To all whom it may concern.-

Be it known that I, ROBERT BURNET, a citizen of the United States, and a resident of East Orange, Essex county, and State of New Jersey, have invented new and useful Improvements in Bookbinding Machinery, of which the following description, taken in connection with the drawings herewith accompanying, is a specification.

My invention relates to that class of machinery adapted for binding booksthat is, securing the sections forming the filling of the book to the back of the cover by means of staples; and the invention consists, first, in the means for feeding and driving the staples; second, in the means for operatingor feeding the table upon which the book to be bound-is secured, and in the means for adjusting the movement or feed of the said table, and, third, in the construction of detail parts used in combination with and forming a part of the machine as a whole, in a manner as will hereinafterbe described in detail, and pointed out in the claims.

The object of my invention is to provide a machine of few parts, of cheap and simple construction, and provided with the proper means for all necessary adjustments, that will perform the desired function in the quickest, easiest, and best manner. Hence my invention.

Referring to the drawings, Figure 1 represents a front view of my improved machine; Fig. 2, a side view showing the book secured thereon in proper position to be operated upon; Fig. 3, a sectional view through line a; m of Fig. 1; Fig. 4, a plan view with the staple feeding and driving mechanism and the booksupporting table removed; Fig. 5, a side view of one of the staple supporting and feeding devices detached from the machine; Fig. 6,a plan view of the same, and Fig. 7 a cross-seetion through linezz: 0c of Fig. 5; Fig. 8, a front view of one of the staple-driving devices; 45 Fig. 9, a top view of the same, and Fig. 10 a sectional view through line a; x of Fig. 8. Fig. 11 is a diagram of portion of the back of a book with sundry leaves secured therein in the manner practiced by my machine, the

50 view being taken in section through one of the fastening-staples.

In the drawings, A represents the main supporting frame or stand.

B is a hinged or movable frame for the support of the staple feeding and driving mech- 55. anisin supported above the main frame A and pivotally connected or hinged at its rear end with the back of the frame A or a part thereof at a and at its forward end supports the said staple feeding and driving mechan- 6o ism, which consists of a supporting-plate 0, (see Fig. 10,) by which the several operating parts forming the said staple feeding and driving mechanism are supported. The plate 0 is provided with a flange or projection c on its rear side adapted for dovetail connection with the forward end of the frame B, as more clearly shown in Fig. 3. A section 0 of saidflange or projection c is detachable and adjustably held in position or connection with the plate a by means of a set-screw 0 in order to allow the said section 0 to be detached or disconnected from the plate 0 and allow the latter, with the several parts supported thereby, to be drawn forward and from its connection with the frame B in a manner as will be readily understood bythose skilledin the art and for the purpose of adjusting the position of said devices on the frame B or for any other desired object.

0 represents a guid eplate adj ustably supported at a point below the plateo and in line therewith on the end of two rods or plungers 0 0 supported and adapted to slide in holes in the supporting-plate c, and is provided with a vertical centrally-arranged groove or guideway c in its rear side, adapted to receive the staples f from a feed-rod c and guide the same in a manner as will hereinafterbe set forth. The said feed-rod 0 (shown in detail in Figs. 5, 6, and 7) is secured at one end of the rear side of the guide-plate c with its upper edge, on which the staples are placed and fed from, central with and adjacent to the said guideway c in the plate 0 5 and extends from the latter at an upward inclination, in order that the staples may slide when released by their feeding device into the guideway c, in which place they are adjustably held until engaged by the stapledriver 0 by a spring a", which is secured on the end of the feed-rod c and at its free end projects across the said guideway c to yieldingly support the staple until engaged by the staple-driver. The upper edge or section of the feed-rod, which is slightly reduced in size in the instance shown for the reception of the staples, is provided with a detachable box-like cover a which is adapted to be slid thereon and be retained in position by groove and counterpart connection, as clearly shown in Fig. 7, a sufficient space being left between the feed-rod and the said cover for the ready admission and passage of the staples, the object of the cover being to prevent the staples from being displaced from their position on the feed-rod when the machine is in operation. The staples are adapted to be placed in quantities upon the said feed-rod at its upper free end, and be fed therefrom one at a time into the guideway c by means of a feeding device consisting of a supporting rod or frame 0 pivotally secured to the said feed-rod at c and provided at its front end with an arm or shaft o extending at right angles thereto and over the feed-rod for the support of a feeding-roll 0 which latter is adapted to be held in engagement with the upper edge of the feed-rod through an opening in the cover 0 as more clearly shown in Fig. 5, by means of a spring 0 which is secured to the feedrod and engages with and exerts an upward pressure on the pivoted supporting rod or frame 0', and thereby holds the feeding-roll supported at the opposite end of the latter in engagement with the feed-rod and prevents the staples from sliding therefrom into the guideway 0", except as fed by said feedingroll. The space between the teeth orprojections on the said feeding-roll is of sufficient width for the admission of the top of a single staple, in order that the roll, when moved or rotated the distance of a single tooth or projection, may release one of the staples and allow it to slide down into the guideway 0 A frame carrying a pawl e for engagement with the feeding-r0110, is hinged on the said arm or shaft o and is adapted to be engaged at its outer end by the forward end of the frame B, (when the latter is lowered,) thereby drawing the end of the pawl back into engagement with the next preceding tooth orprojection 011 the feeding-roll. When the frame B is again raised from contact with the frame 0, the latter is raised or moved back to its normal position by means of a spring 0 which exerts an upward pressure on the same, and the pawl e is caused to move or rotate the feeding-roll sufficiently to release another staple. As the feeding-roll is moved or rotated by the pawl 0 it is retained or held by a spring pawl or catch 0 which latter is secured on the supporting rod or frame c. The several engaging or contacting ends or parts of the supporting rod or frame 0 and hinged frame 0 are provided with adjustingscrews, as more clearly shown in Figs. 5 and 6, adapted to adjust and allow for any undue wear of the several engaging parts.

D represents the table upon which the book to be bound is adapted to be secured, and is supported and adapted to slide or operate in suitable bearings or ways on the frame A. The said table is provided on its under side with a series of teeth or projections (1, adapted to be engaged through an opening in the top of the stand A, as shown in Fig. 3, by apawl d, which is pivotally supported on the upper end of a pivoted vertically-arranged rod or lever (P, which latter at its lower end is bifurcated and embraces a cam or eccentric 01 located on a rocking shaft (1 The latter is operated in the instance illustrated in one direction by a foot-lever (I through the medium of a segment or arm d having a rigid connection with the shaft (1 and a connecting-rod 01 and in the opposite direction is operated by counterbalance-weights d d A second stationary pawl or catch d is pivotally supported at one side of and adjacent to the said operating-pawl d, (see Fig. 4,) and is adapted to engage with the said teeth or projections on the under side of the table D, in order to prevent backward movement of the latter after being moved forward by operating-pawl d. The said pawls d and d are both pivotally supported a little forward of their center, in order that their engaging ends or points may be held in a raised or elevated position for engagement with the teeth or projections d on the table D by the weight of their rear ends. When it is desired to move the table Dback to its normal startingpoint after being fed forward by the operating-pawl d, the rear ends of said pawls are elevated to lower their forward engaging points from engagement with the teeth or projections (l by a cam or eccentric d (more clearly shown in Fig. 3,) located beneath said rear ends of the pawls on a rod or shaft d, which is supported in suitable bearings beneath the table D. The rod or shaft cl projects at one end beyond the frame A, and is provided with a suitable knob or handle, by which the operator may operate said shaft and the cam or eccentric thereon, as will be readily understood.

E represents a device for adjusting the feed or forward movement of the table D by its operating-pawl d, and it consists, as more clearly shown in Fig. 4, of a plate pivotally supported on the frame or stand A adjacent to the opening therein through which the pawls d and (1 project and provided with an arm or extension 6, forming an apron, which projects over the said operating-pawl d with its forward end adjacent to the engaging end or point of said pawl. The front edge of the apron e is adapted to be adjusted in its relative position to the engaging end or point of the pawl cl, in order that the said pawl may engage with the teeth or projections (Z on the table D sooner or later by with the pawl-carrying frame 0 shifting or adjusting an arm or extension 6 thereof. The latter is adjusted and secured in its adjusted position by a set screw or pin 6 the stand or frame A being provided with a series of openings (L for the reception of set screw or pin 6 It will be readily understood that apron e, projecting over the pawl d, as described, will prevent the engaging end or point of the latter from engaging the teeth or projections d on the table D until said end or point has passed beyond its edge, and by moving or adjusting its position the end of the operating-pawl will be released sooner or later to engage the teeth or projections 01 and thereby adjust the feed of the table, as will be readily understood by those skilled in the art.

The operation of my improved machine, in brief, is as follows: The boolccover and the sections to be secured thereto are clamped in a fixed position on thetable D by suitable clamping devices H H, and the adjusting device E is regulated to adjust the movement or feed of the table D, according to the amount of space desired between each section. The foot-lever d is then depressed, thereby lowering the forward end of the hinged frame B (through the medium of the connecting-rods d and G and the arm or segment d) and causing the end or the plate 0 to engage or contactwith the book-section I and the staple-driver c at the continued downward movementof its supporting-frame to engage the staple retained in the guidewayc by the retainingspring 0 and push it past the latter and drive its ends through the sectionand cover and clinch the same, as will be readily un derstood by those skilled in the art. At the continued downward movement of the frame B to operate the staple-driver after the plate 0 is stationary by reason of its contact with the book the forward end I) of said frame B engages and depresses the forward end of the hinged frame 0 and causes the end of the pawl 0, carried thereby, to withdraw into engagement with the next preceding tooth or projection on the feeding roll or device 0 and as the foot-lever d is released by the foot of the operator the forward end of the frame 13 and the devices supported thereby are elevated by means of the counterbalance-weights d and the frame B is raised from contact The latter is then moved or elevated to its normal position by its operating-spring and causes its pawl 0 to move or operate the feeding-roll c to release a staple, which latter slides into its receiving-guideway 0 in position to be operated on by the staple-driver 0 at the next depression of the latter. The book-supportd and. move the pawl 01, supported thereby, back into engagement with the next preceding tooth or projection on the under side of the tableD, and as the'said hinged frame 13 is elevated by thecounterbalance-weight d the cam or eccentric d is operated in the opposite direction and causes the said operatingpawl d, through the medium of its supporting and operating lever, to move or feed the table D forward and bring the book secured thereon in its proper relative position tothe staple-driver to have the next succeeding section secured to the cover. In order to allow the table D to be moved back to its normal starting-point after the book secured thereon has been bound, the engaging ends of the pawls d and d are lowered from engagement with the teeth or projections cl on the under rangement of the several parts forming the, machine as set forth, as it is obvious that various changes might be madein the construction and arrangement of such parts without departing from the spirit of my invention.

It will also be understood that the number of the staple feeding and driving devices used in connection with the machine maybe varied in accordance with the number of staples desired to be used in securing each section to the cover. trated in Fig. 1, four of such feeding and driving devices are shown in position on the machine.
