CABINET FOR SEWING-MACHINES.

$PECIFIGATION forming part of Letters Patent N 0. 565,623, dated August 11, 1896.

Application filed September 7, 1895. Serial No. 561,784. (No model.)

To all whom it may concern.-

Be it known that we, THEODOR KUNDTZ and RUDOLPH KOSOH, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Cabinets for Sewing-llfachines, 85c. and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

Our invention relates to improvements in cabinets for sewing-m achines, (be. and it consists in certain peculiarities of construction and combination of parts hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a front side elevation of a sewing-machine cabinet provided with our improvements. Portions are broken away and in section in this figure to reduce the size of the drawing and to more clearly show the construction. Fig. 2 is a front side elevation, partly in section, of the cabinet; and Fig. 3 is a top plan in horizontal section on line 3 3, Fig. 1. Fig. 4: is a transverse vertical section on line 4 4, Fig. 2. i

The sewing-machine head is represented by broken lines. In Fig. 1 the carrier that bears the sewing-machine head is shown in its elevated position in solid lines, and said carrier and the folding leaf that is hinged to the top of the cabinet and operatively connected with the carrier are shown in dotted lines in the operation of lowering the carrier. In Fig. 2 the carrier is shown in its lowered position.

Referring to the drawings, A designates the rear wall of the cabinet, and A andA the left-hand wall and right-hand wall, respectively, of the cabinet. The upper portion of the rear wall of the cabinet is provided with a stationary panel A (shown in Figs. 2 and 3,) and the lower portion of the rear wall of the cabinet is provided with an opening a (shown in Fig. 1) for accommodating a circulation of air through the cabinet. Opening a is adapted to be closed by a vertically-sliding carrier B, that is adapted to slide up and down the rear wall of the cabinet forward of and in close proximity to panel A The rear right bars A, located a suitable distance apart and provided upon their opposing faces with vertically-arranged grooves or ways A, that are engaged by rollers or wheels I) of carrier B and are long enough to accommodate the operation of said carrier. Carrier 113 at its upper end is provided with a forwardly-extending horizontally-arranged shelf or plat form I3, that is designed to bear the sewingmachine head or other machine that is elevated above the cabinet preparatory to its operation and lowered within the cabinet when not in use. Platform or shelf B is preferably supported from carrier B by means of two metallic brackets B secured to the forward side of the carrier.

A sewing-machine head Ois shown in dotted lines in the case illustrated, and in the case of a sewing-machine cabinet the head C does not rest directly upon shelf or platform B, but is mounted upon a sliding frame E, that, upon its under side, (see Fig. 4,) is pro vided with tongues c, engaging and adapted to slide endwise of grooves or ways 19, formed in said platform or shelf, which grooves and tongues are arranged parallel with the rear wall of the cabinet, so that frame E is capable of sliding in a direction parallel with said wall of the cabinet.

D designates a folding leaf hinged at D to the left-hand end of the top of the cabinet. To this leaf, at or near the rear edge thereof and a suitable distance from the axial line or hinges, is pivoted one endof a metallic rod or bar G, as at g, and said bar or rod at its opposite end is pivoted to an upright metallic arm H, that is suitably secured to carrier B. Folding leaf D is suitably recessed, as at d, to accommodate the reception of rod or bar G flush with the upper surface of said leaf, and the top of the cabinetis suitably recessed or slotted, as at a, to accommodate the location and operation of member Gr. It will, therefore, be observed that arm H and rod or bar G establish operative connection between carrier B and folding leaf D, and that said shelf or platform and its load is elevated or lowered according as folding leaf D is brought into line with the cabinet-top, as

wall of the cabinet is provided with two upshown in solid lines, Fig. 1, or closed down over opening (1 with which the cabinet-top is provided, and which opening is designed to receive the sliding frame E in the case illustrated, flush with the top of the cabinet.

We would here remark that the rear edge of frameE is provided with an inclined tongue or member E, adapted to operate in a correspondingly-inclined groove or way 1, formed in a block or member I, depending from and suitably supported by the top of the cabinet, and the arrangement of parts is such that as carrier B and the shelf or platform connected therewith are elevated, tongue or member E enters groove or way 1, whereby a further upward movement of said carrier causes said frame E to be moved endwise in the direction of the fly-wheel K, and when the sewingmachine head is in its elevated or working position, as shownin Fig. 1, the band-wheel thereof is supposed to be in line with the flywheel, and in lowering the sewing-machine head the motion of frame E is, of course, reversed, so that said frame and the sewingmachine head thereon shall clear the flywheel. The head and frame are thus shifted automatically in raising and lowering carrier B, and said carrier is operated by folding and unfolding leaf 1), and when the sewing-machine head is lowered leaf D is folded back over all and closes opening a in the cabinettop, as shown in Fig. 2.

The means employed for automatically shifting frame E toward and from the flywheel forms no part of our present invention, but the peculiar means establishing operative connection between carrier B and folding leaf D does form a part of our present invention, and we would here remark that bar or rod G, upon its under side and in suitable proximity to its connection with arm H, is provided with a hump G, adapted to engage an inclined wall (4 with which the recess or slot a in the cabinet-top is provided, when the sewing-machine head, in actuating said head from its lower or inoperative position into its elevated or operative position, has almost reached its extreme upper position during said actuation thereof, and thereby serves as a fulcrum, and hence it will be observed that said link G, when its hump, during the elevation of the sewing-machine head, engages the aforesaid inclined wall, whose trend is upwardly and outwardly in the direction of the hinged end of folding leaf D, constitutes a lever whereby the sewing-machine head is lifted into its extremeupper position.

The arrangement of parts is preferably such that carrier B and its load shall have been actuated into their extreme upper position before hump G of rod or G has reached the upper extremity of inclined wall a and said wall is preferably composed of or lined with metal to render it sufficiently durable.

Preferablya spring S is secured at its lower end to the ,lower portion of carrier B and is suitably attached at its upper end to the top of the cabinet. Said spring is designed to counterbalance, or approximately counterbalance, the load of the carrier. The spring has little or no tension in the elevated position of the head, but is placed under tension upon lowering carrier B, and consequently sustains the weight of the sewing-machine head or carrier-load in lowering the latter, and the spring, of course, also facilitates the actuation of the carrier and its load from their lower or inoperative position to their upper position.

.What we claim is In combination, the cabinet having a carrier movable up and down, which carrier is provided with a shelf or platform upon which the load to be elevated or lowered, as the case may be, is supported; the folding leaf D for operating the carrier, said leaf being hinged, at one end, to the cabinet-top; the inclined wall a provided in the cabinet-top and having its trend upwardly in the direction of the hinged end of the folding leaf; the metallic upright arm H suitably secured to the upper end of the carrier, and the metallic rod or bar G pivotally secured at one end to the folding leaf a suitable distance from the axis of the leaf, and pivotally attached, at its opposite end, to the aforesaid metallic arm of the carrier, said bar or rod having the hump G upon its under side, and the folding leaf and cabinet-top being suitably recessed or slotted to accommodate the location and operation of the aforesaid bar or rod, substantially as shown, for the purpose specified.

In testimony whereof we sign this specification, in the presence of two witnesses, this 31st day of August, 1895.
