TENSION DEvlcE.
SPECIFICATION forming part of Letters Patent No. 733,936, dated July 21, 1903. Application filed September 25, 1902. Serial No. 12111781.. (No model.)
To all whom i may concern:
Be it known that I, J AMES BARRETT, a citizen of the United States, and a resident of Tombstone, in the county of Cochise and Territory of Arizona, haveinvented a new and Improved Tension Device, of which the following is a full, clear, and exact description.
This invention relates to a device for operating bell-cords and all other flexible connections to whistles, trip devices, and like instruments where a signal or impulse isto be transmitted.
It comprises certain novel features of construction, which will be fully described hereinafter. l
This specification is an exact description of one example of my invention, while the claims define the actual scope thereof.
Reference is to be had tothe accompanying drawings, forming a part of this specification,-
in which similar characters of reference indicate corresponding parts in both views.
Figure l is an exterior view of the invention, and Fig. 2 is a longitudinal section thereof.
The device comprises a cylindrical or tubular casing a, at the ends of which are respectively arranged screw-caps t) and c, each cap being formed with an inwardly-projecting flange b' and c'. These caps b and c inclose collars, (designated d and c, respectively,) such collars being held tightly between the flanges b' and c and the respectively adjacent ends of the tubular body a.
f indicates the rod, which-is run through the collars d and e and which has its upper portion formed with a shoulder f', against which bears a washer g', this Washer being engaged by the adjacent end of an expansive spiral spring g, which is located in the tubular body a and bears at its other end against the collar d. The rod f is projected upward beyond the collar e and has its upper end formed with an eye f2, to which is connected a cord h, such cord passing to the bell, signal, or other device to be operated. The lower extremity of the rod f is threaded and has a shackle t' screwed thereon, and with 5o this shackle is engaged the pull-cord lo.
`parts to their normal position.
When the cord lois drawn down, assuming that the body a be held stationary, the rodf will be moved with the cord oand the spring g will be compressed. This also carries down the cord h. When the cord k is released, the spring g asserts itself and returns the After the proper adjustment has been secured the spring g keeps the cord h at proper tension and insures the quick and certain action thereof. It also promptly returns the pullc'ord k and enables a number of rapidly successive pulls to be made, owing to the prompt return of the pull-cord by the action of the spring.
Various changes in the form and details of my invention may be resorted to at will without departing from the spirit of my invention. Hence I consider myself entitled to all forms ot' the invention as may lie-within the intent of my claims.
Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination of a tubular body, a cap fastened to each end thereof, said caps having inwardly-projecting flanges at their outer ends, collars inclosed by the caps and engaged by the flanges thereof to hold the collars iu place, a rod projected loosely through the collars and adapted to have cords connected with its ends, and a spring contained inV the casing and pressing the rod, for the purpose specified.
