To all whom 'itmay concern: Be it known that I, EDMUND S. Cannon, a citizen of the United -States, residing at Dayton, in the county of Montgomery and State of Ohio,-h'ave invented certain new and useful. Improvements in Cash-Registers, of which I declarethe following to be a'full, clear, and exact description.

This invention is an improvement of that type of cash registerdescribed in Letters Patent of the United States, No. 7 51,611 issued to Thomas Carroll, Feb. 9, 1904:.

The main objects of this invention are; to provide an improved mechanism ,for adjusting the registering racksto particular oper ative positions; to provide an improved means for locklng the racks 1n any of such pos1t1ons; to provide lmproved means for controlling spring .actuated indicating mechanism.

' With these and-incidental objects in view,l

the invention consists in certain novel features of construction and combination of parts, the essential elements of. which are-set forth in appended claims and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification.

, Of said drawings: Figure'l is a vertical transverse section, drawer being omitted. Fig. 2 is a detail fof the flash. Fig. 3 is a detail of the camwhich segments and their corresponding racks to their in tial positions and second, for compressing the springs which operate the seg-' ments. Fig. 4: is a; detail of. the cam which by its .connection to the key detent-strip releases depressed keys at the end of each complete revolution of the operating handle. Fig. 5 is a detail of the, cam and detent which lock theracks in any posltion to which they are set.

The cams'illustrated in Figs. 2, 3, 4: and 5 are shown in the relative positions which the casing and cash first, for returning the the machine;

however, been substitutedior the operatin levers ofthe Carroll 'ro, rim na'rxonatpcas'n anersrna' mconrona'rnn IN 1 06.),-

device and a noveltcons'truction used for setting the racks. This" .consists' of spring pressed segment gears! inmesh with the racks and cam-s which set and. release the segments'and also compress the springs'by which. the segments are. actuated, regardless of any movement of the .segment.- j But one bank of .keys and the mechanism'operated' thereby is shown in the drawings. In the actual machine this bank of keys and the mechanism is duplicated several-time's, v.

In the device shown in the drawings the frame 1 has" journaled therein the *shaft 2 extending longitudinally through the-ma chine. The operating crank 55 shown. by dotted lines in the shaft 2. Rigid upon this'shaft' are the cams 3; 4, 5, 6, 7. and 8. 'The cams' 3, and 42 shown in Fig. 1 operate. the registering mechanism. .The registering mechanism IS 770 Fig. 1' is. rigidly secured 130 adapted to bemoved'first, toward the rack bar 9, so thatuthe counterpinions; 43 will ,come into the plane of the rack teeth 10,

second, downwardly over said racks, outwardly for .,"throwing the,.-pinions' out third,'.

of mesh with the rack teeth, and *finally returned to its-initial position as shown in 1, the amount wh'ich the counter is turned beingdependent uponthe position of the racks.

The register wheels 44' are mounted in the frame 11,,- while the frame 11 isslidably mounted in a swingingv frame 12. The frame 12, which is pivoted at 13% is moved toward and away from the racks '9 by the link 13, which is provided with an anti-friction roller 14 whichprojects into thecam groove 15. The cam groove 15 is "so formed with respect to-the center of the shaft 2 as.

to swing the frame 12 toward the racks and hold it in that position until the counter has passed down over the racks, then to return the frame to its'outer position and thereby disengage the counter pinions racks. I

The vertical movement of the counteris effected by the lever 16 which is pivoted at its rear end to a fixed bracket 17 and is pro vided withfia roller 18 which projects into the cam groove .19. Themovement of this lever is so'timed as to draw the counter down ,over the racks while thecounter'pinions are in posit-ionto engage therack teeth and toretu-rn the same after have been disengaged .fromthe racks.

from the The keys are slidable in the frame of the machine and when depressed will project into the path of a dog 21, which is mounted on a rocking segment gear 22, loosely mounted on the shaft 23. A spring 24 urges the segment toward the left of Fig. 1 but is normally prevented from doing so by the detent 26 and the plunger 27. The spring 24 is coiled around a curved rod and is compressed between the head 46 of said. rod and a lug 4'2, fixed to the segment gear 22. The rod 45 is slidahle in said lug and is secured at 48 to a. lever 49. Theopposite end of the lever 49 is connected by a link to' a lever 51 (see Fig. pivoted at 52 and provided with a roller 53 which projects into a cam groove 54. It will be seen from the form of the cam groove 54, that upon startingsto rotate the operating crank in the direction of the arrow 56, the lever 49 coming in contact with the lug 47 will move the segment 22 to its Zero position provided the segment has been released in the last preceding operation of, the machine. then be held in its zero position if no key has been depressed by the detent 26.. In case a key has beende pressed, the detent 26 would be swung out of its engaging position and the segment would immediately swing back under the pressure of the spring 24 until stopped by thedepressed key.

The bank of keys is provided with a detent plate 28 which is moved upwardly to swing the detent 26 out of engagement with the dog 21, by the depression of any key of the bank. The upward movement of the plate 28 is efiected by one of the pins 29 extending from the shank of each key coming in contact with one of the inclined surfaces 30 on said detent plate. The pins 29 also cooperate with notches 31 in the detent plate, for the purpose of retaining depressedkeys in such position until the shaft 2 has been caused to make one complete revolution. A

release key 36 is provided for each bank for the purpose of releasing any key that has been depressed by mistake to which end a pin 41 on the release key is adapted to enter an inclined slot in plate28 to lift the'plate out of engagement with a depressed value key. As the upward movement ofthe plate v 28 upon the depressionof any key causes the detent 26 to be swung out of engagement with the dog 21, and as it is desirable upon the depression of the release key to retain said dog in its upper position, a detent- 87 is provided for so doing. The detent 37 is forced into engagement with the dog 21 by the shoulder 38 on a plate 39, provided with a cam slot 40 which co-acts with the pin'- 41 on the release key 36. The detent 37 is normally held out of engagement with the dog 2lib y a spring 37 The construction and arra gement is such that detent 26 is normally in engagement with dog 21 while It will plished by the release key 36 or releasing lever 42, while detent 37 is rocked into engagement by the depression of release key 36 but only remains in engagement while the release key is held depressed.

The keys are released at the end of each operation of the machine by the cam action illustrated in Fig. 4, the lever 42 lifting the detent strip 28.

Each rack 9 is provided with. a notched alining plate 32, co-acting with the plunger 27 which is engaged with and disengaged from the alining plate by the device shown in Fig. 5, the spring 33 tending to withdraw the plunger from engagement but being prevented heat so doing by the cam 6, except during the time in which the racks are being restored and set.

The flash 34 is immediately drawn over the exposed indicators at the starting of the operating crank by the spring 34. lease of the spring 34 is effected by'the roller 35 being drawn into the cut away portion of the cam 7, as will be understood from Fig. 2 of the drawings. The cam 7 returns the flash 34 to normal position at the end of-each operation.

The re- 4 The indicator drum 57 is jou'rnaled on the shaft Revoluble with and secured to the indicator drum is a pinion 59 which meshes with the teeth 60 of the rack 9.

The operation of the machine is as follows By depressing one of the keys 20 the detent 26 will, be thrown out of engagement with the dog 21 as has already been de scribed. The shaft 2 is then caused to make one revolution.- The cams act so as to first release the flash 34 and withdraw the plunger 27 from engagement with the alining plate 32 and return the segment 22 to its Zero position by means of the lever 49 which is immediately returned to its initial position and followed. by the segment 22 which is thrown forward under the action of the spring 24 until stopped by the depressed key. By this movement of the segment 22, in mesh with the rack 9, the rack 9.v will simultaneously set the indicator to the proper numeral and bring a certain number of teeth 10 into position to be engaged by the counter pinions, Immediately after the rack 9 has been set, the plunger 27 is again forced into engagement with the alining plate 32 and locks the rack. The register is now brought down its constant distance causing the pinions 43 to be engaged by the rack teeth 10 and turned an amount which corresponds to the number of rack teeth which have been moved into the path of the register, and then moved out of engagement with the rack and returned to the starting position. Finally, before the machine comes to rest, the lever 42 is rocked, throwing the detent. plate 28 out of engagement with the de ressed key.

' v ,ncase the operating crank is turned when no key has been depressed, the segment 22 would merely be returned to its upper position and retained by the detent 26 in such position so that no registration would be effected.

The plungers 27 are so positioned relatively' to the notches on alining bar 32, that the, alining movement of the plungers slightly depresses rack bar 9, or in other words, the keys will stop the bar 9 so that the bottom of the notch in bar 32 opposite plunger 27 is slightly above the center of the plungers. The objects of this construction is to slightly raise the dog 21 away from the key'so that there is less friction on said key and a light returning spring will be suificient.

While the form ofmechanism here shown and described, is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown, for it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.
