WILLIAM E. CHOATE, OF MELROSE, MASSACHUSETTS.

Specification of ietters Patent.

Application filed September 10, 1906. Serial No. 333,892.

To all whom it may concern."

Be it known that I, lVILLIAM E. CHOATE, a citizen of the United States, residing at "Melrose, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Stencil-Cutting. Machines, of which the following description, in-connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

-My invention relates to machines for forum 'ing letters or other characters upon blanks of suitable material, more particularly to sten- .cil cutting machines, wherein a series of tools each adapted to punch or cut out a separate letter or character are mounted in a head or carrier moved to bring the tools into opera tive position as desired.

My invention aims to provide a compact machine or apparatus ofnovel and simple construction and operation, and which may be easily, rapidly and accurately operated by hand.- The invention, however, will be best funderstood and appreciated by reference to the following description when taken in connectiouwi-th the accompanying drawings of a machine illustrating one embodiment of any invention and selected for purpose of "illustration, its scope being more particularly pointed out in the appended claims.

Referring to the drawings :Figure 1 is a front elevation with parts broken out of a stencil cutting machine embodying one form 30f my inventionand selected for illustration herein; Fig; 2, a plea thereof with parts broken away; Fig. 3,'a vertical section taken on the line 3-3, Fig. 1; Fig. 4, an enlarged vertical sectional detail of the peripheral portion of the carrier to Show the arrange- 410 ment oft-he die punches thereinpFig. 5, a detail to show the ball bearings'for the punch carrier and the norel'ball retaining plate therefor;- Figs. 6 and 7 are enlarged vertical sectional details taken on the line 6-6 and 77, Fig. 2, respectively; Fig. 8,

an enlarged detail of the carriage rack and its actuatingpaw'l to be referred to; and Fig. 9, a modified construction of the means for mounting the line spacing pin; a

In the present embodiment of my invention, referring first to Fig. 1, the machine is provided with a suitable hollow stand A,

upon which the operating parts are suitably supported, and comprising in the present insaidcolumn, 2, so that each tool or stencil o, may be brought into a desired opcrative position. As here shown Patented Feb. "1,1911.

said carrier, 4, is formed as a. rotary d1sk or wheel, .thehub, 6, of which surrounds and is suitably journaled on said column 2, thelatter. in the present instance, beingpro:

' vided with' a shoulder, 7, on which the lower end of said hub rests'and is \'ertica]lyj up-- ported, suitable ball bearings beinginterposed to facilitate rotating said (34113316134, thereon. In the present instance, (seeFigs.

3 and 5) the balls of said bearings are;-re-

tained in place by a novel retainingtdevice comprising a frusto conical ring, 9, ogee in section (Fig. provided with a series of circular openings or'apertures, 10, for said balls, and by which they are suitably-spaced apart and retained in place while permitting them to roll freely between said hub and its supporting shoulder, 7.

Any suitable means may be provided for holding the, punches, 5, 1n posltion, but-1n the present embodiment of my invention (see Figs. 3 and 4) the rim of said wheel or disk preferably has a series of vertical recesses, 11. constituting guidesfor said stencil punches, 5, and permitting them to be reciprocated vertically therein. This punch wheel carrier is substantially similar in construction to what is known to the trade as a hunting-tooth wheel, the punch recesses being formedat the periphery of said wheel bet-ween the upwardly projecting tapered hunting teeth thereof, said punches, 5, -be-- ing retained therein by an exterior circumferent'ial flat. ring or bandr12, 'suitablyseu cured to the rim of said wheel Flyby-any suitable means, as, in vthe present instance,v

by shrinking. In order to indicate the operative the particular punch'monnted in the space between two adjacent teeth of s aidf wheel, said band, 12,is provided atits outer face. with the usual characters employed in -60 the head of the column, 2.

printing or cturespondencc, each of said character being placed or centercd opposite the correspmitliug punch, or. to express it difierently, the punches being removably I 5 carried in their carrier are placed opposite to the corresponding characters on said band. Preferably, however, said band is provided with a peripheral recess removably to receive a ribbon, of'any suitable maiu terial as metal, celluloid or the like, on whichsaid characters are formed or secured. This arrangement permits the employment; of ribbons having a difl'erent arrangement of characters or difi'erent characters avoiding the expense of stamping or otherwise marking the band, 12, when changing the l characters or providing a plurality of-bands or carriers.- That the punches may be normally maintained in elevated position, said wheel is provided beneath its teeth -with an inner peripheral groove, ll (Fig. 4), com mimicating with the recesses in which the punches are mounted and receiving a series of torsionally acting lifting springs, 15. Each of these springs has its inner end,'l6,

seated at adesired angle in said'wheel, and I its outer end, 17, apertured into one of they punches,.5. These springs normally act to elevate their punches until -said ends, 1'7, engage the upper face of said groove when further-vertical movement is prevented. To j depres each tool or die, 5, when the carrier, 4:, is rotated to bring said punch singly into its' forward or operativeposition (see Figs.

3-5 1 and 3.)..a suitable actuator or presser. 1S-is' preferably provided, the lower end of whichis adapted to enter the space-between ad a- 1 cent hunting teeth of said carrier and bear uponfand depress the punch mounted be- 4o tween them to causeit to operate upon a blank or sheet of stencil material positioned beneath it by suitable blank holding and feeding mechanism. presently to be described. This presser, 15, in thepresent instance, is j clamped between the forked ends of an actuator lever, -19, (Fig, 3), pivoted .in

' teriorly atits inner end upon a pivot pin; 20. extending between and secured to the sides. of said column. 2. said column being provided at its front with a suitable-vertical slot, 21, to permit the oscillations of said actuator lever, 19. This lever is normally held elevated by a coil spring. 22. connecting itwith a pin, 23, on the head of said column. which is provided with a slot,

' 24, for the upper end of said spring and to.

facilitate its removal 'when desired. produce suitable depression of the punch by means of the actuator. 18. and said lever. 19.

extends forwardly and is provided with overhanging vertical cars, 25, between which is pivoted upon a xhoriiontal pit-iot-p'imQG, a cam lever, 27, the

lower end of which, beneath said pivot pin, 26,-

6 is provided with a cam,28, which rests upon a i sion of said cam roller, 29,

operating .the cam lever,

Tof roller or other stud, 29, suitably journaled between upwardly projecting ears formed upon the front forked end. of saidlever,.19. In the elevated position of said cam ever,

227 (see Fig. 3), the lowpartof the cam, 28,

engages said roller, 29, maintaining the ac-' tuator'lever and. said roller in elevated position by theraction of said springs, 22, with the actuator, l8,'above the upwardly probring any desiredlet-ter of the ribbon and I the corresponding punch into position beneath said actuator. In depressing said lever, 27, however, thecam causes a depresand the actuator l lever 19, whichcarries it, depressing said actuator, 15, between the upwardly projecting and ad acenttapering hunting teeth of the carrier and by itsfurther movement depress ing and operating the punch to-cut'the character corresponding to the letter in front of it; In case the-carrier has not been turned sufficiently to-place the desired punch 11lrectly beneath 'theactuator, the latter upon being depressed will engage o h other ot the: tapered hunting teeth between which the punch 15 mounted and by its action on the inclined face of said tooth rotate the carrier toenactly center the punch beltv the actuat'or, 'which also brings said punch into properposi-tion relative to the ml; and the letters previously cut therein. To cooperate with the punches in cutting the stencils, I have, in the present instance. provided 'a yielding bed, l3. preferably composed of a plurality of strips of thick pa r superposed one on the other and more in y described later; a

Any suitable means may be employed for but as here shown (Fig. 3;] its outer'entl preferably provided with a suitable handle. 27- to facilitate.operating it. limnediately in the rear of the inner end of said lever and ire-- mediately above its cam,- the forked head of theeoluinn has an upwardly extending lug" in which i 4 ably mounted a stop screw. to limit the upward movementlof'said lever.- In normal adj'usnnent, the tension of the lifting or elevating spring,"22, i's-such as to ca-use'the roller. 2-9. to bear upon the cam. 28.,withsufiicient. force to swing the ever. 2T,."into the normalslevated position shown in' Figs. 1 and I A: the sheets or blanks: 'of material-employed and from which stencils are formed.-

are of different thicknesses and as they also vary somewhat inumformity. and as the, cutting bed presently described occupies a fixed vertical position beneath the punches.

means are advantageously provided to ad just the presser, 1S, vertically. so that when" operated it may cause the desired depre slol'i of the. punches to cause them to cut through the stencil plate into and against saidriutting bed and also to limit the motion of the prcsser to prevent a greater movement than sutlicient for cutting or punching the characters. To this'end (see Fig. 3) said presser, 18, is removably and adjustably secured to said actuator lever, 19, the latter having a forked headlbetwecn the arms of which the upper end of said presser is received and clamped in position, and. is-

provided with a cutaway circular portion, 30. A horizontal clamping bolt, 31 (see Figs. 1 and 3) extending between and clamping the forked ends of said lever, 19, together has an intermediateeccentric portion, 32, against which said cut-away portion is placed. To adjust said presser, 18, vertically, the clamping bolt, 31, is turned so as to cause the eccentric portion, 32, to rise or fall somewhat and the portion, 30, being held against it permits such vertical adjustment of said presser as may be desired, when the bolt, 31, may be again clamped in adjusted position.

To prpvent the face of the punch being depressed into contact with the metal of the central bed strip guide or anvil, 33 (Fig. 3),

to be described, the vertical depression of the presser, 18, is limited by the throw of the cam, 28, thereby also preventing itfrom striking the inwardlv extending flange or rim, 34, of said wheel or carrier, 4:. This arrangement permits any desired adjust mom of the punch within fixed upper and lower limits, and prevents any injury to the .cutting face of the punch itself. The depression of each punch brings its cutting face into contact. with the sheet of stencil material placed beneath it through which it cuts the particular character represented by the corresponding character on the rim of said carrier, 4. a

In order to ho]d the blank of stencil matrial in suitable position and to feed or since it accurately in cutting out the characters suitable holding and feeding means are provided. To this end, the front of said column. '2. is provided, in the present instance. with a forwardly extending lug, (Fig. 3), upon which formed a horizontal support, 36 (Figs. 1 and 2),extending across the front of the machine and forming a yoke, its forwardly extending arms, 3'7. supporting a guide rod, 38 (Fig. 2). for a stencil plate holding and feedii'ag carriage,

39 (Figs. 2 and (3), which is slidable there on from left to right and vice versa. The upper face ofthis support, 36. isprovided with right and left guides. 40, 41, respectivel v, and with an intermediate upwardly projecting lug. 42,1'ecessed-at its upper face to constitute the guide and anvil, 33, referred to. for the movable bed. strips, 43, and against which said punches out. The

of said rack.

bot-1y of the carriage, 39, referred to, is tubu lar in form constituting a sleeve slidably mounted on said guide rod, 38, and that said carriage may be prevented from turning on said guide rod, it is provided at its under side with a longitudinal vertical recess, lag

To oscillate this rock shaft .arm, 50, anysuitable'means mayybe em ployed, but in the present embodiment of my invention, its inner end is preferably provided interiorly of the column, 2, with ahorizontal arm, 51 (Figs. 1 and 3), connected at its outer end by a link, 52, to said actuator lever,-19, so that upon depression of the latter, through the operation of said cam lever,,27, said link, 52, isalso depressed. This movement of the link depresses said horizontal arm, 51 (Fig. 1) rocking said shaft, 50, and swinging its exterior vertical arm to the right, carrying the pawl with it and causing it to slide freely over a tooth The reverse movement of said link and shaft, 50, caused by the contraction of said spring, 22, when the handle is ele vated or released, swings said arm, a l), and its pawl in the opposite direction, causing the latter to engage the rack tooth, referred to, and slide the latter to the left, so that the carriage will be moved one step also to the left, thereby to space the blank or sheet of stencil material to aposition to be operated upon by the nextpunch'. In the present in-v stance, the spring, 53 (Figs. 7 and 8), which normally retains the said pawl. 48.,in engagement with. said rack, is inserted in a circular groove, 5-1, formed in the front face of said pawl and concentric with the, pivot pin on which the latter is mounted, itsends being turned in opposite directions,I one -of which is seated in an aperture formedin" the pawhand the other in an apertu i'e in the rear face of the arm, 49, said spring nornially actin'g toelevate the outer or-right end of said pawl into engagement with the teeth of said rack. As here shown, said pawl slides upon the front face-of said rack and that-it may positively actuatethe same, it is provlded with-a rcarwardly-extendinglor oil s aftgf T (Fig.

' I i i 3 and 6, thecarriage, a9, is provided with suitable means tor holding the stencil plate in position to be operated upon and while the carriage is ted or reciprocated on said I vided guide rodtBS. In the presentinstance. said means comprise a normally horizontal plate holder T-.l, pivotally comiected at its front end with a normally vertical swinging frame, 7-5, in turn pivotally connected at its lower end between forwardly and downwardly curved arms. 76. of said carriage,

39, and provided with laterally extending stop arms, 77 .(Fig. 6). Said arms. 76. are adapted to engage the rear and lower edges of said arnis. 7?. and limit the outward movement thereof. thus preventing said frame, 75, and theholdelgfTet, from swinging outward or forward more than sufficient to facilitate inserting the stencil plate in position. For nori'nallydepressing the .rear or blank receiving portion 'of said holder. 74, a coil spring, TS. is connected with sald plate inthe rear of its pivotal,

To prevent holder below a horizontal or operating position', the carriage, 39, is provided with a vertical supporting bar or plate, 79 (Fig. 6), removably and adjustably secured ther on, so that it may be moved in or out and the bottom of said holder. ends,. has a horizontal here shown in depel ldingearsor lugs on said holder, 74. In the present instance, this-pinis pro titled with a plurality of flat faces, having tches, 81;. formed therein and adapted to )e singly engaged by the upperedge of said erticalbar, 79, for positioning the holder lVhile any suitable number of notched faces may be provided, in the present instance but four,

notched line spacer vided with two, three, four andfive notches. each of said brought intothe-lowe r position by turning said pin, so that its notches maybe engaged by said supportingplate', 79( 1T0 prevent this pin from sliding in its l-i'carings. the outer pin bearing, in the present instance, is provided with; a vertical stop. here shown as a screw. 91'. the in-nerend of which is received'i-nja circiun'feren't'ial' groove, 92; of said-pin. This; construction permits the pin to be turned on rotated freely in its bearings for adjusting it but prevents any longitudinal movement, so that as the holder and the blank held thereby are moved to bring the next notch of the pin upon the supporting bar; 79, there will be no variation in the interval orspace between the lines and corresponding to the space betw' -n the notches o the pin.

Its open end has a spring pressed ball. 95. of the same diameter as the socket and which prevents lateral movement thereof, the lower portion of said ball entering said groove. 92, and maintained in frictional contact therewith by a coil spring. 96. seated in said socket, 94-. and acting to depress the ball. In turning the pin to bring a desired notched face to line spacing position, the ball rotates freelyin its socket but prevents the pin from moving either inwardly or outwardly, thereby maintaining the holder in the proper line position, as describe-c. The holder is moved to cause each of said notches in succession to rest upon sa id support, by tilting the carriage bymeans of the rearwardly extending finger piece, 82, and sliding' the pin over said plate support until the next notch is brought into engagementwith its edge. By this arrangement, any desired number of be cut upon the stencil sheet or blank, preserving" the required or desired space between the characters cut in said lines and arranging the lines symmetrically upon the blank.

That a stencil Eblank may be suitably clamped upon the holder, the latter, in the present instance, is provided with a spring pressed lever, 83, best shown in Figs. 3 and 6. the rear end of which has a horizontal clamping plate or jaw, 84, to engage the upper rear face of said holder or to clamp the rear edge of the stencil blank between them. The opposite end of this lever has a torwardly-projecting thumb piece to facilitate elevating the said clamping jaw, 84. to permit insertingor removing-the stencil blank. That the stencil blank may be suitably positioned in said holder between said jaw and the face of the plate beneath it, the latter is provided at its right and left ends with suitable horizontal slits or recesses to receive the front edge of said plate and which are of uniform depth. so that the edges of the stencil plate may be maintained parallel with the line of travel of said carriage or with the line of'clniracters cut therein by the punches.

To prevent loosemotion of the carriage, 39 on its guide r0d,38, the left end of said carriage sleeve (see Figs. 1 and 7) 15 provided with -a horizontal screw; 85, tapped into a horizontal recess in the sleeve portion of said carriage. The bottom of this recess receives a friction disk, 86*, bearing upon said guide rod, 38, and n'efera'bly of brass, between which and said ilClJllSlllllg screw a coil spring, 86, is interposed, the tension of which may be adjusted by turn- LOO is next again tilted bed strips. *3. and to riage conveniently in o said screw. thereby to vary the pres sure of the disk against the guide rod and obviously preventing loose motion. By providing a friction bearing of this type the necessity and use of oil is avoided.
