  1. 1
    What is claimed is— A wire-stretcher comprising a frame including spaced side members and intermediate end blocks having perforations therein, a shaft journaled in the frame and extending at one no end beyond a side member, a drum mounted i upon the shaft and provided at one end with To all whom it may concern:Be it known that I, Charles R. McPherson, a citizen of the United States, residing at Monango, in the county of Dickey, State of 5 North Dakota, have invented certain new and useful Improvements in Wire-Stretchers;and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art co io which it appertains to make and use the same. This invention relates to wire-stretchers, and has for its object to provide a device of this nature which will be simple of construction and cheap of manufacture. 15 Other objects and advantages will be apparent from the following description, and it will be understood that modifications of the specific constructions shown may be made and any suitable materials may be used for the so various parts without departing from the spirit of the invention. In the drawings forming a portion of this specification, and in which like, numerals of reference indicate similar parts in the several 25 views, Figure 1 is a plan view of the stretcher in use and showing the clamps engaged with the ends of the rope. Fig. 2 is a section on line 2 2 of Fig. 1. Fig. 3 is a section on line 3 3 of. Fig. 1. 30 Referring now to the drawings, the present invention comprises a frame 5, consisting of spaced parallel side members 6 and 7, between the ends of which are secured blocks 8, having perforations 8' therein. The members 6 35 and 7 have bearing-openings 9 therethrough, in which are journaled the ends of a shaft 10. The ends of the shaft extend slightly beyond the side members, and in the end beyond the member 7 there is a perforation 11 for the re40 ception of a cotter-pin 12 to prevent disengagement of this end from the opening 9.. The opposite end of the shaft is provided with a head 13. A drum 14 is mounted upon the shaft 10, one end of which is provided with 45 ratchet-teeth 15 for engagement of a pawl 16, to be hereinafter described. The drum has a transversely-extending perforation 17 therethrough for the reception of a rope or cable 18, the ends of which pass through the per5° forations 8' of the blocks 8. Clamps 19 are engaged with the ends of the rope. Each clamp consists of a plate 20, having a perforation 21 therein at one end for the reception of the rope or cable and the opposite end of 5 i the clamp terminates in a hook 22. A flange 23 is formed upon one edge of the plate, the “ 810,795 ratchet-teeth, a rope engaged with the drum, a lug secured upon the inner face of one of the side members and having a socket therein, a pawl pivoted to the last-named side member 5 adjacent to the lug, said pawl having oppositely-extending fingers, one of said fingers lying normally in engagement with the ratchetteeth of the drum, a downwardly-extending projection formed upon the other of said io fingers, a helical spring disposed upon the projection, said projection and spring being dis posed in the socket of the lug to hold the firstnamed finger normally in engagement with the ratchet-teeth, and a double crank-arm engaged with the projecting portion of the shaft. 15 In testimony whereof I affix my signature in presence of two witnesses.
