CALCULATING MACHINE.

Application filed January 28, 1920. Serial No. 354,568.

To all ILZLO'UZ- it may concern:

lie it known that I, Dononns TURNER, a citizen of the United States, residing at St. Louis and State of Missouri, have invented certain new and useful Improvements in Calculating Machines, of which the following is a. specification.

This invention relates to calculating machines and its general object is to produce a compact machine of simple construction which will present relatively large area for carrying the computations. The features of the invention are particularly applicable to that type of machine in which a pluralitv of indicating members or rollers are carried upon a movable carrier or cage, and one of the objects of my invention is to provide simple key-controlled means for bringing the cage into position to present any one of the indicating members opposite the reading point of the machine, at the same time rotating the indicating member so as to present the proper computation at the reading point, the computations on the indicating members being functions of the numbers carried by the keys. The machine is particularly adapted for performing multiplications and while it has a wide range of usefulness, it is expected to be especially useful in expediting th laborious work of making up payrolls from workmens time cards. where the workmen have different wagerates.

In the embodiment shown I have described a pay roll calculating mechanism which is constructed. for use with the so- Further objects of the invention will ap-- pear hereinafter.

The invention consists in the novel features and in the general combination of parts to be particularly described hereinafter, all of which contribute to produce The a simple and efficient calculating machine. A preferred embodiment of my invention will be particularly described in the following specification, while the broad scope of my invention will be pointed out in the appended claims.

Like numerals refer to like elements throughout the drawings. The machine comprises a base 1. and two banks of keys generally indicated'by numeral 2. The case 1 houses the mechanism and is provided with a sight opening permitting a view of the proper indicating cylinder. At the left side of the machine is provided a handle 5 in convenient reach oi the operator. A vertical board or rack 6 is located above the sight opening 3, the same comprising a plate 7 having); the metal strips or cleats 8 secured to the front "taco thereol see Fig. 1.7. These cleats or strips are so located as to accommodate a memo or time slip between each pair, the, indicating figures on the indie/a inn" cylinders being: correspondingly spaced so that, in effect; th space between each pair i cleats will accommodate the time slips of all ol the worlnnen working at a certain rate or ,z'neino slips hearing the name or number of each worlnnan working at that rate upon which may be noted the suc cessive indications made as a result oi? successive calculations over periods of t me for ,which the pay is to be ealcnlatedl have d signated by uuu'n ra} f), for ian'iple the space between a pair of cleats which is lo cated above the rate of r 4 1 per hour. ll itlnn the casing are provided a plurality of lfflCllCiltlDQ n'iei'nbers in the form of hori- Zontally disposed cylinders or rolls l0 carwed in a carrier or cage termed of two siiiders or end pieces ll. cored or apertured. at 11 for lightness see Fig. The spiders ll are carried by the shalt l2 which is journalled in ball llOtlYiIlQjS it; at either end, see Fig 11, these hearings being carried by suitable vertical frame plates or uprights H: and Located beneath the shaft is a second, horizontal shaft 16 to which attached the operating handle 5. I have provided mechanism to yieldinn'ly transmit rotation of the shaft to the shaft which consists o! a sector or segment 17 having suitable teeth termed upon its periphery. This segment is in mesh with a great or pinion l9 loosely mounted upon the shaft 12, This pinion is i ormed with a radial arm 23 provided with a nvotallv attached pawl which engages a ratchet wheel 21. rigid with the shaft 12. A spring 24 serves to maintain the pawl 22 in contact with the ratchet 21. The handle is provided with a pin extending through a slot in the upright 15. The segment 17 is provided witlra pin or stud ill. see Fig. 4;. and a coiled sprin 25) connects the pin 5 and the pin 1?. When the handle 5 is moved to the left in the operating stroke as viewed in Fig. 4-, the tension put upon I spring 535) will rotate the sesnnent 1? which will rotate the pinion 19 and radial arm 38. The latter by virtue of the engagement oi its pawl 22, will rotate the ratchet 21. and thereby the shaft 12, the rotation of which will rotate the spiders l carryingthe indicating cylinders. this movement being; for the purpose 0 t alining the proper roller beneath the sight opening 3, as will. be more fully described hereinafter.

Adjacent one extremity oi the shaft 16 attached an arm 25 to which is attached one end of a coiled sprin E26- the other end. thereot being sci-lured the casino at a suitable point indicated by numeral 21., see Figs.

p ications, are constructed so that they io ht as possible in order to eliminate is possible movement 0 the cage inomentuniu at the completion o'l' a V In the form shown in 1. for example the cylinders are l of li ht aluminum tubing" 30 y i a 0' tool or the like, indicated lnuneiais 3'1 and in each end thereof. The computations are printed upon thin paper and secured to the cylinders or rolls by any suitable adhesive The heads 31 and UK) on are provided with trunnions journalled in the soiders 11. ot the cage, as shown in Fig. 11. Secured to extremities ot these trunnions oi? the heads 31 are gears or pinions Rotatably mounted on the shaft 12 is a sleeve 3531 see Fig. 11, which carries a gear which is in mesh with all oi the pinions as. These gears are so constructed that the ratio between the teeth thereon will be an integer, such ratio being 2, 8, 4L 5, etc, as desired. in other words, a complete rotation ot the gear 34 will. result in an even number of rotations of the cylinders 10. tlecurc-d upon the sleeve 33 is a ratchet 2i (similar to the ratchet see Fig. 8 A radial arm i2 3, carrying the pawl 22 and a spring 24, is rotatably mounted on the Slltl'l t l2 and is formed with or secured to the pinion 20. A segment or sector is provided consisting; 01 a radial arm 18 having its toothed and curved portion 18 in mesh with the pinion 20 such sector being rotatably mounted upon the shaft 16. An operating arm 18 is provided. the same lying in back of the sector 18. as viewed in Fig. 8. This arm ltl is also provided with airangg ularlv disposed arm which is secured to the shall 1(3 and rotates therewith and is provided with the pin 18 to which one end of the coiled spring; 28 is attached the other end thereol being secured to a suitable pin 18" upon the sector 1-?" see] Fig. 8, so that rotation of the shaft 16 in an operating stroke out the handle 5 will move the rack 8 through the medium of sprii'ip E28 and thereby rotate the pinion 20. arm F23 and ratchet 2i" to rotate the sleeve 3 and gear 34. The purpose of this movement is to transmit rotation in one direction to the cylinders about their in dividual axes.

I provide key controlled means for positioning: the indicating members opposite the readi point, and tor controlling" their rotation on their axe This means w ll now he described. Rigziidly attached to the sleeve 1s a hank or series of notched discs 36 loo 1,47 ,sea

shown as ten in number, each of these discs having the properly located notch 37 in its periphery. A second bank or series of discs 38 is rigidly attached. to the shaft 12, these also being ten. in number in the form shown and being each provided with a properly lo cate d, notch.

The key hank consists of two series of ten keys arranged as shown in Fig. 1, for eX- ample, one set of keys representing tenths of hours, the other representing hours, each set of keys being numbered from zero to nine inclusive. The hour keys coact with the set of discs 38 while the tenth keys coact with the discs 36. I provide means including parts moving: with the cage, and parts moving: with the rollers 10, cooperatingr with the keys to stop the cage and also the rollers in predetermined positions. For this purpose a lock bar L extends from be- .neath each of the tenth keys 2, see Fig. 7 for example, and a lock bar 39 extends from heneath each of the hour keys 2'. Each. key is constructed with a head 41, see Figs. 13 and I5, and a shank or plunger 42 slidably mounted in the base 1 and in the horizontal bars 43, see Fig. 13. The lower part of each shank 42 is slotted as indicated by numeral 4%, see Fig. 14, to accommodate the end of the coact-inp; lock bar 39 or 40, lock bars 39 being curved or off-set to pass beneath bars without interference, see Fig. 7 for example. A washer 49 is slidably mounted upon each of the shanks 4.2 and rests upon the end of the coacting locking bar, as shown in Fig. 13. Secured tothe shanks 42 are the collars 48 and a coiled spring 50 extends between each washer 49 and the corresponding collar 48. At the upper end of the shanks are provided washers 16 and coiled springs 45 extend therebetween and the bars 43, these springs serving to normally maintain the keys in undepressed position. The lockingr bars 39 and 40 are pivoted upon the rod 4:0. see Fig. 7.

Placed longitudinally one for each bank of keys 2, 2 are two series of locking pawls 51. each. provided with upward engaging ends which, when. the keys are depressed, will slip over the collars 48 into engagement therewith, as shown, for example, at the right hand of Fig. 13. Coiled springs 53 coact with each set of locking pawls to normally maintain. them in position to engage the collars 48. Since each set of pawls operates as a unit, it would be obvious that, should the wrong key in a horizontal bank be depressed, depression immediately thereafter of the proper key will operateto release the previously depressed key prior to retention in depressed position of the latter depressed key. A longitudinal release bar 54 is provided to release all of the keys simultaneously, the two sets of pawls being operatively connected by a link 55, which is slotted at 55 to permit independent actuations of the pawls during calculation operation.

The locking bars 39 and ll) have their outer extremities adjacent the peripl'ieries of the discs 36 and 38 and depression of a key will exert a yielding pressure upon one end of a locking bar to bring its other end into contact with a corresponding disc, which will be permitted to rotate until the notch therein alines itself with the end of the lock in; bar, the yieldingpressure upon which will ensure engagement or entrance of the end of the locking" bar into such notch, therel y locking the disc against further movement.

To assist the operator in the determination of his calculations, especially where the majority of the same are made on a basis of one rate, I provide a framing device slidably mounted upon the rod 61 adjacent to the sight opening 3, see Fig. 1, this framing device being so constructed as to embrace the unit rate and the opening therebeneath in which the calculation at that rate is to be located.

In the operation of the machine. assuming, for example, that the time slip shows an employee to have worked 3.8 hours in one day at 30 per hour, the key operating the numeral 3 in the hours bank is depressed as is the key bearing the numeral 8 in the tenths bank. Thereafter the handle 5 is pulled toward the operator and the racks l7 and 18 are thereby rotated until the lock bars 39 and 4:0, corresponding to the dcpressed hours and tenths keys, engage with their corresponding discs 38 and 36. It will be understood that the notches in the discs are properly located in such manner that rotation of the shafts 12 will be permitted to aline that cylinder beneath the sight opening 3 which corresponds to the numeral depressed in the hours bank and UIOVGIUGTlt of the sleeve 33 will be effected which will rotate such cylinder onv its axis through the medium of gears Sat and 35 an amount sufficient to aline the proper set of numerals on such roll or cylinder beneath the sight opening 3. In other words, the indication beneath the sight opening: is the result of two movements,one the rotation of the cage about the axis of shaft 12 to locate the proper cylinder beneath the sight opening and the other the rotation of such cylinder about its own an amount sufiicient to aline the setof numerals corresponding to the depressed tenths key beneath such openina'. Should the relation ofihe notches and locking" bars be such that. for example. the locking bar 39 is engaged with one of the discs 38 prior to the engagement of the ac tuated locking bar 4th with one of the discs,

36, it will be apparent that movement of the shaft 12 wlll cease, but the operating lever 5 may continue its operati strolce due to the provision of the sprii'iy; 29, as will be apparent. In the example given. where numeral key 3 ot the hours keys and numeral key 8 of the tenths keys have been depi' sod, the cylinder representing third set of figures will more during actuation ot the operating handle 5 unt'l alined beneath the opening 3 and such cyl nder will be rotated until the set ot figures representing: 0'. an hour thereon are alined at rest beneath the sight opening 53, utter v-rhich the operator will note the product on the memo slip in the superimposed rack and, will proceed to obtain the nets calculation.

In the tlJOVO it will be seen that the roller or cylinder ot the set carries the 4 culations at from one-tenth of an hour t nine-tenths of an hour, a row of blanks l1 ing left representing zero-tenths indication. The second cylii'ider will bear the calculations for one hour to 1.9 hours and so on.

It is to he noted that with the mechanism described, where calculation for an even hour is to be made, not only is the proper hour key depressed, but the zero key ot' the tenths set is also depre 'od, Similarl where the total tor a traction of an hour is to he obtained, the zero hours key is do pressed in addition to the proper tenths trey.

It will be obvious that, while 1 have de scribed and illustrated a machine intended to calculate according to the International time system, the sets of figures may be varied to accord with any requirements where the use of a single multiplier and multiplicand involved. In Fig. tor example, i have illustrated a removable thimble (33 hearing the desired indications, which may be slipped upon the cylinder 63, the thimble having the tongue 62 slidable in the groove 63" to ensure proper positionim': oi the thimblc. This construction permits ready replacement ot calculatin5;- thimblcs, it desired.
