Application filed June 1, 1911. Serial No. 630,564.

To all whom it may concern:

Be it known that 1, JAMES H. W. J ONES, a citizen of the United States, residing at Corydon, in the county of Henderson and State of Kentucky, have invented certain new and useful Improvements in Wire- Stretchers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to improvements in wire stretchers.

One object of the invention is to provide a stretching device adapted to be employed for the purpose of stretching wire, wire fences and the like and which may also be employed for pulling stumps or lifting heavy loads.

Another object is to provide a stretching device of this character having an improved construction and arrangement of operating device whereby the stretching or lifting operations may be easily accomplished. I

In the accompanying drawings, Figure 1 is a side view of my improved stretcher showing the parts in position for stretching a wire fence. Fig. 2 is a top plan view. Fig. 3 is a vertical cross section on the line 3-3 of Fig. 1. Fig. 4 is a similar view on the line 44 of Fig. 1. Fig. 5 is a side view of the stretcher arranged for pulling stumps. Fig. 6 is a detail vertical sectional view of the rear end of the frame on the line of the operating screw, showing the threaded engagement of the latter with the standard.

Referring more particularly to the drawings, 1 denotes a supporting frame comprising a pair of front supporting standards -2 and a single rear supporting standard 3, said standards being secured at their lower ends to suitable base plates 4. The upper ends of the standards 2 are connected together by a cross bar 5. To the upper end of the standard 3 and cross bar 5 are connected the opposite ends of an upper guide track 6 while to the lower end of the standard 3 and the front base plate 4 are secured the opposite ends of a lower guide track 7, said tracks 6 and 7 being arranged one above the other in the same vertical plane. The tracks 6 and 7 are securely braced to the standards by brace bars 8 whereby they are rigidly held in position on the frame. Arranged on the opposite sides of the frame, midway between the upper and lower tracks 6 and 7,

is a pair of guiding and supporting tracks 9 which are connected at their forward ends to the front standards 2 and at their rear ends to a horizontally disposed supporting plate 10, which is secured to the rear standard 3 and projects laterally from the opposite sides thereof as shown. The tracks 9, are braced and securely held in position on the frame, by inclined brace bars 11 which are secured thereto and to the standards and base plates of the frame as shown.

Slidably engaged with the tracks of the frame is a stretching carriage 12 comprising a vertically disposed supporting plate 13 having secured to its rear side outwardly extending inclined bars 14, the outer ends of which are secured to the plate 13 by short braces 15, the forward ends of which are engaged with sockets 16 arranged on the rear side of the supporting plate as shown. Secured at its opposite ends to the rear sides of the bar 14 is a screw guiding bar 17, said bar being spaced a suitable distance from the plate 13 and disposed in parallel relation thereto. On the upper and lower ends of the plate 13 are revolubly mounted supporting wheels 18 while on the adjacent outer ends of the inclined bars 14 are revolubly mounted guiding wheels 19. The wheels 18 and 19 onthe upper and lower ends of the plates 13 and bars 14 are adapted to engage and travel on the upper and lower track bars 6 and 7.

, Secured to the plate 13, midway between its upper and lower ends is a transversely disposed wheel supporting plate 20, the opposite ends of which project a suitable distance beyond the opposite sides of the carriage and on said ends are revolubly mounted side supporting and guiding wheels 21 which are adapted to engage and travel on the tracks 9 on the frame. The guiding and supporting wheels 18, 19 and 21 are all preferably in the form of grooved wheels and the tracks are suitably shaped to receive said grooved wheels. In the standard 3 and track supporting plate 10 is formed an opening and through said standard and over said opening is arranged a carriage operating nut or plate 22, having a threaded passage through which is adapted to work a threaded carriage adjusting screw 23 the inner end of which has a swiveled connection with a suitable connecting plate 24 arranged on the carriage supporting plate 13 as shown. The screw shaft 23 projects through the guiding opening in the bar 17 and on the outer end of said screw shaft is fixedly mounted a crank wheel 25 provided with a crank handle 26 whereby the screw is revolved in one direction or the other, thereby moving the carriage back and forth on its supporting jacks for the purpose of stretching the wire or fence with which the carriage is engaged. The wheel may also be provided with sockets 25 to receive radially projecting operating bars 25 for turning the wheel when doing heavy work. I Secured to the carriage supporting plate 13 is a pair of inwardly projecting clamping and supporting arms 27 which are suitably braced and held in position by inclined brace bars 28 which are arranged as shown and have their ends preferably engaged with suitable sockets arranged on the plate 13 and arms 27. Between the outer ends of the arms 27 and havingits upper and lower ends revolubly engaged therewith, is a clamp supporting post 29, to the forward edge of which is hingedly connected a pair of clamping bars 30 which are adapted to be clamped into rigid engagement withfthe wire or fence to be stretched, The bars 30 are clamped into tight engagement with the wire or fence by means of clamping bolts 31 which are engaged with the apertured outer ends of clamping lugs 32 formed on or rigidly secured to the outer sides of the clamping bars 30 near the opposite ends thereof as shown.

In connection with the stretching mechanism I provide a wire supporting device by means of which the roll of wire being stretched may be revolubly supported and carried along with the stretcher. The roll supporting mechanism is here shown and preferably comprises a forwardly projecting supporting arm orbar 33 having on its outer end a reel supporting framecomprising a transversely disposed bar 34 which is secured midway between its ends to the arm 33 as shown. On the outer ends of the bar 34 are formed bearing lugs 35 and 36 with which are engaged the opposite ends of a roll supporting shaft 37 whichis inserted through the roll of wire to be stretched. The lug 35 is provided with a circular bearing passage or socket while the lug is provided with a bearing notch whereby the roll supporting bar or shaft 36 may be rigidly engaged with and disengaged fromsaid lug. To the bar 34 opposite the end of the arm 33 is secured a supporting leg 37 which is adapted to be swung downwardly into engagement with the ground to support the outer end of the roll carrying mechanism.

frame or the ends of the tracks 6 and 7 are engaged with a poster other fixed support against which the stretcher is operated. In constructing the frame of the stretcher and the carriage traveling therein, various parts thereof are secured together and braced at their points of connection by angle ironsor other suitable forms of bracing devices.

In using the device for the purpose of pulling stumps or lifting heavy objects the wireclamping bars and wire carrying mechanism are removed from the carriage and to the ends of the clamp supporting arms 27 are connected chains 38 having on their lower ends hooks 39. In the center of the wheel supporting bar or plate 20 of the carriage is arranged a heavy staple 40 with which is connected a frame 41 having secured thereto chains 42 on the lower ends of which are hooks 43. When the device is thus equipped the frame is inverted or turned on end with the forward end thereof in engagement with the ground or suitable blocks placed thereon to receive the frame and is suitably braced and held in position by brace rods 44. When in this position the hooks 39 and 43 are engaged with the stump to be pulled or the object to be lifted and the screw revolved in the same manner as when the machine is employed for stretching purposes. In order to permit the hooks 39 and 43 to retain a firm grip on the stump or otherobject I preferably provide a metal ring or band 45 which is adapted to be fastened around a stump in any suitable manner and which isprovided with oppositely disposed bails or hook receiving loops 46 with which the hooks on the chains 38 and 42 are engaged.

From the foregoing description taken in connection with the accompanying drawings the construction and operation of the in vention will be readily understood without requiring a more detail explanation.

Various changes in the form,'proportion and minor details of construction can be made without departing from the spirit or sacrificing any of the advantages of the invention as defined in'the appended claim. What I claim is: A stretching device of the character described comprismg a frame, uppersand lower centrally disposed guiding and supporting tracks, intermediate laterally disposed guiding and supporting tracks, a stretching car-- riage, guiding and supporting rolls revolubly mounted on said carriage and adapted In testimony whereof I have hereunto set to be engaged with said tracks, a carriage my hand in presence of two subscribing witoperating screw arranged in said frame and nesses.
