y supporting the sections which: embodyVV this rest upon the platform 4. The lingers are fastened to a shaft 5 having a. rocker arm 6 that by a link 7 is connected with the end of a lever 8V which is oscillated at the correct time by the vertical reciprocation of a cam actuated rod 9. The platform upon which the sections rest is carried by vertical screw rods 10 that are provided with crank handles 11 so that the rods may be turned'and the height of the platform adjusted according to the width of the sections. The finger shaft and the connected parts are carried by the platform so the fingers will move up and down when the height of the platform is adjusted.
As the section carrying arm goes up the presser bar 12 moves forward to permit the arm and section to reach stitching position. The presser bar extends across the front of the machine and is attached to rack bars '13 movably supported by the frame. Engaging with the racks of these bars are pinion segments 14 fastened to a shaft 15 provided with a rocker arm 16 that is rocked at the correct time by the cam reciprocated rod 17.
vWhen the section has reached its highest position it is stitched to the preceding section and the carrying arm descends. As the arm goes down the presser bar is drawn back and forces the stitched sections rearwardly. A bar 18 swings back as the arm moves down and the presser bar moves back so as to push back the front section near the middle. This bar immediately swings forward as the presser bar forces the section rearward and the carrying arm descends. When the carrying arm goes down the hngers swing forward so as to get out from back of the section just stitched. These operations are repeated in sequence as the sections are carried up and stitched, and the mechanisms for performing them are old and well known, consequently are not described in more detail.
As the stitched together sections stand with their lower edges resting upon the platform (Figs. 1, 2) they must be held closely pressed together or they will droopA and slump down so as to strain the stitching if the threads do not break, andas the sections are thicker at the head edge than at the tail edge, owing to the folding of the sheets of which the sections are formed (Fig. 5) unless tightly pressed the sections will fan out,7 that is, widen out at the head edge and tend to stand obliquely across the platform instead of squarely, as indicated by dotted lines in Fig. 6. The back support, however, cannot be immovable 4and form a rigid wall to enable the necessary pressure to be exerted for compacting the sections, for it must yield as the sections are stitched to alford room for the` subsequent sections to be stitched.
To assist in retaining the tail edges of the sections, that is, the rough edges which are not folded and which form the bottom edge of the completed book, a knife blade 19 is secured to a block 2O that is adjustably fastened on the frame bar 21. This blade is adjusted so that it will cut slightly into the tail edges of the sections near the back folds (Figs. 2, 3, t) and thus aid in supporting these edges of the sections. The head or folded edges \of' the sections are thicker,` stiffer and Asmoother and consequently do not need to be thus supported.
In order that the'sections may receive from the presser'bar the required pressure to .keep them square, notwithstanding that 4they are thicker at the head edge than at the tail edge, and vto vprevent them from drooping as a* result ofy looseness, a back support isprovided that can be moved rear- Yward only when the require-d amount of pressure is applied squarely across its whole face. This support consists of a block 22 that has its underside fitted to an undercut guideway 23 which extends from front to back in the upper surface of the platform.
l This guideway is formed nearer the head vside of the platform than the tail side so that the block will be nearer the side of greatest pressure. 1n sockets in vertical hubs 24C on the bloekare plungers 25' that are forced downward by springs 2G, the tension of which is regulated by thumb screws 27 screwed into t-he ends of the hubs.
The* springs force the plungers down uponv the rails 28 which form the guideway with a pressure determined by the adjustment of the screws. A vertical groove 29 is formed in the front of the block 22 for receiving the back plate 8O of desired size. The block is fitted to the guideway so that pressure upon one side of the backl plate will not move it rearwardly,an :l the friction of the lplungers is made of such resistance that only-the required amount of pressure exerted squarely and uniformly across theback plate will move the block.
As a result of this construction the book sections'can be crowded together by the pressure of the presser bar'until thev space between the presser bar and the back plate is completely filled.l Unless the sections completely fill the space iand push back squarely and uniformly across the Vwhole face of the baekplate, the back plate will not yield. This allows the application of such a degree of pressure that the folded head edges of the book sections will be crushedv together and the tail edges compactly held so that the secti-ons will be supported firmly and squarely, and thus enable the other mechanisms of the machine to properly perform their functions andr the stitching to be of the desired regularity and uniformity.
The invention claimed is; 1. The combinationin a book stitching machine,of' a. platform for supporting on edge thestitched book sections, a guideway extending on said platform, from front to back near the head side, Va slide with a porf tion loosely Vfitted to and movablefback and Vforth along said guideway, a back plate carried bythe slide, and adjustable means carried by the slide and engaging opposite sides of the guideway for friotionally re sisting the movement of said slide and back plate along the guideway.
