JOSEPH KLANSNIC, or BLACK DIAMOND, WASHINGTON.

SAFETY-STOP Foa MINE-cans.

Patented Maf. 1s, 1919.

Application Ied January 31, 1918. Serial No. 214,618.

To all whom t may concern y Be it known that I,\J0sEPH KLANsNIo, a. citizen ofthe United States,l and resident of the town of Black Diamond, county of King, and State of Washington7 have invented certain new and useful Improvements in SafetyStops for Mine-Cars, of which thevfollowing is a specification.

' My invention Vrelatesto a safety stop attachment for mine cars and consists of certain improvements over a device of the same character shown in my previous PatentNo. 1,219,748', dated March 20, 1917;

The object of my present invention is to improve upon the construction of the car therein shown, and particularly along the line of providing means by which the parts may be locked'in the position assumed when the car body is raised, and also in the providing ofmechanisni whereby the swinging ofthe levers'upon which the'wheels are j ournaled, cannot take place in the opposite direction from that which is intended. Qther objects will be disclosed from a study of the specic-ati'on in this case and the feal tures which Ik claim to be novel will be de.-

dropping down upon the rails when the fined by the claims terminating said specification. i

In the accompanying Vdrawings I have shown my device embodied in the form of construction which I now prefer.

Figure 1 is a side elevation of a-car showing a Vportion of one side andthe central partitions broken away, in order to better show the operating mechanisms.

Fig. Qais av plan view .of my car showing` aportion of the body broken away in order to better showthe mechanism.

F'g. 3 is an end elevation of a car having myimprovement thereon, a portion of one end of the body being broken away. to show parts behind the same. l f Y f In `the construction of cars shown in my previous patent above referredto, no provision `was madeto prevent the car from heavy strain, due to hauling upan incline, isre'moved. It would, therefore, be impos-V sible to operate said cars except on'inclines where the backward strain upon the haulage body of the, car raised.A Should the car, as shown in said patent, run upon a level stretch it would immediately drop the car body upon the track- Y Furthermore, no provision was made to in said patent, are provided with spurs-or dogs 20 which project downward a sufficient distance to make certainA their engagement with 'the ties or with other parts of the track structurein such manner as to stop the car and hold it, even if it be upon a considerable grade.

In some cases a` timber is employed eX- tenoling lengthwise of the track.l which timber would beplaced so as to be engaged by the spurs 20. These spurs are preferably secured to a plate 21 which is secured to the under side of the beam 2. They are preferably made detachable so they may be renewed in case one becomes broken Vor pulled out.

Car aXles 3 are journaled upon the car body in accordance with the construction shown in saidfpatent. Lever arms 4 are secured to these axles or shafts 3 at opposite ends and the track wheels 9 are journaled upon the swinging ends of these levers. Lever arms 5 are also secured to these shafts` one upon each shaft.. These latter arms, instead of being placed at the outside of the car body, one at each side thereof, as was done in said patent, are placed at the center, one for each shaft 3.

Each of the'aXles is provided with vitsl lever 5, and these are connected by a link 50, which link is also provided with means whereby the haulage connection may be made therewith. A shield or casing 11, shaped to accommodate the wheels when the car body drops down, is provided over each wheel, this being shaped so as to accommodate the wheels and the lever arms` upon which the wheels are mounted.

The mainhaulage connection is through a member which is. connected with a draft bar 6 secured to the frame of the car. The cable by which the car is pulled, is connected with the eye 62 to which the member 60 is secured and to which also is secured a like vmember 61, this extending to'V a connection with the forward end of the link 50. i

To accommodate the levers 5, and the parts connected therewith, asV V50 and 61, a narrow compartment running lengthwise the car is formed by the twc walls '12. 'This compartment may extend throughout the length of the car and ordinarily would do so, but might be out short at the end oppo-v sitegthe haulage connection. This compartment should` preferably be covered on top and be open at the end where the cable 61 enters.Y` 1

It is evident that the strain upon the haulage cable communicated through the connecting member 61, will act upon the longer lever 5, to swing the shorter lever 4, upon which the wheels are mounted, downward vand backward, thus raising and maintaining the c-ar body in elevated position so long as this strain is continued. However,

. when this strain is released, the relative ansections.

gular` positions of the lever arms 4, as referred to a perpendicular, will cause the car body to dropl backward.

The strain communica-ted through this connecting member 61 is found to not be suiiicient to maintain the car body raised when the car is on a level track, or a track with a slight grade. It is, however, desirable to be able to operate these cars upon such level I,' therefore, provide a locking link 8, which is pivoted to a bar 80 secured to one end of the car body, which link- 8 is provided, at its freely swinging end, with a hook vwhich engages the forward end of'the link 50, or .with any other suitable member which is connected withthe levers 5. When so engaged, the car body willsbemaintained inA raised position, even if the strain is entirely vremoved from the connecting mem- Asherein shown, I have provided a recess at 70 inthe outer vsides of the longitudinal beams 2 and in the metal plate 21, which recess accommodates the lever arms 4 upon which the wheels are journaled. The shoulder 7 at the rear end of this recess, is so placed that -it will engage the lever arm 4 and prevent it from swinging backward'v .farther than is desired.

Thisstop may, of course, be provided by.

'i i other means, but the one describedy I have found convenientand satisfactory. By the use of a stoplocated in this manner itis impossible fory the leversto swing too far in Y the "backward'direction Should ythe wheel carrying levers swing forward tocsuch point that the car body will settle uponthe trackway, .the carbody l can be automatically raised by pulling upon the haulage lines,Y as

y it could not if theleversA were toY swing Y' i backward or` in the opposite direction.
