HENRY '1'. .MILVLER or non "spaincs, 'aaxansasf -DEVICE' FOR. smmcnmc W'I'RE Am') TI-IE'LIKE.
To all whom it may concern:
7 Be it known that I, HENRY ,T. MILLER, a citizen of the United States, residing at Hot Springs, in the county of Garland and State of Arkansas, have invented certain new and useful" Improvements in Devices for Stretching Wire and the like; 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 make and use the same, reference being had to the accompanying drawings, and the letters and figures of reference marked thereon, which form a part of this specification. I V
a My invention relates to certainnew and useful improvements in devices for stretch ing wire and the like, it being also useful in such other analogous arts as properly fall within its adaptation.
The qbjectof my invention is to provide I means for effecting a continuous operation of the power or stretching member, said means including ratchet wheels and a plurality of pawls designed to span and operate the said ratchet wheels. I
Another object of my invention is the provision of means for operating the device, the said means being arranged within a frame, the contour and compactness of which will permit the ready use of the device in stretching Wire up to,- and a distance beyond the last post in the fence.
A further object of my invention is the provision of an eflicient device possessing many advantages such as the ready manipulation of the device in turning corners without an additional post, the taking up of the slack in a wire fence without careeningand displacing the posts, and the general handling and operation of the device in a minimum amount of time and with a small degree of labor. e
.Miy' invention further consists in the ar rangement and combinationof arts herein,- after' described and pointed out in the appended claims.- y, p

Application filed September 23, 1914. Serial N o.- 863,1 31 I cross rod or brace 3, and the strengthening and securing block 4. The block is located at one end of the frame, and the cross rod or brace 3 is thereof. p v V I The side bars 1 and 2 are preferably ar' ranged in parallel relation to'each other and at one end of the frame they are tapered into points-5 and 6, whileat the other end there of they are uniformly shaped as at 7 V and 8. Suitable bearing surfaces 9 and 10 are also providedon each side bar, and serve,
the purpose of properly alining and supporting the device when used for hoisting as shown in Fig. 6. I As shown in the my invention the cross rod 3 consists of a bolt 11, an encircling sleeve-12 and a nut 13,
the purpose of which is to secure increased strength and rigidity. The block 4 is held positioned at the other v end present embodiment of 1 between the sidebarsfby bolts 14 and nuts 15 and by reason of'its peculiar shape and construction serves a three-fold purpose, namely the forming of a strong frame; the providing'of a pivotalconnection for the operating lever; and its use as the fastening end for the holding or securing chain. With regard to its forming a part of the frame, I
the integral rectangular formation thereof, is conducive togreater strength and effectiveness. The block is formed with the sides 16 and and the tubular or sleeve ends 18 and through which the bolts pass. The end 19 is cutaway as at 20, for the reception of the operating lever. With regard to this saidlever it will be seen that it is firmly positioned upon the block in this cutout portion and pivots upon one of the bolts which secure the block in'the frame. The
block is also provided with the fastening end 21 which is formedintegral-ly with the 7 block as shown. A ring 22 may be used in connection with this end of the block in securing the chainthereto.
The ratchet wheels 23 and 2d are arranged within the frame upon the shaft 25. Between these ratchet wheels is positioned a chain link engaging member 26. This member is provided with the usual projections for engaging and holding the several links as the chain passes through as will be readily understood. As shown I secure the ratchet wheels'and chain link engaging member by bolts 27 (see Fig. 4) but they may be formed as one, or in any other suitable and convenient way.
The lever 28 which is pivoted on one of the bolts passing through the block t, carries two pawls 29 and 30. cated above the pivotal point of the lever and is of greater length than the pawl 30 which is located beneath the pivotal connection of the lever. These pawls pivot on the lever at 31 and 32 respectively, and have enlarged engaging heads 33 and 3 1 which span the distance between the ratchet wheels, and evenly operate the same. As shown these pawls are designed to engage the teeth of the ratchet wheel because oftheir weight, as will be readily understood. However, springs 29 and 30 may be employed to assist the pawls in contacting with the ratchet wheels in the usual way, as shown in Fig. 2.
In operating my device as shown in Fig. 1, I employ a chain 35, one end of which is secured to the clamping bars 36 which hold the wire mesh, and the other end of which passes around the chain engaging member 26. A short chain 37 is fastened to the link 22 and further secured to a post 38. When in this position, the lever is now operated, and as it is oscillated back and forth a continuous pull will be given the chain 35 by reason of the pawls 29 and 30 alternately engaging the ratchet wheels and moving the ratchet wheels and chain engaging member in one direction.
Referring to Fig. 2 my device is shown as applied for bringing the wire up to the post 38. When used in this manner the device is turned at right angles to the position shown in Fig. 1, and the point 5 and 6 of the side bars forced a short distance into the post. The short chain 37 which is secured to the ring 22 is fastened to the post by a hook 39. The chain 35 is connected to the clamping bar as in the first instance and passed around the chain engaging member located between the ratchet wheels. When in this position the device is capable of drawing the wire up to and beyond the post 38, the short chain 37 acting to steady the device when the lever is oscillated and the pull exerted upon the wire. This use of the device is highly ad- The pawl 29 is lo-' vantageous in fastening the wire on the last post and in the turning of corners. In taking the slack out of a fence, two clamping bars are used between the posts and the de vice suitably connected between the said bars and operated, as will be readily understood.
In Fig. 6 of the drawings my device is shown as used for hoisting or lifting purposes. It is mounted upon the supports 40 and 41, the bearing surfaces 9 and 10 properly alining the device as hereinbefore mentioned. The chain is then passed over the-chain engaging member and connected to the block 42 put under the house or other structure which is to be raised.
From the foregoing it will be obvious that a practical, compact and efficient device is provided, capable of fulfilling the many uses to which a device of this character is sub jected and requiring on the part of the person using the same very little time and a minimum amount of labor.
I-Iaving described my invention and set forth its merits, what I claim is:
1. In a device of the class described the combination of a frame having engaging means at one end thereof and a block at the other end thereof serving to secure means for connecting the frame to a post, ratchet wheels mounted in said frame, a chain engaging and holding member located between said ratchet wheels, a plurality of pawls bridging the chain engaging and holding member and engaging the said ratchet wheels, and means including a lever mount ed in said frame and carrying the pawls, the said lever having its pivotal connection in the said block constituting part of the said frame, intermediate the pivotal'connection of the said pawls for operating the said ratchet wheels in one direction only.
2. In a device of the class described the combination of a frame composed of parallel side members tapered at one end and braced apart from each other, aspacing block interposed between the other ends of the members and formed with transversely extending tubular sleeves for the passage of clamping bolts, one of said sleeves being cutaway, an operating lever carrying pawls moimted in the cut-away portion of said sleeve, and a chain engaging and holding member and ratchet wheels mounted in the frame, the ratchet wheels being at opposite sides of the chain engaging and holding member and positioned in operative relation to the pawls of the lever.
In testimony whereof I affix my signatur in presence of two witnesses.
