SPECIFICATION forming part of Letters Patent No. 232,486, dated September 21, 1880.
Application filed August 9, 1880. (No model.)
To all whom it may concern:
Be it known that I, JAMES F. GORDON, of Rochester, in thecounty of Monroe and State i of New York, have invented certain Improvementsin Mechanical Movements, of which the following is a specification.
My invention relates to mechanical movements; and it consists in a rack divided at a pointbetween its ends into two parts, one of rangement being such that both pinions will be rotated positively together at the same rate of speed in one directioinwhile intheopposite direction one pinion may be given a-greater rotation than the other, or caused to rotate faster than the other during a portion of its revolutions.
In the accompanying drawings, Figure 1 represents a perspectiveview of my improved mechanism with stationary rack, Fig. 2, a longitudinal vertical section of the same; Figs.
it 3 and 4, views of the two racks, showing the parts of the divided rack in their two positions; Fig. 5, a View of the rack-shifting device; Fig. 6, a longitudinal vertical section of the machine with a rack arranged to vibrate; Fig. 7, a perspective view of the compound vibrating rack detached fromtheother parts of the machine; and Fig. 8, a perspective view of the under side of the vibrating arm employed therewith.
This mechanism is designed for use in all places where it is desired to rotate a pinionat different speeds during certain periods without changing the speed of the prime motor, or
to impart a like motion to twopinions at one time and different relative motions at another time, or to cause one pinion to remain at rest duringcertain periods,while the other revolves a greater distance.
The invention may be embodied in machines having stationary racks and traveling pinions, or in machines having stationary pinions and traveling racks, both of which forms are shown tent one to the other.
in the drawings. The racks may be of any formstraight, curved, or angular-and the teeth maybe on any desired face of the same.
I will first describe the machine represented in Figs. 1 to 5, inclusive, in which the stationary rack is shown, and then the form in which a moving rack is employed.
Referring now to Figs. 1 to 5, A represents a horizontal arm having at one end a vertical tubular neck, a, and B a base-frame, provided impart the vibratory motion to the swinging arm.
The wheelU is mounted on a cross-bar in the base-frame, and is driven by a pinion, D, mounted on a-horizontal drivingshaft, E, sustained in hearings in the frame and receiving motion from any convenient source.
F and G represent two pinions, secured, respectively, to two concentric spindles, gh,one of which passes through the other, as shown, andboth of which are supported in the outer end of arm A by a surrounding sleeve, 43. The
two pinions are secured firmly to the respective spindles and gear respectively into horizontal rack-bars Hand I, which are curved to correspond with the path in which the pinions are carriedby the vibrations of the arm A.
The two rack-bars are arranged one directly above the other, and are mounted on the baseframe B. The upper rack, H, is made in one solid. piece, and is secured immovably in place, so that it imparts to the pinion F backward and forward rotations equal in number or ex- The lower rack, I, is divided, preferably at or near the middle, into two parts, in the peculiar manner represented in Figs. 3 and 4, the two adjoining ends being lapped past each other.
this rack is secured rigidly in place 5 but the rear end or section is secured in place by pins The forward end of and slots in such manner that it may have a limited longitudinal.movement, the'extent of movement allowed being made greater or less according to the relative difference of rotation of the pinions desired.
On referring to Figs. 3 and 4 the operation of the divided rack will be readily understood." When the movable end of the rack is forced forward snugly against the other part a continuous rack of the same length as rack H is presented, as shown in Fig. 3. While the rack remains in this position the arm A swings forward and the pinions travel over the racks, which impart precisely the same motion to both pinions, thus turning them without changing the relation of their spindles one to the other. As the arm A swings backward the two pinions receive equal rotations until the lower pinion, G, has passed the division in the rack l, whereupon the rear end of the rack is moved gradually backward endwise while the pinion is traveling over it. The effect of thus moving the rack in the same direction thatthe pinion is traveling is to check or lessen the rotation of the lower pinion without affecting the motion of the upper pinion, which latter consequently turns forward faster than the lower pinion. As the arm A swings forward the lower rack remains extended and stationary until after the pinion G has passed forward over the break or division, so that the two pinions receive the same motions during their entire forward travel. After the lower pinion has passed forward over the break in the rack. the latter closes.
The construction and arrangement are such that the extension of the lower rack does not separate its inner lapped ends from each other. This is a highly important feature of the invention, for the reason that the pinion is thereby enabled to pass over the break in the rack without disengaging or passing out of gear, producing noise or shock, or endangering the teeth of either part.
The movement of the rack may be produced by any suitable devices, many of which will suggest themselves to the skilled mechanic; but I prefer to make use of the devices represented in the drawings.
An arm, J, is pivoted to the under side of the upper rack, H, and bears in a groove or recess in the lower rack, as shown in Figs. 1, 3, 4, and 5, so that its vibration will cause the end movement of the rack-section. Acurved bar, K, is pivoted to the arm J, and extended thence across the front of the frame or machine to a pivoted sustaining arm, L, and is provided on the upper side with two studs, 0, as shown in Fig. 1.
The arm A strikes the studs 0 alternately at the ends of its vibrations and imparts through the bar K and arm J the proper movements to the rack. The divided rack may be sustained in any suitable manner and modified in form and arrangement, provided the pinion is permitted to pass from one section to the other without disengaging. It is, of course, neces sary that whatever distance the rack-section is moved endwise it should in every case be equal to the width exactly of a given number of teeth, in order that the teeth of the lapped ends of the rack may in all cases register perfectly and present a proper surface for the pinion to travel over.
Referring now to Figs. 6, 7, and 8, it will be seen that the arm A is mounted and driven as before, the pinions being located at the outer end of the arm; but it will be observed that instead of the stationary curved racks above described the racks H I are in this case pivoted at one end and arranged to vibrate in a horizontal plane.
In order to effect the longitudinal movement of the divided rack-section, said section is provided with a stud or roller, m, working in a cam-groove or slot, n, in a plate, 0, which is arranged to move at right angles to the rackbar H in guides 19 formed thereon. The movement of the plate 0 transversely of the rackbar is secured by providing said plate with a stud, 1", preferably provided with an anti-friction roller, and arranging the rack-bars in such position beneath the vibrating arm that the stud or roller shall extend upward into the cam-shaped channel or passage 8 formed in the under side of the arm A. As shown in Fig. 6, the arm A and the racks H I vibrate about different centers, the free end of the racks being carried and vibrated by the outer or free end of the arm. As the racks are thus vibrated differently from the arm A, it follows that the plate 0 will be moved back and forth, according to the movement of the arm and the form of the cam-passagein its under side. By varying the form of said passage the movement of the plate, and consequently the movement of the rack-section, may be modified as desired.
It is apparent that the pinions may be made to rotate in a fixed position by causing the rack to move in the proper direction, the shifting device first described or its equivalent being used.
I am aware that two racks have been lapped together at their ends, out of line with each other, and arranged to be adjusted endwise with relation to each other and fixed permanently in position. By halving the ends of my racks together, and thus bringing them in line, I am enabled to pass both through the same space or guide, and to have them both act upon one and the same narrow pinion. The combination of automatic shifting vmechanism with the rack enables the same to impart the differential movement to the pinion, as described.
Having thus described my invention, what I claim is- 1. In combination with a traveling pinion, a rack divided and lapped at a point between its ends, and mechanism arranged to move one or both ends of the rack endwise, substantially as described, to give the pinion a greater rotation in one direction than in the other.
2. In combination with the two pinions, the continuous and the divided rack, the latter having one endmovable in order to impart a differential movement to the pi'nions.
3. The combination of the vibratory arm and the two pinions thereon, the stationary rack, the divided rack, having the movable end, and mechanism, substantiallysuch as shown, actuated by the arm and arranged to adjust the movable end of the rack.
4. The combination of the movable rack-section, arms J L, bar K, and the movable arm, arranged to reciprocate the bar.
travel in relation to the other, substantially as 2 5 described.
