Muir-REGISTERING MACHINE.

Application filed February 23, 1909. Serial No. 29,958.

To allwhom it may concern: v Be it known that 1, CHARLES l1. SNYDER, a .citizen of the United States, and resident of Camillus, in the countyof ()nonda'gadn the State of New York, have invented new and useful Improvements in Milk-Registering Machines, of which the'following, taken in connection with the accompanying drawings,

milk-dealer's and purchaser s, which is a very unsanitary practice, it being ,well known that, in many instances persons have acquired the habit of placing the tickets in the milk-receptacle, which of course is most objectionable;

The present invention consists in .the novel arrangement and combination of the compo nent parts of the registering-machine here.- inafter fully described and claimed.

In the accompanying drawings Figure 1 is a front elevationof the milk-registering machine embodying my invention, a portion of the inclosing case being broken away; Fig.2 is an elevation with the front of the case and dial-wheels removed to show the mechanisms-which actuate said'wheels; and,

Fig. 3 is a horizontal sectional view of the inclosing-case showingmoreclearly the are ra-ngementof the parts of the machine.

Like characters. of reference indicate like parts in the several views.

-A- denotes an. upright rectangular- .shaped case in which the registering-mechanlsms are inclosed. Said case is preferably formed of sheet metal and is provided with.

a removable front-wall 'A fastenedin place by means of screws -B-B or otherwise. This case is designed to be attached to any suitable and-convenient support by means. of screws or other fastening devices, or. the screws B- B may serve for the pur ose.

. e registering-mechanism comprises essentially two upright dial-wheels or disks -1 -1 each provided on its front face with Specification of Letters Patent.

: numerals, those of one wheel being arranged to be broughtto view, one at a time at an open1ng.-2 in the front-wall of the case,

and thoseoftlie other wheelarranged to be brought to view at a like opening --2 in said front wall. These wheels may be so numbered as to adapt the machine to registeralmost any amount or amounts. However fo1. al] practical purposes, the-numbering shown will sufiice for a clear understanding of the machine, the wheel 1 bearing 'zer o 1', 2, '3, 4:, 5, 7, 8, 9, and the other wheel -1, bearing zero, 10, 20, 30, 40, 50,

60, 70, 80, 90, the latter wheel adapted to be turned to bring its numerals successively into registry with the opening -2" incident to the complete revolutions of the wheel 1, as will. be shortly more fully explained. Q

The wheel or disk -lis carried on the front of a ratchet-wheel -3 mounted loosely on a shaft 4' suitably journaled at its ends in the front and rear walls of the inclosing-case. To fasten said wheel 1- to the ratchet-wheel I prefer to provide the former with a square central opening which is fitted to a correspondingly. shaed hub -5- formed on the ratchet-wheel. he other so I wheel or disk 1" is supported on a ratchetwheel 6 by providing the f same with a square central. opening wh ch receives correspondingly shaped hulrof si'ratchet-wheel as indicated at 7-, and is thus rot'ated' by 'said ratchet-wheel, said ratchet-wheelbeing mounted loosely on a shaft ,-8-supporte at its ends in the front and rear walls of the i .case as shown in Fig. 2. Back of the aforesaid ratchet-wheel -3 is disposiid the-13amy astene to operating-wheel --9 suitab I the shaft -4 and provided with ratchetteeth "9 with, which a retaining-pawl -10+ normally engages to prevent the turning of the wheel --9 to'the left for the purpos'ehereinafter explained. The retaining-pawl 10- 's vpivoted to the rear wall of the case as indicated at -10 and is adapted to be thrown outuofi-engagement with the ratchet-wheel -9 by means ofa key --C.v inserted removably throu h a slot -D in the adjacentend wall of tie case, and formed with an offset which is shaped to engage aninclined flange -11--' ico I y .r

aretalnlng-pawl -lo which 1s formed on the pawl, whereby the latter is supported at one end'on a shaft cured at its ends in the front and rear walls projecting-h oft'the case. Said retaining pawl 15-. normally engages the wheel '3-- to prevent -movement of the dial-wheel leither by accident or tampering with the latter wheel through the opening '-2. This pawl -15 is actuated by an arm -17 pivotedat one end to the shaft16 and formed integral with or securely fastened to the pawl, as shown in Fig. 3, to the free end of which arm is pivoted a dog -18 adapted to be actuated by the'ratchet-wheel 9' for lifting the arm whereby the latter iscaused to throw the retaining-pawl .15 out of engagement with the ratchet-wheel -3, so as to release the wheel 3- and allow it to be turned for rotating the dialwheel .carried on said wheel -3-..

The dog '-l8 is formed with a depending lug l9 for engaging the teeth of the Wheel 9, and with a similar horizontally 20 which is disposed to engage an 0 set on the end of the .arm whereby the latter is" lifted when the wheel -19 is turned to the right-as clearly illustrated in Fig. 2. By this construction of the dog 18-. it is evident that the wheel 9- is turned to the left, the dog will move without lifting the arm l7.

The ratchet-wheel 6'is-provided with a retaining-pawl .2lpivotally supported on and depending from the shaft --l6- and is formed integral with or securely fastened to a depending lever -22 pivotally sup ported 'on said shaft and havin its lower or free end portion forined wit a curved offset 22 disposed in the path of the lug 23.- projecting from one of the teeth of the wheel -3-. The engagement of this lug 23' lifts the aforesaid pawl -2lou't of engagement with the ratchet-wheel --6, and when the pawl is' thus disengaged, the lug -23 engages one of the teeth of the wheel -6- and turns the latter whereby the dial-wheel or disk. l is rotated therewith to one of ,its numerals to the opening 2" in the front of the. case.

When a numeral has been brou ht to the opening 2" the lug "-23- is isengaged from the wheel -6, whereupon the pawl --21 drops by gravity into engagement with the offset of the lever -22- carry .an instrument through the opening 2'.

The described mechanism is operated by 'meansof a crank 24 suitably attached to the projecting front end of the shaft -4=. This crank constitutes a pointer which traverses a dial on the outer face of the front wall of the case, the numbers of which dial correspond with those of the wheel or disk -1 Thesaid pointer is desi ned to be moved primarily to the left by the fperson purchasing milk for the purpose 0 seller the amount desired, audit is adapted to engage a stop 25 on the case to limit its movement and normally lies against the left side of the stop. The said pointer is to be moved back to its normal position by the dealer after he has deliveredto the customer the. amount of milk indicated on the dial by the pointer. l

To operate the machine, the customer first inserts the key..-C into the slot D and turns the key, whereby the engagement of the key with the inclined flange 11 ofthe retaining-pawl -10-throws the latter out of engagement with the ratchet-wheel '9to free the said wheel. The customer then moves the pointer to the left, as illustrated, to indicate the quantity of milk desired as before explained, it being understood that the numerals on the traversed dial may indicate either pints or quarts. After moving the indicator to a numeral of the dial, the operator removes the key -C-'- (which he or she retains), whereby the pawl 10 is caused to automatically move into engagement with the ratchet-wheel'9 to prevent further left-hand rotation thereof, the ratchet -wheel 3 being locked by means of the pawl -15'. The said move ment of "the wheel 9 obviously causes the spring-pressed pawl -12 to drag over the teeth of the ratchet-wheel 3, said teeth being caused to strike the depending lug '19 of the pivoted dog l8 which is caused to move without lifting the arm ate the dog -1S, whereby the lug 20- of said dog engages the offset on the free end of the arm --17- to lift the said arm which throws the retaining pawl 15 out of en-.

gagement with the ratchet -\vheel 3-. When the wheel 3' is thus released it is This locking of the indicating t0 the milk-dealer or- -12 carried on the wheel -9'- as herein:

before stated; This rotation of the ratchet wheel -3 obviously imparts like rotation to the dial-wheel 1-'- whereby the latter is causedin thefirst instance to present to the opening 2-the number corresponding to that which was indicated by the pointer. For example, if the pointer, is set at the numeral one in the first operation of the machine, and then moved back to the stop, the numeral one will be exposed at the opening -2, assuming that, in the next operation, the pointer is set at four, then by moving it back to the stop the dial-wheel -1 will be rotated to such a degree as to present five at the opening.2. It will be understood that by then moving the pointer to one and back to thestop, the dial-wheel -1' will present six at the opening 2, and so on. When the dialwheel -1 has made a complete revolution,

its highest number will have been'brought to the opening 2'-. As the wheel -1 nears the completion of its rotation, the lug +23%- on the ratchet-wheel -3 comes in contact with the curved oifset 22* of 1 the lever 22 depending pivotally from the shaft 16. This engagement of the lug "23- and lever -22- causes the lever to lift the retaining-pawl -21 out of engagement with the ratchet-wheel 6 whereby the latter is freed so as to allow it to be turned to the'left by the'lug 23-. This rotation .of, the ratchet-wheel -6 causes the dialwheel -1f to turn therewith and thus pre- 1 sent in the first instance at the opening -92 40 a numeral corresponding with the highest numeral of the dial-wheel -1--. For ex ample, assuming the wheel 1 to have made a complete revolution-so as to present ten at the opening 2-, then the dialwheel willpresent ten at the opening -2. It is evident that upon the next complete revolution of the dial-wheel -1, the dialwheel -1 will present twenty at the opening 2 and so on. When the dialwheel -l has made a complete revolution, its highest numeral willobviously appear at the opening 2".

It will be observed that, following each movement of the pointer-back to its stop, the

pawl 15 drops into engagement with the ratchet-wheel ,3 and thus locks the dial- Wheel --1-- carried by the latter, whereby the said dial-wheel is prevented from being maliciously tampered with by the insertion of an instrument through the opening -2-,

and at the same time the pawl 10- engages the ratchet-wheel 9 and locks the I, same to prevent movement of the pointer, which latter can only be operated When the pawl -10-1s actuated by the key C- for releasing the wheel -9 Furthermore, the dial-wheel l' 'is normally locked against rotation by the engagement of the pawl -2lwiththe ratchet-wheel, which pawl drops by grzfvity; onto the wheel when its actuating lever -22 is freed from the lug -23 on the ratchet-wheel 3-.

By thedescribed machine, it will be seen that the amount of milk purchased during a week, month or longer period,- can be accurately registered, thus dispensing with tickets which are commonly used by milk-dealers and their customers. What I claim as my invention is z- 1. In a registering-machine for the purpose stated, the combination of an inclosingcase'provided with sight-openings, a pair of ratchet-wheels of different sizes supported in said case and each having secured to it a wheel provided with numerals to be consecutively exposed atone'of the openings, the larger ratchet-wheel provided with means for turning the smaller ratchetwheel for a partial revolution at each complete revolutiqn of said larger ratchet-wheel, retaining-pawls holding said ratchet-wheels against rotation in one direction, amain wheel provided with ratchet-teeth, a pawl carried on said main wheel'and adapted to engage the larger of the pair of ratchetwheels to rotate the same in opposite direction, said main wheel being rotatable in both directions, a key released pawl normally locking the main ratchet-wheel against rotation, means for moving the aforesaid retaining-pawls out of engagement with the pair of ratchet-wheels to permit the latter to rotate with the main ratchet-wheel, and indicating means including a pointer for rotating said main ratchet-wheel as set forth.
