T 0 all whom it may concern I Be it known that I, EUGENE G. Minimum 'rHALnn, a citizen of U. S. of America, re-

count any number of articles from one to the maximum number which the machine is adapted to hold, and which are of any uniform, unit thickness.

With this object in view the invention contemplates the provision of a mechanism, including an article holder of predetermined length and adapted to hold an exact number of articles of a predetermined, uniform unit thickness, combined with a relatively movable counting mechanism, whereby the latter will express,'in terms of the number of articles of that particular thickness, the amount of relative movement between the holder and counting mechanism. 7

The invention also embraces means whereby relatively movable contacts fix a distance corresponding to the total thickness of the several articles of uniform thickness, together with'means for expressing this distance in terms of thenumber of articles of such uniform thickness included in such total thickness. r V V The invention further embraces means whereby this distance may be expressed in terms of the number of articles included therein, said means being adapted to count articles of any predetermined unit of uniform thickness desired.

Another feature of the invention is means,

whereby when a movable contact is brought up'against the article the contact pressure actuates a further means whereby the movement of the contact is arrested. There is a further provision whereby the contact is arrested always at the same predetermined pressure. V j

In the preferred form of the invention, the device comprises an article holding means adapted to hold a definite numberf of articles of, selective unit but uniform thickness, and movable longitudinally of the articleholding means'is a carriage provided with a counter, and an article contact means which is adapted to yield at'a predetermined pressure and actuate braking means whereby the carriage is stopped in contact position; the article holding means counter, and carriage are provided with interconnected means whereby as the carriage is moved over the article holding means and into articlecontactingposition, the counter registers the number of articles of'that selective unit thickness included inthe dis-' tance traversed.

The invention also comprehends certain further features of construction and combinations of parts which are hereinafter de-' scribed and set forth in the claims.

con

The invention will be readily understood from an inspection of the accompanying drawings and the following detailed descriptionof the construction illustrated therein. I

In the drawings, 7 Figure l is a plan view of the counting device, the table being shown broken-ofi'.

Fig. 2 is. a side elevation thereof. Fig. 3 is a front view lookingdirectly at the article contact plunger, and.

Fig. 4: is a detailed View in section of the contactplunger and carriage locking means.

The machine shown is a portable device adapted to count cards or sheets of paper but it is of course understood that the principle of the invention may be applied to larger stationary machines which might be used a paper plant where at the present time sheets are counted individually, en

tailing a' largeamount of labor.

the base 1- of the machine is providedat its upper portion with a=carriage slide 2: and a rack 3, the latter being preferably on the under side andarranged centrallywof'the base thereof, one end of which terminates in an upstanding arm or abutment 4 against which the sheets of paper to be counted are In the illustrated form of the invention--- placed, the-thicknesses of the paper extending lengthwise and resting on the top of the base which is formed into a sheet hold vided at the sides, preferably, with the projecting arms 7 to engage the base sides. on each side of the central rack and also extending lengthwise of the table are the slots 8, 8, through which the arms 9, 9, project downwardly from the carriage and. these arms are provided at their lower ends with the bearings 10, 10, for the shaft 11, which has fixedly mounted thereon a pinion 12 7 adapted to mesh with the rack 3, whereby when the shaft is turned the carriage will be translated over the length of the table.

At the front, the carriage is provided with housings for the article contact plun ger 13, and the carriage locking rod 18, respectively the former being providedwith contact head 1 adapted to be brought into contact with the articles on. the table and normally projected in advance of the carriage by means of the spring 15.- A. nut 16, limits its extreme movement in this direction. Preferably arranged beneath the contact plunger and adapted to be actuated by the contact head 14: is the carriage locking rod 18 provided with cam faces 19, 19, adapted to press the friction braking studs 20, 20, into contact with the stationary frame of the base 6, whereby the carriage is held in fixed position. This rod 18 is likewise projected into forward position by the spring 21. On the carriage and to the rear of the plunger bracket is mounted the shaft22, on which is fixedly mounted the gear 23, adapted to mesh with gear 24, fixed on the lower carriage or co'untingshaft 11. On the extreme outer end, the shaft 22 is provided with a crank arm 40 for rotating said shaft, but it is obvious that any means may be used to rotate the aforesaid shaft. On the inner end the shaft 22 is fixed the gear 25 and this gear, through an intermedn ate train of gearing mounted on the carriage,

drives a shaft 26, which in turn is adapted to drive a shaft 30 by means of any desired,

type of variable speed drive, in the present instance shown as the ordinary conical surface drive including the adjustable friction V cones 28 and 29. The cone 28 is fixed on the shaft 26 while the cone 29 is fixed on 7 the'sha'ft 30. Any suitable means may be used for rovidin an ad'ustable mountin D for the shaft. 30. In this illustration a guide 31 is made integral with the carriage 6 and runs parallel with theface of the cone 28.

Mounted for movement in this uide is the block 32 provided with the universal mounting 32 for the shaft 30. The block 32 is adjusted-by means of the usual'micromcter screw 33 and the bracket thereof is provided at a convenient point with'scale divisions corresponding to various thicknesses of articles to be counted.

As shown in the drawing the graduations are arranged for paper sheets having thicknesses from .003 to .006 inches,.but it is to Operation.

The carriage is brought back to its extreme rear position or initial counting position at which place the recorder reads its maximum. The bundle of sheets is now placed against the abutment 4 with the thickness of the bundle extending lengthwise of the table. The crank 40 is now turned,

rotating the shaft 22 and advancing the carriage 6 along the rack 3 and over the table, until the contact plunger 13 hits the foremost sheet, pushing back the plunger 13 until it contacts with the locking rod 18, whereupon it is caused to rccede into the housing and the cam faces thereon depress the braking studs against the stationary frame, holding the carriage locked in contact position. The carriage is released by rearward movement. It will be noted that because of the small pressure surface of the head 14 of the contact plunger 13, the contacting pressure is transmitted over only a small section of the articles to be countedthus requirlng the minimum force to beenerted on the carriage actuating lever 40. The uniform pressure of the spring 15 provides a means whereby the same pressure is brought to bear on the package of sheets irrespective of whether these are one or any number of sheets theiein. Hence the car riage is always stopped at a predetermined pressure of the carriageoperating means, and the carriage islocked as soon as the predetermined pressure has been reached.

By fixing the length of the rack on the sheet supporting table 1 to correspond tothe total thickness of a predetermined numberofsheets of a predetermined uniform thickness, and by fixing the length of the cir'cuInalong the rack the translation and rotation of thepinion canbe availed of for register ing the number of sheets included in-. the distance along the rack the shaft is trans-- .lated. For instance, the movement of one tooth distance of a rack and opinion having a circular 'pitch of 0.1571 inches corresponds to a carriage movement over a dis-V tance equal to 52.3666 sheets of .003 inches thickness per sheet. So that when the carriage travels from initial counting position When it is desired to count sheets of different thickness the gear ratio between the pinion 12 and the shaft is correspondingly changed bymeans of the micrometer 33.

A machine such as described is adapted to handle any shape or length of sheet without making any changes and is adapted to count a large number thereof rapidly with only a very small percentage of error, due to the ordinary variation in thickness of each sheet.

While I prefer to employ the construction and arrangement of the various mechanisms embodying the features of my invention in the form in which I have shown them in the accompanying drawings, it will be understood that various changes and modifications in the specific construction of the parts and in the specific construction and arrangement of the various mechanisms may be made without departing from my invention.
