JOHN L. RACE, OF PORT WASHINGTON, IVISGONSIN.

MODE 0F SUSTAINING AND PROTECTING COUPLINGS OF SHAFTING.

Specification of Letters Patent No. 34,982, dated April 15, 1862.

To all whom it may concern:

Be it known that I, JOHN L. RAGE, of Port Washington, in the county of Ozankee and State of Wisconsin, have invented a new and useful device for covering the knuckles or joints of rods used in machinery-such, for instance, as the knuckles of the tumblingrods of threshingmaC-hineS; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l, is a side view of my invention; Fig. 2, an end view of the same; Fig. 3, a longitudinal vertical section of the same, taken in the line m, a', Fig. 2; Fig. 4;, a plan or top view of the' same; Figs. 5 and 6, detached views of a slide pertaining to the same; Fig. 7, a detached view of an adjustable box pertaining to the same; Fig. 8, a transverse vert-ical section of the same, taken in the line y, y, Fig. 7.

Similar ltters of reference indicate corresponding parts in the several figures.

In many machines jointed shafts or rods which have a rapid motion are exposed at the outer side and the knuckles or joints are very liable to catch the clothes of the attendants, and frequently serious accidents occur' by persons being drawn in contact with the working parts of the machine.

This invention is designed to obviate this difficulty and to this end I box theknuckle or joint of the rod in such a manner as to serve as an efficient protection and at the same time admit of the rod being adjusted to any desired angle required.

rIhe invention consists in placing the joint or knuckle in an adjustable box which is fitted within a larger box or case, and arranged substantially as hereinafter described. i

To enable those skilled in the -art to fully understand and construct my invention I will proceed to describe it.

A, represents a box or case of rectangular form and permanently secured to the framing of the machine or to any fixture adjoining it. This box or case may be of wood or metal, wood probably will be most generally used. The case A, is provided with a lid a, the ends of the case however are open, and

in one end a rest or support b, is secured by a pin c, which passes horizontally through the case. The rest or support Z), is formed of a square piece of wood, it is allowed to turn freely on the pin c, and may be adjusted higher or lower by inserting the pin c, through any of a series of holes d, in the case, see Figs. l and 3. At the opposite end of the case A, there is fitted a horizontal bar e. This bar has tenons f, at its ends, which tenons it in grooves g, made in the inner sides of the case at its upper end. The bar e, may be readily removed from the case A, when necessary, and to its outer side there is attached a metal slide L, which is slotted longitudinally the greater portion of its length, as shown at 9'., and is connected to the bar c, by a screw j, which passes through the slot z', into bar e. The lower end of the slide h, is provided with a horizontal lip or projection 7:.

B, is a box of oblong rectangular form, provided with a lid Z. This box B, is fitted within the case A, one end of it resting on the support b, and the opposite end resting on the lip or projection 7c, of the slide L, as shown clearly in Fig. 3. Within this box B, the knuckle of the shaft or rod is placed, as shown by the dotted lines in Fig. 3, and it will be seen that the box B, may be adjusted to any angle to suit the inclination of the shaft or rod by regulating the height of the support b, and slide z-,the support b, in consequence of fitting loosely on its pin c, is allowed to turn and adjust itself to the box B, so that the bearing surface of the support will be parallel with the bottom of the box B. By this arrangement therefore, it will be seen that the knuckle may be perfectly inclosed and the box which incloses it adjusted to suit any angle or degree of inclination of the knuckle shaftV or rod.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is The box B, fit-ted within the case A, and resting on the adjustable support b, and slide 7L, all being combined and arranged substantially as and for the purpose herein set forth.
