REGISTERING DEVICE.

SPECIFICATION forming part of Letters Patent No. 615,779, dated December 13, 1898.

.application filed April 27, 1898. Serial No. 678,967. (No model.)

To all whom it may concern:

Be it known that I, J Esse ALEXANDER, of the city of New York, borough of Manhattan, in the county of New York and State of New York, have invented a new and Improved Registering Device, of which the following is afull, clear, and exact description.

This invention is a register adapted especially for application to type-writers, so as to show the number of folios written thereby. The register'is also applicable to all other purposes in-which it is desired to keep a consecutive count.

This speciiication is the disclosure of one form of my invention, while the claims deiine the actual scope of the invention.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similarl characters of reference indicate corresponding parts in all the figures.

Figure 1 is a face view ofthe invention. Fig. 2 is a sectional plan view substantially on the line 2 2 of Fig. 5. Fig. 3 is a sectional plan view substantially on the line 3 3 of Fig. 5. Fig. 4 is a transverse sectional view substantially on the line 4 4 oi' Fig. 2; and Fig. 5 is a View similar to Fig. 4, except that it shows the parts in different position.

The register has a circular' casing 6, in the top of which is placed a dial-face 7, covered by a transparent sheet 8. Three frame- posts 9, 10, and 1l are attached rigidly to the bottom of the casing 6 and serve to support rigidly within the casing a rectangularlyshaped frame-plate 12 by means of screws that enter the upper ends of the posts. Mounted to turn freely within kthe frame-plate 12 and extending through the dial 7 is a hollow shaft 13, the upper end of which projects above the dial 7 and has two nuts 14E screwed thereon. Between these nuts an indicator-hand 15 is held rmly, the hand 15 being located above the sheet S, so as to turn over the same and denote graduations on the dial 7. Loose within the hollow shaft 13 is a spindle 16, which has its lower end mounted loosely in the bottom of the casing (i and which has iis upper end projected above the hollow shaft 13 and provided with a thumb-wheel 17.

y Mounted loose ou the hollow shaft 13 is a ratchet-wheel 18, to which a number-card 19 is fixed by means of pins 20. The numbercard is provided with numbers on its face running from O to 1950, such numbers being visible individually through an opening2l in the dial 7. The dial 7 is provided with numbers running from l to 50. The hand 15 travels around the dial 7, and when fifty numbers have been registered on the dial 7 the card 19 is turned one degree, so as to change the number that is visible through the opening 2l. The numbers on the card 19 are increased in a ratio of fifty, so that for each round trip of the hand l5 the card 19 is turned to change the number that is visible through the opening 21. The sum of the in dicator is thus shown by the number that is visible through the opening 21 plus the num ber that is shown by the hand 15 on the dial 7. A helical spring 22 is fixed to the ratchetwheel18 and also to the frame-plate 12. This spring 22 serves to return the ratchet-wheel 18 to its normal or zero position.

Mounted in the frame-plate 12 and in the bottom of the casing 6 is a revoluble and slidable spindle 23, provided with a ratchet-wheel 24 at its upper end, such wheel being held normally engaged with the wheel 18 by means of a bow-spring 25, which has its ends bearing on the bottom of the casing G and which engages a disk 27, fast on the lower portion of the spindle 23 within the casing G. The ratchet-wheel 24 is pressed by a spring-pawl 29, which serves to prevent the idle movement of the ratchet-wheel and which is carried fast on the post 9. Secured to the spindle 1G, so as to slide and turn therewith, is a ratchet-wheel 30,which is pressed by a springpawl 81, adapted to prevent idle movement thereof, and which is engaged at its under face by a bow-spring 32, that serves to hold the wheel 30, with its spindle 1G, normally in raised position, as shown in Fig. at. The ratchet-wheel SO bears down on the disk 27 and is movable with the spindle 1G, so that when the spindle is pushed down,ras shown in Fig. 5, the spindle 23 is also pushed down and the ratchet-wheel 24E is disengaged from the ratchet-wheel 1S. When this occurs the spring 22 returns the ratchet-wheel 1S to its normal or zero position. i0 is the prime mover of the indicator and is driven by a thrust-pawl which engages the teeth of the ratchet-wheel and which is IOO carried on a lever 34, fnlcrumed to the bottom of the casing G and projecting through an orifice 35 in one side wall thereof, so that the lever may be operated from the outside ot' the casing. The lever 34 is held in normal position by a retractile spiral spring 36. A leaf-spring 37, carried by the post'll, presses against the pawl 33 to hold the same at its work.

Fast to or forming part of the lowerfend of the hollow shaft 13 is a disk; 38, which has on its periphery a single tooth 39 and which also has directly adjacent to said tooth 39 a downwardly-projecting pin 40, located at the periphery of the disk 38. The pin 40 normally engages with the teeth of the ratchet wheel or disk 30 as said disk is pressed upward by the spring 32, and the single tooth 39 of the disk 38 is adapted once in each revolution ot' the disk 38 to engage with the ratchet wheel or disk 28, fast to the spindle Loose on the hollow shaft 13 and lying directly beneath the frame-plate 12 is a disk 41, between which and the disk 38 is located a helical spring 42, such sprin g havin g its ends iixechrespectively, to the disks 38 and 41. Pivoted on a pin 43, carried by the frame-plate 1l, and projecting downwardly therefrom is a pawl 44, which has a laterally-bent end 45, pressed on the periphery of the disk 41 by means of a spring 4G. The disk 41 is provided with a single tooth 47, adapted to be engaged by the end 45 of the pawl 44. Fixed to and projecting upwardly from the disk 38, adjacent to the periphery thereof, is a pin 48,which is adapted to engage the curved inner edge of the pawl 44 and to throw said pawl outward, so that it will release the single tooth 47 of the disk 41.

Having thus described the construction of my invention, I will proceed to explain the operation thereof.

The indicator is operated by swinging the lever 34 on its fulcrum, which causes the pawl 33 to thrust against the teeth of the ratchet-disk 30. This drives the disk 30 with a step-by-step revolution. The disk 30, being normally raised to the position shown in Fig. 4, has the pin 4() of the disk 38 engaged with the teeth of the disk 30, so that the disk 38 is driven from the disk 30. The single tooth 39 of the disk 38 imparts a fragment of a revolution to the disk 28 at each revolution of the disk 38, and the disk 28 through the medium of the spindle 23 drives the disk 24, so that such disk or wheel 24, normally meshing with the teeth of the disk or wheel 18, drives the wheel 18, and therefore turns the card 19. The spindle 16 being fast to the disk 30 is turned by said disk, so that the hand 15 is moved around the dial 7. The pawl 44, normally enga-ging the tooth 47 of the disk 41, holds the disk 41 from turning, so that as the disk 38 turns the spring 42 is wound up. The spring 42 is kept wound by holding the disk 4l stationary until the pin 48, turning around with the disk 38, engages the curved inner edge of the pawl 44 and throws the pawl outward against the tension ot' its spring 4G, whereupon the single tooth 47 of the disk 41 is released and the disk permitted to turn with the spring 42, which spring unwinds, the 'disk 41 turning a complete revolution, Meanwhile the pin 48 passes the pawl 44 and permits the pawl to return to its normal position, so that as the single tooth 47 of the disk 41 returns it again engages the end 45 of the pawl 44 and the parts are adjusted for a second revolution of the disk 38. It will thus be seen that the spring 42 is wound and permitted to unwind once in every revolution of the disk 3 The disk 18, being turned by the action of the disk or wheel 24, serves to wind up the spring This wheel18 is released upon the downward movement of the disk or wheel 24, which, moving down with the parts 23 and 28, disengages the disk 18 and leaves the disk without support against the spring 22, whereupon the spring 22 unwinds and carries back with it the disk 18 to the normal or zero position of said disk. It will thus be seen that upon the movement of the lever 34 the hand 'l5 is carried around the dial 7 in a step-by-step or intermittent movement, each step being immediately incident to the movement of the lever 3 The movement of the disk 38 results immediately in the movement of the hand 15, and a complete revolution of this disk 38 results, by the action of the single tooth 39, in a fragment of a revolution of the disk 18, so that such disk is moved one space, equal to fty units of the sum indicated. This operation continues until it is desired to set the parts to the zero position for asecond count, which may be done by pushing down the spindle 1G. This permits the return of the disk 18, with its card 19, because the disk or wheel 24 disengages the disk or wheel 18, and it also permits the return of the hand 15, because the disk or wheel 30 moves down to disengage the pin 40 from the teeth of the wheel 30 and leaves, therefore, the disk 38 without support against the return movement of the spring 42, which spring thrusts the disk, and consequently the hand 15, back to the zeropoint on the dial 7. The disk 30 is not returned, but revolves continuously under the action of the pawl 33, since the pawl 31 is broad enough to be continually engaged with the disk 30,11otwitl1standing the up and down movements thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
