I To (ZZZ whom. it nceM.--.

Be it, known that'I, Cumin-n Ffl-McBnn,

-' alicitizen .of the :United States-,-="residin' at f Athens, in.;.thef -county of :Athens' and tate of Ohio, li-ave inventedF9, certain new and useful 'Improveu'ient in Back Measurmgand Shaping -Devices for Bookbinding Ma'- "chines, of-whi ch the fpllowing is a specifica- My invention. relatesjto binding machines adapted to form volumes in. which a metal back-is employed, and has for its object'to of the same;

, provide-an attachment therefor which. will measure and-shape the back to fit the size of .-'the articular volumeunder construction.

y, -jinvention consists of certain details pointed out in my claims and illhstrated in the accompanying drawings, in which Figure 1 shows a front elevation view of a, binding machine, with my attachment thereon;

Figure '2 shows a vertical sectional view Figure 3 shows a detail view of a part of my device, a portion of same being broken away to reveal working parts; Figure 4 shows a detail view, in section, taken on the line 4-4, in Figure 3-;

Figures 5 and 6 show detail views, in section of the shaping means, I employ;

.Figure 7 shows a detail view, in section, of the measuring means, I employ;

Figure 8 shows a detail view of a back which has been measured and sized, and ready to be shaped; and

Figure 9 shows a perspective view of the back. properly shaped and ready for use in ,forming the volume.

Referring to the accompanying drawings the reference numeral 10 is-used to indicate the upright standards of a binding machine, in which a pressure bar 11, is designed to operate. Secured to, and extending rearwardly from, the standards on each side of the-machine, is a supporting frame 12, said tween the said depending portion and plate 16. The plate 17 is mounted by bolts 19 secured in-the depending portion and plate 16, which bolts are placed in ver-' tical oblong orificeslS in the plate 17. Each outer end of the plate 17 rests upon an angled slidable bar 20 mounted, as shown, to slideinwardly and outwardly. The upper end of the plate 16 is on a line with the upper edge surface of the bar 14, and also in line with the lower surface of the rotating shaping lever 13, when it is resting in normal position, as shown in Figure 2. Each of these angled bars 20 is secured to a rod '21 along which it slides when being moved to its proper position. A handle 22 is secured to each angled bar 20 and handles 23 are secured to the shapinglever 13. Secured to, and extending upwardly from,

means of each sideof the pressure bar 11, is a meas- .uring plate 24, its upper surface being angled, as shown, and the upper, and inner point thereof being above the horizontal line of the lower. surface of the bars 21. It is obvious that as the pressure bar moves it .carries with it the measuring plates 24,

thus elevating and lowering them. As. the volume to be built must be held in position during the operation by the pressure bar it is obvious that the thickness of the volume will determine the exactposition of the measuring plates.

In practical operation a stock size of back 27 is employed for all volumes up to a certain given thickness. When the pressure bar is in position to perform-its function the measuring plates, as before stated, are in a certain definite position. The sliding angle bars 20 are then pushed inwardly until their lower corners contact the angled surface of the measuring plates, the bars obviously controlling the position ofthe plate 17. The shaplng of these bars 20 is carefully determined from exact measureinents, so that the angle of the bar on the surface extending outwardly from its apex will function properly, as hereinafter set forth. As the pressure bar 11 is set against the papers and covers-to form the volume the plates 24 aredefinitely positioned. The

angled upper ends of these plates 24 are designed to form stops for their respective frames 12. It is obvious that as the upper surface of the bars 20 are angled and as these angled ends contact the under surface ticular volume under construction.

of the movable plate 17, the relative position of the late 17 within its supporting plates 15 and 16 will be determined by the position of the plates 24. Thus, if the volume under construction is narrow the movable plate 17 will be in a lower position within its supporting plates, than if the volume under construction were thicker. This relative arrangement of parts (the angle of the bevel on the plates 24 and their positionin'g, and the angle and positioning of the bars 20) is considered in the construction of the machine, so that in the volumes under construction the upper edge of the plate 17 will be in the right position, so that by inserting the end of one of these stock metal backs 27 in the space between the plates 15 and 16 until the end of the metal back contacts the upper end of the plate 17, the shaping lever 13 may be operated and the metal turned back upon itself. The opposite edge of the stock metal back is then inserted in the same way and bent back upon itself, and these bent back portions constitute the metal in the stock back which is not necessary or desirable for use in forming the par- In other words, this metal may be considered as excess metal and my arrangement provides for disposing of the same. In the drawing, Figure 5 illustrates how the metal back is placed as hereinbefore described and how the shaping lever operates to turn it under,

' and Figure 6, illustrates how I then take the metal back out of the space between plates 15 and 16,. place it on the outer surface of the plate 16 and force the shaping lever down upon it, so as to bend the metal completely upon itself.

The angled bars are then pulled out wardly (obviously moving the plate 17) to their limit of movement, which ismechanically. determined by the lugs 25 engaging the lugs 26, as shown in Figure 4. The angle of the bars 20, inward from the apex thereof, is predetermined sothat when the bars are at their outwardlim'it of movement the plate 17 will be in a'proper relative position that when the measured back 27 is inserted between the plate 16 and the bar 14 and the shaping lever rotated, as

illustrated in the dotted lines in Figure 7, the desired fian' e will be turned at a right angle. The other edge of the measured back 27 is then treated in the same manner, and a U shaped back of an exact size to fit the volume under construction is formed, as shown in Figure 9.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is:

1. In a book binding machine having a pressure bar to retain the sheets in position, an attachment for measuring and shaping the back to be used in forming the volume, comprising a carrying frame with a movable plate; means for positioning the movable plate to measure the flanges to be formed on the back, and means to form the said flanges, substantially as shown and described.

2. In a book binding machine wherein stock sized metal backs are used in forming the volume, a measuring and shaping device comprising a stationary portion and a movable plate mounted therein; a shaping lever rotatably mounted; a pressure bar; means connected with the pressure bar and the movable plate for positioning the plate by the movement of the pressure bar, substantially as shown and described.

In a book binding machine in which stock sizes of metal backs are used in forming volumes of varying thickness, a pressure bar; a movable plate; means connected with the pressure bar and the movable plate for positioning the movable plate in proportion to the movement of the pressure bar, the construction being such that the positioning of the plate by the movement of the pressure bar will determine the distance a metal back may be thrust intothe measur ing and shaping device, substantially as shown and described.

4. In a book binding machine in which stock sizes of metal backs are used in forming volumes of varyin'g thickness, a measuring and shaping device provided with a slot to receive the edges of the metal backs for shapingya plate movably mounted in said'slot; means connecting the pressure bar of the binding machine and the'movable plate wherebythe movement of the pressure bar determines the position of the plate in the slot a shaping lever-rotata-bly mounted, substantially as shown'and described.

foregoing specification.
