l-lAlVlE-'TUG ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 271,260, dated January 30, 1883.

Application filed July 17, 1882. (No model.)

To all whom it may concern Be it known that I, ISAAC W. NUMAN, a citizen of the United States, residing at Ganton,in*the county of Stark and State of Ohio, have invented certain new and usefulImprovements in Hams-Tug Attachment and Adjusting Device, of which the following is a speciicaton, reference being had therein to the accompanying drawings.

Fig. 3 is a perspective view ofthe last said parts in the positions occupied when put together. Fig. 4 is a section on line .e nu, Fig. l. Figs. 5, 6, and 7 are perspectives of details. Figs. 8 and 9 are outside views of slightly-modied forms. Fig. l0 is a section on line y y, Fig. 9. Fig. 11 is an enlarged view of a part of Fig. 10.

This invention relates to improvements in adjustable hame-tugs ol' the kind represented broadly in my Patent No. 254,683, dated March 7,1882. In said patent I showed and described a tugadjusting device consisting ofa skeleton metal iramehaving a screw-rod mounted therein for moving the end of the tug forward and back; but I have foundthat for some purposes an adjusting mechanismof the character set forth in said patent is of an inferior nature, especially where frequent adjustment is required, and where the adjustmcntmust be over comparatively long` distances, inasmuch as the threaded rod must be rotated a considerable number of times to produce the requisite movement. Moreover, the skeleton-frame shown in said patent I find to he more expensive and heavier than i's desirable for some kinds of harness.

This invention relates toa tug attachment and adjusting device having an inclosing-case which, while being lighter than the skeletonframe and less expensive, is nevertheless as strong, and is adapted to permit the forward end ofthe tug to move with more freedom than when a" frame is used ot' the character shown in said patent.

To this end the invention consists in form ing a hollow case having continuous Walls on all sides, so as to-forin a chamher,\vitl1in which the forward end of the tug is received and confor this purpose.

cealed. As the casing is made continuous on all sides, it may be made of much lighter and cheaper material than when a solid, heavy skeleton metal frame is employed.

The invention relates, further, to a mechanism for speedily and readily adjusting the tug, and relates, also, to various matters which will be fully described and set forth in detail hereinafter.

In the drawingsI have shown my invention as appliedv to a hams-tug in several modified ways, though it will he readily understood, after an examina-tion ofthe drawings and the following description, that in matters of detail the device may be varied without departing essentially from the invention.

The supportingand concealing casing is represented by A. This is made with continuous walls on all sides, so as to form a hollow chamber. As the material of which it is composed extends continuously all around,`it may be made of a light material, such as tin or other thin metal or wood, and I have found that papier-1nach even -may be used successfully This is covered with leather, which is arranged to form a tight jacket around it, the leather being kept in form and shape by the casing within. The casing provides an open chamber, within which the forward end of the tug can move freely, there being none ofthe cramping or binding that is experienced when the end ot' the tngis compressed tightly between iiexible parts. At the forward end the tug is provided with an eye, O, for fastening it to the haines. This eye is secured in place in the casing by means ot' one or more screws or rivets passing through from one side of the casing to the other, as shown at c. The supporting part C of the eye-piece has an inner stem or shank, C2, which is seated within the end of the casing to support the edges at the end, and has also an expanded part, c', which may be made ornamental for providing a strong closing-piece and cover for the edges an d end ot' the casing. Y

The tug is represented by D. Itis provided with a series of perforations, cl d, near its forward end. Said end is adapted to slide in and out of the casing A at the rear open end. Then the length of the tug is to loe changed it is moved in or out far enough to bring the IOO proper aperture d opposite to the apertures a u', which are formed in the side of the casing A. Through these apertures there passes a pin, E, adapted to go through the tug. The pin is prevented from seriously wearing or straining the casing or the leather covering thereof by means of an eyelet, E', fastened in the aperture a and an eyelet, E2, in the aperture a'. With thev pin there is combined a locking device adapted to prevent its being accidentally withdrawn. I prefer is shown in the drawings at F, it consisting of a sliding bolt seated beneath the plate E3, which latter is preferably formed in one pi'ece with the eyelet or part E2.

Having thus described what I consider the essential features of my invention, I will now set forth the devices which may be combined therewith' to make a still more advantageous tug attachment and adjusting mechanism. Thus the hollow light casing may be strengthened by means of two strips, G G, of steel, opposedto each other-that is, placed upon opposite sides of the casing and secured thereto by rivets. When the lcasing (strong enough ot' itself under ordinary circumstances by having the walls continuous) is supplemented by these metal strips there is produced a very durable tug attachment, capable of withstanding the most serious strain and wear. Again, l prefer to attach the pin E to a dat metal spring, H, so that it shall automatically pass through the apertures and tend to, be held by the spring in place. I is a leather cover, situated behind the spring H, to form a facing or jacket for it, so that the horse shall not be affected by the metal ofthe spring. The leather preferably extends beyond the spring, as shown at t', to form a convenient flexible handle to pull the spring back.

ln Fig. 7 I have shown an improved form of a loop or buckle to be combined with the easing and the tug. 1t is constructed in two parts, one consisting of the back plate, J, the upper loop, J', the lower loop, J2, the end loop, J2, and the arms J4 J4, provided with rivetpieces j j, andthe other part consisting of a cross-bar, J 5, provided with perforations at the ends adapted to tit upon and be riveted against the arms J 4.

Atj j the back plate is riveted to the inner hollow casing, A. It is cut away or provided with a recess, J6, which permits the pin E to be readily inserted and withdrawn, and also allows the spring H to lie close to the casing.

Heretofore the loops or buckles corresponding to those just described have been secured to the leather parts by means of stitching; but for heavy harness I tind this method of riveting the loop or buckle to the attachment casing to be much better. The cross-barJ5 of this loop or buckle may be perforated at the center, so that the central part thereof shall act as the eyelet E2. With it also may be formed integrally the plate E3, beneath which lies the lock F. This latter is preferably made The form oflock which of awire or rod bent to have the outwardly-projecting partf, (in the slotf-,) by which it can be moved back and forth. There is a groove in the under side of the plate, which operates as a guide for the lock. The pin E is provided with an aperture, into which the lock passes, though a slot may be used instead of the aperture, if desired.

In Fig. l() I have shown the tug attachment in the form in which I prefer to make it for use with breast-collars. The manner of securing it to the collar-will be readily understood.

It will be seen that the hollow casing A provides a strong support for the eye-piece G for the spring which carries the locking-hinge and for the loops at the rear end, all of which are formed separatelylfrom the casing and riveted or otherwise secured thereto. The casing insures that all of the parts of the tug attachment shall be held constantly in substantially the same position relatively to each other, and is therefore much better than the casing devices which have been made of leather, and therefore liable to stretch so as to vary the positions of the parts.

What I claim isl. The herein-described tug attachment, consisting of the eye-piece (.l, the pin E, which fastens the tug and is'held in place independently of the tug, and the devices for preventing accidental withdrawal of the pin from the tug, in combination with the hollow casing A, having continuous walls on allsides, and formed separately from said eye-piece C and pin E, and connected, substantially as set forth, to thedevices which hold pin E,wherebystrain ing of the leather parts is prevented and a concealing-chamber is provided for the forward end of the tug.

2. The combination, with the hollow casing A, of the tug provided with a series of perforations at its end, the pin E, the perforated plates or eyelets E' E2 in the walls of the cas'- ing A, and means for preventing the withdrawal of said pin, substantially as set forth'.

3. The combination, with the casing, the haine-tug provided with perforations, and the pin adapted to pass through the perforations, of the spring permanently secured to said pin, substantially as set forth. l

4. The combination of the casing, the tug provided with perforations, and the pin E with the spring and the leather covering for said spring, extended beyond the end thereof to form a iiexible handle, substantially as set forth.

5. The combination of the hollow casing having continuous walls on all sides, the eye C, formed separately from and rigidly secured to said casing, the pin E, passing through the rear end of the casing from one side to the other, the lock F, the plate E2, secured to one side of the casing, and the devices which prevent accidental withdrawal of the pin E after it is unlocked, secured to the casing on the side opposite to the lock, substantially as set forth.
