.To all whom, t may concern:

Be it known that I, -LoUIs JOSEPH ANTON STANIEWICZ, bookbinder, of thel city of Chat# ham, in the county of Kent, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Bookbi'nders Clamps, as hereinafter more particularly explained. l

My invention relates to improvements in adjustable clamps or clamp-stands for holding books during embossing and gilding, 85e.; and the object of the invention is to devise a simple clamp-stand whereby a book maybe tilted or swung horizontallyinto a convenient position for the workman to emboss, gild, or otherwise decorate or work upon it; and it consists, essentially, of a stationary base arcshaped in cross-section, a rocking base also arc-shaped in cross-section vand designed to rockvupon the stationary base, such stationary base being designed to'be changed in position or swung horizontally and held station: ary while in use and the rocking base being provided with clamping-bars between which the bookis held,the clamping-bars and clamps being suitably secured to the top of the rocking base and such rocking base being provided with a central spring connection to the floor and the parts being otherwise arranged and constructed in accordance with my invention. p

Figure l isa perspective view of my clamping-stand, showing it placed on a table and exemplifying the applicability of my invention. Fig.,2 is a cross-section. detail of the base-board. yFiga isan inverted detail of the stationary baseor base normally held stationary. Fig. 5v is a detail of" the rocking base. Fig. 6 isa detail of the ball-bearing through which the flexible cord extends which connects the rocking base toV the stationary base. Fig. 7 is a detail of the tension-spring for the flexible cord and the device for varying the tension of the same.

In the drawings like letters of reference indicate corresponding parts in each gnrel..

Al isa table of any ordinary construction, upon which my device is placed. i B is the base, which is provided with a central ring b, held in a circular opening in the same and in the center of which is a hole b.

C is the base, which is ordinarily held sta-I Fig. 3 is ai Yplaced uppermost.

hole b2 in the base B into a hole c in the base.

The plunger D is provided with an annular projection d, between which and the enlarged hole through which the plunger extends fits the spiral. spring d in order to hold the plunger in the hole c in thebase C.

It will be noticed that the stationary base O is arc-shaped in cross-section and provided with end grooves c?, provided lwith rubber strips, as indicated.

E is the rocking base, which is provided with a central hole e, a cross dovetail-shaped groove e', in the center of which is located the ball-bearing e2, comprising the rings e3 and `e4 and balls e5 and beads e, provided with suitable rubberstrips e7, designed to enter the corresponding grooves in the stationary base C.

F is a cord which extends through the holes e, being suitably knotted at the top above the ball-bearing e2, the holes c and b to the spiral spring G, which is connected at the top to the triangle g, as indicated.

g is a bracket provided with a depending hook g2, and g3 is a thumb-screw which extends through the upper `member of the bracket and the basepof the triangle.

By means of the thumb-screw g3 the tension of the spring G maybe varied-that is -to say, the tightness by which the rocking base E is held upon the stationary base O may also consequently be varied. n

H H are clamping-bars, between which the book I Vis held, the back of the book being The bars H and H are provided with tongues 7L and h', which fit into the groove e' and are designed to have longitudinal movement therein. J isa clamping-screw which extends through Vthe bars H and Hl and the tongue 7L against the base' of the groove e', this clamping-screw being designed to hold the clamping-bars in position when placed centrally crosswise of the rocking base E.

K represents ordinary clamping-screws, which extend through the end pieces k2, at-

tached to or forming part of the clampingbars H.

IOO

By loosening the clamping-screws the book may be removed. Such screws are preferably provided with right and left hand threads meeting at the center, so that by turning the screws the bars move apart in order that the book may be quickly released.

Having now described the principal parts involvedin my invention, Ihave briefly to state and it will be readily seen that the book may be tilted over laterally into a position convenient for the workman, so that he can emboss and burnish without any strain and with a perfect rest for himself upon the book or part of the frame. work requires release the plunger D and turn the whole device around horizontally to any desired position and work on it in that position either at right angles or otherwise to the position shown in the drawings.

The spring G and cord F, it will be readily seen, allow of the base E to rock upon the base C with facility, and yet connect them securely together. Should it be desired to hold the bases G and E stationary, I provide end bolts or pins L, which fit into brackets Zand Z. on the bases C and E, respectively. The bolts or pins L are of course withdrawn should it be desired to allow the bases to rock one upon the other, so as to tilt the book into any convenient position desired.

That I claim as my invention isl. The combination with the stationary base provided with a curved or arc-shaped top, of the rocking base provided with a curved or are-shaped bottom designed to rest upon the arc-shaped top, the clamping-bars secured on the rocking base and designed to receive between them the book to be embossed, means for holding such bars together to grip the book and means for connecting the bases together, so as to permit of a rocking lateral movement as and for the purpose specified.
