Description

' A. B. DILL.
WIRE STRETCHER. APPL|CATION FILED MAY 27, 1914'.
A TTOB/VEVS THE NORRIS PETERS ca. FHOTO-LITHO.. WASHINGTON. D. C.
AB 13. DILL, OF LAKIN, KANSAS.
WIBE-STRETCHER.
Specification of Letters Patent.
Application filed. May 27, 1914. Serial No. 841,222.
To all whom it may concern:
Be it known that 1, AB B. DILL, a citizen of the United States, residing at Lakin, in the county of Kearny and State of Kansas, have invented an Improvement in Wire- Stretchers, of which the following is a specification.
My present invention relates to wire stretchers, and my object is to provide a device of this character improved with respect to strength, simplicity and effectiveness for the purpose of which it is intended, these objects residing for the most part in the detail construction of the device to be now described with reference to the accompanying drawings, forming a part of this specification, and in which:
Figure 1 is a side elevation, the ends of the pull-bar being broken away. Fig. 2 is a vertical transverse section taken through the pull-bar and showing the carrier and the operating lever in end elevation. Fig. 3 is a vertical transverse section taken through the device substantially on the line 33 of Fig. 1; and Fig. 4 is a detail perspective view of one of the working dogs removed.
Referring now to the figures my improved device includes a longitudinally movable pull-bar A having rows of notches along its upper and lower edges, and the notches of which upper and lower rows, as indicated respectively at a and a are staggered with respect to one another. This pull-bar works through a carrier B having a tapered forward portion B and consisting of side plates 6, between the forward portions of which are secured upper and lower body pieces I), as best shown in Fig. 3. The side plates 1) are connected in spaced relation by means of the body pieces mentioned and by the use of fastening members 12 in the form of screws, rivets or the like, and between their rear portions is extended a vertical operating lever C, having an enlargement G adjacent its lower end as best seen in Fig. 2, which enlargement is provided with laterally projecting trunnions c.
The side plates 7) of the carrier B may be provided with apertures 6 adjacent their rear ends to receive ropes, cables, chains and the like for attaching the carrier to a suit-j able support, for instance a fence post, and
the side plates are further provided with intermediate openings through which the trunnions a of the operating lever extend.
The enlargement C has a slotted opening a through which the pull-bar A also extends and above and below this enlargement the lever is provided with laterally projecting pivot bolts 0 upon which are pivoted the rear ends of similar working dogs D, one of which is shown in detail in Fig. 4. These dogs work against the upper and lower edges of the pull-bar A and are provided with forward hooked ends (Z for engagement with the pull-bar notches a and a, under tension of springs E, the forward ends of which bear against the dogs D and the rear ends of which are secured to the carrier B.
Thus with the carrier B attached to a suitable support, for instance a fence post as above mentioned, and with the forward end of the pull-bar A attached by any suitable means to the fence wire to be stretched, the upper handle end of the operating lever C is moved forwardly and rearwardly in order to draw the pull-bar rearwardlv. the upper and lower dogs D alternately taking hold of the pull-bar and by engagement within the staggered notches thereof.
A wire stretcher of this character is light and compact, may be readily set up and taken down before and after the stretching operation, and will be durable and effective in use for the purpose for which it is intended.
I claim:
A wire stretcher comprising a pull-bar having staggered rows of notches in its upper and lower edges, a carrier comprising side plates tapered at their forward ends and body pieces disposed between the side plates, said side plates and said body pieces being spaced apart to receive the pull-bar therethrough in movable guided relation, a lever extending vertically between the rear portions of the side plates and provided with an enlargement adjacent its lower end having a vertically slotted opening through which the pull-bar also extends, said lever enlargement having laterally projecting trunnions and said side plates having apertures in which the trunnions are journalecl, laterally projecting pivot bolts ex- Patented Apr. 6, 1915. V
tending through the lever above and below hold the latter in engagement with the pullits said enlargement, operating dogs jourbar at all times. naled at their rear ends upon the said pivot bolts and having forward hooked ends for AB DILL' engagement Within the notches of the pull- Vitnesses: bar, and springs secured to the carrier and HENRY OoHs, bearing upon the said operating dogs to A. R. HETZER.
Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. C.
