MECHANICAL MOVEMENT.

SPECIFICATION forming part of Iletters Patent No. 769,327, dated September 6, 1904.

Application filed November 2'7, 1903. Serial No. 182,799. (No model.) i

To all whom, it may concern.-

7 Be it known that I, J osnrrr SHELINE, a citizen of the United States, residing in the township of Valinia, in the county of Cass and State of Michigan, have inventedcertain new and useful Improvements in Mechanical Movements, of which the following is a specification.

This invention relates to improvements in mechanlcal movements. 7 V The ob ects of this invention are, first, to

provide an improved mechanical movement adapted to convert reciprocatory into rotary motion, or vice versa, which may be quickly ad usted to drive a shaft in either direction; second, to provide an improved mechanical movement adapted to convert reciprocatory into rotary motion, or vice versa, which is simple and compact in structure and strong A structure embodying the features of my invention is clearly illustrated in the accompanying drawings,forminga part of-this's'pecification, in which a Figure l is a detail sectional view of my improved mechanical movement, taken on a line corresponding to line 1 1 of Fig. 2. Fig. 2 is a detail longitudinal sectional View taken on a line corresponding to line 2 2 of Fig.- 1, portions being shown in full lines to show their structure. Fig. 3 is a detail cross-sectional view taken on a line corresponding to line 3 3 of Figs. 1 and 4:, showing details of the connecting means for the pinions B to the shaft B,

- the rocker c and its bearing being shown in full lines. Fig. 4: is a detail sectional view taken on line i 4:' of Fig. 3, portions of the locking means being shown in full lines. Fig. 5 is an enlarged detail side elevational view of the shaft B, showing the chamber G therein to receive parts of the mechanism for connectthe pinions.

ing the pinions B thereto. Fig. 6 is an enlarged perspective view of one of the keys 0?.

Fig. 7 is an enlarged perspective view of one of the rock-shafts E by which the trip-pinsc are carried.

In the drawings the sectionalviews are taken looking in the direction of the little arrows at the endsof the section lines, and

similar letters of reference refer'to similar parts throughout the severalviews.

Referring to the drawings, a yoke-like head A is provided. This head is secured to the pitman A I B is the shaft, whichmay either be a driven or a driving-shaft, according to the use desired. Mounted side by side on the shaft B are a pair of mutilated pinions B. These pinions are adapted to be alternately connected to the shaft B. The means by which this is accomplished will be hereinafter pointed The pinions B are provided with gearteeth b-on one-half their circumference. These teeth are out within the perimeter of the pinion, so that the pinions afford an even support for the head, which is provided with suitable ways to receive the same and is adapted to reciprocate thereon. The head A is pro vided with racks (0, adapted to mesh with the teeth 6 of the pinions B. These racks are oppositely arrangedthat is, one is arranged on the upper side of the head and the other onthe lower. The pinions B are alternately connected to the shaft 13 by the'sliding keys 7 d, which are seated in the chamber G, formed in the shaft, as clearly appears in the drawings. I A

In the bottom of the chamberG, mounted upon a suitable bearing-blockc', is the rocker 0, against which the inner ends of the keys cl resta Thus supported when one of the keys d is in its inner position the other key must of necessity be in its outer position. The keys (Z are notched to straddle the rocker 0, so that the rocker is held'in position on its bearing. Radial slots 6 are formed through The keys d are. adapted to project into these slots when in their outer position, and thereby secure the pinions to the shaft. As before remarked, the keys (Z are alternately held in their outer or engaging position, so that the pinions are alternately secured to the shaft.

Slidably secured within the slots 6 by the pins c', which engage slots c" therein, are blocks d. The inner ends of these blocks rest against the keys (Z.

At each end of the head A. is a rock-shaft E, having a pair of inwardly-projecting arms 6 thereon. (See Figs. 1, 2, and 3.) Crossarms E are secured to projecting ends of the rock-shafts E. These cross-arms are connected by links E, so that the rock-shafts are actuated in unison. One of the arms 6 on each of the rock-shafts E projects into the path of the pinions B and striking the sliding blocks (Z force the same inward, thereby forcing the key d inward, releasing one pinion from the shaft and through the rocker 0 securing'the other thereto. On the opposite ends of the stroke the trip acts in the same manner, releasing the one pinion and securing the other. The shaft is thus driven continuously in one direction. The trips or arms 0 are arranged on the shafts E so that when one of them is thrown up into position in one of the ways the other is thrown down. When it is desired to change the direction in which the shaft is driven, the trips are shifted, which reverses the connection of the pinionsthat is, the pinions will be connected to the shaft at opposite ends of the stroke than when the trips were in the first position. The direction is by this means very quickly changed as de sired. The ways are formed in the head A by securing a pin f therein, so that the pinions are separated thereby and travel along each side of the same, as clearly appears in Fig. 3.

My improved mechanical movement is very compact and simple in structure and is not likely to get out of repair. The same may be quickly reversed. The structure is very light and compact.

I have illustrated and described my improved mechanical movement in the form preferred by me on account of its simplicity and compactness. I am, however, aware that it is capable of considerable variation in structural details without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
