NUMBERING AND MARKING MACHINE..

SPECIFICATION forming part of Letters Patent No. 475,688, dated May 24, 1892.

Application filed April 25, 1891.

To a/ZZ whom it may concern.-

Be it known that I, J AMES D. I-IUMPHREY, a citizen of the United States, residing at Towanda, in the county of Bradford and State of Pennsylvania, have invented certain new and useful Improvements in Numbering and Marking Machines; and I do hereby declare the following to be a full, clear, and Vexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists of a machine designed especially for stamping boots and shoes, dac., with numbers and letters to indicate their size and width and the number of their containing-case. Although particularly adapted to this purpose, the machine can be used whenever it is desired to stamp or print upon any suitable object numbers, letters, or other characters or signs and for which handstamps are now generally employed.

My invention is illustrated in the aecompanying drawings, in Which- Figure l is a side elevation; Fig. 2, an opposite side elevation; Fig. 3, a front elevation Fig. 4t, a plan view; Fig. 5, a cross-section on the line or c of Fig. 4; Fig. G, asimilar section on the line y 'y of Fig. 4; Fig. 7, a longitudinal section on the line .ze of Fig. 4; Fig. 8, enlarged detail views thereof, one view showing more fully the studs or pins of the fractional wheel or disk; and Figs. 9, l0, ll, l2, 13, and la are also detail views of the machine.

In the embodiment of my invention I provide a suitable support composed of a base or plate A and end pieces B B', mounted upon legs a a, all, except one end piece, being preferably a single casting. Upon this base or plate is jonrnaled in suitable boxes b b a shaft C, driven, it may be, by a belt c, encompassing a pulley d thereon, and a pulley CZ on the driving-shaft D, hung or journaled in suitable hangers e c, depending from the under side of said base or plate. 'ihe shaftD is provided with a drive-wheel E. y

The plate or base A has secured or screwed to it at the front end of the machine side pieces A' A', abutting against the end pieces B', thus providing thereat a closure A2. rlhe end ol' the shaft O, projecting within this closure, has connected to it, preferably by a screw, the sleeve or hub f of a wheel or disk EX, hav- Serial No. 390,365. (No model.)

ing in relief upon its periphery a series of numbers E', ranging, say, from l to 13, especially for the purpose of stamping or marking the number or sizes of the boot or shoe in whole numbers. Vithin this closure and in alignment with and arranged so as to form a continuation ot' the series of numbers E are several additional series of numbers F' G' H I', from l to 9, including the 0, also a miscellaneous series of numbers and letters and other characters J', ar-

ranged upon the peripheries of separate marking wheels or disks F, G, H, I, and J, themselves carried by separate concentric tubular shafts F2, G2, H2, I2, and J2. The innermost shaft J2 has a screw-threaded end g, fitted with a nut g', while the several shafts pass through a tubular casting or sleeve 7L integral with the end piece B', one of said disks resting against the inner end of said sleeve.

Upon the outer ends of the several shafts F2, G2, 112,12, and J2 is a series of indicator disks or wheels F3, G3, IIS, I3, and J3, having upon their peripheries numbers corresponding with the numbers on the disks or Wheels F, G, H, I, and J and which are observable through a longitudinal slot h in the plate K, secured over the closure A2. These latter disks or Wheels F3, G3, H3, l2, and J 3 are, as intimated, designed to permit, by being properly turned or adjusted, the bringing of the desired number of the corresponding one of the series of aforesaid marking-Wheels readily into position for use. d

L L L are pawls having teeth beveled upon both their forward and rear edges to permit the rotation of the marking disks or Wheels F, G, H, I, and J in either direction desired and engaging the interspaces in the peripheries of the said disks or wheels between the n umbers thereon, as indicated in Fig. 6. These pawls are hung 0r pivoted upon a screw-rod j, screwed into the end piece B and held so as to readily move thereon by the head of said rod, and a sleeve j', fitted upon said rod bctween said end piece and one of said pawls. They are subjected to the action or pressure of springs k la to hold them forcibly against the peripheries of the disks or Wheels F, G, H, I, and J to prevent the accidental movement or rotation of said disks or wheels, said springs being attached to and reaching upward from said pawls and bearing against a rod l, projecting from the end piece 13'.

The arrangement or series of marking wheels or disks last described provides for stamping or marking the width orother variation in the size of the shoe or boot with numbers or letters, also for numbering or marking accordingly the number of the case or lot to which the goods belong, as well as stamping or marking other articles.

M M are a series of thirteen keys accordingly numbered or marked for actuating the single marking disk or wheel EX, carrying the seriesof numbers E',and M is asingle key having the fraction or other character thereon for actuating a disk or wheel E2, arranged upon the shaft C immediately next and close to the wheel E and having in relief on its periphery the fraction L- or other character, so as to provide for stamping or marking the shoes or boots covering half-sizes or for other use.

The keys M M', preferably straight about one-half their length and curved upward the rest thereof, are sleeved and pivoted at their rear ends upon a rod m, supported upon posts .or standardsm', held in apertured lugs of the base or plate A by nuts screwed upon the lower screw-threaded ends of said posts and by lianges formed on the latter above said lugs.

The keys M M are provided upon the lower edges of their curved portions with shoulders or stops n, the purpose of which will appear farther on, while the straight portions of said keys extend through vertical slots o in a plate N, bolted or secured to the base or plateA in any suitable way, preferably by right-angled brackets p, brazed to the inner side of the plate N and connected to the base or plate A by screws.

Arranged immediately under thekeys M M', inside of the plate N, are as many pistons O O,normallypressingagainst thelower edges of the keys and having their rods or stems O encircled by springs O2, acting upon the pistons and bearing upon the plate or base A. The lower end portions of the piston-rods or -stems O pass through apertures in the plate A, and are partially inclosed and pass through bosses q, cast upon thelowerside of said plate, said piston rods` or stems being keyed in place below said bosses. The keys M M', it will be seen, are thus put under pressure, being pressed upward to effect the automatic return movement thereof after the release of the same by the operator.

P is a bar held upon the outer side of the plate N, directly above and against which the keys M M rest when not in use by means of set or adjusting screws t, working in said plates and engaging keyhole-shaped apertures t' in said bar, whereby it will be seen that with the screws engaging the slot portions of said apertures the bar will be held in position,ac cordingly affecting the keys M M' and the pressure or tension of the springs O2. The

key M' actuates and is connected to the fractional marking wheel or disk E2 by means of a fixed arm J 4, projecting laterally from said key and engaging short parallel studs or pins J5, projecting from the periphery of said disk or wheel. Pivoted upon the outside of the plate N are holding beveled lever pawls or.

latches P,arranged so that their said beveled upper ends partially rest beneath the outer projecting straight portions of the keys M M', whereby as the keys are depressed the latter will engage the beveled portions of said upper ends of the lever pawls or latches and spring or force them to one side, the lever pawls or latches instantly returning under the action of spring-pressure (presently described) and effecting engagement between their hooked portions and the keys, retaining the keys depressed.

The lower ends of theleverpawls or latches P enter notches r in a slide Q, resting upon the plate A outside of the plate N, and guided at one end by a keeper s, secured to said plate, the opposite end of said slide extending into the closure A2 and being formed with an upwardly-projecting portion or arm t2. Rigidly secured to the arm t2 is a rod Q', having a crook or bend q' in it simply to avoid interference with a holding or securing screw of the plate K and projecting through an aperture in the end plate B some distance therefrom, the extreme outer end of said rod having thereon a milled finger-piece or nut Q2.

The rod Q' is encircled or fitted upon its outer projecting portion with a spring R, pressing or bearing against the end plate B and the linger-piece or nut Q2, thus, with the aid of the slide Q, holding thelever pawls or latches P under spring-pressure. The tension of the spring R is regulated by manipulating the linger-piece or nut Q2. By pressing inward upon the finger-piece or nut Q2 of the rod Q' the shaft Q is actuated, and any lever pawl or latch l), holding a key M or M' depressed, is thereby disengaged from the key, allowing the key to automatically return to its original position, the slide and the series of pawls instantly being restored to their former position as the hand orpressure is removed from said nut orfinger-piece under the action of the spring R.

The shaft C is provided with a series of spirally-arran ged studs or pins u, so that each stud or pin will be in alignment with a number of the marking wheel or disk EX, whereby as a key M is depressed and the shaft C is turned a pin or s'tud will be nally engaged by the shoulder or stop n of the key, and thus stop the rot-ation of the shaft and the wheel or disk EX, presenting the required number of said disk upward ready for use, as called by the indicator-number on the depressed key to effect the stamping or marking of the number or size of the shoe or for other purpose.

In order to avoid interference with the motion of the drive-wheel and shaft during the ICO stamping operation, the pulley CZ is held on the shaft C by a frictional bearing formed by a collar V, held on the shaft C by a screw, and in a conical recess of the pulley at one side. Upon the opposite side of the pulley is a beveled or conical hub around its bore, receiving or engaging a correspondingly-bevelended or conical collar V held in engagement with said shoulder of the pulley by the action of a spring YV, interposed between the end of an enlargement of the shaft C and said collar V', and having a spline or feather connection with the shaft C.

T is the inking-roll for applying ink to the several series of marking wheels or disks carried by an L-shaped bracket or carriage T', a detachable bearing-plate 15X thereof directly supporting one end of the shaft t2 of said roll, the opposite end of said shaft bearing in a pendant t3, cast with the horizontal arm of said carriage or bracket. The bearing-plate thas two single screw connections with the bracket T, each screw t passing through oblong apertures or slots 155 in said plate to permit a greater or less vertical adjustment of the inking-roll as may be required to adjust it with nicety to its work. The shaft 252 itself is detachably held in the bearing-plate X by a set or holding screw t, While the inking-roll is removable from said shaft.

The carriage or bracket T has one end of its horizontal arm cushioned upon a spring t7, and through said end of said arm passes a screw ux, whose lower end works in a sleeve or slide u2, traveling on a rod or rail ce, held by screws in eyes of the plate K. The screw ux is provided above the horizontal carriage or bracket-arm with milled jam-nuts um, which, with the spring t7, afford a yielding or elastic connection between the bracket T and the slide or sleeve u2, preventing binding of the latter upon its rail from any irregularity of movement of the bracket or carriage.

The carriage or bracket T is provided at the upper end of its vertical arm with asplit collar V2, clamped by a screw upon a sleeve or slide V3, traveling upon a rod or rail V4, held by screws in eyes at the ends of horizontal arms U U2 of an upright crane-like casting U, integral with one of the side pieces A.

V is a chain or cable connected to a split collar VV, held by a screw upon the sleeve or slide V3, carrying the inking-roll bracket or carriage T', said chain or cable passing around pulleys or wheels, one the large driving-pulley \V and two small ones WX, the latter having their shafts or journals secured upon the arms U U2 of the upright or casting U. The pulley or wheel Wis secured upon the upper end of a vertical shaft NVQ, journaled in a box on a third arm Ugof the casting or upright U and in a box held by screws upon the base or plate A, the extreme lower end of said shaft carrying a toe X for effecting, with the aid of means hereinafter described, the movement of said shaft. The toe X has two sides or faces at right angles to each other, the purpose of which will appear farther on.

Z is the yielding pad for the inking-roll, comprising a plate Z', seated in an opening in the plate K and having depending from its under side a post z, whose lower reduced portion projects through an aperturein the plate or base A and has secured to it a spring e', pressing upon said plate or base, rendering the pad capable of the yielding action. Upon the plate Z is secured the pad proper Z2 at one end thereof, held down in place by a clamp-plate Z3, secured to the plate Z by screws and having an upwardly-curved iiange z2 presented next to the inking-roller.

A3 is the pressure-plate for applying the requisite pressure to the article being marked or operated on, having its suspending or carryin g rod o? passing through a sectional guide a3, one section of which is integral with the casting or upright U, the other section being held by screws to the aforesaid section. The rod a2 is connected by a link o4 to one end of a walking-beam lever A4, pivoted, as at d5, about at its center in an opening a6 in the upper end of a standard A5, held by screws or bolted upon the casting or upright U. The pivot a5 of said lever passes through slots c7 in the side walls of said opening and is secured in the arms of a rectangular yoke AG, fitted upon the correspondingly-shaped upper end of said standard. Fitted upon a screw a8, fixed to the upper end of the standard A5 and passing through an aperture in the upper end or cross piece of the yoke A6, is a milled thumb-nut b', having a recessed flange h2 at its lower end, receiving the upper end of and pressing upon a spring h3, whereby a flexible or yielding connection is provided between the yoke A, carrying the pivot o5 of the lever A4, and the standard A5 to permit a limited play or iiexure thereat, to accommodate the movement of the said lever.

The end of the lever A4, to which is linked the suspending or carrying rod of the pressureplate, is held normally elevated by a spring` encircled or cushioned rod c', piv'oted to said lever and guided in an aperture in the casting or upright U, its spring or cushion pressing upon said casting to accordingly effect the pressure-plate. The opposite end of the lever A'L has connected to it the upper end of a cam-actuated sectional rod B2, the upper section B3 of said rod being diametrically reduced and telescoping the lower section B4 a short distance. The upper section B3 is connected to the lower section B4 by an arm B5, secured at its lower end, preferably by a screw, to said lower section and havingv IOO IIOI

section is a s ring d5, ressin(r u on said nut 'to hold the nut against accidental displace- 'ing the movement of the pressure-plate.

C is a transverse shaft suitably hung or journaled in boxes depending from the under side of the plate A and geared to the drivingshaft D, preferably by means of a cog e thereon meshing with a Worm e2 on the shaft D. The shaft C also has upon one end a cam C2, adapted to engage the toe X on the shaft W2 and actuating the latter shaft. The cam C2, in addition to being formed of a cylindrical portion or collar secured by a screw or otherwise upon the shaft C', has upon its periphery at one end a segmental or semicircular shoulder or projection f3, and at its other end is a stud or pin f 4, so arranged with relation to the latter that a line drawn therefrom to the aforesaid end would pass about midway of the space left in consequence of the projection or shoulder f3 not entirely encircling the cylindric portion'of the cam. Therefore when one side or face 0f the toe X is in engagement with the pin or stud f4, which will turn the shaft W2 so as to move the inking-roll over and cause it to ink the marking wheels or disks, the other face or side of the toe X will be turned toward the segmental projection f3 and the latter be turned to meet it and be brought into engagement therewith a short interval after the stud f4 has become disengaged from the aforesaid face of the toe X.

When the forward edge of the projection or shoulder f3 effects engagement with the toe X at the angle it first presents thereto, during such engagement the shaft W2 will be so turned as to cause the inking-roll to return to its former position at the opposite side of the machine and there remain during the rest of the engagement of the toe X and the projection f3. During the balance of the engagement of .the projection f3 with the toe X, or, in other words, when the opposite face or side of the latter is in contact with the side of the projection f3, the pressureplate will be caused to descend and impart the required pressure to the interposed article to secure the desired impression or print from the marking-wheels. The pressure-plate will also be permitted to ascend or return to its original position before the disengagement of the toe 'X and the projection f2. This movement of the pressure-plate is effected by cam or arm X, carried on the opposite end of the shaft C and engaging a frictional roll or stud e3 on the rod B2, actuating the walking-beam lever A4, carrying the suspending link and rod of the pressure-plate.

To prevent a displacement of the lower end of the rod B2 and yet allow it to have the rel quired movement as it is actuated by cam X', said end of rod is bifurcated or forked, as shown at e4, enabling it to stand astride of the shaft C.

A table C for conveniently placing the work preparatory to be stamped or marked is suitably fastened to the machine at its forward end, and it may be provided with a hinged leaf C3, upheld by a sliding bolt C4 on its under side, engaging keepers upon said table.

It will be seen by the description of the parts and their operation above given that the article can' be marked with a series of numbers or with anyone number without the others or with any set or sets or combination of numbers, as well as with letters without or with numbers. It will be seen, also, that by the separable and independent arrangement of the parts any one part can be easily removed for the purpose of repairing orbeing replaced by another.
