MECHANICAL MOVEMENT.
SPECIFICATION forming part of Letters Patent NO. 471,931, dated March 29, 1892.
Application filedJnne 18, 1891. Serial No. 396,758. (No model.)
To all whom it may concern:
Be it known that I, JOHN G. YOUNG, J r., a citizen of the United States of America, residing at Hyde Park, in the county of Norfolk and Commonwealth of Massachusetts, have invented certain new and useful Im provements in Mechanical Movements, of
which the following is a specification.
My said invention is designed to convert I0 rotary into reciprocating movement. I have applied it to operate the plunger of a machine for making boxes; but it is applicable also to other machines, and is especially advantageous where uniform motion is required or direct and close connection with the plunger.
My invention is illustrated in the accompanying drawings, in which- Figure 1 represents the reciprocating bar and case in side elevation with the shaft of the pinion in section. Fig. 2 shows an edge View on line 00 a: of Fig. 1. Fig. 3 is aview of a transverse section on line y y of Fig. 1. Fig. 4 is a side elevation of a modification, and
Fig. 5 a transverse section on linezzof Fig. 4.
In the drawings, A represents the drivingshaft, which turns in a fixed bearing a. It carries a pinion B, engaging with the reciprocating rack-bar b. In the form shown in Figs. 1, 2, and 3 the rack-bar, except at the ends, is in the shape of a T-iron, as shown more clearly in Fig. 3. The side flanges are indicated at c c and the web at d. The teeth of the rack-bar are shown at 6 set at right an- 3 5 gles on both sides and at acute angles at the ends, so that the end of the rack portion of the bar may travel around the pinion. The
rack-bar is located in a case F, which has a central longitudinal slot f in the front plate h, extending from end to end within the crossbars of the case, (marked g.) As shown, the side flanges c c extend beyond the rack portion of the bar at both ends in the form of a plain bar, and the ends fit snugly in the space between the cross bars or plate g of the case and the back-plate h of said case. The arrangement of the parts is such that the rackbar may be shifted from side to side in the case without longitudinal movement therein, but is held by the side walls of the case with its teeth in engagement with those of the pinion. The front plate in Fig. 1 and the cross bar or plate g are partially broken away to show the position of the rack-bar. The case F is connected by any convenient means to 5 5 the part to be moved, and may reciprocate between or within suitable guides in direct lines, while the rack-bar shifts from side to side in the case at the end of each direct movement. As the pinion is turned in the direction of the arrow in Fig. 1, for example, the rack-bar, with the whole case, moves upward until the inclined tooth 1 at the lower end of the rack-bar reaches the pinion, when it engages with the teeth of said pinion, and the rack-bar is thereby drawn over laterally. The pinion next engages the tooth 2 on the rack-bar, by which the lateral movement is completed, and the bar travels down on the other side of the pinion. The resistance of the work or any suitable means, as springs, may be used to keep the ends of the rack-bar in engagement with the pinion as the rackbar is shifted from side to side.
In the modification shown in Figs. 4 and 5 the shaft may extend through and the rackbar b is without flanges, but is held instead snugly between the front and rear walls of the case and engages with fixed racks 7c and and k in the edges of the case. These hold the rack-bar to the case, and as the rack-bar moves on the pinion it carries the case until the end of the rack-bar reaches the pinion, when th e inclined teeth engage with the pinion with the effect described in connection with Figs. 1 and 2. To insure the movement of the rack-bar, I provide abent lever 'm at each end of the case. They are pivoted in the casein line with the pinion-shaft and aside from the pinion, so that as the case reaches the limit of 0 its movement the shaft strikes the tail of the lever. The other end of the lever is in line with the rack-bar or some projection thereon at or near the end, and thus the rack-bar is pressed from one side to the other, and as 5 ment, but on the opposite side thereof, and moves in the opposite direction,carrying the case with it, as before explained.
I claim as my invention 1. In combination, the stationary pinion, the casing, the rack'bar shiftable laterally relatively to its casing and. having a pairof inclined teeth at each end anda straight row of teeth on each side, terminating at each end in one of said inclined teeth, and bearings for the rack-bar to prevent longitudinal movement in relation to its casing, substantially as described.
2. In combination, the reciprocating andshifting rack-bar, the stationary pinion, the
casing for the rack-bar, longitudinally movable therewith, and the automatically-operating levers for shifting the rack-bar, substantially as described.
3. In combination, the casing having hearing sides formed with teeth, the shifting rackbar havingcorrespondingteeth, and the stationary pinion, substantially as described.
In testimony whereof I aflix my signature in presence of two Witnesses.
JOHN G. YOUNG, JR. lVitnesses:
