PRESS FOR SHAPING PLATES FROM VENEERS.
SPECIFICATION forming part of Iletter Patent No. 506,417, dated October 10, 1893.
I Application filed May 6, 1893.
To all whom it may concern..-
Be it known that I, CHARLES W. COLONY,
of Sandy Creek, in the county of. Oswego, in
the State of New York, have invented new and useful Improvements in Presses for Shae ing Plates from Veneers, of which the followmg, taken in connection with the accompanying drawings, is a full, clear, and exact de- In the annexed drawings, Figure l isa rear.
elevation of a hot-press embodying my invention. Fig.2 is a vertical longitudinal section of the same. Fig. 3 is a vertical transverse section on liners, m, in Fig. 1. Fig. 4isafr0nt elevation showing the same in position for either introducing the blanks or removing the blanks from the press, and Figs. 5 and 6 are transverse sections on lines y,.'y, and 2, z, in Fig. 2.
Similar letters of reference indicate corre sponding parts.
AA represent the supporting frame of the press, between the end-walls or posts of which frame is supported the holder for the plates or analogous articles to be compressed and shaped. This holder may be of any suitable shape adapted for the aforesaid purpose. I preferably, however, divide said holder longitudinally or form it of two separate semicylindrical sections B and B- and in order to increase the efficiency of the apparatus I surround each of said sections with a jacket -C- heated either by steam, or by hot air, or by hot Water, preferably by steam. The aforesaid sections are arranged to form a horizontal cylinder and preferably with the joint between the sections in a horizontal plane. The lower section is secured stationary in its position, and the upper section is hinged at one of its longitudinal edges to allow it to be swung off from the lower section stun No. 473,216. (No model.)
so as to obtain access to the interior of the .lower section when required for either introducing the blanks or removing the plates or compressed articles. The upper section is supporteda sufficientdistance above the lower section to form longitudinal slots or guides Ia.a betweenthem when the holder is closed, in which condition it is held by means of suitable removable clamps -c c.
; D denotes a die which issustained stationary in one end of the holder, and F- is the follower in the opposite end of said holder. Said follower receives the compressing ower which may be either hydraulic or steam, or
sired.
' The power illustrated in theannexed drawings consists of the screw I- which is firmly secured to the follower and extends through the adjacent end of the holder and through the two posts -PP- to one of which is fastened a metal plate -bprovided with an aperture through which the screw -I passes, and with an annular groove surrounding said aperture. In said groove are placed a series of balls b on which bears the nut d which works the screw I. The end-bearing of said nut is thus relieved from friction. 1 p
.To the nut is fastened a wheel --cby which to turn said nut. For'this purpose I ing with a pinion e attached to a shaft fon which are two loosely mounted pulleys JJp between which is a suitable clutch-collar '-J'- fastened to the shaft.
with suitable means for engaging said clutchcollar by shifting the pulleys toward the same. The driving belt of one pulleyis straight and that of the other pulley is crossed and thus said pulleys revolve in opposite directions, and by shifting said pul: leys on the shaft so as to cause one of the pulleys at a time to engage the clutch collar the nut is rotated so as to cause it to force the screw in either direction as may be desired.
The follower -F is provided on opposite edges with lugs or projections -F' by which it slides in the guides or slots -aa and is thus prevented from turning.
compressed air, or screw-power as may be de-.
prefer to provide said wheel with cogs mesh- The adjacent faces of the pulleys are provided 7 Between the end-die -D- and follower F- are hollow dies ii which have projecting from their side edges hollow trunnions -t"i'- by which they ride on the guides aa and are thus free to move longitudinally in the holder. The end-die D- I also form hollow and provide it with the aforesaid hollow trunnion.
For heating the jackets -OC- and hollow dies I prefer to employ the main steampipe g which extends lengthwise of the holder -B-B' at the rear thereof and communicated with the interiors of the jackets by branch pipes or hose h-htapping the lower section -B at its bottom, and the upper section --B' at its rear edge, so that in throwing thelatter section into its open position the water of condensation will pass from said section down to the pipe g. The hollow dies communicate with the steam-pipe g by flexible pipes or hose h'- attached to nipples on the pipe --g and to the hollow irunnions -iz"- on the edges of the dies adjacent to the said steam-pipe. The trunnions on the opposite edges of the dies I prefer to provide with a vent for the escape of air in charging the dies with steam, said vent being provided with suitable removable stoppers or valves t". The flexible pipes or hose --h are of sufficient lengths to allow the dies to move freely longitudinally in the holder -BB- in the operation of the press, and in order to properly support said hose I attach to the trunnions -i suitable hangers -Z-Z which are loosely mounted on the rod j which extends lengthwise of the aforesaid holder at the rear thereof and is secured to the frame A. By means of the aforesaid hangers the dies z'-z' are hinged on the rod jso as to allow the dies to be swung up on t of the lower holder section -B-' and over into the upper Section 'B'- when in its open position. I also prefer to employ the rod j for hinging thereon the upper section --B-.
In operating the described press the upper holder section -B' is swung back into open position, and a tier of blanks is placed against the stationary die D. Then the nearest die -i is placed against the tier of blanks and another tier placed against the front of the die -'iand this arrangement of tiers of blanks with intervening dies is continued until the space between the stationary die -D- and follower -F is filled. Then the upper section -B' is swung over onto the lower section and clamped thereon and steam is admitted into the jackets O-O and into the hollow dies and when these parts are properly heated the nut -d is set in motion to force the screw -I- toward the holder B'- B'- and exert the necessary pressure on the follower -F to compress and shape the blanks.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A hot press composed of a longitudinally divided holder adapted to receive int-iers the articles to be compressed, the lower section of said holder being stationary and the upper section removable, a die seated stationaryin one end of the holder the follower in the opposite end of the holder receiving the compressing power, hollow dies arranged movably between the stationary die and follower and riding on the edges of the lower holdersection, and heat conductors communicating with the hollow dies, as set forth.
