TENSION.

SPECIFICATION forming part o f Letters Patent No. 724,285, dated March 31,1903. Application filed January-30,1902. Serial No. 91,935. (No model.)

` ing at Essex, in the county of Kankakee and State of Illinois, have invented a new Tension, of which the following is a specification.

This invention relates to a tension mechanism possessing peculiar characteristics and designed most especially for harvester-binders, although capable of use wherever it is required to subject a cord, ligament, strand, or the like to a uniform tension for any desired purpose.

For a full description of the invention and the merits thereof and also Vto acquire a knowledge of the details of construction of the means for eifecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modiiications, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure lis a perspective view of a tension device embodying the invention. Fig. 2 is a detail section of the tension-creating mechanism. Fig. 3 is a detail section of the parts shown in Fig. 2, taken on a plane at right angles thereto. Fig. 4 is a perspective view of the iixed or bracket member of the tensionbox. Fig. 5 is a perspective view of the movable member of said tension-box.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The operating parts are attached to a suitable support 1, which may be a convenient portion of the harvester-binder framework or other mechanism to which the invention is applied. The twine, oord, ligament, or the like (indicated at 2) is formed into a ball or wound upon a spool and placed upon a holder 3, which may be of any nature or construction, depending upon the type of machine to `which the invention is applied. A series of guide-eyes 4 receive the twine, ligament, or strand 2 preliminary to its passage through the tension-creating mechanism.

The tension-creating mechanism comprises a number of cooperating parts, including a box, a spool, and a tension-spring. The box comprises a fixed or bracket member 5, which is firmly attached to the support l, and a spring-actuated movable member 6. The member 5 is approximatelyof Uform and is attached by one of its side pieces to the support 1 and is arranged with the open end uppermost. The member 6 is likewise of U form and is placed in an inverse position with reference to the member -that is, with its l open end down and its side pieces closing the open sides of the member 5. The upper edge portion of the side pieces of the member 5 are cut away, as shown at 7, to receive guidelugs 8, extended from the upper corners of the member 6. The tension-spool 9 is located in the box formed by the inclosing sides of the members 5 and 6 and is mounted upon a bolt, rod, or pin 10, passed through coincident openings in the ends of said members 5 and 6 and receiving a tension-spring 11, which exerts a pressure upon the member 6, confining the spool 9 with a greater or less pressure, according to the required degree of tension. An adjustingnut 12 admits of regulating the tension of the spring 11 and the consequent pressure exerted against the ends of the spool to resist its rotation when the twine, strand, or ligament is drawn upon. tion of the tension-spool is tapering and is a1'- ranged with the larger portion uppermost. An opening 13 is' formed near the upper end of a side piece of the member 6 for the passage of the twine or strand 2, and a slot 14 is provided in the opposite side portion of Ysaid member for the exit of the said twine or strand from the box. The opening 13 is located near the rear side of the box, whereas the slot 14 is arranged near the front side of said box to conform approximately to the end portions of the twine or strand 2, extended in opposite directions from opposite sides of the spool. The twine or strand 2 is passed around the tapering portion of the spool any desired number of times in order to insure rotation ofsaid spool and preventslipping of the twine or strand thereon. To prevent the twine or strand 2 from creeping downward upon the spool, the opening 13 is located in the side of the member 6 near the upper end of said spool.

The tension upon the twine orstrand 2 is regulated by causing the spring 1l to exert a The body por- IOO greater or less downward pressure upon the' member 6, thereby gripping the spool 1I with a greater or less degree of force. Access may be quickly had to the spool 9 for any purpose by removing the pin or bolt 10 and lifting the member 6 from the member 5.

Having thus described the invention, what is claimed as new is l. In a tension device, inversely-disposed complementary members of approximately U form, a spool inclosed by said members, and a tension-spring for pressing the members against the ends of the spool with a greater or less degree of pressure, substantially as specified.

2. In a tension device, inversely-disposed complementary members of approximately U form, one of the members having an opening near one end for the entrance of the twine or strand to be placed under tension and the side of said member having a slot for the exit of the said twine or strand, a spool inclosed by said members, and means for pressing the members together so as to grip the spool with a greater or less degree of pressure, substantially as set forth.

3. In a tension device, inversely-disposed U -shaped members, one of said members having the upper edge portions of its side pieces cut away, guide-lugs extended from the upper corners of the other member to enter said cut-away edge portions of the first-mentioned member, and a spool gripped between the said members, substantially as set forth.

4. In atension device,comp1ementary members, one of said members having an opening near the end of a side piece and a slotl in the opposite side piece, a tapering spool arranged between said members with its larger end about in the plane of the opening inthe side of the member provided with the aforementioned opening and slot, and means for causing the members to grip the said spool with a greater or less pressure, substantially as set
