MACHINE FOR BUNDLING SHEETS OF UNB OUND BOOKS.

SPECIFICATION forming part of Letters Patent No. 453,312, dated June 2, 1891.

Application filed June 11,

To all whom it may concern.-

Be it known that I, EDWIN CEAWLEY, Sr., a citizen of the United States of America, and a resident of the city of Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Machines for Bundling the Sheets of Unbound Books, of which the following is a specification.

The several features of my invention and the advantages arising from their use, conjointly or otherwise, will be apparent from the following description and claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a vertical transverse sect-ion of the machine, taken at the dotted lines 00 w of Fig. 1, looking from right to left. Fig. 3 is a vertical transverse section of the machine, taken at the dotted line y l/ of Fig. 1 and looking from left to right. Fig. at represents a vertical transverse section of the machine, taken at the dotted line 2' z of Fig. 1, looking from left to right, showing the yoke-piece and its connecting-rod. Fig. 5 is a top or plan view of the plunger-bar. Fig. 6 is an elevation of the flanged end, or, more properly, the side of the head of the plunger-bar as it is seen in Fig. 1, in looking from left to right, when the grooved plates adjacent to said plunger-head have been removed. Fig. 7 is an elevation of the grooved side of that plate which is secured to the front side or end of the plunger-head, the grooves facing the lefthand end of the machine. Fig. 8 is an elevation of the grooved side of the plate which is at the left-hand end of the machine, the grooves of said plate facing toward the righthand end of the machine. Fig. 9 is an elevation of certain details of my invention, and showing more particularly the crankshaft, journal-bearings therefor, and pawl, together with the rod binding the journals together, and showingin section the rods upon which the crank-shaft journals are supported, also showing in section the plunger-bar, and also showing in elevation the lever which operates the said crankshaft, the view being taken at a point in the longitudinal axis of the machine to the left of said device. Fig. 10 is a side elevation of the crank-shaft by itself. Fig. 11 is an end View of the said crank-shaft, said view being taken at the right hand of Fig. 10, looking toward the left. Fig. 12 is a detailed view of that end portion of the trigger-rod shown at the left hand in Fig. 1, and showing in section the adjacent portion of its supporting-frame.

The frame-work of the machine consists, in general, of two transverse supporting-plates and two connecting-bars. One of these supporting-plates (indicated by the letter A) is at one end of the machine and the other vertical transverse supporting-plates B is at the other end of the machine. These plates A and B are rigidly connected together by two parallel horizontal bars 0, one of these bars being at one side of the machine and the bther at the other side of the machine, substantially as shown in Figs. 1 and 2. This skeleton frame work is suitably supported, preferably on legs A, as shown. These legs are braced by braces A A to withstand the strains to which the frame is subjected. The left-hand portion of this machine is provided with the receptacle D, into which the booksheets to be pressed are placed. The sides of the receptacle may be open or closed. The sides are preferably formed of the parallel bars (1'. One of the rods 0 of the frame also preferably contributes to completing one side of the receptacle. Two of these rods cl also perform the further function of tying the right-hand end (Z of the receptacle D to the left-hand end, forming plate A of the machine. The rods which perform this function are the lowest rod (1 and the upper left-hand rod cl, (shown in Fig. 2, and also seen in Fig. 1,) said rods being suitably secured in position by nuts (1 The shape of this receptacle D in cross-section is rectangular, the bottom angle of the receptacle being at the bottom portion of the main frame of the machine, and for the purpose of enabling the book-sheets to better stand on edge in the machine, and also for the further purpose of lowering the position of the sheets in the machine, the bottom angle of the receptacle is at the rear of the 1011- gitudinal central plane of the machine. The object of thus lowering the sheets in the machine is to enable the plunger to directly operate upon the sheets at a point nearer their center without unduly elevating the plungerbar and its head in relation to the other parts of the machine and thereby necessitating extra mechanism for holding the plunger at the same elevated position or unduly lowering the receptacle and thereby complicating the construction of the machine in this direction. I accomplish these purposes in a very simple manner by shifting the bottom angle of the receptacle past the vertical longitudinal center of the machine, substantially as shown in Fig. 2. \Vithin this receptacle moves the plunger-head E, whose face is parallel to the face of the end pieces A and B of the frame. The outlines of this plunger-head conform in shape to the inner frame in crosssection of the receptacle D, with the exception that the bottom of the plunger-head is provided with an extension (2, which extends downward and is provided with an opening e Through this eye or opening e the lowest tie-rod d passes, and this last-named rod serves as a guide and a support for the plunger-head as the latter is reciprocated in the trough or receptacle D. This plunger E is actuated by the plunger-bar a This plungerbar e is supported and slides in a recess or opening e in the plate 01 forming the righthand end of the receptacle D, and also is supported by and slides through an opening e in the frame-plate Bof the machine. The upper surface of this plunger-bar e is provided with a toothed rack c, the faces of the teeth being so arranged that they shall be properly operated in the well-known manner by the pawls hereinafter described.

Pivoted to a suitable portion of the frame, preferably to the end plate B, are two pawls 1) b Both of these pawls are arranged to engage with the rack e of the plunger-bar e but the length of these pawls and their position is substantially as shown and such as to cause one of the pawls to engage the rack when the other pawl is half-way between two adjacent teeth. By these means and by this arrangement I am enabled to hold the plunger-bar and its plunger-head against the elastic resistance of the compressed book-sheets at shorter intervals of progression. When desired, one of the pawls b b may be dispensed wit-h, and the machine will yet be operative; but the pressure of the plunger-head cannot be so closely adjusted against the bundle.

For the advancement of the plunger-bar e and its head E, I provide the following mechanism: A crank-shaft F is jonrnaled at each end in the journal-boxes f f. These journal-boxes are respectively fixed upon their respective adjacent bars C of the frame. These journal-boxes are kept in avertical position by suitable means, preferably by means of the tie or brace red f substantially as shownin Fig. 9. The crank-shaft F is centrally provided with the cranks or lug-pieces f f, and between these lugs f" is placed a pawl f This pawl is pivotally connected to To one end the lugs f at a point f thereon.

of the crank-shaft is rigidly attached the operating-lever f. As will be observed by reference to Fig. 1, the relative positions of the pivoted point of connection between the pawl and itslugs are such in relation to the lever that when the lever f is lifted and thrown back the pawl f is out of engagement. The manner wherein this pawl f is elevated is shown in Fig. 11, where the pawl is shown in dotted lines. As the lever f is elevated the shaft turns in the direction of the arrow (see Fig. 11) and the middle portion of the pawl will be caused to rest upon the crank-shaft F, and the point of the pawl will be thrown up and out of engagement with the rack. \Vhencver the lever f is moved inacontrary direction-viz., from right to left in Fig. 1-- the shaft F will be rotated in a direction contrary to that shown by the arrow in Fig. 11, and consequently the point of the pawl f willbe lowered and come into engagement with the rack e of the rack-bar c. When the lever f is not in use, it is in the position shown in Fig. 1 and itleans past theperpendicular to the right. This inclination of the lever preventsit from falling forward and striking the operator. In order to uphold the lever and preventit, after being inclined to the right of the perpendicular, as shown in Fig. 1, from falling down toward the right-hand end of the machine, there is provided a lug f, (see Figs. 1 and 9,) which is rigidly attached to the journal-box adjacent to the said lever f The lower end of the leverf is likewise provided with alugf which, when the lever is inclined as shown in Fig. 1, engages the lugf on the journalbearing and stops any further movement of the lever toward the right of the machine. As the lever f is moved from right to left the point of the pawl, as aforementioned, descends and engages with the rack, and as the lever is continued to be moved the pawl will operate to press the plungenbar e to the left. By continued reciprocating movement of the lever f 5 the rack-bar is moved forward until the plunger-head is stopped by mechanism hereinafter specified, or, if the receptacle contain a bundle of book-sheets, until the plunger-head impinges against the bundle of sheets, and the resistance of said sheets prevents the plunger-head from being moved any farther from right to left. In the meantime all backward movement of the bar 6 is prevented by means of the supplemental pawls 1) b hereinhefore mentioned. In order to prevent the lever f when moved forward, from descending below a horizontal position, it is provided with a lugf", and upon the descent of the lever from right to left to a horizontal position this lugf will impinge against the aforementioned lug f on the journal-bearing and prevent further descent of the lever.

For convenience of operating the plungerbar in connection with the supplemental pawls 1) I1 I have provided a novel mechanism, which I will now describe. Beneath the lower pawl b is placed a lever, pivoted at b IIO end plate B of said frame. said lever lies directly below and in proximto the frame, and preferably to the upright One arm Z) of the ityto the lower pawl 19 and the other arm 19 of said lever extends downward in a nearlyvertical position. is connected a spring or weight, preferably the former, whose tendency is always to press the arm 19 from right to left, and thereby elevate the arm b of said lever. A preferred arrangement of mechanism for this purpose consists in the spring I), strained from a fixed point, as 6 on the journal-box. To this lower arm b of the lever is also connected a push-rod b the free end of this push-rod being preferably provided with a handle b. The rod is also provided with a notch or catch b in its under side and astop Z7 The notch Z7 is arranged to engage an edge Z7 of the frame-plate A. The pin or stop 12 prevents the push-bar b from being thrown too far from right to left by the action of the spring I). The movement of the rod 12 from left to right is properly limited by the plate B, against which the right-hand end of the rod 19 impinges. When the rod 11 is pushed from left to right, the notch Z1 engages the lip or edge b of the frame. The spring I) is strained and the lever-arm b is depressed and allows the pawls b b to fall and engage with the rack e of the plunger-bar 6 as heretofore mentioned. As the movement of the rod 19 from left to right is limited by the plateB of the frame, the leverarm I), after dropping the pawls 1) b does not descend far enough to engage itself with the rack e of the plunger-bar e and remains stationary at a point between the pawl 19 and the rack 6 The rod 5 and its free ends e e are allowed to remain in this last-named position while the operator is actuating the main lever f and advancing the plunger-bar and plunger-head against the bundle of sheets lying within the receptacle or trough D. Af-

ter a bundle of sheets has been tied, as hereinafter specified, it is desirable to retract the plunger and plunger-bar from left to right in order to remove the tied bundle of booksheets and place the machine in readiness for the reception of the new set of book-sheets to be duly tied into bundles. In order to loosen the pawls 19- b it is necessary for the operator to employ his Weight and energy.

NVhen the pawl f is in engagement with the rack e, the free end of the main lever f will be depressed, as aforementioned, from right to left and will be located somewhere at the" b 12 must be continuallyupheld by the operator while the plunger-bar e is being re- To this arm 12 of the lever tracted. Otherwise the pawl 12 or b will pre- Vent the further retraction of said plungerbar 6 My device, consisting of the rod b levers b 19 and spring 19 obviates these difficulties and disadvantages, and at this point in the operation of the machine comes into active use.

Its operation is as follows: The operatordisengages the notch of the bar 19 from the lip or edge Z9 of the frame A, and the tension of the spring 1) moves the bar 11 from right to left, carrying with it the lever 19 and lifting the lever 19 until the latter impinges against the pawl W. The pressure of the plunger-bar e upon one of the pawls b b according as one or the other is in engagement with the rack 2 prevents the spring I), through the agency of the levers 12 b from raising the pawls b b at this juncture. The operator, pressing down the lever f, as aforementioned, relieves the pressure of the bar upon the engaged pawl Z) or 12 and thereupon the pressure of the spring I), exerted through the lever b raises the pawls b 12 away from the rack e". At this point in the operation of the device the pin Z1 comes into play and limits the movement of the rod 12 from right to left,

and for the same reason limits the elevation of the arm I) and constantly limits the elevation of the pawls b 6 leaving them in a con- Venient position for readily engaging with the rack e when the arm or rod 19 shall be moved from left to right and the notch 12 may be engaged with the lip or edge 11 of the frame.

The operator now lifts the lever f thereby releasing the pawl from engagementwith the rack e, and the plunger-bar is now free to slide from left to right and to return to its original position, the plunger-head E being at or near the plate (1 of the receptacle D. It may be here remarked that in order to limit the movement of the plunger-bar e from right to left and prevent the right-hand end of the bar from passing through and out of the plate B of the frame I provide suitable stops. When the lever f is elevated .and its pawl f is out of contact with the plunger-bar, I provide a suitable stop 6''. This prevents the plungerbar from being drawn through the plate 13 by hand. To prevent the right-hand end of the plunger-bar from being carried through the plate B by powernamely, by means of the operation of the lever f and the pawl j -I provide on the plunger-bar e a blank space (2 between the forward portion e of the rack e and the rear portion a of the rack e When the right-hand end of the plunger-bar has nearly reached the plate B, the point of the pawl f 3 reaches the blank space 6 and farther movement of the plunger-bar e from right to left through the agency of the pawl f is impossible. It is desirable to adj ust the pressure of the plunger against the bundle of book-sheets to as fine a degree as possible. For this reason the teeth on rack. e are preferably finer and closer together than on the forward rack e Were it not for this construction it would happen that when the operator had almost fully compressed the bundle of sheets and could advance by lever f the plunger for the distance of only one-half a tooth of rack e he could notv take advantage of this advance, but would have to let the rack slide back said onehalf tooth, thereby leaving the bundle not fully compressed.

In order to facilitate the application of the string to the bundle of book-sheets while under the pressure of the machine, I make use of the well-known means heretofore employed for similar purposes. These means are as follows: A block I-I, adapted to set within the receptacle D in the position shown in Fig. 1, has provided on that one of its faces which is toward the left-hand end of the machine a double series of grooves h, one series of grooves crossing the other series at right angles. These grooves are of a sufficient size to readily allow the passage through them of the string or cord with which the bundle of book-sheets in the press is to be tied. This block II is preferably provided with a handle 7L2. This block II is then bolted to the plunger-head E. The handle 71.2 enables the plunger-head E and the plunger-bar e to be readily reciprocated by hand.

K indicates a block which is complementary to the block II aforementioned. This block K is similarly provided with two series of grooves h, crossing each other at right angles and of sufficient size to admit the passage of the string or cord with which the bundle of book-sheets in the press is to be tied. The block K is located in the left-hand portion of the receptacle D, and its grooves face toward the righthand end of the machine. Preferably this block is not fastened to the end plate A of the machine, but is movable toward the right. It is made movable for the following reason: In order to economize space and to enable the machine to be operated in a smaller compass, the plunger-bar e is made only of such a length as that the plunger-head with its block II can come only to the middle of the receptacle Dna1nely, the point shown in dotted lines x a: of Fig. 1. Ordinarily any bundle of sheets that may be tied in this machine will occupy more than onehalf of the receptacle D. In case, however, the bundle of sheets to be tied occupies less than one-half of the receptacle D, the block K is moved forward and a suitable block of wood or other suitable material is to be placed between the plate A and the block K, thereby advancing it sufficiently to enable the plunger-head E to exercise a proper amount of pressure on the bundle of sheets to be tied. fore it not for the fact that the block K is movable, the plunger-bar 0 would have to be made much longer, and consequently the working-space occupied by the machine in a room or factory where it is operated would be much greater.

I will now describe in general the mode in which my machine operates.

The plunger-head being at or near the righthand end of the receptacle D and the block K having been properly adjusted, as afore-' mentioned, the operator sees that the notch b of the rod b is in engagement with the lip or edge I) of the frame A. A sufficient quantity of booksheets is placed on edge within the receptacle D. In case the sheets are folded sheets the folded edge which is to form the back of the book is placed on the side L of the receptacle D, while the folded edge that is to form the head or top of the book rests against the side M of the receptacle D, the leaves being readily and quickly adjusted so that their respective edges are in line. The operator now seizes the handle and rapidly draws the plunger-head and block IIinto contact with the adjacent head of the bundle of book-sheets. He then reciprocates the lever f and, through the agency of the pawl f, further advances the plunger-bar e and the head E, with its block II, thereby compressing together book-sheets in the receptacle D to the desired degree. He now passes the cord or string with which the bundle is to be tied around the bundle of sheets to be tied, and in accomplishing this result he passes the cord through one of the grooves of the block II and one of the grooves of the block K. Having securely tied the bundle together in the ordinary manner, he now disengages the notch b of the rod 1) from the lip b of the frame A. He now applies power to the lever f until the pressure of the plunger-bar a upon the pawls 1) according as one or the other is in engagement with the rack e ,is relieved. The pawls b b rise out of contact with the rack a, leaving the plunger-bar free to be moved back from left to right by hand. The operator thus moves backthe plunger-bar head and block II by means of the handle 7L2 to a position in proximity with the right-hand end of the receptacle. He then removes the tied bundle of sheets from the receptacle and again proceeds to repeat the aforementioned operation. In this way the desired number of book-sheets are successively tied.

lVhile the various features of my invention are preferably employ ed together, one or more of them, so far as applicable, may be employed without the remainder.
