(Cl. 235-91) The invention is a simple and inexpensive counting device by which a t-ally may be kept. It is particularly useful to farmers, truck drivers and pieceworkers, and will be found to‘be gen erally useful in many other ?elds of industry in to a fastening element for the purpose of sus pending the. device on a wall. In the event that it is desired to secure the back plate by more than which it is desired to keep a tally or score. The device is equipped with a pull chain manu one fastening element, apertures M are provided at the lower corners of the back plate receptive ally operated to register a count. to fastening elements. The use of these additional A counting mechanism is contained within a casing and is actuated by a tripping mechanism when the chain is pulled. A salient feature of construction resides in pro viding a lug for suspending the casing on a wall, and disposing the pull chain so that the pull is taken directly on the lug without any tendency to cause the casing to wabble. The invention essentially consists of a counting mechanism in which a step by‘step rotation is imparted to an actuating ratchet wheel by a trip 20 dogcarried by a ‘quadrant operated by the pull chain. The invention also comprehends a reset ting mechanism comprising perforated dials manually turnable by a pick that for convenience is carried by the pull chain. Having brie?y recounted the nature of the in vention, reference is made to the accompanying drawing in which Figure 1 is a perspective view in which a part of the front wall is broken away to disclose a unit dial. Figure 2 is a view of the back of the case. Figure 3 is a vertical cross section taken on line 3—3 of Figure 2. Figure 4 is a vertical section through the full width of the casing and showing the mechanism therein, the tripping mechanism being depicted in retracted or normal position. Figure 5 is a similar but fragmentary view showing the tripping mechanism advanced by the pull chain. Like numerals of reference indicate correspond ing parts in each figure throughout the drawing. Referring to the accompanying drawing in which the preferred construction of the invention is illustrated, the numeral 6 generally denotes a 45 casing having a front wall 1, integral side walls 8 and a detachable back plate 9. The front wall contains three horizontal aligned apertures IE] constituting sights. The back plate enables access to be had to the interior of the casing and 50 is preferably detachably connected by prongs H inserted in apertures. The ends of the prongs may be bent over‘ to form a secure connection. It will of course be understood that other means may be resorted to for the purpose of attaching 55 the back plate, if so desired. The top of the back plate has an integral lug i2 upwardly extending and pierced as at $3 receptive apertures, however, is optional. Formed in the back plate is a suitable arrange ment of openings as at l5 which enable the mech 10' anism to be inspected and parts replaced when necessary. , The counting mechanism comprises a series of dials, preferably three in number, identi?ed at 15 i8, i1 and i 8 as shown, each of which. consists of a circular disc rotatively journalled in the casing in overlapping formation. Each dial bears digits from one to nine and a nought on its outer face which individually appear to view through the IO0 respective sights as the dial is rotated. The indicia may be suitably inscribed, such as by litho graphing or otherwise as is common in the art. The dial It represents units, the dial i'l tens and the dial l8 hundreds. The dials are positioned directly behind the front wall ‘I of the casing in order that their indicia may, be readily read through the sights aforementioned, which dials in the preferred construction of the invention are to be mounted upon ?xed stub shafts as at l9 by means of ‘a sleeve~like hub ‘21). Each hub turns with its dial and presents a long bearing surface that resists wear and tear. Each dial has a ratchet wheel 2! integral with or secured to its hub and provided with ten teeth. 35 The ratchet wheels are individually held against retrograde movement by resilient detents 22 'at~ tachedto the casing. The ratchet of the unit dial has a projection at one side in the form of a bent wire 23 that presents a tooth for turning the ratchet wheel of the tens dial a distance of one tooth in each revolution of the unit dial, similarly the ratchet wheel of the tens dial is provided with a tooth 24 for fractionally turning the third dial l8 each time it makes a complete revolution. The tripping mechanism comprises a quadrant 25 having a pair of spaced side plates attached to a hub 26 journalled on a ?xed stub shaft 27. The stub shaft is similar in construction to the stub shafts I9, all of which stub shafts may be constructed with a head at the front end and locked in place at the rear end by means of in serted wires as indicated at 28. The wires are arranged to preclude the shafts from turning. Such construction may of course be modified ac 55 2 cording to circumstances. 2,108,103 The quadrant is pro vided with a curved or circular wall 29 united with the aforesaid side plates and presenting an arcuate face substantially on an arc whose centre is common with the axis of the quadrant. A pull chain 39 is applied over the curved face of the quadrant and has its upper end attached thereto at 3| and extends downwardly through a member 32 providing a guide passage there 10 for. The chain extends'for a suitable distance below the casing and carries a pick 33 for the purpose of resetting the counting mechanism, as number of times to bring the nought into register with the respective aperture in the front wall of the casing. The tens dial is then re-set by in serting the pick 33 in one of the apertures 4| exposed through the respective slot in the casing and urging the dial forwardly in the direction of the arrow head. This operation is repeated a su?icient number of times to bring the nought into register with the respective casing sight. The hundreds dial is reset in a similar manner. What I claim is: l. The combination in a tally keeper, of a cas will be hereinafter explained. ‘The ?exible element 30, upon being pulled, 15 turns the quadrant about its axis imparting a ing including an apertured bottom wall, a ratchet wheel journalled in the casing for operating a counting mechanism, a quadrant in the casing fractional turn thereto. The quadrant carries a trip dog 34 pivoted on an axis extending between the upper parts of the side plates thereof and having its distal end inwardly curved as at 36 20 to engage the teeth of the unit ratchet wheel 2|. An arm 3? radially extends from the ‘trip dog below the ratchet wheel and composed of a pair of spaced side plates connected by a pivotally mounted hub, and a curved wall attached to the at its pivotal axis and is angularly disposed with respect of the length of the trip dog. This arm is connected to a tension spring 38, which in 25 turn is connected to a Wall of the casing. The spring not only functions to urge the trip dog into contact with the teeth of the ratchet wheel but also retracts the quadrant to its normal po sition following a pulling operation. Means are 30 provided to limit the oscillatory movement of the quadrant, which means consist of prolonging the side plates of the quadrant to compose ?ngers 39 adapted to abut a wall of the casing in the re tarded position. The members 39 thus are held 35 in abutment with the casing by the spring 3'! in the normal position of the quadrant and when the quadrant is advanced a forward limiting stop is provided by the engagement of the edge 43 of the curved part 29 which contacts the casing, as 40 shown in Figure 5. The quadrant has a move ment about its axis suf?cient to enable the trip dog to advance the unit ratchet wheel a distance of one tooth each time the chain is pulled. It will therefore be evident that when the tripping 45 mechanism has been actuated ten times, the unit dial will have made a complete revolution and the tens dial will have been turned a distance of one-tenth of a revolution. The re-setting mechanism comprises a series 50 of equally spaced circumferential apertures 4| arranged in the dials ll‘ and is in accordance with the spacing of the teeth of their ratchet wheels. Two adjacent apertures of each of these dials are accessible by means of arcuate slots 42 65 in the front wall of the casing, which slots ter minate preferably in an arrow head in order to indicate direction of movement. In re-setting the counting mechanism, the unit dial is ?rst turned to zero by pulling the chain a sufficient 10 side plates having an outer face on an arc of a circle whose centre is common with the hub axis, 20 said side plates being prolonged oppositely to the curved wall to present ?ngers for contact with the aforesaid bottom wall of the casing to serve as stops; 3. ?exible element trained over the said curved wall of the quadrant and secured at an 25 end thereto and extending through said aper tured bottom wall, a trip dog pivotally carried by the quadrant radially of its hub for engaging the teeth of the ratchet wheel, and a spring con nected to the trip dog such as to retain it in con 30 tact with the ratchet wheel and to retract the quadrant when actuated by the ?exible element. 2.
