IMPROVEMENT IN MACHINES FOR CUTTTINGVENEERvING INTO STRIPS.

The Schedule referred to in these Letters Patent and making pari: of the same.

To all persons to whom these presents may come:

Be it known that I, GEORGE W. MANTON, of Fredonia, ofthe county of Chatauqua, ofthe State ofpk New York, have invented a new auduseful Machine for Cutting Veneer-ing into Strips for the manufacture of such into window-shades, and I do hereby declare v,the same to be iully'described in the following specication and represented in the accompanying drawing, of which- Figure l is a top view;

Figure 2, a side elevation;

Figure 3, a front end view; and

Figure 4, a longitudinal section of the said machine.

The veneering to be reduced to blind-slats by means of this machine is such as is usually made by cutting a spiral sheet from a round log. rlhe sheet, as made, is usually of considerablev length, the grain of the wood running transversely of it. As a conseqncnce the sheet has to be cut transverselyin order to divide it into narrow pieces or slats, which, when woven, or connected edge to edge by warp-threads, extending through a series of them, compose a window-curtain or blind.

Figure 5 is a representationof part'of such a blind, the slats being shown at a a a and .their-connectionwarps at b b b.

1n constructing the machine I employ a frame, A, having two arched guides l5 B arranged above it and upon standards c c, as shown, in order that there may be an open space, d, between each arched guide and the frame-rail d', immediately beneath it.

Between the two arched -guides, which are horizontal and parallel to each other, there is arranged 'upon the top ofthe frame A, or the upper crossrirts e e thereof, a series of stationary bed-hars, f f jl These bars are all parallel to one another, and each is at a short distance from that next to it, and is fastenedto the 'girts e e.`

A series of disk-knives, g, arranged vertically, and at equal distances apart, and so as to extend into the openings or spaces between the bed-bars f, is fixed on a horizontal shaft, h1, having its journals supported in bearings in the two heads t' t', connected by cross-bars 1c lt, so as to compose with such a frame E, as shown.`

Thedieads t t are grooved'on their outer sides to receive and slide upon the base of the arched guides B Br The strip of veneering. to be cnt by the machine is introduced -throu'gh either-of the open spaces d, and thence projected upon the series of bed-bars, and made to rest against one or two of the standards by which theA arched guides are supported.

This having. been done, the frame or carriage of the series .of rotary disk-knives is to beldrawn or pushed forward so as to cause the several knives to crowd the sheet ofyeneering closely down upon the bed-bars and sever such sheet, or the part of it over which the knives may pass, into a series of strips or slats. The strip of veneering may next he advanced a further distance into the machine, to the necessary extent,

and be further operated on by the knives.

I am aware that, for cutting paper or leather into strips o'r bands, it has. been customary to employ a series ot rotary knives and a grooved table, and therefore I make no claim to such in` theabstract.

My machine, besides having the series of separate bed-bars, has the arched guides, arranged with the cutter-frame or carriage, and 'upon standards, as described, in order to render the machine adaptable to the special operation described on a sheet of veneeriug of the kind explained; therefore What I claim as my invention is- The combination ofthe rotary series of disk-knives g, the series o f stationary bed-bars f, the cutter-carriage or frame F, and the arched guides B, arranged with and applied to the supporting-frame A, as and for the purpose as specified.
