SPECIFICATION forming` part of Letters Patent No. 569,685, dated October 20, 1896.
ppiication filed 111155.19, 1895. Renewed September 9, 1896. Serial No. 605,331. (No model-l T all whom t #my concern.-
Beit known that I, FRANKLIN D, TIFF, of Beaver Falls, in the county of Lewis, in the State of New York, have invented new and useful Improvements in Apparatus for Shaping lVood and Pulp Plates, of which the following, taken in connection with the accompanying drawings, is afull, clear, and exact description.
Ic This invention relates to the class of apparatus which are provided with a steamheated cylinder containing the dies between which are placed the blanks to be pressed into shape by the power of a screw applied to the die in one end of the cylinder.
The invention consists in an improved construction and combination of parts constituting an apparatus which is simple and comparatively inexpensive in construction and 2c most convenient and etlicient in its operation.
In the annexed drawings, Figure lis partly a top plan view and partly a longitudinal section of an apparatus embodying my invention. Fig. 2 is a front end View of the same.
Fig. 3 is a vertical transverse section on line X X in Fig. l, viewed toward the adjacent end of the cylinder; and Fig. 4 is a detached perspective view of the rack which supports the blanks in the cylinder, portions being 3o broken away to illustrate the detail construction of said rack.
Similar letters of reference indicate correspending parts.
O represents the metallic cylinder in which the blanks are to be treated. This cylinder is formed with a steam-jacket D to heat the blanks during the process of pressing them into shape. The steam is admitted into said jacket by a steam pipe or pipes a, connected 4o to one end thereoiand a drip-pipe (not shown) is connected to the base of the opposite end of the jacket for the escape of the water of condensation. The jacket D is of segmental shape in cross-section to form in the upper portion of the cylinder the openingD',through which to introduce the blanks into the cylinder and remove them therefrom after the blanks have been pressed into the requisite dish shape.
5o A suitable door B, hinged to the jacket, as
at b, orotherwise removably connected thereto, closes the opening D' during the process of shaping the blanks. R denotes a rack which is employed for supporting the blanks within the cylinder. The aforesaid opening 5 5 D' is of sufficient size to allow said rack to pass sidewise throughit. In order to effectually expose the blanks to the heat in the cyl in der O, I make said rack of the form of a skeleton frame, consisting of cradles c c, of ap- 6o proximately semicircular shape and formed with eyes d d d, through which pass rods d', provided with nuts on their ends. The cra dles are confined at their requisite distances apart by means of metallic pipes, preferably sections ff of pipe abutting against the cradles and receiving the aforesaid rods through them. To brace and properly sustain said cradles in the cylinder, I form the cradles with feet c c, by which they rest on the inte- 7o rior of the cylinder, as shown in Fi g. 3 of the drawings. Y
g and g represent, respectively, male and female dies for shaping the blanks placed between them, as illustrated in Fig. l of the drawings. One of the dies, preferably the female die g', is seated in a recess a" in the inner face of the adjacent head h' of the cyl inder and is retained therein by a bolt u, passing through the head and entering a screw- So threaded socket in the back of the die. The other die, g, is formed with a hub j in the cen ter of its outer face, and this hub is formed with a socket in which the end of the pressscrew I is pivotally secured by means of a 8 5 screw r, passing through the side of the hub and entering a circumferential groove in the screw.
The cylinder O rests horizontally on stout saddles S S,whicl1 are secured to cross-beams 9o F F, mounted on longitudinal sills G G. The two heads h and 7L of the cylinder O are tied to each other and to the cylinder by means of stout longitudinal rods i172, passing through and fastened bynuts t" and collars Htc cross- 9 5 bars L L, extending across the sections of the cylinder-heads h h. The tie-rods il i extend beyond the end of the cylinder through which the screw I protrudes, and to said extensions are fastened the two cross-heads N N, whichl are provided in their centers with openings through which the screw I passes. Between IOO beams F', fastened to the sills G G.
the said cross-heads is sustained the hub O of the gear-wheel O. Said hub has its axial orifice screwthreaded and constitutes the nut of the screw I, which passes through it. A shaft l, parallel with said screw, is mounted in suitable bearings Z Z', secured to cross- To this shaft are fastened a driving-pulley n and a pinion Rwhich latter meshes with the aforesaid gear-wheel O. A belt (not shown) connects the pulley n with a suitable motor and transmits rotary motion to the ,shaft Z. The engagement of the pinion P on said shaft with the gear-wheel O causes the latter to partake rotary motion. The hub of said wheel serving as a nut for the screw I causes the latter to travel longitudinally. By changing the direction of the motion of the drivingbelt the Screw is made to travel toward and from the cylinder C.
In an extensive apparatus having a cylinder C of considerable length I employ intermediate dies 't interposed at intervals between portions of the row of blanks, as illustrated in Fig. l of the drawings.
The operation of the designed apparatus is as follows: The screw I having been retracted to carry the die g to one end of the cylinder C, the door B is opened and the blanks of wood or pulp are introduced through the opening D' and placed contiguously side by side in a row and endwise into the rack R, and, if necessary, the intermediate dies t t are inserted at the same time. After the blanks and said dies have been properly adjusted the door B is closed and the steam turned on to charge the jacket D and thereby heat the cylinder C. The blanks in said cylinder are thereby rendered more elastic to yield to the subsequent shaping process without splitting. The screw I is then set in motion to compress the row of blanks between the dies and thereby impart the desired dish shape to the blanks. After the blanks have been held in said condition for a sufficient time to render the shape permanent the aforesaid operation is reversed. The efficiency of the steam-heated cylinder C is materially enhanced by the heads h 7i', closing the ends of the cylinder and confining the heat in the cylinder during the operation of shaping the blanks'.
Vhat I claim as my invention isconnected by rods d d and metallic pipes fj" receiving said rods through them and abutting against the cradles substantially as set forth and shown.
3. The combination, with the cylinder C,
die g and press-screw I, of the head it formed l with the recess r', the die g' seated in said recess and the bolt u securing said die to the aforesaid head as set forth and shown.
et. The combination of the cylinder C formed with the steam jacket D and opening D through said. jacket, the door B over said opening, the heads 7L 7i closing the ends of the cylinder, the rack R seated in the cylinder for supporting the blanks, the die g' fastened to one of said heads, the press-screw I extending through the opposite head, and the die g pivotally connected to said screw as set forth. f
5. The combination of the cylinder C formed with the steamdjacket D, the heads 7i 7L closing the ends of the cylinder the tie-rods z' 'L' se curing said heads tothe cylinder and extending beyond the head 71., the cross-heads N N secured to the extensions of said rods, the press screw I passing through said cross-heads, the nut O confined between the cross-heads and formed with the gear-wheel O, the shaft Z parallel with the said screw and provided with the driving-pulley n, the pinion P fixed to said shaft and meshing with the aforesaid gear-wheel, the die g connected to the inner end of the screw, and the die g seated in the opposite end of the cylinder substantially as set forth and shown.
In testimony whereof I have hereunto signed my name this 19th day of March, 1895.
