GEORGE M. RAMSAY, OF NEW YORK, N. Y.

, M01.13INer-rapaci-Iliana.-

Speccationof Letters Patent No. 12,243, dated January 16, 1855.

To all whom t may concern.'

Be it known that I, GEORGE M. RAMSIAY, of the city of New Yo-rk, in the county and State of New York, have invented an Improved Sash-Blind or Molding Machine; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reference beinghad to the annexed drawings, and letters of reference marked thereon, making a part of this specification, in which- Figure 1, is a top or plan view, Fig.v 2, va vertical longitudinal section.

The nature `of my invention consists in the construction of a double action, rotary, sash-blind, or molding machine, with but one cutter-head-feed rollers and guidepieces, connected in such a manner as to work the two opposite sides of the same piece of stuft' by once passing through the machine, each side being worked with 'the grain, and cutting from within outward, against the feed; also, in iluting my feedrollers diagonally (or spirally) in order to produce a pressure at right'angles against the guide-piece and bed at the same time. Also, in arranging a fan, revolving within a cone, and placed above the cutter-head, for the purpose of blowing the shavings underneath the machine.

To enable others skilled in thev art to make and use my invention,.I will proceed to describe its construction and operation.

Fig. 1, is a top or plan view. Fig. 2, is a vertical longitudinal section.

Similar letters refer to like parts.

A, representsl the frame, made of any suitable material of sufficient solidity, and dimensions suited to the size of the machine, and forms the bed upon which the stuff to be operated on rests. B, and C, are two guide-pieces resting thereon, and are for the purpose of conducting the stuff toward the cutter-headon itstwo opposite sides.

F, is the cutter-head attached to, and revolving with a vertical shaft, operated by a belt from pulley b.

I, H, P, Q, are -feed-rollers, operated by belts, from pulleys, upon the same shaft of pulley Z).

K, L, R, S, are ordinary keepers to retain the stuff in proper position.

M, is a feed roller capable of revolving upon the end of spring, N, and on the lower end of roller, M', underneath the bed part of frame A, is a gear wheel, madeto work into a similar wheel W, upon a vertical shaft operated upon by a belt from a pulley upon a vertical shaft of feed-roller P. The feed-rollers are fluted diagonally in order to exert a pressure at right angles (through the medium of the stuff) against the bed of frame, A, and guide-pieces B and C, at the same time.

The guide-pieces, B and C, and spring, N, in connection with ro-ller, M, and gearwheel, W, are for the purpose of reversing the4 stuff, and presenting the opposite side and end of the samev piece of stuff to the op- ;posite side of the same cutter-head. The laction of the roller, M, and spring, N, is I automatic and intermittent. The rest, pivot,

or ro-ller, T, is the point at which the stuE is poised, while in the act of being reversed, and is made movable to suit different lengths of stuff. Above the cutter-head, I place a hollow cone, Z, Fig. 3, containing within it a fan, g g, attached to and revolving with same shaft of the cutter-head. The wings of said fan are placed at such angles as to produce a current of air downward for the purpose of blowing the shavings underneath the machine.

X, represents a piece of stuff in the act of y being fed to the machine, and, Y, the same, or another piece making its entrance at roller, P, by the aid of roller, M.

The end of frame,'A, marked, a, 1, is cut at an obtuse angle, in such a manner as to cause the finished stuft` to fall outward from the machine.

Having thus fully described the construction of my invention, I shall next explain its operation. r

Having adjusted my guide-pieces, B, and C, and spring, N, with rest, T, to suit `the kind of stuff to be worked, I set the machine K in motion and feed in the piece X, which is carried to and past the cutter-head by rollers, I, H, against the spring, N. Said spring is pressed back in the position of, M, on frame, A, until the piece, X, is clear of keepers, L, K, and poised upon the rest, T, then yby the automatic action ofspring, N, the piece is instantly pressed over against the opposite guide-piece, C, while simultaneously the roller, M, is made to revolve by its connecting underneath .with gear-wheels, W, and thus the piece, X, is reversed, and assumes the position of, Y, and is fed to rollers, P, Q, which passes through and makes its exit at, A, 1. Thus the two opposite sides of the same piece of stu are worked alike, with the grain, and against the feed while the action of the cutter-head is from the worked to the unworked surface, on each side, all by the double action of one cutterhead, feed-rollers and guide-pieces connected and operating as herein described. By this arrangement of mechanism I increase the capacity of the machine more than doubly, as it enables me to do the same quantity of work with half the labor, and in less than half the time; as I save all the time and labor required to readjust the machine, gather up the stuff, and carry it to the other end of the machine for the purpose of running it through the second time My manner of iuting the feed-rollers enables me to dispense with one 'set of keepers, ordinarily used to keep the stuff close to the bed.

The advantages arising from my manner of clearing the shavings, and of dropping the finished stuff from the machine is obvious to all those skilled in the art of using said machine.

I deem it unnecessary to make the frame, A, wide at one end and narrow at the other, as the reversing-point, T, may be governed by the guide-pieces, B, and, C, alone, nor is the rest, T, indispensable; as the same office or function may be performed by making the guide-pieces, B, and, C, to slide back and forth. I, also, contemplate making my feed-rollers and keepers movable; also, my spring, N, wit-h roller, M, may be made to shift back and forth, and connect underneath with a bevel wheel made to shift or slip upon a horizontal shaft to suit the position of said spring, and feed-roller, M. But these contemplated alterations shall not be so construed as to impinge upon my claim as based upon the preceding specification, as those alterations will not be required eX- cept when it is desired to work the two opposite sides, at one operation, of great eX- tremes in length.

I am aware that there are machines in use which work the two opposite sides of the same piece of stuff by once passing through the machine. I am also aware that one cutter-head is required (in those machines) to work each of those opposite sides. I am also aware that when two cutter-heads are used, and are made to revolve in the same direction, to cut against the feed, that one of these sides must, 'of necessity, be worked against the grain; and to reverse one of the cutters to suit the grain the defective quality of the work is even greater by reason of cutting with the feed and against the sand Y and dirt on the outer side of the stuE. These same defects follow where four cutter heads are used to the four sides of the same piece of stuff. Therefore I do not claim the mere fact of working the two opposite sides of the same piece of stuff by once passing to and through the machine but,

What I do claim as my invention and desire to secure by Letters Patent of the United States is i The -automatic reversible feed (or its equivalent) whereby the two opposite sides of the same piece of stu is worked (in the manner herein described) by the double action of one cutter head, by once passing the stuff to and through the machine, also the arrangement of the cone and fan, all operated and operating substantially in the manner and for the purpose herein set forth.
