lvlINTfCAR-TALLYING DEVCE.

To all' whom it' may concern.

Be it known that I, JOHN Ross, a citizen of the United States, residing at Terry, in the county olf Lawrence and State of South Dakota, have invented certain new andusemful improvements in Mine-Car-Tallying Devices, of which the following is a speciiication.

This invention relates to tallying devices for mine cars, and the novelty resides in certain speciiic features of construction hereinafter fully described. and claimed, and illustrated in the accompanying drawings, in which* Figure l is a side elevation, showing the movable track members in normal elevated position in tull lines and depressed as when under the weight ot a loaded car in dotted lines, and 2 is a transverse section subi stantially on the broken line QMQ of Fig. l,

the movable rail members however being in their depressed position.

'lll'iroughout the following description and on the sever l. igures ot the drawings similar parts are referred to by like reference characters.

At l0 is indicated the main track-way over which the cars are adapted to be run in either direction, but it being understood that loaded cars are to be operated in the direction or" the arrow o. Movable track members ll are hinged at l2 to the main track in such a manner that the movable members may be normally elevated at the end 1l opposite the hinge l2, such elevation being maintained normally by virtue oit' strong coil springs 13. The springs may be mounted and maintained in position by any suitable means, but preferably they are contained in boxes 14: with movable abutments 15 so that the tension or force ot the springs may be varied in accordance with the particular service to be performed, such adjustment being effected by suitable means, such as screws 1G. The ends l1 oit the movable track members may it found necessary be connected to the main track on the opposite side ot the device by means of auxiliary movable members 17 so that an empty car may pass freely over the device in the reverse direction if desired.

At lS'is shown a'conventional form oit indicator dial, the mechanism oi which is adapted to be operated step by step by means of a r0d'19 extending from the indi- Specication of Letters Patent.

cator down through a supporting post or stand 20. The indicator dial 18 may be located at any convenient point or place and may be housed from outside interference trom obstacles along the track-way. Connected near the ends ll of the movable track members is a transverse bar 2l, movable bodily up and down with said track members. A lever 22 is pivoted at 23 upon any suitable stationary support, such as indicated at 2li, and one end of said lever is connected at 22 to the aforesaid bar 2l and the other end is connected to the rod 19 at 22. It is contemplated that this device is tor recording` the number of loaded cars of a certain minimum weight as they pass along the track. The springs 13 are to be so constructed and adjusted as to resist downward movement of the track members 11 except when a ear ot the required weight is recived thereupon. lNhen a sufficiently loaded car is received the track members will be depressed against the tension of the springs, causing the bar 2l to be forced downward and the rod 19 upward, and thereby registering one car in a manner well understood in this art.

An important feature oiI this invention resides in a device indicated at Q4, which consists ot' a stationary rigid cam or stop, the function ot which is two-told. First, the stop Q4: will prevent the reverse movement of a loaded car whereby it might be registered a second time undesirably, and secondly, the peculiar form ot the cam member is suchthat it will insure the proper registering operation of a passing loaded car. its indicated the normal position ot the track members ll is such that an empty or a lightly loaded car may pass along in either direction thereover without the member 24e being` engaged, but when a car to be registered comes along its weight will be sutlicient to cause the axles thereof to strike or roll upon the point or points 24', it being understood that sutlicient torce or power must be applied to the car to cause the same to ride over said point or points. lVhen the' car axles pass such points the effect will be for the car to partake of a slight drop, giving a decided impulse downward to the track members 1l. The inclines 21k* leading to the points 24 should ot course be sutlieiently long to prevent the car from being stopped in its operation thereover.

Having` thus described the best `form of the invention now known to me, but without desiring` to be limited to the exact details ot construction, except as may be required. b v tlie state of tlie art, what claim is:

l. In a tallyin;v device for cars, the combination of a track embodying mo 'able members, means for normally sustaining said members in an elevated position witli respect to the main track.` an indicator, means connecting` the indicator and movable track members for operation of tlie indicator thereby when the track members are depressed, and means associated with the movable track members to raise. a car theret'rom and drop said car bodily thereon as it passes over said members.

2. In a tallying device, the combination of a main track, movable track members associated therewith, means normally maintainini; said movable members out ot' alinement with tlie main track, an indicator' dial, connections between said dial and the movable track members whereby when the latter are depressed tlie indicator will be operated, and a rigid statiomiry stop device located between the movable track members liaviugl` a pair of shoulders ind slow inclines leading' rearwardly therefrom to receive the car axles, t'or tbe purposes set` tortli.
