D. CUMMINGS, OF NORTH ENFIE'L'D, NEW'HAMPSHIRE.
MACHINERY FOR MORTISING FRAMESl 0F WINDOW-BLINDS.
Specification of Letters Patent No. 10,403, dated January 10, `1854:'.
To all whom t may concern:
Be it known thatI I, D. M. CUMMINGS, of North Eneld, in the county of Grafton and State of New Hampshire, have invented a new and Improved Machine for Forming Mortises in the Stiles o-f lVindow-Blinds; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of Vthis specification,
Figure 1 being a plan o-f the machine, Fig. 2 a front elevation thereof, and Fig. `3 a view of a part detached.
Like letters designate corresponding parts in all the figures.
The stile to be mortised is placed on a movable platform (handl is attached to a gage H, being pressed against projecting points r, r, on t-he side of said gage by two cam-levers o, o, kept parallel and operated simultaneously by means of a connecting rod lw. Said gage slides endwise, and is provided with a series of notches n, n, &c., in its upper edge, at uniform distances apart equal to the required distances of the slats of the blinds from one another; and a projection t, on the lower side of a vibratory lever p, lits into any one of said notches, and thus prevents the gage from moving. In operating the gage, the said projection t, is raised from its notch by pressing down the opposite end of its lever p, and the gage is moved along another notch, whereupon a spring s, pressing down upon the lever p, forces the projection t, into the notch then brought under it.
I cut the mortises by means of a gouge-bit h, or a series of such bits, arranged in the following manner: The bit is caused to revolve in an adjustable bearing-block d, attached to a bar B, extending across the frame of the machine. A band o, passes around the pulley z', on the shaft of the bit, and around the driving shaft A. Said shaft of the bit is made to move endwise suiicient to bore to the requisite depth of the mortise, and to allow it to be raised above the stile, when not boring, by means of a spring y'. When the b-it is to be put in operation, its shaft is pressed down to the stile by means of a curved pin g, attached to a rockingshaft E, which is caused" to vibrate for that purpose by a handle lo. A single bit may be used for forming the mortises successively; or a series of bits equal in number to the number of mortises, may be employed, in
order to form all the mortises simultaneously; or any intermediate number may be used, and placed at suitable and uniform distances apart, so as Vto cut any convenient number of mortises at one time. I usually make a slot f, in the bar B, extending nearly l its whole length, into which the bearingblocks CZ, d', &c., of the bit-shaft, are inserted, and secured by screws e, e, &c., so as to havethem adjustable or removable at pleasure. In that case, the curved pinS g, g', &c.,' should be correspondingly adjustable upon the rocking-shaft E.
While the platform C, remains stationary, only the ends of the mortises are formed by the bits. In order to give the requisite length and Obliquity to said mortises, I cause the platform C, to move in slots g, Q, formed in ways Gr, G, which vibrate on pivots ascending from the sill D, of the frame, in positions directly beneath the slot-guides 0, 0, of the platform. The ways are kept parallel and vibrated simultaneously by means of a connect-ing rod u. The slots are of the proper length to allow the platform C, to slide a sufficient distance to form the mortise of the desired length; and by turning the ways G, Gr, on their pivots, their slots may be adjusted to any angle that it is desired to cut the mortises at. Springs c, c, or their equivalents, serve to draw the platform C, back to the rear ends of the slots. The bits it, h', &c., are rst pressed down, to form one end of their respective mortises; then, the platform C, is gradually drawn foryward to the front ends of the slots, the bits being kept down and revolving in the meantime, by which operation the mortises are finished. The platform is then allowed to be forced back by its springs c, c, and the bits to be raised above the stile b-y their springs y', y', &c., in order to allow'thestile down by a separatev lever Z, because it is never used simultaneously with the mortising bits. When it is desired to bore the lower half of the stiles for rolling-shades, and mortise the upperv half for fixed shades, all the mortising bits are removed except one, h', which is adjusted at a-proper disof Window blinds, What I claim as myv in-` vention and desire to secure by Letters Patent, isv y The movable platform C, spacing gage H, and oblique Ways G, G, when combined and arranged with each other Vand with the adjustable gouge bits 71 k &c., (or theirequivalents) in such a manner that the `mortises formed Will be exactly equidistant from each other, and also in such a manner that any desired degree of inclination may be given to the said mor-tises substantially as herein set forth; disclaiming the use of the said movable platform C, save When employed in combination with the said spacing gage and oblique Ways as above set forth.
The above specification of my improved manner of forming mortises in thev sides of `window blinds, signed this 31st day of lVIarch ,1853. Y
D. M. cinnuiives.`
