7 Claims. (Cl. 273-49) This invention relates to ball elevating mechanism and more particularly to a rotating ball elevator for use with an automatic pinsetter. I

An object of this invention is to provide a improved ball elevating mechanism.

Another object of this invention is to provide a new and improved ball elevating mechanism wherein the balls are elevated by a ring-type rotating elevator.

A further object of the invention is to provide a ball elevating mechanism including a rotating annular member and a pair of vertically arcuate tracks having generally horizontal lower ends mounted within the periphery of the annular member whereby the annular member engages the underside of a ball and elevates it along the tracks to a discharge track.

Another object of the invention is to provide a ringtype rotating ball elevator extending across the alley pit for engaging a bowling ball and, in association with vertically arcuate tracks disposed within the periphery of the ball elevator, elevating the ball to a discharge track. Another object of the invention is to provide ball elevating mechanism in the form of a pair of verticallydisposed, spaced-apart, arcuately-shaped track members which are spaced from a ring-shaped or annular ball elevating member a distance slightly less than the diameter of a bowling ball and are positioned within the periph cry of the ball elevating member, one of said track members being disposed forwardly of the elevating member and the other track member being disposed rearwardly of the elevating member, the lower end of the track member disposed forwardly of the ball elevator being pivotally mounted in order to move vertically as a ball moves thereunder and to then return downwardly to a position wherein the ball is confined between the pair of track members and rests on the ball elevating member and may be elevated by the rotating ball elevating member.

The objects of the invention generally set forth, together with other ancillary advantages, are attained'by the construction and arrangement shown by way of illustration in the accompanying drawing, in which:

Fig. 1 is a perspective view in elevation of the ball and pin elevating mechanism as mounted in a bowling alley;

Fig. 2 is a perspective view in elevation of the mechanism shown in Fig. 1 with the ball elevating mechanism removed;

Fig. 3 is a fragmentary perspective view in elevation of the mechanism shown in Fig. 2 and particularly the mechanism for resetting the pin-engaging paddle members;

Fig. 4 is a vertical view in section of one of the pinengaging paddle members showing the latch mechanism for holding the paddle member in its extended pinengaging position; and,

Fig. 5 is a diagrammatic end view in elevation of the ball elevating mechanism showing a ball engaged between the annular ball-elevating member and the spacedapart track members looking toward the mechanism from the left-hand end of Fig. 1.

While this invention is susceptible of embodiment in new and Patented June 30, 1959 many different forms, there is shown in the drawings and will herein be described in detail an illustrative embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiment illustrated. The scope of the invention will be pointed out in the appended claims.

My improved pin and ball elevating mechanism may be mounted at the rear of a pit having side walls one of which is indicated at 1 and a pit floor formed of a plurality of moving belts 2, 3 and 4. Reference may be had to my co-pending application, Serial No. 2205, filed January 14, *1948, now Patent No. 2,729,449, granted January 3, 1956, for a complete disclosure as to the construction and drive for these belts. T-he belts 2 and 4 are moved in a manner whereby their upper reaches move toward the middle belt 3, the upperreac-h of which moves toward the rear of the pit. Thus, it will be seen that pins and a ball will be directed to the rear of the pit at a point or position approximately mid-way between the sides thereof.

As shown in Figs. 1 and 2, a vertically-disposed framework is formed from one set of connected channel members 5, 6, 7, 8, 9 and 10 which are interconnected with another set of connected channel members 11, 12, 13, 14, 15 and 16, the two sets of channel members being reenforced by cross members such as 17 and 18 and being interconnected by channel members 19, 20, 21 and 22. Rotatably mounted within the framework is a ball elevating mechanism which is in the form of a rotatably mounted ring-shaped or annular member 25 and a pair of cooperating arcuately-shaped, spaced-apart track members 26 and 27 which are vertically disposed and spaced apart from the annular member 25 a distance slightly less than the diameter of a bowling ball A.

The annular member 25 is driven by a belt 30 disposed about the outer periphery of the annular member and passing over a driving pulley 31. Guide rollers 32, 33, 3'4, and 35 mounted in the supporting framework function' to guide the annular member 25 for rotation and also to guide belt 30 on the periphery of the annular member. A weighted roller 36 is mounted on pivotal arms, one of them being shown at 37 and functions to maintain the belt 30 taut.

A- ball trap mechanism is provided to insure that a ball will be properly engaged by the track members 26 and 27 so as to ensure proper alignment of the ball with the annular member 25. This mechanism takes the form of pivotally mounting the lower end 38 ofthe track member 27 by means of a bracket 39 secured to asupport block 40 for the lower track end 38 and a hinge'member 41 connected to a central frame member 42. It will thus be seen that the lowermost position of the annular member 25 is adjacent the conveyor 3 which constitutes a ball pickup position. As a ball is moved onto the annular member 25, it will cause slight upward movement of the lower track end 38 to permit movement of the ball into engagement with the lower end 26a of the track member 26. As this occurs, the lower end 38 will lower slightly and the ball will be rolled up the track members 26 and 27 by clockwise rotation of the annular member 25 as shown in Fig. 1. A plurality of wires indicated generally at 45 secured to brackets 46, 47, 48 and 49 form aside guide to prevent accidental movement of a ball rearwardly of the track member 26. The upper ends of the track members 26 and 27 terminate in wires 50, 51 and 52 which form'a discharge track for receiving a ball and guiding it to a conventional return track, not shown.

The track member 27 is disposed forwardly of the ball advancing member 25 while the track member 26 is disposed rearwardly of the ball advancing member 25 at cdhtact bf anti-n1 member 25 with the ball A isat Tidiiitbetweiidhe points iiiade by Earlene? s v n by d i epu l T e n a im ber 60 jis,guided m plurality o f, guide rollers. 63,64, 65 and ;6' ..11Q tsdai t ame ork h re de l r as; fie .6 also i a t o Q-s r i t el AS then ninth: were t-b ndsuns t; ia-la h t ,As shown mgre clearly in Fig, 3, .the annular1 memben (60 is provided with a v rirn madeup of rim: parts 71 and 72, Ihe rim 72 is eta-slightly greater diameter than ha z pq nt a d t a s s v ra n i pul y 1 9- 1 2;

It is necessary to prevent interference between a paddle member 77 and the belt 100 as the paddle member is carried up betweenthebelts 100 and 101 so that a trip block 117 (Fig.4) is mounted on the frame-work adjacent the lower end of the belts 100 and 101 for tripbinstli1e ini m f fremi paddle m m 77 to' move toits radial position as shown infFigQ The trip block 117 is carried by a stationary portion of the framework and 1 is positioned-so asrto permit the paddle members 77 to effectively position succeeding pins between the belts 100 and-101, and to trip the latches 85 so that the paddle members move past the belts without conflict therewith.
