BOOKBINDER S CASE GAUGE INVENTOR Patented Nov. 19, 1935 PATENT OFFICE BOOKBINDER S CASE GAUGE Walter John William Wilson, Victoria, British Columbia, Canadal Application January 8, 1934, Serial No. 705,832 In Canada April 8, 1933 10 Claims.

. art which has hitherto, to a very larger extent, partaken of the nature of one of the strict hand-` crafts, has naturally been confronted with corresponding difficulties when mass production of books has been called for, and an object of this invention has been to greatly increase the rapidity of afxing and securing cases (or book covers) and also with much greater precision and exn actitude than has hitherto been practicable with the slower hand processes.

The invention resides in the novel combination and arrangement of parts, as fully described herein with the aid of the drawing which accompanies and forms a part of this application, and in which Fig. 1 is a plan view of the device,

Fig. 2 is a longitudinal elevation on line 2.-.2 of Fig. 1 and Fig. 3 a cross sectional elevation on line 3 3 of Fig. 1.

The drawing indicates one preferred embodiment of the invention, but is not intended to be limitative as regards precise details of construction except as such may fall within the language and the scope of the claims.

It will be observed that the device is in table form, the top surface plate or table proper being divided transversely into two portions so as to leave a rectangular recess between'them for the reception of the back strips.

The width of this recess is made adjustable by longitudinal movement of one half of the table top. This back strip recess is also adjustable,longitudinally and is provided with a suitable vertical feed device for the lproper presentation of the strips.

A variety of other adjustments and devices in connection with the reception and manipulation of the boards, cloth, and other elements concerned are arranged adjacent the table surface and are more specifically referred toas the description workof a. rectangular table which maybe constructed in any convenient manner as with verticaliangle-.irons to for-m the corner uprights, secured in any convenient and usual manner to make .,a. rigid support. for the horizontal table plates l and 8, the former being the xed portion thereof. The adjustable portion 8 of the rectangular table is securely held in any desired position by transverse bolt 41 and wing nut 48 which operating through the framework 3 causes the latter to securely grip strips or projections 49 aixed to the under side of the adjustable table plate. Slidable transversely over the top surface 5 of the table plates 'l and 8 is the rectangular cross-sectional fiat guide bar 9 against which the top edge of the boo-k boards are abutted. This guide bar is actuated and adjusted by the revolvable screw I0 which engages the nut H 10 traversing the screw I0 and the longitudinal guide slot l2 in the top of the table l.

The additional guide slots I3 which are engaged by corresponding projections on the lower side of the guide bar 9 provide the necessary l5.

restraining action to the latter and insure its parallel movement.

Removable clamping gauges I4 provide a ready means for adjusting the top gauge I5'and are secured to each half of the table top l and 8 20 by clamp screw I6. On the outer portion of each half of the table top are side gauges Il which are traversed longitudinally in the parallel slots I8 and actuated therein by the screw and nut device below them which is adjustable by the 25 milled hand-wheels 20. Joint gauges for positioning the back boards in relation to the back strips are provided at 2 I. The stops which constitute the joint gauges are slidable in the short slots `22 and actuated longitudinally therein by 30 nut and screw device below them, the screw member thereof 23 being actuated by revolution of the small milled hand-wheel 24 within lthe slot 25 and immediately below the surface of the table top land 8.

The back strip recess 26 is a salient feature of the device. 'I'he walls 2l of this recess ar-e each secured to their respective portions of the table tops 'l and 8 and between them is a vertically slidable table construction 28 supported by 40 the telescopic support 29 the lower tubular member of which is secured to and supported by the flat plate member 30.

Slightly above the plate 3B is a similar plate 3|, between this member and the table 28 and at 45 each -end thereof are vertical springs 32 which afford the slight upward thrust required for automatically feeding the back strips upwardly as they aremade use of. This lifting effect is further regulated or adjusted by a hand lever 33 50 which is fulorumed at 43 and at its opposite end projects conveniently beyond the end of the table framework, and is .adapted to engage a ratchet bar 34. This lever..33"which is .conveniently Ormed of a flat bar is twisted at its centre 35 6 5 so that its flat surfaces are horizontal where they connect to the spring supporting plate 3 lV through a springend bolt attachment 36.

A backV strip longitudinal adjustment is provided at 31 andV consists of a bracket 38 secured to the' framework 6 and carrying a movable plate 3S secured to the screw mand the pin guides :il horizontally movable in the bracketY 38. The screw k40 is reciprocated by the restrained hand nut 42 which its thread engages.

A further longitudinal adjustment to the back strip is provided at'the opposite end thereof and consists of a short flat plate I3 having an abrupt downturned end and positioned and slidable against the underside of the flat gauge plate 9,

each of the plates'43 and 9 having alongitudinal Y' slot Mand'i respectively and the two slots being right angularly disposed to each other and secured in any desired relation by the screw boltV 56, so that in addition to the longitudinal adjustment there is a transverse adjustment whereby a very narrowY back strip may be promptly allowed for. By these two independent longitudinal adjustments a gauge-stop is provided at each end of the back. strip.

In operation the case gauge is adjusted and Set in all its particulars to conform with the speciiications of the required cases, and in further preparation a sufficient quantity of back strips are then placed in the back strip recessV 2G and on the carriage 28.

Two boards are then placed flat on the table 'l and 8 with their edges respectively tting loe- Y tween and abutting on the ilat guide bar s, side horizontal table, said table being divided trans-VV versely into two portions, one being slidable from or towards the other and adjustable in any desired position whereby a relatively narrow rectangular recess is provided between the two said portions of the table top, said recess being adapted to receive back strips.
