G. STABER. WOOD EMBOSSING MACHINE.
No. 518,902. Patented Apr. 24, 1894'.
UNIT D ST TES PATENT O E.
GEORGE STABER, OF BROOKLYN, NEW YORK.-
WOOD-EMBOSSING MACHINE.
SPECIFICATION forming part of Lettelrsfatent No. 518,902, dated April 24, 1894. Application filed December 17, 189;. I Serial no. 455,521. (lloinodeln This invention relates to a machine for em bossing or charring wood, and other sub stances for the purpose of ornamenting the surface thereof, and is designed more particularly as an improvement on such machines as shown and described in the Letters Patent granted to me under date of May 12, 1891, No. 451,983.
The prime object of theinvention is to simplify the construction and consequent operation of the same by first providing a cheap and effective means for regulating the tension of the pressure spring and preventing said spring from extending its force, by the parts becoming loose from wear or otherwise, and secondly by bringing the means forpositively moving the pressure roll to and from the design roller, into such a position that an attendant may manipulate the same, without the objectionable necessity of stooping and going beneath the machine.
Other objects and advantages will appear from the following description and claim when taken in connection with the annexed drawings, in which- Figure 1, is a front elevation of a wood embossing machine, embodying my invention, and Fig. 2, is a detail side elevation of the same.
Referring by letter to said drawings: A, indicates the main frame, which comprises the fixed base a, and the uprights or standards I), 6, arranged in two pairs, one pair being on each side of the machine. These standards b, b, are provided adjacent to their upper ends with suitable bearings for the trunnions (l, of the design or die roller B, which may be rotated through the medium of any suitable gearing. Mounted between the standards b", b, of the main frame A, are the vertically disposed end bars e, of the approximately yoke shaped and vertically movable frame 0,
in which end bars are journaled the trunnionsof the pressure roll D.
In the center of the bridge or cross bar f, of the adjustable frame 0, I provide a vertical aperture (not illustrated), through which passes the upper end of the vertical lifting rod or bar E,'arranged in about the vertical center of the machine. This lifting rod or bar E, the upper portion of which is screw threaded as shown, takes loosely through the hole in the frame 0, and the lower end of the rod or bar is passed through a hole in the base of the frame through which it is adapted to move vertically, the rod having-a groove as shown, into which takes a spline fixed in the hole of the base, whereby the said rod may be prevented from turning as ascrew.
For adjusting the pressure roll D, with respect to the design roller, I have shown mechanism similar to that disclosed in my application filed May 17, 1892, Serial No. 433,326. This mechanism comprises the horizontally disposed beveled gear wheel F, which is provided with a central vertical, screwthreaded aperture for the passage of the lift ing rod E, and the shaft h, which is journaled in' the end bar of the frame 0, and is provided with the hand wheel 11, and the beveled pinion g, through the medium of which the gear wheel F, is rotated to raise or lower the frame and consequently the pressure roll.
By this construction it will be readily perceived'that a person standing at the side of the machine may quickly and conveniently vary the height of the frame 0, and the pressure roll D, by turning the hand wheel f, in the desired direction to lower said frame to permit of the interposition of stock, or raise the same so as to clamp the stock between the pressure and die rolls.
M, indicates a nut which isprovided with a central screw-threaded aperture t', to receive the lifting rod E, and is designed to be rotated to increase-and diminish the tension of the spring H, which surrounds the bar or rod E, and bears at one end against the fixed base a, of the main frame, and at its opposite end against the nut M. This not M, is cupped or provided on its under side with a preferably integral depending flange m, which surrounds the upper end of the spring H, and serves to prevent spreading of said spring when the same is compressed. The nut M, may be turned to regulate the tension of the spring, by a wrench or the like; said nut being lowered on the rod E, if it is desired to compress the spring and increase the tension,or raised when it is desired to expand the spring and reduce the pressure of the roller D, against the stock.
In order to prevent a casual rotation and upward movement of the nut M, and a consequent expansion of the spring H, incidental to the shaking and jar of the machine in operation, I provide the check nut I, which is mounted on the threaded rod E, above the nut M, and is designed to be turned down upon said nut when the same is properly adjusted. This check nut I, will effectually prevent any casual movement of the nut M, but it will not interfere materially with the adjustment of said nut inasmuch as it may be readily turned away from the same when the tension of the spring is to be regulated. By the provision of the checlrnut I, it will be seen that the nut M, will be securely held in its adjusted position and the necessity of the operator frequently getting under the machine to screw said nut down and compress the spring, is obviated, which is an important desideratum, inasmuch as any slipping or givthreaded rod bearing in the main frame, the
spring surrounding the threaded rod and bearing at one end against the main frame,a nut mounted on the threaded rod above the spring, and a check nut also mounted on the threaded rod above said nut; of a gear wheel having the central, vertical threaded aperture for the passage of the threaded rod and adapted to support the movable frame, and a V shaft journaled inthe movable frame and carrying a pinion at its inner end in mesh with the gear wheel, and a hand wheel at its outer end, all substantially as and for the purpose set forth.
In testimony whereof I affix m y signature in presence of two witnesses.
GEORGE STABER.
