J. F. MCDOWELL CAR STOP Filed Jan. 51, i955 Sept. 24, 1957 av 3o INVENTOR. James E McDowe/L W ATTORNEYS.

United States Patent Office Patented Sept. 24, 1957 AR TOP James F. McDowell, Kansas City, Kans., .ass ignor to Wasco Supply Compa y, Kansas City, Kans., a corporation of Nebraska Application January 31, 1955, Serial No.485,01,1 2 Claims (Cl. 104-258) This invention relates to .car stops, and more particularly to stops for attachment to rails for stopping of railroad .cards.

H r of I va io apparatuse have been used fo ppin of railroad cars and th l e and th mos common h v be n teps w ch ext n abov th ai conside a l dis n and h s memb for ng g n the e d o the car for stopping the same, .thus providing a bumper a ains h m i po -ion of t rail oad car a-th. r tha the wheel.

The principal object of the present invention is to provide .-a :stop et achah t the railroad rail h g a gripping action in combination with a wedge member whereby the more pressure exerted on the stop proper by the wheels of the railroad car, the tighter the stop will grip the rail.

Other objects of the present invention are toprovide a stop in -two;pieces having jaws for engaging the head of a railroad rail and having a tapered space between the upper portion of the jaw and the head of the rail to receive a wedge; to provide means for clamping the two piece stopmember on the rail; to provide means whereby one of the pieces may be adjusted with respect to the other to fasten the sections together; to provide strengthening ribs on the jaw portion of the stop; and to provide a device of this character which will be selftightening when contacted by the wheels of the railroad car and one which is simple and economical to manufacture.

In accomplishing these and other objects of the present invention, I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings wherein:

Fig. l is a side elevational view showing my stop attached to a railroad rail.

Fig. 2 is a cross-sectional view taken on a line 2-2, Fig. 1.

Fig. 3 is a cross-sectional view taken on a line 3-3, Fig. 2.

Referring more in detail to the drawings:

1 designates a car stop embodying the features of my invention adapted to engage the head of a car rail so that the wheel of a railroad car may contact the same for stopping the car at the desired place. The stop proper comprises two

mating sections

2 and 3 having their lower sides elongated and formed so as to provide facing

jaws

4 and 5 for engaging the head 6 of a railroad rail 7. It will be noted the lower faces of the jaws provide flanges 8 and 9 which engage the underneath sides of the head as indicated at 10 and 11 for retaining the stop on the rail. The flanges are spaced from the upper portion of the jaws providing a space 12 between the rail and the upper portions of the jaws as indicated at 13. The jaw portions are tapered as illustrated in Fig. 1 so that the space above the rail head will also be tapered for a purpose later shown.

Sections

2 and 3 are provided slightly above the jaw portion thereof with spaced

openings

14, 15, 16 and 17 for receiving belts or the like 18 retaining the device on he l- T sec on e longa ed a d he ve t ca po io s a d are som w a of a t an ula h pe w o s d 20 the e r u ded a n ica e at 2 to u stan a ly e sh p o a a hoae t a whee (not sh wn) hic pr d s k n surface fo such Wheels T e upp po t on .2 o the se io s is pr ded it an opening 2 t r c a bo 4 .for clampin the sect on ethe A p ali y o Was ers 2- e Pro ded :fo t e b l 24 so h he uppe po tion of t e sections ma be pac d a d in su tanti l y e t ca P0 lowe p o the eof du to th poss i ty o he hea of t ails bei g o d f erent dimensions,-

The openings 14 and 16 in the section 3 are also elongated so that the shank of the bolt near the head 29 will engage in such openings. The bolts 18 are known as hack bolts and the shanks are flattened as indicated at 18 to fit the

holes

14, 15, 16 and 17 to prevent turning thereof in the openings. The

elongated jaw portions

30 and 31 are provided with a plurality of vertical ribs 32 for strengthening the jaws and also to provide a symmetrical structure. There is a substantially triangular opening 33 in the sections and the forward and rear outer edges are also provided with

ribs

34 and 35 to add strength to the sections. I

It will be obvious from the foregoing that the tapered angles of the wedge and in the wheel stop castings or sections result in a self-tightening action when the stop is contacted by the wheels of a railroad car.

It will further be obvious that I have provided an improved car stop easilyand quickly assembled on railroad rails for the purpose set forth.

What I claim and desire to secure by Letter Patent is:

1. A railroad car stop for attachment to the head of a rail having a base flange with an upwardly extending web terminating in a rail head having substantially parallel side faces and bottom surfaces inclined outwardly and upwardly from said web comprising, two mating sections each having elongated lower portions with facing jaw surfaces for engaging the side faces of the rail head, means on said lower portions of the mating sections for engaging the inclined bottom surfaces of the rail head, said mating sections each having vertically extending upper portions offset inwardly from the respective facing jaw surfaces and providing lower faces spaced upwardly from the rail head, said upper portions having a plurality of openings above said lower surfaces, bolt means extending through said openings for securing said mating sections together and clamping the facing jaw surfaces on the side faces of the rail head, means adjacent the upper end of said upper portions for holding said upper portions in spaced substantially parallel relation when the facing jaw surfaces are in clamping engagement with the sides of the rail head, said mating sections being so constructed that when the means on the lower portions thereof engage the bottom surfaces of the rail head the lower surfaces of the vertically extending upper portions and top face of the rail head define a space tapered longitudinally of the rail throughout the length of the mating sections, said lower faces being inclined laterally inwardly and upwardly from the respective facing jaw surfaces, and a wedge of substantially the same length as the lower portions of the sections and of a width less than the width of the rail head, said wedge having upper and lower surfaces spaced and shaped to correspond to the tapered space between the top of the rail head and lower surfaces of the upper portions of the mating sections whereby tightening of all of the bolt means will clamp the jaw surfaces on the side faces of the rail head and the wedge to the top of said rail head and striking the sections will tighten the sections on the wedge and rail throughout the length of said sections.

2. A railroad car stop for attachment to the head of a rail having a base flange with an upwardly extending web terminating in a rail head having substantially parallel side faces and bottom surfaces inclined outwardly and upwardly from said web comprising, two mating sections each having elongated lower portions with facing jaw surfaces for engaging the side faces of the rail head, flanges extending inwardly from said lower portions of the mating sections and having inclined upper surfaces thereon for engaging the inclined bottom surfaces of the rail head, said mating sections each having vertically extending upper portions offset inwardly from the respective facing jaw surfaces and providing lower faces spaced upwardly from the rail head, said upper portions having a plurality of spaced openings adjacent to said lower surfaces, bolt means extending through said openings for securing said mating sections together and clamping the facing jaw surfaces in engagement with the side faces of the rail head, means adjacent the upper end of said upper portions for holding said upper portions together in spaced substantially parallel relation when the facing jaw surfaces are in clamping engagement with the side faces of the rail head, one edge of the mating sections having a curved surface substantially on a radius corresponding to the radius of the peripheral surface of a wheel of a railroad car for engagement thereby, said mating sections being so constructed that when the flanges thereon engage the bottom surfaces of the rail head the lower surfaces of the vertically extending upper portions and top face of the rail head define a space tapered longitudinally of the rail throughout the length of the mating sections, said lower faces being inclined laterally inwardly and upwardly from the respective facing jaw surfaces, and a wedge of substantially the same length as the lower portions of the sections and of a width less than the width of the rail head, said wedge having upper and lower surfaces spaced and shaped to correspond to the tapered space between the top of the rail head and lower surfaces of the upper portions of the mating sections whereby tightening of all of the bolt means will clamp the jaw surfaces on the side faces of the rail head and the wedge to the top of said rail head and striking the sections will tighten the sections on the wedge and rail throughout the length of said sections.
