REVERSlNG-GE AR.

sPEoImcArIoN To all whom it may concern.-

Be it known that I, ERNST G. SMITH, a citizen of the United States, residing at Oolumbia,in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements .in ReversingGears; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention isto provide a simple and direct gear which is automatically reversed at regular intervals to cause a' reciprocation, oscillation, or vibration of a plunger,

paddle-shaft or other device such as are used in churns, washing machines, &c.

Further objects and advantages of my invention will appear in the-following description, and the novel features thereof'will be particularly pointed out in the appended claims.

In the drawings: Figure 1 is,a front view of gear-reversing mechanism embodying my invention; Fig. 2 is a side view of the same; Fig. 3 is a transverse ser ion on line mx of Fig. 4, showing. the swiveled standard, the stop-lever'and connected parts; Fig. 4 is .a plan view of the slide', showing the stop-lever and indicating in dotted lines the position thereof when the belts are both held upon the loose pulleys; Fig. 5 is a section on line yy of Fig. 1; Fig. 6 is a detail'section, line z--z of Fig. 1. Fig. 7 is a detail view of one of the guidesk; Fig. 8 is an end view of the swivel.

Fig. 9 is a detail viewof the worm gear and" earn 0. Y

A in Figs. 1 and 2 represents a port on of the casing of a washing or other machine, to

i the main-shaft, B, of which is attached the D represents a supporting-arm, provided at its extremity with a bearing, d, having a removable cap, d, and E represents a swiveled standard, provided at one end with a bearing-sleeire, F, which fitsin thebear-ing at the end of the supporting'armand is locked therein to hold'said standard at any desired inclination by the cap, d. This sleeve 1 forms the bearing for the outer end of the shaft, G, the inner end thereof being mounted in a suitable bearing, (not. SliOWii) in ilieside of, the machine to which the reversing mechan-t ism isattached. This shaftcarries a pinion,

forming .part of Letters Patent No. 489,104, dated January'3, 1893. Application filed April 29, 1892. $erial No. 431.169. (No modeld slide, L, being secured slidably thereto by the guides, k 70, which are in the form of clips, as shown in Fig. 7, and are bolted through perforations k in the plate K, and extend under the slide L. This slide L is provided with a depending arm, M, which carries a swivel, N, provided with pins or studs,- 71 n in the path of a cam, 0, upon the adjacent side of the worm-gear. This swivel is also provided with stops, it n, opposite to said pins or studs n n, to engage the edge of the arm M to prevent complete rotation.

P representsasliding-holder, rovided with lateral arms, p 19, carrying belt-hooks,p p', to engage the belts Q Q, and to this holder is pivotally connected the locking-lever R which is provided with a lateral stud 'r to en gage a notch r in the upper end of the-arm M of the slide L, said arm being extended vertically above the plane of the slide to lie in contact with said lever. The lever B is held in this engaged and normal; position by the straight line connecting said points of connect-ion of the spring lying upon that side of the pivotal point of the lever toward the notched arm, above described, whereby the arm is held in place. It will be understood that the holder P, which carries the belt hooks, slides upon the plate K, receiving its reciprocating motion from the slide L through the lever B which latter is pivotally connected to said holder, and therefore when said lever is locked with the slide L the holder P moves T is the fixed pulley upon the main shaft,

and T T are the loose pulleys, upon opposite sides of the fixed pulley.

U is a straight belt and U is a crossed belt.

In'operation, one of the belts being arranged upon the fixed. pulley, the shaft is rotated,

thereby operating the worm-gear and carry- 7 that previously accomplished, and again shifts the belts.

The pins or studs for the engagement of the cam may be attached directly to the depending arm, but the above construction is preferable for the reason that more certainty of engagement is attained, and the parts are less liable to be strained .or forced out of position.

When it is desired to stop the mechanism, the locking lever is disengaged from the slide and swung to the right, until its V-shaped projection, it, lies between the guide-pins u, M which are 'attached'to the bearing plate 10', above described. When in the position shown in dotted lines in Fig. 4, the. belts are both held upon the loosepulleys, thereby stopping the operation of the mechanism. If,when the a bearin g plate, a sliding holder, a slide, a cam locking-lever is disengaged from the slide, its V-shaped projection is not in alignment with the space between said guide-pins one of its .beveled edges. will engage oneot the pins as also shown in dotted lines in Fig. 4, and draw the lever and holder to the position in which the belts are upon. the loose pulleys.

Having thus described my invention, what I claim and desire to secure by Letters ,Patent of the United States, is:

1. In a reversinggear, the combination with engaging the slide, and means to operate the cam, 'of a locking-lever pivotally-connected to the holder and having a stud to engage a gagement with the slide, substantiallyas speci- 2.
