudinally of the rail, the action is to more firmly force the end of the abrading material into engagement with the shoulder so that dislodgment of the abrading material is obviated.
I claim:
1. In a chock, a body having a recess in its under surface, flanges extending downwardly from the sides of the said b0dy,said
flanges having shoulders thereon, an abrading plate slidable longitudinally of the said shoulders in the recess of the body, and
spacing strips interposed between the shoe 1:
ing plate slidable longitudinally of the said shoulders in the recess of the body, and a packing strip interposed between the wall of the recess and the said abrading material. In testimony whereof, I affix my signature in the presence of two witnesses.

CHARLES W. LIPPERT, HARRY E. BENDER.
