GEARING DEVICE.

Specification of Letters Patent.

Patented Mar. 12, 1912.

Original application filed January 24, 1910, Serial No. 539,852. Divided and this application filed September 10, 1910.

' citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Gearing Devices, (being a division of an 1 application for Letters Patent of the United States for improvements of a bottle washing and rinsing machine, filed January 2 1, 1910, Serial No. 539,852,) of which the following is a specification.

My invention relates to improvements in gearing devices for converting the continuous rotary motion of a main shaft, into an intermittent rotary motion of another shaft and into an intermittent reciprocating motion of a sleeve, and the object thereof is to accomplish the transformation in such a manner that, during each and every period of revolution of a shaft, an intermittently revolving shaft and a reciprocating sleeve would pass through a cycle consisting of a movement of the sleeve in one direction the intermittently revolving shaft remaining stationary, followed by the motion of the shaft the sleeve remaining stationary, followed by the movement of the sleeve in the opposite direction the shaft continuing stationary, followed by an interval during which both remain stationary.

With this and other objects in view, my invention consists of the combination, construction and the arrangement of parts as will be hereinafter more fully described and claimed and illustrated in the accompanying drawings, it being understood that changes in form, size, shape and other minor details may be made within the scope of my claims without departing from the spirit or sacrificing any of the advantages of this invention.

In the accompanying drawings, Figure 1, is a side elevation of the device; Fig. 2, is a front elevation of a pair of bevel-gears in connection therewith; Fig. 3, is a plan view of Fig. 2; Fig. 4;, is a front elevation of a pin and slotted bar in connection with the device, and Fig. 5, is a side elevation of a machine in connection with the device.

Similar figures refer to similar parts throughout the several views.

On a main shaft 1 is mounted a gear 4 Serial No. 581,345.

meshing with a spur gear 5 mounted on an intermediate shaft 6. On the shaft 6 is mounted a pinion 7 meshing with a driving gear 8 mounted on a driving shaft 9. On the shaft 9 is mounted a mutilated gear 10 and a crank 12 carrying a pin 13. The mutilated gear meshes with a follower 1 1 mounted on a tubular driven shaft 15 rev- .olubly supported on a post 16 at right angles with the driving shaft. The pin 13 rolls in a slotted bar 17. The gears 10 and 14 are so connected that the uniform rotation of the gear 1.0 produces a given intermittent motion of the gear 14, and are so constructed that the gear 14 is rotated by the gear 10 through a definite angle and is then held securely in its position until it is again put in motion.

As shown in the drawings, the axes of the gears are intersecting and are therefore constructed from two truncated cones. In the combination shown the gear 11 passes through a quadrant during one-sixth of the period of the gear 10, that is, the gears have a velocity ratio of two to three. After the gear 14 has passed through a quadrant it remains stationary until the gear 10 completes its revolution, the gear 10 having teeth on one-sixth of its conical surface only.

The teeth are constructed in the usual manner, except that the last tooth of the gear 10 is connected with the first tooth by a smooth conical surface 19 joining the root of the last tooth with that of the first, except for the clearances 20, 20. In order to avoid the danger of the teeth of the gears jamming every time they become engaged, the face 21 of every last tooth of the follower, opposite to the face 22 of the last tooth of the driver is projected and is connected by a concave conical surface 23 with the face 2 1 of a tooth on the follower which must become engaged by the face 25 of the first tooth on the driver, which results in the smooth surface 19 of the driver rolling over the smooth surfaces 23 of the follower successively whenever the teeth become disengaged.

The slotted bar 17, is mounted on a bar 26 which is constrained to slide in a vertical plane parallel with the plane of the crank 12 and perpendicular to the bar 17. The pin 13 rolls in the slot 27 of the bar 17 while the crank 12 revolves uniformly with the shaft 9 and imparts to the bar 17 a harmonic motion, that is, the velocity of the bar 17 is zero when the angle between the crank 12 and the bar 26 is either zero or 180 degrees and is equal to that of the crank when the angle between the crank and the bar 26 is either 90 or 270 degrees. To make the harmonic motion of the bar 17 periodic, the slot 27 is bounded by a surface 28 centrally above the bar 26 of a radius equal to, or as near as possible, the distance of the center of the pin from the axis of the crank plus the radius of the pin, and the pin rolls over this surface without imparting any motion to the bar. The surface 28 is equal and opposite to the surface 28, and the bar is stationary whenever the pin rolls over this surface. The surfaces 29 and 29 are straight and the slot is of a uniform width approximately equal to the diameter of the pin, and when the pin rolls over these surfaces the bar moves in harmony with the crank. The harmonic motion of the bar is. thus made periodic.

The crank 12 is mounted on the shaft 9 in such a position relative to the teeth of the mutilated gear that, when the pin enters upon the surface 28, the mutilated gear begins to impart motion to its follower; the angle subtended by this surface is equal to the angle subtended by the toothed surface of the mutilated gear; the bar therefore remains stationary during one-sixth of the period of motion of the mutilated gear, during which interval the follower passes through a quadrant. The pin now enters the surface 29 and rolls over this surface during one-third of the period causing the bar to descend; it then enters upon the surface 28 and rolls over this surface during one-sixth of the period causing the bar to remain stationary and then enters the surface 29 causing the bar to ascend during the remaining one-third of the period, thus completing a cycle.

In connection with my machine referred to above, the shaft 15 is revolubly supported on the post 16 by a bracket 30 provided with bearings 31, 31 for the driving shaft 9. On the bar 17 is mounted a bar 32, which is pivoted on a link 33, pivotally connecting a lever 35 carrying a weight 43 1 with a sleeve 36 slidingly mounted on the shaft 15, which is free to revolve therein. On the shaft 15 and above the sleeve 36 is mounted a sleeve 37, which is constrained to revolve with said shaft and free to slide thereon with the sleeve 36. The sleeve 37 carries trays 38 on which are mounted crates of bottles 39. The shaft 1 mounted in bearings 4:0, is driven by a belt 11, in the direction of the arrow, a belt shifter 12 shifting the belt from the loose pulley 2 to the tight pulley 3. The motion is transmitted to the driving shaft 9, through the intermediate shaft 6, by means of gears mounted on the shafts.

In the position shown in Fig. 5 a tray in the position marked A is about to be moved to the position marked B. The teeth of the gear 10 engage the teeth of the gear 14: and the shaft 15 revolves and takes along the sleeve 37. The sleeve 36 is held by the link 33 on which is pivoted the bar 32 mounted on the slotted bar 17 The crank 12 revolves with the shaft 9 and the pin 13 rolls over the surface 28 of the bar 17. As soon as the tray reaches the position B the smooth surface of the gear 10 rolls over the smooth surface of the gear 11 and the shaft 15 remains stationary. The pin 13 then enters the surface 29 of the bar 17 causing it to descend, and the sleeve 36 slides down followed by the sleeve 37, causing the trays to descend. The pin 13 then enters upon the surface 28 and while it rolls over the said surface the sleeves remain stationary, because the smooth surface of the gear 10 is still rolling over a smooth surface of the gear 1 1. The pin then enters the surface 29 and the sleeve 36 is caused to ascend taking along the sleeve 37 which slides on the shaft 15, said shaft being stationary as the smooth surface of the gear 10 is still roll ing over the smooth surface of.the gear 1 1. The cycle is completed when the pin 13 arrives at the end of the surface 29, when the teeth of the gear 10 are just about to become engaged with the teeth of the gear 14:, ready to enter upon a new cycle.

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