Description
B. P. LEWIS Aug. 22, 1933.
DUPLICATOR Filed' Oct. 5, 1952 Inventor L/lllorney Patented Aug. 22, 1933 UNITED STATES PATENT. OFFICE DUPLICATOR .Benjamin Parker'Lewis, Rolla, Mo.
Application October 5, 1932. Serial No. 636,416 `1 Claim. (C1. 10i-'131) manufacture, strong and durable, easy to manip-V ulate, thoroughly eiicient and reliable in use and otherwise well adapted to the purpose for which it is designed. i
10 With the above and numerous other objects in view as will appear as the description proceeds,
the invention consists in certain novel features of construction, and in the combination and arrangement of parts as will-be hereinafter more 15 fully described and claimed.
In the drawings:
Figure 1 is a top plan view of the duplicator.
Figure 2 is an end elevation thereof;
Figure 3 is a side elevation thereof.
Figure 4 is a vertical longitudinal section taken substantially on the line 4-4 of Figure 1, and
Figure 5 is a perspective view of one ofthe sides.
Referring to the drawings in detail it will be seen that numerals 5 denote a pair of spaced parallel coextensive side boards connected at their central portions by across bar 6. Numerals 8 denote a pair of shafts journalled through openings adjacent the ends of the side boards 5 and these shafts extend outwardly beyond one of the side boards as is clearly indicated in Figures 1 and 2. On said one side board 5 there is fixed a clamping board 9 having longitudinally extending slits or slots 10 starting at the ends thereof and terminating equidistant from the center thereof. The board is also provided with openings 11 at intermediate portions ofthe slots. VThe shafts 8 extend through these openings. Bolts 12 extend through openings 14 and have wing nuts 15 on the upper ends thereof which may be manipulated to clamp the board 9 on the shafts 8 to prevent rotation thereof. Numeral 17 denotes a bed or work board mounted across the intermediate central portions of the side boards 5 and having edges beveled so that the gelatin strip 13 on the shaft 8 may be extended thereover and by proper manipulation of the shafts 8 and the splitclamp board 9 the gelatin strip may be properly tensioned.
It is thought that the construction, operation, utility and advantages of this invention will now be quite apparent without a more detailed description thereof.
The present embodiment of the invention has been described in considerable detail merely for the purposes of exempliication since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.
It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described my invention, what I claim as new is:
In a duplicator including a fram-e and shafts journaled therein and each having one end projecting beyondva side of the frame, a board fastened to the outer face of said side of the frame and having a shaft receiving opening adjacent each end thereof, said openings receiving the projecting ends of. the shafts, said board having longitudinally extending slits therein intersecting the openings, each slit extending from an end of the board toa point adjacent the transverse center thereof, a boltrpassing transversely through each end portion of the board and passing through a slit between an opening andan end of the board and a nut on each bolt, whereby when the nuts are tightened, the bolts will clamp the' slit portions of the board on the shafts.
BENJAMIN PARKER LEWIS.
