Specification of Letters Patent.
Patented Oct. '5, 1915.
Application filed October 3, 1914. Serial No. 864,733.
To all whom it may concern:
Be it known that I, FRANK MULVEY, a citizen of the United States, and resident of Waupun, in the county of Dodge and State of WVisconsin, have invented certain new and useful Improvements in Railway- Brake-Setting Mechanism; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention consists in what is herein particularly set forth with reference to the accompanying drawings and pointed out in the claims of this specification, its object being to provide for automatic compulsory stop of air brake railway rolling-stock that would otherwise run through danger zones.
Figure 1 of the drawings is a perspective diagram illustrating my invention; Fig. 2, a diagram in elevation and sectionof a fragment of what is shown in Fig. 1, the section being indicated by line 2-2 in Fig. 3, which Fig. 3, is a diagram in plan and horizontal section of what is shown in Fig. 2, the section being indicated by' line 3-3 in said Fig. 2, and Fig. 4, a transverse sectional view indicated by line 44 in Fig. 3.
Referring by numerals to the drawings, 5 indicates a tripper having trunnions 6 by which it is pivotally mounted between ties of a railway-track, bearings 7 for the trunnions being shown in Figs. 2 and 3. An end of the tripper is shown connected by a linkrod 8 with an arm of an elbow-lever 9 having the other arm thereof in connection with a rod 10 parallel to the railway track. The rod connects arms of other elbow levers 11, 12, and the lever 11 is connected by a link 13 with an actuating lever 14 that may be located convenient to an operator in a signal tower, such a tower being indicated by dotted lines in Fig. 1. Extending transversely of the railway-track is a rod 1 5 conneeting the lever 12 and a T-lever 16 having the horizontal branches thereof connected by link-rods 17, 18, with crank-ends of semaphores 19, 20, respectively, and both semaphores are on the same pivot-rod 21, whereby when one semaphore is horizontal, the other is swung down adjacent to a side of said track, as is customary practice in railway signaling. The supports for the levers 9, 11, 12, 14, 16, and the pivot-rod 21 are omitted from the diagram showing in Fig. 1, but the operation of the semaphoremechanism will be readily understood, and
my invention is not limited to the pivotal tripper in connection with such mechanism.
When swung up to vertical position, the tripper 5 is in the path of a. buffer 22 pivotally suspended from a locomotive or other railway rolling-stock on the track aforesaid, the buffer being part of mechanism by which to operate a release-"alve of an air-brake system with which said rolling stock is equipped. Two buffers are shown, each in pivotal connection with a bracket 23 fast on an end of an angle-rod 24 slidable in guides 25, 25, belonging to said rolling-stock, and a spring 26 is interposed between the buffer and bracket, as shown in Figs. 2 and 4. The disposition of the angle-rod 24 is such that one or the other of the buffers is effective against the elevated tripper 5 regardless of which end of the rolling-stock is running in the direction of the arrow on the railwaytrack in Fig. 1. An arm 27 fast on the angle-rod 24 is shown provided at its outer end with a slot engaged by a lug 28 of a lever 28 fast on the stem 29 of the aforesaid release-valve. Hence when the tripper 5, in vertical position, is struck by a buffer 22, there is sliding movement of the rod 24 in its guides, and the arm 27 of said rod operates the valve-lever 28, the result being an automatic setting of the air-brakes of the rolling-stock. The rigid arm 28 of the rod 24 is between guides25, and these guides serve as stops to limit play of said rod in either direction, and a brake-setting operation of the valve-lever having been automatically accomplished, there is yield of the buffer against spring-resistance to pass the tripper.
If the trip-setting means is in connection with semaphore-mechanism, as herein shown, the semaphore for danger will be displayed when the tripper is vertical, and the semaphore for clear track will be displayed when said tripper is swung down out of the wav.
In matters of structural detail the mechanism above specified may be indefinitely varied without departure from my invention as herein claimed.
I claim:
1. A railway-track, rolling stock running on the track and provided with automatic brake-setting mechanism comprising an angle-rod slidable in guides, an arm rigid with the rod and connected to a brake'control device, and tripper-opposing opposite buifers carried by the rod, the tripper being on the track and provided with automatic brake-setting mechanism comprlslng an angle-rod slidable in guides, an arm rigid with the rod and connected to a brake-control device, and tripper-opposing buffers carried by the rod at its ends, the tripper be- 1 Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
justment in connection with a semaphore in and out of the way of one or the other of 15 the buffers.
In testimony that I claim the foregoing I have hereunto set'my hand at WVaupun in the county of Dodge and State of Vvisconsin in thepresence of two witnesses.
