JAMES B. SUFFERN, OF HILLBURN, NEW YORK.

SWITCH-STAN D.

SPECIFICATION forming part of Letters Patent No. 516,241, dated March 13, 1894.

Application filed June 21,1893. Serial No. 478,398. (No model.)

To all whom t may concern:

Be it known that I, JAMESI B. SUFFERN, a resldent of Hillburn, in the county of Rockland and State of New York,have invented certam new and useful Improvements in Switch- Stands; and I do hereby declare the following to be a full, clear, and exact description ofthe inventlon, such as will enable others skilled 1n the art to which it appertains to make and use the same.

My invention relates to an improvement in switch stands-the object of the invention being to produce a switch stand which can be readily operated, either automatically or manually, and the operation of which shall be easy, sure and effective.

A further object is to so construct a switch stand capable of being operated either automatically or manually, that the friction and wear between the parts will be reduced to a minimum.

A further object is to produce a switch stand capable of being operated automatically and manually, which shall be simple in construction, cheap to manufacture and effectual in the performance of its functions.

With these objects in view thev invention consists in certain novel features of construction and combinations and arrangements of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings: Figure l is a plan View, partlyin section. Fig. 2 is a side view, partly in section. Fig. 3 is a cross sectional view. Figs. 4, 5 and 6 are detail v1ews.

A represents a base, from which a standard or plate B projects upwardly and is supported by means of brackets B. The upright or plate B is made with a circular recess a for the reception of an oscillatory hub C. The standard or plate B is made with a circular opening b for the reception of an oscillatory hub or collar D projecting from a disk D which bears against the outer face of said standard B. Two arms E, E, are adapted to pass loosely through angular perforations c in the disk D' and collar D and are connected at their rear ends by means of a cross bar d. The arms E are preferably made of spring metal and enter a rectangular opening e in the block F,'and said arms are provided in proximity to their ends with recesses c adapted to receive flanges e2 projecting inwardly from the ends of said elongated slot or opening e. The standard B is made with a'reotangular recess or seat f for the block F, for a purpose which will hereinafter belexplained. The inner face of the hub C is also provided with a rectangular recess or seat f for the accommodation of the block F and in proximity to the ends of said recess or seat f, angular perforations g are `made in the hub C for the passage of arms F carried by the block F,-said arms F being provided in their outer faces with curved recesses f2. The angular perforations g communicate with an elongated slot or recess g in the outer face of the hub C, said slot or recess gbeing preferably made with curved ends g2, which, with the curved sockets or recesses f2 in the arms F', produce circular sockets g3 when said arms are projected. A shaft or axle Gr projects from the hub C, through the block F and hub or collar D, said axle or shaft being made angular as at g4 where it passes through the block F and round Where it passes through the collar D, the outer end of said axle or shaft being made angular and adapted to enter a recess in the cross bar d and connected with said cross barby means of apin h, passing through an elongated slot h in an axle or shaft. The pin h also serves to pivotally connect to the cross bar d, the free, bifurcated, end of a lever H, said lever being pivotally connected at a point between its ends to an arm t' projecting from the disk D. The lever H is so bent as to approach the standard B, to which it will be normally secured by means of a pad-lock fi.

Bolted to the base A, is a hood I, whichis provided with a slot or opening j for the accommodation and guidance of a moving rod J, to the free end of which the switch rod J is connected. The moving Vrod .I extends inwardly, and is providedwith a pin 7'2 adapted to enter the elongated slot or recess g in the face of the hub O. A casing or box K is 1ocated ou the base A, Within which a spring K is inserted, for which spring, a suitable follower K2 and follower rod K3 are provided. A toggle or link K4 is connected at ,one end with the follower K2 and at the other end with the moving rod J, preferably atl a point diametrically opposite the pin jz. NVhen the parts are in their normal positions and the lever I-I locked, the block F will be in the recess f and the ends of the arms F will be ilush with the base of the slot or recess g' in the hub C. With the parts in these positions, should the switch be operated automatically by means of any suitable devices, the pin 7'2 will move freely from one end to the other of the recess g and thus permit the switch to be readily thrown.

Should it be desired to operate the switch by hand, the lever H will be first unlocked, and then turned on its fulcrum to force the blockF forward and project the arms F into the recess g thus producing the sockets g3, one of which will inclose the pin 'i2 on the movlng rod. The lever H will now be thrown to the other side of the stand, thus oscillating the hub C so as to reverse the position of the end s of the recess g', whereby the moving rod J will be thrown to operate the switch. The leyer H will then be turned on its fulcrum to wlthdraw the arms F from the recess g and the lever locked in the manner above explained, but at the opposite side of the stand. The stand is now again set to permit the switch to be operated automatically.

My improvement-s are very simple in construction, easy to operate, cheap to manufacture and effectual in the performance of their functions.

Slight changes might be made in the details,`

of construction of my invention without departlng from the spirit thereof or limiting its scope and hence I do not wish to limit myself to the precise construction and arrangement of parts herein set forth, but,

I-Iaving fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a switch stand, the combination with a standard, of a hub supported thereby and havlng an elongated recess, a moving bar, a pin projecting from said moving bar and adapted to enter said recess, and arms for lookin g said pin in the recess, when the switch 1s to be' operated manually, substantially as set forth.

2. In a switch stand, the combination with a standard having circular recess therein, of a hub supported by said standard and adapted to oscillate in said recess, said hub having an elongated recess in its outer face, a moving rod adapted to be connected with a switch rod, a pin carried by said moving rod and adapted to enter said elongated recess, and arms for producing sockets at the ends of said elongated recess, when the switch is to be operated by hand, substantially as set forth.

3. In a switch stand, the combination with a standard, of a hub supported thereby and having an elongated recess in its outer face and an angular recess in its inner face, a moving rod adapted to be connected with the switch rod, a block adapted to enter said angular recess, arms projecting from said block through the hub and adapted toenter said elongated recess at points near the ends thereof whereby to produce a socket for the reception of a pin when the stand is to be operated by hand, and means for operating said block and arms, substantially as and for the purpose set forth.

4. In a switch stand7 the combination withy a standard having an angular recess therein, of a hub having an elongated recess in one face and an angular recess in the other face, a block adapted to enter said angular recesses and remain normally in the angular recess in the standard, arms projecting from said block through the hub and adapted to enter the elongated slot near its ends, when moved forward, and means for operating said block, substantially as set forth.
