  • Said guide-surface is so formed as to hold the bar and connected lever in their outermost positions during the greater part of the rotation of said shaft; but at a given time in the rotation thereof it permits said bar to move endwise toward the guidesurface, and thereby allows the lever Q under the action of the spring Q to be oscillated to move the clutch M out of engagement with the pulley M

  • Said bell-crank lever R is so arranged that when the actuating-bar connected therewith is in its innermost position or engaged with the recess S of the pulley S the rear end of the treadle-arm K will be depressed and the outer end thereof elevated, at which time, as before stated, the clutch will be disengaged from the pulley M When, therefore, the forward end of the treadle-arm K is depressed, it, will act through the connecting-link R and bell-crank lever R to withdraw the act-uatin g-bar from engagement with the pulley S and to oscillate the lever Q to move the clutch into engagement with the driving-pulley.
  • the lower end of the connecting-rod K is shown as provided with a slot within which the pivot-bolt k rests, by means of which said lever K may have vertical movement with relation to the connecting-rod K
  • the bolt will engage the upper end of the slot 7o. Said slot it therefore allows the arm K to be depressed some distance when the clutch isbeing moved into its operative position before the connections between the treadle-arm and roller K are actuated to move the same roller downwardly.
  • Said connecting-rod is provided in its portion containing the slot with an adjusting-plate I0 by which the length of the slot engaged by the pivot-bolt 70 may be varied as desired to correspond'with varying sizes of the roller K and other modifying conditions.
  • the outer or free end of the treadle-arm K is depressed to connect the friction-clutch M with the pulley M said action will withdraw the actuating-bar Q from the recess S of the pulley and the machine will befree to be operated under the action of the applied power until thepulley has completed another rotation, when the brake will operate to stop the machine, at which time the bar will enter the recess in said pulley and permit the lever Q to oscillate t-o disengage the clutch from the pulley M
  • the construction and arrangement of the operative parts of the machine are such that the stop G will stop with the cam g thereon in engagement with the adjacent end of the lever I, by means of which the clamping-jaws B B will always be in their raised position when the machine is not in operation,
  • the operator now depresses the for ward end of the treadle-lever K,which lowers the roller K and throws the machine in operation, by withdrawing the actuating-bar Q from engagement with the pulley S and connecting the pulley M with the shaft M.

Beforeproceeding to describe the machine in detail with reference to the accompanying drawings I will first describe the operation of crimping as performed by said machine by reference to Fig. 1 of the drawings, which is a diagrammatic view in nine sections or parts, illustrating the successive steps of the machine herein described in crimping a sheet of paper. In this view I have indicated in each nine sections simply the upper and lower clamping-blocks, the upper and lower tuckerblades, and the sheet of paper, the sections being lettered in 'eonsecutive order 1 1 1 1, &c., as the operation progresses. Referring now to the first section 1, A A indicate the lower jaws, and B B the upper jaws, the jaw A being stationary and the jaw B having a vertical movement to and from the block A, but no movement laterally thereof. The jaws A and-B are each movable, the jaw B being movable vertically as the block B is movable and the two jaws A B being movable laterally to and from the jaws A and B. O is a sheet of paper, 0 being the rear margin thereof,in which it'is desired to form a flexible section or hinge, which is'made by creasing the same in parallel lines at the points indicated within the brace. (Shown in Fig. 1 D is alower vertically-movable tuckerblade, and D an upper vertically-movable tucker-blade. These same letters will be used throughout the different sections of this diagram. The operation of the machine in this respect is as follows: The tuckers D and D and the upper and lower jaws being separated, as indicated at 1, the sheet of paper 0 is fed between the same a proper distance. The vertically-1novable jaws B and B will now be caused to descend and clamp the sheet firmly upon the jaws A and A and the upper blade D will be moved downwardly and start the bend of the sheet, as indicated at 1". Simultaneously with the completion of this downward movement of the blade D the two jaws A and B will be caused to move laterally toward the jaws A and B, as indicated. As soon as the blade or knife D has merely started the bend in the sheet of paper 0 it is immediately withdrawn, as indicated at 1,
and the jaws A and 13 continue to move to- Ward A and B until they reach the position shown in the diagram 1, in which the sheet will be bent or folded in a downwardly-directed fold with creases at o c 0 The next operation in the machine will be to retract the jaws A B, as shown in the diagram 1, until they are separated to their greatest extent from the jaws A and B and are ready for insertion between them of the lower blade D. The blade D is now caused to move up wardly between the jaws until it comes in contact with and starts an upward bend in the sheet, as indicated in the diagram 1 when it is withdrawn, as shown in the diagram 1 ,and the jaws A B are caused to move laterally toward the blocks A and B, as before. Said movable jaws continue their in ovement toward the jaws A and B and crimp ally, and by the time they have reached their outermost position the jaws B and B have been caused to rise, thus releasing the sheet 0. Suitable feeding mechanism is prot ided by means of which the sheet is moved outwardly until the paper is carried a proper distance to the right, as illustrated in Diagram 1, at which time the upper jaws B B are again moved dowfiwardly to clamp the sheet between the same and the lower pair of jaws, when the operation is repeated as before. This creasing or folding continues until the last crease or bend formed is a pre determined distance from the rear margin of the sheet, thus forming the sheet of paper such as is indicated in Fig. 12 of the drawings.
the jaws B B closed or clamped upon the jaws A A with the sheet 0 between them during the reciprocating or lateral movement of the jaws A 3 against the jaws A and B in order that this double crease, bend, or fold may be given to the sheet before itis fed along the required distance for the next succeeding fold. It may be desirable, however, to go immediately from the operation illustrated in Diagram 1 to that illustrated in 1 and then repeat 1 1 1 1, as stated.
The machine herein shown is so constructed that one of the vertical sets of jaws A and B in this instance is movable laterally toward the other jaw; but it will be apparent that this arrangement may be reversed or that both may move a desired distance toward and from each other. With this explanation of the purpose of my invention and of the essential features thereofto wit, the clamping of the sheet, starting of the bend in the right direction, and then the creasing of the sheet along that bend between the adjacent faces of the crimping-jawsI will now proceed to describe the machine which Ihave constructed to embody this invention.
As shown in said drawings, E designates the frame of the machine, comprising side members consisting of legs or standards E and horizontal top members E said side members being joined together byupper and, lower cross members E E and the standards on each side by intermediate transverse members E E The horizontal top members E are provided with upwardly-extending projections or pillow-blocks E, which form a support for a portion of the operative mechauism, as will hereinafter appear.
For convenience of description the upper jaws or blocks B B will be designated as the clamping-jaws and the jaws AA below as the crimping-jaws, although it will be noted that they will all coact both to clamp the sheet and to crimp it, the clamping action herein referred to being that of engaging and holding the sheets between thejaws in such manner that one set of closed or clamped jaws may be-moved toward the other set or both sets moved toward each other to perform the act of folding or creasing. \Vith this in mind it is believed that no confusion will arise from the arbitrary designation of extend the entire distance between the side members of the frame. The coacting crimping-jaw A is mounted so as to be laterally movable-with relation to the jaw A, but has no vertical movement. present instance supported between the upper horizontal members E of the frame by means of integral tongues e on said frame, which engage grooves in the adjacent edges of the jaw A. The upper faces of the jaws A A lie in the same horizontal plane. The movable crimping-jaw A is adapted to be normally held retracted from the jawAto al low a space between the same for the passage of the tucker-blades D D. The means herein shown for holding such jaw in its retracted position are as follows:
A A designate hollow cylindric bosses mounted on the lower side of the jaw A, 011 each side thereof, adjacent to the frame members E A A designate a second set of 1101- low cylindric bosses mounted on the under side of the jaw A, with the bores thereof in alinement with the bores of said bosses A A A designate short guide-rods mounted in said bosses A A the forward end of said rods with relation to the machine being mounted rigidly within the bosses A and the rear ends thereof having sliding engagement with the bosses A as seen in Fig. 7 of the drawings. The rods A are of less diameter than the bores within the bosses A and are provided adjacent to the forward end of said bosses with rigid collars a, between which and opposing shoulders in said bosses A are interposed spiral expansion-springs a ct.
With this construction it will be seen that when the jaw A is moved toward the jaw Ain the act of crimping it will be moved against the action of the springs a. WVhen the jaw Said jaw A is in the IDS is released, therefore, said springs will act to return the same to its rearmost position, as seen in Figs. 5, 6, and 7.
Any suitable means may be employed for moving the jaw A inwardly upon the jaw A. As herein shown, said jaw is provided on each side thereof adjacent to the frame member E with tappet-blocks A mounted on the lower surface of the jaw. Said tappet-blocks are adapted to be engaged by cam-surfaces 7L, formed on sleeves H, mounted rigidly on a transverse shaft H, which is journaled in the opposite horizontal frame members E of the frame E. Said cam-surfaces are arranged to cause inward movement of the jaw A in each rotation of the shaft H. The shaft H, which may be called the crimping-shaft, extends outwardly beyond the frame E on the lefthand side of the machine, as shownin Figs. 3 and 4, and is provided on the outside of said frame with a gear-wheel H Said gear-wheel is engaged by and receives motion from a smaller gear-wheel M, mounted upon a driving-shaft M and adjacent to the outer end thereof, said shaft M being provided on its opposite end outside of the frame E with a belt-pulley M by means of which the shaft i seavi may receive motion from any suitable source 7 of power.
The bearings within which the shaft I1 is journaled are herein shown as made adjustable to permit the movement of said shaft toward and from the jaw. The frame members are provided with recesses, within which are mounted two-part bearing-blocks H H which are recessed in their adjacent faces to form a suitable bearing for said shaft. The part H of the block is provided in its outer end with flanges 7L2, through which pass securing-bolts H which are mounted in any convenient manner in the frame members E. Lockingnuts h have screw-threaded engagement with the outer ends of the bolts which serve to hold the bearing-blocks and shaft in place in the frame. Between the inner ends of the blocks H and adjacent inner ends of the recesses are mounted buffers H, which permit the necessary movement of said bearingblocks within the recess in the adj ustment of said shaft. A coiled expansion-spring would obviously serve the same purpose and might be used instead of the buffer, if desired.
The movable crimping-jaw A is provided on its upper surface, adjacent to the forward edge thereof, with an adjustable stop, which limits the movement of the sheet of paper when itis inserted between the clamping-jaws.
Said stop consists of a transverse bar B mounted parallel with the adjacent edge of the jaw, and two rearwardly-extending arms B B attached to said bar B adjacent to its opposite end, and adapted to be secured to the upper face of the jaw in any convenient manner. As herein shown, the upper face of said jaw is provided with grooves B B ,within which said arms B rest and slide. Said stops are secured in place upon the jaw by means .of set-screws B B, which pass through the arms B and have screw-threaded engagement with the jaw. In order to provide movement of the stop on the jaw, by means of which the width of the margin of the sheet may be regulated, said set-screws engage elongated slots B B in the arms B The middle portion of the adjacent jaw'B is cut away on its under side to receive the bar B when said bar is at the limit of its movement. WVith this construction the width of the margin of the sheet between the crimped section and the rear edge thereof maybe regulated as desired. A single arm B may be employed to hold the bar B in place instead of two, as shown.
The upper jaws B B are shown in plan view in Fig. 2 and in cross-section in Figs. 5, 6, and '7. Each of said jaws is so mounted as to have vertical movement with relation to the jaws A A, and the rear jaw B is mounted so that it may be retracted from the jaw B when the lower jaw A is retracted under the action of the spring a, as described. Said jaws, as in the case of the jaws A A, extend the entire distance between the upper frame members E but in the construction shown need not be engaged therewith. In order to provide against lateral movement of said jaws B B with relation to the jaws A A said firstmentioned jaws are provided on each end thereof with apertures through which extend upwardly-projecting guide-rods A, which are rigidly secured at their lower ends in the lower jaws A A. Said upper jaws are provided on their upper sides with bosses I), through which the guide-rods A pass, to afford a more substantial bearing for the same. In order that the jaws B B maybe promptly returned to their lower or clamping position when they have been raised sufficiently to allow a sheet of paper to be passed thereunder, spiral expansion-springs X are herein shown as interposed between the upper ends of the bosses b and nuts a on the upper ends of the guide-rods A. With this construction the jaws B B will be lifted against the force of the springs, and when released will be returned to their lower or clamping position thereby in an obvious manner. Said nuts a are made adjustable to permit the tension of the springs X to be regulated and the jaws B B held upon the jaws A A with varying force. Means for raising'said jaws B B to permit a sheet of paper to be passed thereunder are provided as follows:
I I designate two arms or levers pivoted between their ends upon a transverse shaft F, which is non-rotatively mounted between the pillow-blocks E of the frame. To the outer or forward ends of said arms are pivoted connecting-links I,comprisin g parallel side members i and cross-heads t", the lower ends of said side members being pivotally engaged with lugs 12 on the upper faces of the jaws B B by means of pivot pins or bolts. The jaws B B, with which the parallel members of the link are engaged, have lateral movement with relation to each other, and said side members of the link are herein shown as pivotally connected with the cross-head t" by means of pivot-bolts F, by which the lower ends of said side members may be oscillated when the jaw B is retracted from the jawB. This construction also permits said jaws to be raised vertically upward without friction upon the guide-rods A when the rear end of the lever is depressed. When the arms or levers I have been connected with the jaws B B in the manner described, said jaws will be raised from the jaws A A by depressing the rear or free end of said lever I in any convenient manner. This is in this instance accomplished by means of cams g, herein shown as formed on sleeves G, mounted adjacent to each end of a transverse shaft G, which is rotatively mounted between the rear sides of the pillow-blocks E WVhen said shaft is rotated, therefore, the cams Q will act to depress the free ends of the levers I, and thereby raise the jaws B B. When said cams re lease the lever, the springs X will act to promptly return the same to their lower po sition, as shown in the figures of the draw ings. Said shaft G is provided near one end IIO thereof, outside of the frame E, with a gearwheel G which intermeshes with and receives motion from a smaller gear-wheel H, which is mounted on the shaft H outside of the gear-wheel H above mentioned. In order to obviate friction between the free end of the arm I and the sleeve G, said arm is shown as provided with an antifrictionroller 1 The upper blade D is supported upon and actuated by a lever F, which is mounted between its ends upon the shaft F, between said levers or arms I, just described. Said lever F comprises a sleeve F which is rotatively mounted upon the shaft, to which are at tached forwardly-extending divergent arms F and a rearwardly-extending arm F located upon the sleeve centrally of the arms F Connecting-links f are pivotally attached to the forward ends of the arms F to the lower ends of which is pivotally secured the tuckerblade D, as clearly seen in Figs. 7 and 8. Said lever F is so arranged that when in the position shown in Fig. 7 of the drawings the tucker-bladeD will be at the upper limit ofits movement. To move said blade downwardly to crimp the paperbetween the adjacentjaws,'
it is necessary that the rear or free end of the arm be raised. For this purpose the lever F is provided on its rear end with a tappetsurface. f, which is adapted to be engaged by a cam g on a sleeve G mounted on the shaft G. \Vith this constructionwhen the shaft is rotated so that the surface 9' engages the tappet-surface f on the arm F the lever will be oscillated and the blade attached thereto will be lowered between the two sets of jaws and the paper clamped between the same folded downwardly, as before described. The inner faces of the frame are provided with guideblocks 6, Figs. 2 and 8, which are provided with vertical grooves with which the opposite ends of the blade D have engagement and by which they are held from lateral movement. The rear arm F of the lever may be made of sufficient weight to promptly return the blade to its upper position when the cam g leaves the tappet-surface f thereon. I prefer, however, that this movement be positively accomplished and have herein shown for this purpose a spiral spring F mounted upon the shaft F, one end of which is engaged with a collar F on the shaft and the other end of which is engaged-with an arm F extending rearwardly from the sleeve F The spring is so arranged that the lever is oscillated against theaction thereof, and when released the torsional action of the spring will act promptly to return the lever toits normal position and raise the blade upwardly. Said collar F is adjustably mounted on the shaft and may be moved thereon to regulate the tension of the spring as desired.
The lower tucker-blade D is mounted so as to be moved upwardly between the crimpingjaws, and thereby crimp or fold the paper upwardly, as seen at I, Fig. 1. Said blade is trally between the arms J mounted upon and actuated by a lever J,
which is pivoted between its ends upon a transverse shaft J vertically below the-shaft F and mounted in the opposite sides of the frame. Said lever-is of the same form as the lever F above described, comprising a sleeve J to which are attached forwardly-extending divergent arms J 3 and a rearwardly-extending arm J located upon the sleeve cen- To the forward ends of the arms J are pivotally attached connecting-links j, the upper ends of which engage the lower blade D. As herein shown, the blade is provided with slots cl, through which pass the guide-rods A*, as clearly seen in Fig. 5. length to provide for the necessary upward movement of the blade and serve also to support said blade in its lower position. The blade is actuated to move upwardly between the crimping-jaws by depressing the rear end of the arm J 4 of the lever J thereby raising the arms J 3 and the blade thereto attached. In the present instance this is accomplished by the same shaft by which the upper blade is moved downwardly,asheretofore described.
As shown, the rear-end of the arm J of the lever J is provided with a pivotally-engaged actuating-bar J which extends upwardly with its extreme upper end adjacent to the sleeve G The upper end of said arm is provided with a tappet-surfacej ,which is adapted to be engaged by the cam g of said sleeve G through the medium of which the rear end of the lever is depressed and the blade D, attached thereto, raised into its operative position. Said actuating-bai-J is shown in Figs. 4 and 5 as passing through a suitable bearing E in the transverse bar E of the frame, by means of which the upper end thereof is held in engagement with the sleeve G Said lever J is engaged by a spring J which is interposed between the sleeve J 2 thereof anda collar J 7 on the shaft and which acts to positively return the knife to its lower position, as in the construction of the spring F above described. mounted upon the shaft and serves by moving the same upon the shaft to regulate the tension of the spring as desired.
The apparatus herein shown and described is designed for crimping or folding a sheet of paper both upwardly and downwardly, as shown in the diagrammatic view of Fig. 1. It will be seen, therefore, that the cam g operates both tucker-blades D D to move in opposite directions to start the fold on each side of the paper during one rotation of the shaft G and that as each fold is crimped immediately after being started by the blade the shaft H, actuating the movable crimping-jaw A, rotates twice while the shaft G passes through one rotation. The gear-wheels G and H are therefore of such size and the cams g and h are arranged at such angular distance apart on their respective shafts that the crimping-jaw A will be moved inwardly Said slots (Z are made of sufficient IIO Said collar J' is also adjustably at the instant each blade is moving toward and touching to start the fold in the paper, the blade of course being rapidly retracted out of the way of the crimping-jaws as soon as the fold is started in the desired direction. If it be desirable to crimp the paper in but one direction, it will only be necessary to remove one of the tucker-blades and its actu-- ating mechanism and change the size of the gear-wheels H and G the angular relation of the cam-surfaces remaining the same in either case.
As herein shown, the jaws A A l3 l3 do not come incontact with each other when the sheet of paper is crimped between the same, but are provided on their under surfaces with projecting faces a a Z) b which are arranged fore, that the knives be moved beyond the upper and lower planes of the jaws, but only suflicient to clear the said steel faces. Said faces a a Z1 Z2 are shown as made separate from the jaws, but may be formed integral therewith, if desired.
Said frame E is provided in front of the tucker-blades D D with a feed-table E Said table is mounted upon forward extensions E of the upper horizontal bar E of the frame, which are supported from the standards E of the frame by obliquely-arranged braces E Said braces E and horizontal supportingbraces E may be cast integral with the frame E, if desired, and the table E may be made of any suitable material and secured to the frame in any convenient manner.
Between the outer edge of the table and the tucker-blades D D are arranged a pair of feed-rollers K K. In the present instance the casting forming the stationary crimpingjaw A is extended forwardly to slightly beyond the standards E of the frame, at which point it is connected with the table E The upper surface of the table and the casting forming the jaw A lie.in the same horizontal plane, so that the forward portion of said casting forms the rear margin of the feedtable. The lower roller K is mounted in a depression or groove in the forward part of the casting forming the jaw A, so that the upper surface thereof lies in the horizontal plane of the table. Said roller is rotatively mounted at its opposite ends in the opposite side members of the frame. The upper roller K is mounted above said roller K to coact therewith, but in such manner that it may be raised vertically therefrom, so that the sheet of paper may be thrust between the same and between the upper and lower sets of jaws when the said jaws are raised in the manner heretofore described. As herein shown, said roller is mounted at each end in a movable journal-block K which block is mounted be tween upwardly-extendin g parallel guides E secured upon the upper surface of the casting forming the stationary jaw A. lVith this construction the upper roller K may be raised from the roller K to permit a sheet of paper to be inserted between the same and between the clamping-jaws, it being understood that the sheet will be inserted at once between said jaws in such manner that the first crimp made therein will be that adjacent to the front margin thereof, from whence the sheet will be fed forward until the crimped section of the sheet extends to a predetermined distance from the rear margin of the same. The upper roller K is shown in the drawings as in its lower or operative position, but is so mounted that it will normally stand retracted from the roller K, as will hereinafter appear. The means for actuating said roller to bring it into its operative position are as follows:
The coacting portions of the rollers do not extend the full distance between the side members of the frame E, as clearly shown in Fig. 2 of the drawings, but are provided on each end with short shaft-sections which form the journals upon which the rollers turn. Upon the shaft, between the coactin g portion of the roller K and the'side members of the frame, are mounted bearing-links K Said links K pass downwardly through openings in the casting upon which the stationary jaw is formed adjacent to each end thereof and are provided with slots k, adapted to receive the shaft of the roller K, by means of which said links are moved upon the shaft of the roller K when they are moved to raise the upper roller K. To the lower end of said links Kare pivotally attached the forward ends of levers K the rear ends of said levers being pivotally connected with the frameby means of inwardly projecting studs 6 (Shown in Figs. land 5 of the drawings.) Verticallyextending connecting-rods K are pivotally attached to the levers or arms K adjacent to their points of connection with the links K and said connecting-rods are pivoted at their lower ends to the outer ends of arms K, which are rigidly attached at their rear ends to a rock-shaf t a rotativelymounted between the frame members E as seen in Fig. 5 of the drawings. Said rock-shaft e is provided between the arms K with a forwardly-eXtending arm K", to the outer end of which is attached a downwardly-extending connectingrod K which is in turn pivotally attached at its lower end between the ends of a treadle arm or leverK". Said treadle-arm is pivoted between its ends upon a transverse shaft 6 extending between the lower transverse members E of the frame. The outer end of said treadle-arm is provided with a foot-rest K which is adapted to be engaged by the foot of the operator when it is desired to actuate the upper roller. As before stated, the up per roller will normally be held as shown in Fig. 11, in which position sheets of paper may be readily inserted beneath it and in position for crimping. When it is desired to have the surface thereof coact with the surface of the roller K to feed the paper between the same, said roller K will be lowered by depressing the outer or free end of the treadlearm K in an obvious manner. Any suitable means may be employed to maintain the roller K in its normally-elevated position. A preferred form of such means will be hereinafter described. Means for actuating said rollers to feed the paper between the same are provided, as follows:
The upper roller K is provided on one end thereof,at the left hand, as herein shown, outside of the frame E with a ratchet-pinion L, Figs. 2 and 3, said wheel being rigidly secured to the shaft of the roller: L designates a radially-extending arm pivotally mounted on the shaft of said roller K outside of said ratchet-wheel L. Said arm L is provided adj acent to its outer end with a gravity-pawl L adapted to engage the teeth'of the ratchetwheel L. Said pawl is herein shown as directed inwardly from the arm L and adapted to engage the teeth of the wheel L between the arm and the tucker-blades D D. With this construction when the arm L is oscillated toward the knives the pawl will act to turn the ratchet-wheel and attached roller K inwardly, and thus move the sheet of paper between said roller K and the lower roller K outwardly away from the tucker'blades. The means for automatically oscillatin g said roller K as the sheet is crimped is as follows:
L designates an actuating-bar which is pivotally engaged at one end with the arm L and has endwise-sliding engagement at its opposite end with the pillow-block E of the frame. In the present instance said bar L is provided, on its end thereof adjacent said block, with an elongated slot which is adapted to engage an outwardly-extending stud e in said block, said connection being such that the bar L may have free longitudinal movement thereon. Upon the sh aft G, inside of the gearwheel G is formed a cam g so arranged as to engage the adjacent end of the actuatingbar L once during each rotation of the shaft and which acts to move said bar outwardly and to thereby oscillate the outer end of the arm L, which is connected with the baraway from the tucker-blades D D. To the outer end of the arm L is attached a spiral contractile spring L the opposite end of which is attached to an outwardly-projecting stud e on the pillow-block E of the frame. Said spring acts to restore the outer end of the arm L" to a vertical position after it has been oscillated by engagement of the cam with the inner end of the actuating-bar, as herein described, and by reason of the engagement of the pawl with the ratchet-wheel, as shown, the spring will act to turn said ratchet-wheel and attached roller K inwardly in the manner before described. Any suitable means may be employed for attaching the outer end of the connecting-rod L with the radial arm L. As herein shown,said arm is provided on its outer face with a T-slot Z, within which is adapted to rest and slide a correspondingly-shaped pivot-stud Z, with which the outer end of the actuating-bar L is pivotally engaged. Said stud will be adjustably secu red to thearm L in any suitable manner. When the stud is moved upwardly or downwardly in the slot Z,
the throw of the arm L will be decreased or in creased and the length of the feed of the paper between the rollers K K correspondingly changed.
The ends of the shafts opposite theparts just described are operatively connected together by nieans whereby the upper roller is given a positive rotary motion in the desired direction and at the desired speed. The details of such mechanism are shown in Figs. 2 and 11. In said figures, k designates a gearwheel mounted on the shaft of the roller K, and k a gear-wheel mounted on the shaft of the roller K. Said wheels are adapted to mesh with each other when the roller K is in its lower position, but are moved out of contact with each other when said roller is lifted. Said wheels are maintained in constant operative relation by means of two intermediate gears 10 mounted on short shafts 7.: 7a, which latter are mounted between side plates or links 70 9. Said gears 70 mesh with each other and with the gears [o k and are connected with the latter by means of side plates or links In, mounted at their opposite ends upon the shafts k k and the shafts of the rollers K K. The upper link 70, or that engaging the shaft of the roller K, is pivotally mounted upon the shaft 7. so that the outer end thereof may swing upwardly to permit upward movement of the attached roller K.
The machine thus far described is operative to crimp sheets of paper in the manner hereinbefore set forth. The tucker-blades will each act to start the fold or crease in the paper once in each direction during each revolution of the shaft G. The movable crimpingjaw will act to crimp each fold. The clampingjaws will be raised once during each revolution of the shaft G, and said shaft will act through the cam-surface g to actuate the rollers K K to advance the sheet between v the jaws. When the clamping-jaw B descends upon the jaw A after a crease or fold has been formed and the sheet is fed along for the next fold or crease, the sheet is flat- The sheet of paper in Fig. 12 is shown as provided with ten creases or folds, and the machine herein shown will be considered as designed for crimping a sheet in such manner in one continuous operation thereof. The machine may of course be set to produce any greater or less number of folds or creases desired; but in any case it is desirable that the machine may be automatically stopped when the predetermined number of creases or folds have been produced. To accomplish this result mechanism is provided, as follows: a
M3 designates a pulley mounted rigidly on the shaft M and, as herein shown, on the end thereof adjacent to the gear-wheel M.
N designates a friction -brake'comprising two jaws N N, which are divergently curved at one end thereof to embrace the pulley M as more clearly shown in Fig. 5 of the drawings. Said arms are pivoted at their lower ends upon a stud E extending inwardly from the frame E, adjacent to the pulley M and are adapted to oscillate toward and from each other in a vertical plane. The parts of said arms adjacent to the pivotal point of connection with the stud E are provided with an aperture which extends from front to rear of the machine, and within said apertu re is arranged a clampingbolt or pin 01, provided on one end with a shoulder, herein shown'as formed by locking-nuts n, and is engaged at its other end with a lever N which is arranged with its fulcrum on the arm N of the clutch opposite that with which the nuts n are engaged; Said lever acts, in connection with the pin a, when the lower end thereof is oscillated away from the pulley, to draw the arms of the brake together and clamp them upon the pulley m The lower ends of the jaws N are provided on opposite sides thereof with bearing-blocks 91 which may be made integral therewith or not, as desired, and with which the nuts n and lever N are engaged. Said lever is herein shown as provided with an inturned end portion 71 the extreme inner end of which engages the adjacent bearingblock a and forms the fulcrum of the lever. \Vith this construction the point of fulcrum on the bearing-block 02 moves downwardly as the lower endof the lever is moved outwardly away from the pulley, so that the point of application of power of the clampingpin '11 remains in the same horizontal plane. The upper or bent end portion of the lever N is bifurcated, and between the arms thereof the outer end of the clamping-pin it rests and is secured therein by means of a pivotbolt 07.
N designates a spring which engages at one end the lower end of the lever N and is attached at its other end to the frame, by means of which the lever is returned to its normal or non-clamping position when released.
O designates a shaft rotatably mounted below the shaft M and slightly in the rear thereof. Said shaft is provided on its outer end with a large gear-wheel O, which intermeshes with and receives motion from a small gearpinion P, mounted upon a sleeve P, which is rotatively mounted upon a stud P extending outwardly from the frame E above and in front of the shaft 0 said sleeve P being provided outside of-the wheel P with a second gear-wheel P, which intermeshes with and receives motion from a gear-wheel M on the outer end of the main shaft M. It will thus be seen that the connection between said main shaft M and the shaft 0 is such that said shaft 0 will be caused to rotate very slowly with relation to the main shaft. Said shaft 0 is provided adjacent to the lever N with a sleeve 0 on which is formed a cam 0, as shown in Fig. 5 of the drawings. Said cam, as herein shown, rotates from right to left and engages the lever N to gradually force the lower end thereof rearwardly, and thereby tighten the brake N upon the pulley M which gradually stops the rotation of the shaft M and the movement of the parts of the machine connected therewith. The shaft 0, carrying the cam 0, rotates very slowly with relation to the driving-shaft M, and said cam acts to gradually retard the movement of the shaft and the parts connected therewith. Said parts are so arranged that when the cam is exerting its greatest power upon the lever, or is in that position in which a line passing through the same and the center of the shaft extends at right angles to the lever N said lever will act with such force upon the brake N as to positively stop the movement of the shaft M and the parts operatively connected therewith.
The shaft M is provided on its outer end adjacent to the driving-pulley M with a friction-clutch M by means of which said pulley M is connected with the shaft M in the usual manner. As the shaft M is stopped gradually by the friction-brake N the clutch is so mounted upon the shaft as to permit it to slip somewhat thereon when said brakeN is set upon the pulley M Said clutch is adapted to be disconnected from the shaftat a time slightly in advance of the moment when the lever N is exerting its greatest power upon the brake N to stop said pulley- M and shaft M, connected therewith. Said clutch is actuated by means of a lever Q, which is engaged at one end with an annular groove in the clutch and is pivoted between its ends upon a bracket Q, extending outwardly from the frame of the machine. The lever Q is engaged at its lower end with a spring Q which is attached to the frame of the machine and which acts through said lever to normally hold said clutch out of engagement with the pulley M Said clutch is held positively in its operative position, or that in which it acts to connect the pul ley M with the shaft M, by means of an actuating-bar Q connected with the lever Q below'its point of pivotal attachment with the bracket Q, and adapted to be engaged at its opposite end with a suitable guide-surface upon the shaft 0. Said guide-surface is so formed as to hold the bar and connected lever in their outermost positions during the greater part of the rotation of said shaft; but at a given time in the rotation thereof it permits said bar to move endwise toward the guidesurface, and thereby allows the lever Q under the action of the spring Q to be oscillated to move the clutch M out of engagement with the pulley M Said guide-surface in this instance consists ofa segment mounted upon the shaft 0 adjacent to the cam-sleeve O Said segment, as herein shown, is made in the form of a pulley S, provided in its periphery with a recess S, within which is adapted to enter at a given time in the rotation thereof the adjacent end of the actuating-bar Q The cam 0 of the sleeve 0 and the recess S in the pulley are so arranged upon the shaft that said recess will be moved into the plane of the bar Q just before the cam 0 is exerting its most effective power through the lever N 2 upon the friction-brake N, so that at the instant the actuating-bar enters the said recess of the pulley and permits the lever to oscillate and actuate the clutch to disconnect the pulley M from the shaft Mv the brake mechanism will act to positively stop the movement of the shaft M and the parts of the machinery operatively connected therewith. The recess S is made slightly wider than the thickness of said actuating-bar Q and the peripheral speed of the pulley S is such that the brake will act to entirely stop the machine before the bar Q comes in contact with the sides of the recess. \Vith this arrangement no strain whatever comes upon said bar when stopping the machine. The inner end of the bar Q is provided with an antifriction-roller Q by which friction between the same and the pulley is obviated in the rotation of said pulley.
The clutch will be held in its retracted position by the spring Q and will be moved inwardly against the action of said spring to connect the pulley with the shaft when the actuating-bar Q is disengaged from the recess in' the pulley S. Said actuating-bar is herein shown as connected with the rear end of the treadle-arm K in such manner that when the forward end of said arm is depressed the bar will be' withdrawn from the recess S and the clutch moved to connect the pulley with the shaft M, as before described. The actuating-bar Q is connected with the rear end of the treadle-arm K by means of a bellcrank lever R, pivoted at its angle upon a bracket R, which projects inwardly from the frame E. The arm of said bell-crank lever adjacent to the treadle-arm is operatively connected therewith by means of a connecting-link R and the opposite arm of the lever is operatively connected with the bar QZas shown in Fig. 4c. Said bell-crank lever R is so arranged that when the actuating-bar connected therewith is in its innermost position or engaged with the recess S of the pulley S the rear end of the treadle-arm K will be depressed and the outer end thereof elevated, at which time, as before stated, the clutch will be disengaged from the pulley M When, therefore, the forward end of the treadle-arm K is depressed, it, will act through the connecting-link R and bell-crank lever R to withdraw the act-uatin g-bar from engagement with the pulley S and to oscillate the lever Q to move the clutch into engagement with the driving-pulley. With this arrangement it will be seen that the spring Q tends, through the connection described,- to normally depress the rear end of the treadle-arm K and raise the forward end thereof, which will, through its connections with the roller K, act to raise said roller away from the roller K. Said treadle-arm therefore serves the double purpose of actuating the roller K to move it into its operative position with the roller K and to operate the mechanism by which power is connected with the machine. As the move ment requiredto lower the roller K is less than that necessary to move the clutch M through its connection with the lever, into its operative position, the lower end of the connecting-rod K is shown as provided with a slot within which the pivot-bolt k rests, by means of which said lever K may have vertical movement with relation to the connecting-rod K When the clutch M is disconnected from the power-pulley M as before stated, and the free end of the lever is in its raised position, the bolt will engage the upper end of the slot 7o. Said slot it therefore allows the arm K to be depressed some distance when the clutch isbeing moved into its operative position before the connections between the treadle-arm and roller K are actuated to move the same roller downwardly. Said connecting-rod is provided in its portion containing the slot with an adjusting-plate I0 by which the length of the slot engaged by the pivot-bolt 70 may be varied as desired to correspond'with varying sizes of the roller K and other modifying conditions. \Vhen the outer or free end of the treadle-arm K is depressed to connect the friction-clutch M with the pulley M said action will withdraw the actuating-bar Q from the recess S of the pulley and the machine will befree to be operated under the action of the applied power until thepulley has completed another rotation, when the brake will operate to stop the machine, at which time the bar will enter the recess in said pulley and permit the lever Q to oscillate t-o disengage the clutch from the pulley M The construction and arrangement of the operative parts of the machine are such that the stop G will stop with the cam g thereon in engagement with the adjacent end of the lever I, by means of which the clamping-jaws B B will always be in their raised position when the machine is not in operation, and
desired. The operator now depresses the for ward end of the treadle-lever K,which lowers the roller K and throws the machine in operation, by withdrawing the actuating-bar Q from engagement with the pulley S and connecting the pulley M with the shaft M. The instant the machine begins its operation the cam g leaves the lever I and the clampingjaws are moved by the action of their actuating-springs to their lower or clamping position. The tucker-blade is now actuated by the means described and the crimping-jaw moved inwardly to crimp the folds or creases, as described in connection with said constructions. The rollers are actuated at each rotation of the shaft G to advance the paper so as to present a fresh surface for the next succeeding fold or crease. In the machine described the shaft G will rotate five times during one rotation of the'shaft 0, while the shaft H will move through ten rotations during such time. If a larger or smaller number of folds or creases are desired in the sheet, the relative speeds of the shafts H and G to the shaft 0 will be changed accordingly. When the last crimp has been made in the sheet, the brake N will operate to stop the machine, the bar Q will be thrown into engagement with the recess S of the pulley S, and the clutch M disengaged from the pulley M when the machine will be stopped. The sheet of paper will now be withdrawn and a new one inserted, when the operation will be repeated.
The operation of the machine after the paper has been inserted and the lever K depressed is, as will be seen, entirely automatic and requires no supervision from the operator until the sheet is ready to be withdrawn and a new one inserted therein.
