RAIL STOP Filed May 2, 1928 INVENTOR THOMAS SMART ATTORNEYS Patented Aug. 27,1929.

BAIL Application filed ma 2,

My invention relates to improvements in rail stops which are particularly adapted for use in dry kilns of lumber mills and other like situations where the rails are usually laid on a slight incline, so that the cars may travel by gravity from one point to another. The object of the invention is to provide a stop which may be readily collapsed and removed from the rail andas quickly reassembled in position to prevent the passage of further rolling stock; e

Theinvention consistsessentially of a pair of arms pivotally connected to one rall of the track'of which one is provided with a stop capable of being disposed transversely of said track and means for releasably connecting the free ends of said arms together, as will be more fully described in the following specification, and shown in the accompanying drawings in which Fig. i 1 is an elevation of theinvention fitted to a rail.

Fig. 2 is a plan view.

In the drawings like characters of reference indicate corresponding parts n each figure. I r i I The numeral 1 indicates one of the rails of a tramway trackcalong which a car 2 is;

adapted to travel. The car 2 such as is used in lumber kilns and the like, is provided with a low built frame 3 having transverse members 4 at opposite ends. The frame 3 is mounted upon small flanged wheels 5. .An eye bolt 6 extends freely throughthe web of the rail 1 which is provided with a shoulder 7 adjacent one end so as to project the eye 8 of the bolt a suitable distance beyond the bulb of the rail 1. The'opposite end of the bolt 6 is fitted with a distance collar 9 and a pair of lock nuts 10.

Hingedly connected to the eye 8 of the bolt 6 as at 11 is an upturned L-shaped arm 12 having a vertical member 13 from which a transverse portion forming anpabutment 14 extends, the free end of the abutment being outwardly turned as at 15 in a plane parallel to the upturned portion 13. Aligned,

apertures 16 are formed in the portions 13 and 15, the purpose of which will, hereinafter appear. Pivotally mounted upon the bolt; 6 between the distance collar 9 and the lock nuts 10 is a further L shaped arm 17 having an upturned end portion 18 which is aper tured as at 19 to register with the apertures 16. A withdrawable pin 20 is normally car:

ried in the apertures 16 and 19 for the purs'roii 1928. Serial No. 274,620,

p supportinglthe arm 17in a position parallel to the arm 12 and for' anchoring the end portiton 15 of the abutment back to the bolt 6 through the arm 17. This pin is preferably provided with a chain 21 secured at one end to the arm 12. I

Having thus described the several parts of my invention I will now briefly explain its use.

The rail stop is set up in position as shown 3 with the abutment 14 lying transversely across the rail '1 and the pin 20 inserted 1 through the apertures 16 and 19 so that all the several parts are firmly connected together to withstand the shock of a'car being brought to rest with its transverse end memher 4 in contact with the abutment 14. It 7 will be readily assumed that where the track 1 I issetlon an inclineand a loaded car is held against movement by the rail stop that an appreciablestrain would be imposed upon 1 l the stop, this strain is mainly appliedthrough the arm 12'to one end of the eye bolt 6 and through the end of the pin 20 and the arm 17 to the other end, therefore by simply snatching the pin 20 by the chain or by driv- .ing itwith a light hammer blow, it is withdrawn from the aperture 19 in the upturned end 18 of the arm 17 which falls by gravity below the top of the rail as shown in dotted line in Figure 1, and the arm '12 with its abutment 14 is swung clear of the car 2, see position indicated by dotted line in Figure 2, and the car is freeto move further downthe inclined track as desired. It will be apparent that as soon as the abutment 14 is moved beyond the edge of the rail, the arm 12 is permitted todrop also, so as to be free of any overhanging projections of the car which might otherwise obstruct the passage ofthe car along the track.

What I claim as my invention is: 1. The combination with a track rail, of astop comprising a pair of L-shaped arms each having a horizontal member pivotally connected at one end to'the rail and an upturned member at the other, and means for releasably connecting the upturned members together across the rail. 1

2. The combination with a track rail, of a stop comprising a pair of L-shaped arms each having'a horizontal member pivotally connected at one, end tothe rail and an upturned member at'the other, and a pin for releasably connecting the upturned members together across the rail. i 1

3. The combination with a track rail, of a stop comprising a pair of L-shaped arms each having a horizontal member pivotally connected at one end to the rail and an upturned member at the other, an abutment carried by one of the upturned members, and

means for releasably connecting said up-- 7 turned members together with the abutment interposed therebetween.

, 4. The combination with a track rail, of

, a stop comprising a pair of L.-shaped arm's each having a horizontal member pivotally Dated at Vancouver B. 01, this 23rd day of April, 1928. V v o {THOMAS SMARTL
