Application filed .Tune 10, 1924. .Ser'iaI No. 719,226.

The invention involved lherein relates toA the manufacture of bo'ok covers or other binders or articles of like character.

down to form a neat finish.

A characteristic example. is a book cover in which the covers or back or both are rein-r forced by stiff cardboard over which is drawn the outside finishing material such as leather7 fabric or paper. Y y

1n the finer grades of such book covers it is frequently desired `to have round corners;`

Such corners have given a. great deal of difficulty in the covering process and havev involved additional steps and additional eX- pense and frequently imperfect work.

My present invention contemplates mechanism by which such covers can be formed in a single operation with great rapidity and great accuracy. As illustrative of my invention I will show in the accompanying drawings an embodiment which I have 'found highly successful inpractical use.

Throughout the specification and drawings like`reference characters are employed to indicate corresponding parts, and in the drawings Figs. 1 and 2 are side and front elevations, respectively, of a press in accordance with my invention.

Figs. 3 and t are end and side elevations of the forming members in separated relation.

Fig. 5 is a plan view of the lower member.

Fig. ,6 a similar view with its rtop plate removed to expose the folding blades.`

Figs. 7 and 8 are sectional views showing the raised rand lowered positions of the suction plate.

Fig. 9 is a somewhat similar section showing blades projected and the press block down.

Fig. 10 is a view similar to Fig. 7 but showing the work'as it is released.

Fig. 11 is a fragmentary section showing the, adjusting blocks for the `suction plate.

Figs. 12 and 13 show in plan the positionings of the corner blades.

Fig. 14 is a side elevation, and

Such articles usually comprise a body portionbrl portions of thicker or stiffer vstock to which a sheet ofh covering material is attached,lthe same being drawn over the edges and folded y It 1s driven by the main shaft' and pulleyj 6. A usual hand control y7is provided andy Fig. 15l a section through a corner blade, and i Figs. 16 and 17 are plan views of the rtwo' leaves of the corner blades. f

REGINALD ALVIN MCCAULEY, OF DORCHESTER, MASSACHUSETTS, 4ASSIGNOR T0.

Referring to F igs.y 1 and 2, I have-indicated at l the base, at 2 the head7 and at 3 the reciprocating slide working in va way'li.l

Va foot pedal 8. A suction device 9 is conmember generally indicatedl as 11 consists of al plate 111 havinga Vseriesof bladeoperating lingers 112 which are for `the side blades and 113 which are the corner operating'iinl. gers. All these lingers are lwedge shapedfas at'llQl or 1131,-the`se wedging faces'aetingq being an oblong' body or sheet 'withround'ed corners as above suggested. Referring to Fig. 5, it will be seen that the top .plate la ofthe base is a rectangu-A lar "or quadrilateral piece having a central raperture of the size and shape of the partieularblank tobeoperated'on. The platesla .are removableand replaceable vto accommo-v date Vcovers of dilferent siZes'or shapes and act as a gage in locating the blank in' the machine. The lower member 121s a'bloek-shown in Fig. G as exposed bythe removal of the upper gage plate 14. It is recessed to a size'V preferably conforming tothe area and shape of the blank tov be yoperated on and foi` thatv purpose receives a suctionplate 15. provided with'a hollow-stein 16 by which it is operated and througl'i which 'it Iis vented.' The stem 16 is operably connected to a yoke 17 which by links 18 can be raised or lowered by rthe vpedal 8.

The initial operation is illustrated 'in the sections shown in Figs. 7 and 8,'the assembled blanks 'B and S glued or cemented together being positioned on the plate y111 over the suction plate 15. The exhaust valve is then opened and the blanks B and S are drawn to and firmly held by the perforated plate 15.

The foot lever 8 is then depressed and the plate lowered drawing the blanks B and S down so that the edges of the blank B are laterally upturned as shown in Fig. 8, being turned up against the edges of the stiffening material VS.

At this point the hand lever 7 is thrown and the press begins to turn over lowering the plate 11. The lingers 112 and 113 now Y` entertheir respective openings and engage the lateral blades 18 and corner blades 19 to, effect the edge turning motion. These blades'are provided with rollers laand 19- tive movement, the slide 19 being slotted to .receive a pin 19b between kwhich and the Wall of the slot is connected a spring 19C. This permits the slide 19 to move forward Vover the edge of the stiftening blank S as it turns the edge of the covering blank B over said stiening blank. Similar-bearing rolls 18b are provided in the lateral blades :tor 'contact with their operating lingers 112.

In initial positionfas shown in Fig. e, the combined blanks B and S are slipped `in while the plunger is raised so as to occupy the aperture of the gage plate 14 so as to be properly positioned. In this position it will be noted .that the edges ofthe blanks B which are gaged on the. inner edges of this .aperture overlie the slides 18 while the main body of the blank rests Von the suction plate 15. At this point the valve 10 is turned to its exhausting position and the plate 15 eX- hausted through its stem 10 thus drawing .the combined blanks firmly to its upper surface. The treadle is now depressed lowering the plate 15 to just below the level of the lateral blades 18. This turns up the margin of the blank B vertically so that it stands against the blades 18 with the main body of the blank just below the lower edge of these blades. This position may be accurately adjusted by the wedges 2O which are advanced or retracted by knnrled head screws 21 as appears in Figs. 9 and 11.

tion shown in Fig. 6. The corner blades 19 are timed toadvance just after the blades 18 come forward and draw up the material of the sheet B at the corner.Y The blades 19 and 191 advance together, the blade 191 being stopped by the resistance of the 'stiiffen-` ing blank `B and blade' 19 continues't'o ad vance aA distance represented by the turn. over of the leather 'orf other material being turned. Vxhen the blades are all in their proper position, the plunger 11 has reached the bottom of its stroke and the platell1 which is the size of the finished blank presses firmly down on all these blades thus pinching the covering material' firmly over they edge of the blank. The plunger; head now re-- treats, the footV pedal is released to Vpermitv the rise of the suction plate 15 to the -posi-V v tion shown yin Fig. 10 which is its initial position. The airis reversed froniexhaust to pressure and the 'blank released (from the suction plate and removed so that the inachine is ready for the next blank.

When it is desired to change the style or' size of cover to be made the head o1'. the press is lowered bringing the plunger plate to its lower position and the two plates thenv release, one from its plunger andthe other from `the bed of the machine and are lifted out together The machine can be loperated very rapidly and by unskilledlabor sothat theexperienced book binder vcan be replaced by unskilled help while at the same time production is increased, and .more perfect work produced. y

Various modifications may be made in de- 1 tails of Vconstruction and operation all without departing from the 'spiritof my invention if within the limits of the appended claims. l
