CHARLES R. WOODWARD, OF CAMPBELL, NEW YORK.
- MOVI EMENT TRANSM ITTING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 620,819, dated March 7, 1899.
Application filed July 11 1898. Serial No. 685,664. (No model.)
T 00% whom it may concern:
Be it known that I, CHARLES R. W001)- WARD, of Campbell, in the county of Steuben and State of New York, have invented a new and Improved Movement-Transmitting Apparatus, of which the following is a full, clear, and exact description.
This invention relates to apparatus adapted particularly for use on rail and other tram ways by which movement may be transmitted to a distant point from contact with the rolling-stock, the invention being particularly adapted to the operation of railway gates, switches, and signals.
This specification is a disclosure of one form of the invention, while the claims define the actual scope of the invention.
Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a plan view of the positivelyacting portion of the invention, parts having been broken away in said view. Fig. 2 is a longitudinal section of the element illustrated in Fig. 1. Fig. 3 is a longitudinal section of the releasing devices, and Fig. 4 is a similar view with the parts in different positions.
The positively-acting part of the invention has a frame 5, that is adapted to be embedded in the roadway, so that its upper surface will lie approximately flush therewith. On this upper surface is formed a trackway 6, at each side of which is a gradually rising and falling inclined rib 7. Sliding in the trackway 6 is an elongated block 8, carrying at its outer end a shoulder 9. A tappet or detent attached to the rolling-stock as it passes over the frame will engage with the shoulder 9 and slide the block 8 leftward in Figs. 1 and 2 until the tappet engages with the inclined ribs 7, whereupon the tappet will be raised automatically to disengage the shoulder 9, and thus release the shoulder and the block thereon.
Journaled in the frame 5, beneath the upper side thereof, is a revoluble shaft 10, to which are fixed three pulleys, designated, respec tively, 11, 12, and 14. Around the pulley 12 is wound a cable 15, which has at its outer end a retractile spiral spring 16, in turn connected with the short section of a cable 17,
which in its turn is attached to the block 8. As the block 8 is moved leftward or away from the shaft the connections 17, 16, and 15 are drawn upon to turn the shaft 10, with its several pulleys, in the direction of the ar row indicated in Fig. 2.
The pulley 14 is provided with a cable 18, wound on the periphery thereof and passed downward through a loosely-sustained cap 19 and into a cylindrical holder 20. This holder contains a series of superimposed weights 21, (see dotted lines in Fig. 2,) which weights are attached to the cable 18. Pivotally mounted on a partition or wall 22 in the frame or casing 5 is a brake-bar 23, carrying a shoe 24, (see dotted lines in Fig. 2,) which is adapted to engage with the periphery of the pulley 14. The normal position of the parts is that shown in Figs. 1 and 2. When the block 8 is thrown leftward, the shaft 10, with its pulleys, is turned in the direction of the arrow and the weights 21 are drawn up into the top of the holder 20, so as to be engaged with the cap 19. This serves to lift the cap, which in turn throws up the brake-bar 23 and binds the shoe 24 against the pulley 14, and thus it stops the revolution of the parts 10, 11, 12, and 14, such stoppage being timedto occur simultaneously with the release of the lug 9 by the tappet of the rolling-stock.
Movement of the shaft 10 is transmitted to the other section of the apparatus through the medium of a cable 25, Wound on the periphery of the pulley l1 and attached to rodsections 26, the tension of which may be regulated bya turnbuckle 27. The leftward rodsection 26 is connected at its outer end with a section of cable 28. (See Figs. 2, 3, and 4.) The cable 28 passes into a frame or casing 29 containing a locking-bar 30, provided with a notch 31 and mounted to slide in a channelbar 32, having a shouldered portion 33, adapted to enter the notch 31, as indicated by dotted lines in Fig. 3, thus locking the bar in the position shown by said dotted lines. The
channel-bar 32 is pivoted on a pin 34 and pressed by a spring 35, so as to assume normally the position shown in Fig. 3. The left hand end of the locking-bar 30 has a cable 36 attached thereto, which cable is wound over a pulley 37, attached to a revolubly-mounted shaft 38, carried in the frame or casing 29.
The shaft 38 also carries a pulley 39, over the locking-bar 30 and to en gage,respectively,
at the sides of the channel-bar 32. The detent or tappet of the rolling-stock (for representation of which see element 44 in Figs. 3 and 4) rolling along the top of the frame or casing 29 will engage with the dog 40 and throw the same down, as indicated in Fig. 4, which, through the medium of the cheekpieces 43, presses down the channel-bar 32 and causes the shouldered portion 33 thereof to disengage from the walls of the notch 31, thus releasing the locking-bar 30 and permitting the same' to draw rearward in Figs. 3 and 4 by the action of the weights 21, transmitted through the parts and 26 and the shafts and pulleys connected therewith.
, In the operation of the invention the normal position of the parts is that shown in Figs. 2 and The tappet of the rolling-stock passing over the casing or frame 5 will push the block 8 leftward and raise the weights 21. This action will result in the slacking of the connections 25 and 26, and will thus permit the weighted cable 40 to turn the elements 37, 38, and 39 in the direction of the arrows shown in Figs. 3 and 4, and thus draw the locking-bar 30 into the position shown in dotted lines in Fig. 3 and full lines in Fig. 4. The spring 35 will now push the channel-bar upward to engage the shouldered portion 33 with, the notch 31. This will hold the lockingbar 30 and will also hold the weights 20 raised Simultaneously with these actions the brakebar 23, influenced by the cap 19, will be engaged with the sheave or pulley 14, and thus assist the several elements of the apparatus. WVhen the rolling-stock passes along the track and approaches the frame or casing 29, the detent or tappet will press down the dog 41 and release the bar 30. This permits the weights 21 (which weights considerably preponderate the force of the weight on the cable 40) to return the bar 30 to the position shown in Fig. 3 and also to rotate the parts 37, 38, and 39 in the direction reverse to that indicated by the arrows in Figs. 3 and 4.
The uses to which my invention is put will be obvious to persons skilled in the art, it being understood by them that movement thrown down the weights are permitted to act to preponderate the weight on the cable 40 and to throw the shaft 38 in the opposite direction, which, for example, may open the switch. The casings 5 and 29 are of course arranged along the track distant from each other.
Various changes in the size, relative proportion of parts, and the minor details of my invention may be resorted to without departing from the spirit and scope of the invention. Hence I consider myself entitled to all such changes as come within the scope of my claims.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of a pulley, a rope passing over the pulley, a member in connection with and lifted by the rope, and a brake bar adapted to be engaged by said member whereby to be moved to engage the pulley, substantially as described.
2. The combination of a pulley, a rope passing over the pulley, a tubular holder through which the rope extends, a Weight attached to the rope and located within the holder, a cap loosely mounted on the tube, the c ap being lifted by the upward movement of the weight, and a brake-bar engaged by the cap and moved into engagement with the pulley, substantially as described.
3. The combination ofalocking-bar, a channel-bar pivotally mounted adjacent to the locking-bar and capable of engagement therewith, and a releasing-dog mounted above the channel-bar and capable of moving to disengage the channel-bar, substantially as described.
4.
