Specification of Letters Patent. Pgmtqgntgdl lwmr, 15,1916).

' Application filed July 19, 1909. Serial No. 508,257.

To all whom it may concern:

Be it known that l, EARL M. PLUMMER, a

citizen of the United States, residing at Man shalltown, in the countyof Marshall and State of Iowa, have invented certain new and useful Improvements in Adding-Machines, of which the following is a specification. v

This invention relates to certain new and useful: improvements in adding machines.

The object of this invention is to provide a game counter especially adapted to be used in keeping a correct score of all points madebe made within the scope of the claims with-.

out departing from the spirit of the inven tion. I

In the drawings forming a part of this specification, and in which like characters of reference indicate similar parts in the several views, Figure 1 shows a front view of a game counter embodying my invention, Fig. 2 is a side view thereof, Fig,3 is an enlarged I detached front view of the checkrack, Fig. L is an enlarged side elevational view with parts removed, Fig. 5 is a side view of a first tier operating lever, Fig.6 is a side View of one of the second tier operating levers, Fig. 7 a side view of one of the third tier operating levers, Fig. 8 is an .enlarged front view with parts removed,

Fig. 9 is an enlarged detached detail of the detent, Fig 10 is an enlarged detached detail of the main bearing plate, Fig. 11 is. a side view of one of the bearing posts, Fig. 12 shows an enlarged detached side elevational view of the setback leverused in my invention, Fig. 13 shows a detached enlarged side elevational View of the reset lever used in my invention, Fig. 14: is a detail of the shaft sleeve, Fig. 15 is a detail of the drive Q'ear, Fig. 16 shows an. enlarged detached de-v tail of the stop pinion.

The aim of my invention, is to provide a recording mechanism adapted to be used by one or more players, in recording and scoring the points made in the games played upon a pool or billiard table.

My game counter is intended to be hung upon the wall, or the same may be used upon a horizontal support.

In the accompanying drawings, 15 represents a base preferably of wood, provided with the top 16, the two similar sides 17, the face plate 18, ending in the beveled edged bottom section 19, below which is held the panel 20, as shown. The sides 17 are reduced at the forward end and terminate in the reduced portions 21 as disclosed more clearly in Fig. 2. Held to the bottom member 20,- which-isthe form of a batten preferably made of wood, is the shaft secured by means of the end bearings ll fixed to the batten 20 shown.

Held between the reduced forward ends 21 of the sides 17, and secured y means of the screw? 24 is the check rack 25 a detail of which is shown in Fig. 3. This check rack is provided with five lever slots marked A, B, C, D, and E as shown. These lever slots are all of an equal width, but each has a step formed bottom. The three steps forming the bottom within the first lever slot are marked 30, 31 and .The bottoms within the second slot B are mark- ed 31, 32 and 33; the bottoms within the lever slot C being marked 32", 33 and 34. Thestop bottoms within the lever slot D are marked 33', 34 and 35, while the stop bottoms within the terminal slot E are marked 34, 35 and 36. In' order to more clearly bring out the operation of the levers in connection with this check rack, I have divided this rack into a plurality of lengthwise dislevers M a detail of one of which is shown with a finger plate 47 in the form of a disk,

each disk having a suitable number as is shown in the front View. In this view the uppermost tier of the finger plate is marked X, the intermediate tierY, while the lower tier is marked Z. As shown in the side view,

each like set of levers is slightly longer than the preceding set while the outer ends of the different sets of levers vary in length,"the inner ends of all of the levers terminate in alinement, each lever being provided with an upwardly directed nosing 39.

Held to the base at a suitable point is the bearing post a detail of which is shown in Fig. 11, and this post 40 is provided near its upper end with the bearing 40.. Held adjacent to this bearing'post 40 is the main bearing plate 42, provided with the bearing 43 held inalinement with the bearing 40, this main bearing plate being provided with the additional bearing 44 as disclosed in Fig. 10 where a detail of this bearing plate is shown.

Held within the bearing 40 and the bearing 43, is the driveshaft 45. Secured to this drive shaft 45, is a ratchet wheel 46, provided in this instance with two hundred notches. Held upon this drive shaft 45 adjacent to the ratchet wheel 46, is theshaft sleeve 47 having the collar 48, which collar is secured to the ratchet wheel 46, while-pass ing through an opening in the shaft sleeve 47 is the-pin 49 which also passes through a suitable opening within the drive shaft, sov

that this shaft sleeve is securely fixed to this drive shaft in the manner shown.

Held upon the shaft sleeve 47 isthe hub 52 of the drive gear 51, which hub is provided wit-h the opening 53 through which the pin 49 passes, so that this pin secures the hub 52 as well as the collar 47 to the drive shaft 45.

Held within the bearing 44 of the main bearing plate 42, and a bearing within the upper end of the post 54, is the driven shaft which at its outer end carries the driven pinion 57 having the hub 56 through which a pin passes securing the hub to the shaft 50. This shaft 50 passes through the wind ing wheel 59 this wheel being secured to the shaft by means of the disk 60 provided with the hub 61 through which the pin 62 passes through an opening within the driven shaft 50, so that this winding wheel is securely fixed to this shaft 50'. The driving gear 51 meshes with the driven pinion 57. The winding wheel 59 is preferably'made of wood and is provided at a suitable point withthe pin 63' which projects outwardly therefrom as disclosed in the frontyiew.

Held upon the pin 64 carried within the bearing plate 65 is the stop pinion 66, this stop pinion being positioned within the path of the pin 63. As shown in Fig. 16,this stop pinion is provided with four teeth and a cam formlng portion 1/, the instrumentalltles being so arranged that as the winding wheel rotates, it will rotate the stop pinion 66 until the stop shoulder 3 is encountered when the movement of the winding wheel is stopped and checked. The wheel must then be reversed so that the stop teeth are carried in an opposite direction until the pin again encounters the stop forming portion 3/. From these it will be seen that this pinion 66' acts as astop to limit the movement of the wind- -shaft arranged to receive the securing pin 72.

Secured to this drum 69 by means of the pin 73, is the strand 74 carrying at'its free end the counterpoise 75 as clearly disclosed in Fig. 8. The spool 70 is seeured to this drum shaft by means of the collar 76 which also has apin opening as has the drum shaft arranged to receive the pin 77 by means of which this collar and spool are connected to the drum shaft. Secured at one end to the spool 70 and atthe other to the winding wheel 59, is the tape 78 of suitable nonstretchable material which is provided witlr numbers running from 0 to 200 consecutively. The panel 18 at a suitable point is slotted to permit the protrusion of a portion of the winding wheel 59, the panel at this slotted point being provided with the hood 79, having the glass covered opening 80 through which the tape numbers may be seen. Secured to the base 15 at a suitable point adjacent to the ratchet wheel 46, is the bearing plate 81 carrying the pin 82 to which is secured the spring 83, as shown in Fig. 9. Held above the pin 82 is the pin 84 which pivotally carries thepawl 85 having the downwardly extending end 86 engaged by the spring 3 so that this pawl 85 is in normal engagement with theratchet wheel 46 as clearly indicated in the side view.

Extending from one ofthe sides 17 to the other is the bar 87, which carries a plurality of springs 88, there being one spring for each lever as shown. Pivotally held upon the drive shaft 45 are the two rock arms 90. These rock arms at their ends are'seoure o 'the pawl plate 91 which is of a'length so i said plate extends above all of the upwardly directed lugs or nosings 39 carried at the inner ends of the operating levers. Secured to this pawl plate 91. is the ear 92 carrying the pin 93 which in turn pivotally supports the pawl 95 engaging the ratchet wheel 40, a spring 94 being secured to. this pawl plate and operating against the outer end of this pawl 95 to insure normal contact between the pawl 95 and the ratchet wheel 46. Posi tioned behind the pawl plate 91 near each end, is a stop plate 97 having the outer upwardly directed stop ear 100, these plates being secured to the base 15 by means of the flanges 9S, and extending from each of these stop plates 97 is a spring 99 secured at its upper end to the pawl plate 91, insuring this pawl plate at all times being in spring pressed engagement with the stop ears 100.

Slidably held to the base 15, by means of the guide yokes 101, are the members 102 and 108, the first forming what I call a re-;

set rod and the second beingv the setback rod. The reset rod is disclosed in detached detail in Fig. 12 and is provided in front with the push plates 104 disclosing the legend Setback. At its inner end this lever 102 carries the cam plate 105 having an obliquely held upper contact edge 105 arrangedto' contact with the projecting end 86 of the pawl 85. Intermediate of its ends this reset rod is provided with the trip arm 106 having the nosing 107 arranged to contact with the pawl 95 to release the same from engagement with the ratchet wheel 46. The setback rod 103 is provided at its forward end with the push plate 108 disclosing the legend Setback and intermediate of its ends is provided with the stop collar 109 while projecting upwardly from this lever is the stop pawl 110 the upper end 111 being arranged to come into engagement with the teeth of the ratchet wheel 40 in one position of this lever. Extending fromthis stop collar 109 is the spring 109 secured to the forward batten 20, so that this setback rod is normally drawn outward, in which position the stop pawl 110 will be held immediately in front of the ratchet wheel 46. The out ward movement of this lever 103 is checked in that the stop pawl 1110 comes in contact with the rear yoke 101. Extending from the trip arm 100 to the batten 20 is the coil spring 100' insuring this lever 102 normally being .held in an outward position. As shown in Fig. 4. the stop collar 109 is held adjacent to the trip arm 106, so that when the. set back rod 103 is actuated, this collar 109 will contactwith the trip arm 106. Thus the reset lever is freely movable independently, but upon operation of the setback lever the reset member is also moved.

\Vhen the instrmnentalities have been properlv arranged the operation of my device is as follows: To record one point, the operator would depress the first lever provided w1th the finger plate having the numeral 1, this lever would then be depressed one division of space upon the check rack to engage the bottom 30 which would ad, vance the ratchet wheel one tooth and the winding wheel 59 a suitable distance so as to bring the numeral 1 upon the tape below the glass 80. Should the next point scored be 4, the lever having that number would be depressed so that the lower edge thereof would engage the stop bottom 33". 'The first tier of levers registering the numerals from. 1 to 5, are stopped by the first bottom within each lever slot. The outwardly projecting end of the lever series M, however,

is so arranged, that the ratchet wheel 46 will be advanced four teeth before the upper edge of the check rack is encountered. If

the number to be recorded amounted to 8, the connected lever would advance the ratchet wheel 46 four teeth before the upper edge of the check rack were encountered, and advance'the ratchet wheel four teeth in entering the slot. The upper tier of levers have their ends so bent that the ratchet wheel is advanced eight teeth before the bottom of the lever enters the lever slot after which the lever is permitted to pass downward engaging the stop bottom within the check rack. If'the score made amounted to thirteen, for instance, the lever 13 would travel the distance of eight teeth above the check rack and then the five divisions within the lever slot below and be stopped by the bottom 34.

In certain pool games, when what is called a scratch is made the player loses one point. In order to set back the score one point the operator would actuate the setback lever which would result in .the upper end or nosing 107 of the trip arm 100 engaging the projecting end of the pawl 95 and the cam plate 105 engaging the pawl 85 to disengage these pawls from the ratchet wheel. At the instant that these pawls became disengaged from the ratchet wheel 46 the stop pawl would be carried below the teeth of the ratchet wheel 46 to check the movement of the ratchet wheel after the space of one ratchet tooth has been passed resulting in the counterpoise 75 rewinding the tape one number. At'the conclusion of the game, it is necessary to reset the machine, which is accomplished in pushing back the reset lever 103'which results in the nosing 107 engaging the pawl 95 while the cam plate 105 engages the detent 85 to carry the same out of engagement with the ratchet wheel 46. As soon as this ratchet wheel is released, the

eounterpoise 7 5 operates the drum shaft 68 said shaft, a pawl pivotally carried by said said operating levers into contact with said to rewind the tape 78 upon the spool 70. The machine is then ready to be used in scoring a newga ne.

The machine is simple in construction, there are noparts likely to become inoperative, and the device is positive in its action, both in recording the scores as well as in the resetting of the instrumentalities.
