UNITED STATES PATENT OFFICE BESETTING MEANS FOR A TOTALIZER Herman F. Sadgebury, Dayton, Ohio, assignor, by mesne assignments, to Central United National Bank, Cleveland, Ohio, as trustee Application July 17, 1931, Serial No. 551,507 8 Claims. (01. 235-430) This invention relates to a resetting means for a pin 55 which is received by an arm 56 rotata totalizer. In certain totalizers, such as that ably mounted on the shaft 54.

The lever 53 carries rotation of a long tooth or lug 96, which is the ll carrying tooth. The carrying teeth are so positioned on the sides of the totalizer pinions 3 that they will engage the pawls 67 as soon as the totalizer pinions 3 pass beyond the position in which they would be when set to represent the numeral nine. It will, of course, be understood that there is one such carrying tooth on each totalizer pinion. As the lobe 5 passes beyond the roller 46, the roller rides on the periphery of the cam 43 and the spring 74 moves the lever 44 slightly to the left as viewed in Figure 7, which partially lowers the holding member 57 in a position such that its left hand end, as viewed in Figure 6, will be slightly below the carrying levers 47. If any one of the carrying teeth 96 should not engage its tripping pawl 67, it would move the pawl to the right as viewed in Figure 6 disengaging the laterally extending lug 63 from the notch 68 and the spring 69 would pull the carrying lever 47 downwardly until it was stopped by the holding member 57. when the shaft 4 has practically completed its revolution the roller 46 will roll off the cam 43 and the spring 74 will move the lever 44 to the left as viewed in Figure 7 and lower the holding member 57 to the position shown in Figure 6 so that the carrying dog 60 will engage the totalizer pinion of next higher order and rotate it one notch.
The cam 42 engages a roller 73 rotatably mounted on a pin 72 carried by a bell crank lever 71 which is pivoted on the shaft 45. The lever 71 is urged to the left, as viewed in Figure 7, by means of a spring 75. This lever carries a pin 76 at its outermost upper end, which pin is connected to a pin 77 on a crank lever 78 by means of a spring 79. The crank lever 78 is secured to a shaft 80, which shaft carries a plurality of crank arms 81 which are bifurcated at their upper ends and receive the shaft 27 carried by the frame members 25.' It will be noted that the roller 73 does not engage the cam 42 until some little time after the cam 43 has engaged the roller 46. The object of this construction is to give the cam 43 suflicient time to elevate the carrying levers 47 and for the spring 69 to move the holding member 57 slightly downwardly after the roller 46 has passed the lobe 5 and for the cam 42 to then engage the roller 73 and rock the crank arms 81 inwardly or counterclockwise as viewed in Figures 7 and 1 so as to move the totalizer frame to the left as viewed in Figure 1 so as to engage the totalizer pinions with the differential gears 1, this movement being permitted by the slots 33 in the fixed frame 28, which slots engage the guide shaft 31. At approximately 180 degrees thereafter the cam 42 passes beyond the roller 73 and the spring moves the totalizer frame and totalizer pinions to the right as viewed in Figure 1 so that the subtracting movement of the differential gears 1 will not be imparted to the totalizer pinions.
With the parts in the position shown in Figure 6 it is obvious that if I attempted to rotate the resetting shaft 6 on which the totalizer pinions are mounted in a clockwise direction so that the spring pressed resetting pawl 7 would engage the resetting notch 8, the totalizer pinion could not be moved because one of the teeth would be in engagement with the notch 62 which would lock it against such movement. It is, therefore, necessary to elevate the carrying lever 47 so as to disengage it from looking engagement with its totalizer pinion. I provide a key actuated shaft 9 with a square end 10 which is adapted to receive a resetting key of conventional design. This shaft is mounted in bearings 11 carried by the frame 28 and the shaft is provided with a bevelled gear 12 which meshes with a bevelled gear 13 mounted on a sleeve 14 provided with a groove 15 which receives a tongue 16 on a sleeve 17 which carries a cam 18. The sleeves 14 and 17 are loosely mounted on the resetting shaft 6, which shaft carries a pin 19 which extends through slots 20 in the sleeve 17. The shaft 6 has secured thereto a locking disk 21 provided with a notch 22. A pawl 23 actuated by a spring 60 is provided with a pawl nose 24 which normally extends within the notch 22 and into the deepest part of the cam 18 as at the point 26. The pawl is mounted on the shaft 54 and is provided with a cam surface 30 which engages the pin 55, which, it will be remembered, is attached to the arm 56 connected to the holding member 57.
When the operator engages the square end 10 of the key actuated shaft 9 with the key and rotates the key, he thereby rotates the bevelled gears l2 and 13, sleeves 14 and 16 and cam 18 and the nose 24 of the pawl 23 rides upwardly from the point 26, which is the lowest portion of the cam 18, up on the periphery of the cam, the said cam rotating in the direction of the arrow shown in Figure 4. This elevates the pawl and by means of the cam surface 30 and pin 55, the holding member 57 is elevated, which raises the carrying lever 47 out of engagement with the totalizer wheels. This motion of the sleeve 17 is not imparted to the resetting shaft 6 until the pin 19 reaches the end of the slot 20, and thereafter the resetting shaft 6 rotates with the sleeve 17 and the resetting pawl 7 engages the resetting notch 8 of each totalizer wheel, rotating them to their zero position. Just after they pass their nine position, thenose 24 of the pawl 23 reaches the notch 22 of the locking disk 21 and is forced into said notch by spring pressure, striking the cam 16 at approximately the point 32 on the inclined or acting surface of the cam, rotating the sleeve 17 in a direction reverse to the arrow shown in Figure 4, so that the pin 19 will again lie in the right hand end of the slot 20, which permits the holding member 57 to drop into the position shown in Figure 6 and allows the carrying dog 60 to descend into the position shown in the said Figure 6. This would, of course, tend to rotate the wheels to perform a carrying operation but this tendency is completely off-set by the fact that the pawl 7 is going to complete the rotation of the totalizer pinions one step further anyhow so that all of the totalizer pinions would be set to zero.
In my construction it is, therefore, not necessary to provide any lever or other means to elevate the holding member 57 and carrying lever 47, but the entire resetting operation is performed by simply rotating the shaft 9.
I realize that various changes may be made in the specific form of the invention as shown and described herein and I, therefore, wish to reserve the right to make such changes as may fairly fall within the scope of the appended claims.
Having now described my invention, I claim:
