To /LZZ whom zt may concern:

Be it known that l, HENRY GoLDMAN,a citi- Zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful lmprovements in Oalculating-Machiues, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part hereof, and in which- Figure l shows a nunlerating-wheel for a calculating-machine as seen from the righthand side of the structure, the shaft thereof being in end section and the construction of the opposite side shown in broken lines, and a fragment of the actuating-chain- Fig. 2 shows Fig. l on its reverse side with the mechanism before it on the shaft in Fig. l in broken lines. Fig. 3 shows the wheel Fig. l in central longitudinal section, taken on the plane 'y y, looking in the direction of the arrow, and on a fragment of its shaft. Fig. 4 shows the right-hand end of a shaft with two numerating-wheels, a fragment of the right-hand side of the case, the resettingwheel, and its stop mechanism. Fig. 5 shows a fragment of a septum placed between any two numerating-wheels, an end section of the shaft, the notched hole in the septum, and the resetting-cam, a spring-pawl, and a fragment of a numerating-wheel in broken outlines. Fig. 6 shows a fragment of the septum shown in Fig. 5 with the spring-pawl advanced to the position where it releases the tooth shown caught in Fig. 5. Fig. 7 shows a resetting-cam. Fig. 8 shows a sleeve in end view. Fig. 9 shows the spring of the stop mechanism and its push-button on the side of a fragment of the case. Fig. lO shows the working end of the stop-bar.

Like letters of reference denote like parts.

The objectof my invention is to improve the construction of the mechanism in count ing and calculating machines and numbering devices and to make it more easy and simple of construction and reliable in operation and more compact in its arrangement of its several parts. To attain said desirable end, l construct my said new mechanism in substantially the following manner, namely:

Each nu meratiug-wheel b is provided on the side nearest toward the lntnd-wheel or resetting-wheel m with a set of ten teeth c, in a cavity or recess ofthe side of the wheel,which point in a direction opposite to their corresponding exterior teeth, and on the opposite side of each wheel-t'. e., farthest from the hand-wheel m-is a corresponding recess c', within which are a pair of spring-actuated pawls yn o, whereof the former is so connected with its spring n' as to have its free end, with its transverse spur n2, pushed outward centrifugal to the axle a, while the spur o2 on the free end of the pawl o is pushed inward centripetal to the axle d. Said transverse spurs n2 o2 move upon the edges of the hole or cam (Z3 iu the septum or septums d and outer edge ol' the notched cam e, respectively. rlhe cam c is of about the same thickness as the septum d and is placed in the same plane. Therefore it is in the opening of the septum bounded by the periphery Said caln has a spur c2, which' iits into a groove a of Jthe axle a., whereby it turns with said axle. It also hasl a notch e', and all spurs e2 and notches c' are in like places, radially, thus placing the notches e' of a series of cams ein a line parallel to the axis of the shaft c. All cams d3 have notches d', which are in a line parallel to the shaft (t. The first or righthand wheel Z; of any series has no right-hand or near cavity; but the one next to it has such right-hand cavity, with teeth c, while the first wheel has a left-hand cavity, with the pawls n and o, whereof the spur n2 of the pawl n reaches over and engages with one of the teeth c whenever the wheel which carries the pawl 'n has brought it into the notch d, the only place in the cam d3 where the spur n2 can go ont to engage the teeth c of the next adjoining wheel to its left. Said spur thereby moves said next wheel until the said spur n2 is again lii'ted out of the notch d', which is so shaped as to make such action easy and so as to move said wheel only one space corresponding to one exterior tooth of the wheel h. rlhe motion of the said wheel b is in the direction indicated by the arrows, which is contacted by the spur Z of the chain Z and driven thereby. Each succeeding wheel of the series to the left makes a tenth of a revolution to a complete revolution of its driving-WheelA In calculating-machines it becomes necessary to reset all the Wheels b to Zero or the starting-point for each new operation. To attain said end in this construction, a circular cam e, with a notch d, Whose shoulder faces the pawl o, is mounted on the shaft d, on which it is held from revolving by a spur e2, which fits into the groove a of the shaft d and which occupies the same plane as the septum d. To the right-hand end ofthe shaft a is attached a resetting or hand Wheel in, which has a notch t on its inner Jface to receive the end of a stop-rodj, thrown into said notch by a flat siring i, whose forked free end passes into the groove j, and thns lifts the stop into said notch 7o, and which when out of the notch presses against the smooth side of the hand-Wheel until itis thrown into said notch to stop the hand-Wheel. Said wheel is released by depressing said spring through pressure on the stud t2, said parts being attached to the side of the casing of the machine. The Wheels l) and. on move in the same direction, as indicated. Always, therefore, when the Wheels Z) are moved by the chain Z the pand-spur o2 passes over the notch e from its rear; but Whenever the hand-Wheel turns the shoulder or face of the notch c/ catches the spur o2, and thus causes the Wheel Z) to move with it. The spur o2 may be at rest in any one of its ten places when the notch e takes it, and thus a single revolution of the hand-Wheel m Will bring all the wheels I) to their zero or starting point.

The chamber containing the pawls n o extends from the hub to the outer circle b', under the base of the teeth. (Shown in Fig. l.) The chamber, which contains the interior teeth of the Wheel b, extends from the hub to the line of the teeth, as shown in Fig. 2.

To prevent the friction of the sides of the Wheels upon each other, the sleevefis made slightly longer than the thickness of the Wheels,and it also contacts with and holds the cams e in their true places and planes of revelution.

N hat l claim isl. The combination with numeratingceases fixed and rotating cams in pairs between said Wheels and a contripetally anda centrifugally acting pawl in the other of said chambers, counteracted by one of said cams, one of said pawls connecting With its next Wheel and the other with said rotating cam, substantially as a rotatable cam, said rotatable cam and numerating-wheel moving in only one and the same direction, and a stop for said cam, whereof a revolution resets the numeratingwheels to Zero, substantially as specified.

The combination With a revolving shaft, adjoining Wheels thereon,free from said shaft, each with a centripetally and a centrifugally acting pa\vl,one of said pawls spurred to reach the next wheel thereto7 of a revolving cam to actuate one paw] and means to connect said shaft and revolving cam, substantially as specified.

5. The combination with a revoluble shaft and independent revolnble Wheels thereon, centripetally and centrifugally acting pawls with means to actuate the next wheel and means to reset said wheels to zero, of camsin fixed positions to actuate said pawls, substantially as specified.

6. The combination with a revoluble shaft, and non-reversible toothed notation-wheels independently revoluble thereon and centripetally and centrifugally acting pawls with means to actuate the next Wheel and moans to reset said wheels to Zero, of cams in fixed positions 'to actuate said pawls, substantially as specified.
