MACHINE-FOR STICKING PINS.

SPECIFICATION forming part of Letters Patent No. 317,173, dated May 5, 1885. Application filed November 3, 1884. (No model.)

To ctZZ whom it may concern:

Beit known that I, JosErH W. NARAMORE, ofAnsonia, in the county of New Haven and State of Connecticut, have invented a new Improvement in Machines for Sticking Pins; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and e'Xact'description of the same, and which said drawings constitute part of this specification, and represent, in,-

Figure l, a side view of so much of a pinsticking machine as necessary to illustrate my invention; Fig. 2, a top view of the same, parts broken away; Figs. 3 and 4, sectional side views enlarged for the better illustration of the invention.

This invention relates to an. improvement in that class of machines for stickingpins into papers in which the machine isadapted to receive single sheets, in contradistinction to sticking in a continuous strip, from which each paper of pins is to be cut. v

The object of sticking pins in single sheets, over the method in which the pins are stuck into a continuous strip, is principally that the papers may be prepared in sheets, printed, gilded, or otherwise treated to give to the paper a finished appearance, which cannot be In machines for sticking in single and separate sheets for each paper of pins, as heretofore constructed, a feeding-roll has been emloyed having crimping devices in connection therewith, the roll being adapted to take one, two, or more sheets, successively gripping the end of the sheet at the proper time, and so that at certain points on the roll the crimping is produced and the pins stuck. The roll, therefore, is adapted only to one particular size of pins, and if other' sizes of pins or yariations of spacing is desired a new roll must be supplied and a readj ustment of the machine necessary, in order to bringl the periphery of the different-sized roll to its proper relation to the other operative parts of the machine, and as such an interchange of rolls is imprac- The apparatus for delivering the pins, the

stickers, and the crimpers are common and AWell-known devices, and need but general description.

A represents the hopper, from which a series of channels, B, corresponding to the number of pins in a row, are inclined downward to the receiver C, arranged to take the pins from the-channel in the relative position to each other in which they will be stuck in the paper. rying punches a, corresponding to the several pins. This slide is arranged in guides E, and

Ato it an up-and-down reciprocating movement is imparted by an eccentric, F, on the driving-shaft G, through a connectingrod, H, and lever I, and so that the column of pinsin the receiver C will, as the slide descends, be forced downward through the crimps of the paper.

Above these pins isa slide, D, car-k L. is the iiXed crimping-bar, and M the movable crimping-bar, to which an intermittent reciprocating movement is imparted by a cam, N, on the driving-shaft (see Fig. 3) in the usual manner, and so as to form the two transverse crinips in the paper, which may be introduced between the xed and movable crimping-bar to receive the pins. This is a common and well-known construction.

Pis the table upon which the sheet of paper to be stuck is placed, its inner end curved downward to guide the paper between the crimping-bars, as seen in Fig. 3.

R is the principal feed-roll,to which rotation is imparted by an endless apron from adrurn," S, on the shaft T. This shaft is parallel with the shaft G, and as here represented stands beneath the hopper. To the shaft T and the drum S,which it carries, an intermittent rotation is imparted from the driving-shaft G, as

seen in Fig. 4t. The said driving-shaft carries a cam, U, which works against a lever, V, the cam operating to throw the lever in one direction, and the spring W to return it, so that 5 by the cam an intermittent vibratory movement is imparted to the said lever V.

On the shaft T is a toothed ratchet, b, the teeth on the ratchet lcorresponding to the number of rows in the paper, the plain or untoothed portion d being left corresponding to the broad space at the center of the paper.

From the lever V a pawl, e, extends to the ratchet b, so that at each rotation of the shaft G the cam U thereon will impart a one-step movement to the ratchet, and corresponding one-step movement to the shaft T, and a corresponding rotative movement to the feed-roll R.

f is the second feed-roll hung in the levers g, one end of each of said levers being hung 2o in theframe above, as ath. Y Only one of these levers is shown in Figs. l and 3. A like lever is arranged at each side, so that a swinging movement imparted to the lever G will move the roll f toward or from the feed-roll R, ac-

2 5 cording to the direction in which the lever is turned, as indicated in Fig. 3.

The two feed-rolls f R are provided with gears, as seen in Fig. l, whereby the rotation imparted to the feed-roll R will be positively 3o imparted to the feed-roll f, and so that their adjacent faces will move downward, the gears permitting the swinging movement of the roll` f, before described. On the shaft T cams t' are arranged, which 3 5 at the proper time, through a connecting-rod, k, will move the roll f from the roll R, and when the cam escapes fromits bearing on the connecting-rod k a spring, Z, will draw the roll f again into bearing against the roll R.

The paper is introduced over the table l?, its end passed down between the crimpingbars L M until its end will enter between the rolls f R, and there will stand until such time as the shaft T is turned, the paper being engaged by the rolls f and R and held stationary; the crimping-bars come together, form thecrimps, and the pins are stuck therein in the usual manner of sticking the pins into the crimps of paper; then the crimping-bars sepa- 5o rate to leave the rows of pins which have been stuck free. At this time the cam U comes into action against the lever V, and through the pawl c on the ratchet b one advance step is imparted to the drum S, and thence to the two rolls R f, to advance the paper the distance for the second row of pins; then the crimping-bars again come together, the second row of pins is stuck as before, the crimpingbars separate, the next step is imparted 6o through the ratchetb to the feed-rolls,and so on. At the center of the paper the long tooth or dead-space d on the ratchet b is reached. When the long space is reached, the pawl e is not able to give the required rotation to the shaft T, and such rotation is imparted by an auxiliary pawl, m, hung to the pawl e, and

which at the proper time engages a stud, n, near the hub of the ratchet-wheel b, and so as to impart to the shaft T the greater extent of rotation required for the broad space. This is accomplished because of the stud n being so much nearer the center of rotation than the periphery of the ratchet-wheel. The pawl m engages with the stud n after the last row of the first series has been stuck, and then imparts to the feed-rolls a movement equal to the space between the said last row of the first series and the rst row of the next series.

The feed is produced irrespective of the diameter of the feeding-rolls R f,- hence by varying the extent of rotation of the drum S-that is, of the shaft T, which carries ita corresponding variation will be made in the extent of feed produced by the rolls R f. If, therefore, a greater number of rows of pins is required, or a less extent of feed for any purpose, it is only necessary to remove the ratchet-wheel b and introduce another having the teeth cut corresponding to the feed to be produced, so that the working parts of the machine'need not be disturbed in making a change in the feed. The ratchet Z1 being upon the outside of the machine of convenient access, itis readily removed and interchangeable with other ratchets.

The cam z' at the proper time-that is, at the end of a sheet-removes the roll f from its working contact with the roll R, and holds it away from the roll R sufficient time for th introduction of a new sheet..

The attendant introduces the sheets successively,in similar manner to the introduction of sheets to a printing-press, the rolls fR closing upon and imparting the advance movement to the sheet at the proper time with relation to the crimping and sticking apparatus.

The variation of the teeth on the ratchet corresponds to the slight variation in the spacing between successive rows of each series, the pawl e engaging the teeth accordingly.

In order that the machine may not continue to run should the operator fail to introduce a sheet at the proper time, I provide a stop-motion, which will stop the machine so soon as one sheet is completely stuck, and such stopping is produced by a cam, o, on the shaft T, which, at the termination of each paper, will strike one arm, r, of a lever hung upon a fulcrum, s, between the shaft T and the shaft' G, the other arm, t, of the lever being in connection with a clutch, u, loose on the driving-shaft G, and so that when the cam turns the lever it will throw the clutch out of engagement with the drivingpulley w, that pulley being loose upon the shaft, and so that when the clutch is so withdrawn the machine will stop. Then when the operator has introduced a sheet of paper he will, through the handle x, throw the clutch into engagement with the pulley and cause the machine to again go through its operation until the sheet last introduced is complete.

Under this arrangement the machine will automatically stop at the completion of each sheet, it being' understood that whatever the length of the paper the shaft T makes one revolution for each sheet, or, what is an equivalent therefor, may make one revolution for two or any number of sheets, it being also understood that the ratchet is made accordingly; if it be, say, two sheets, then two series of teeth and spaces are provided on the ratchet, and so on.

While I prefer to employ the endless apron around the drum S and the feed-roll R, the lconnection between the shaft T and the roll R may be made by simple band and pulleys, or by gears, or by any connection equivalent therefor, too well understood to require further description or illustration.

By this construction no grippers7 are necessary to engage the endy of the paper, and the expensive change of rolls hereinbefore referred to is avoided.

I claiml. The combination, in apin-sticking apparatus, of the pair of feed-rolls Rf, the shaft T, toothed ratchet on said shaft, the teeth of which correspond to the spaces to be made in the paper, a reciprocating pawl adapted to work in said ratchet, and whereby an intermittent rotation is imparted to said ratchet and shaft, an endless band or equivalent connection between said shaftT and the said roll R, whereby the intermittent rotation of said shaft will be imparted to the said roll R, the said roll f hung in movable bearings, and a cam with connection between it and the bearings of the said roll f, whereby the feed-rolls will be separatedat thevtermination of each sheet stuck, substantially as described.
