To all whom it may concern:

Be it known that -I, THEODOR KUNDTZ, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Sewing-Machine Tables; and I-do hereby declare the following to be a .f ull, clear, and exact description of the invention, such as will enable others skilled use the same.

My invention relates to sewing-machine tables of the cabinet variety and having means for' depressing the head of the machine below the line of the table, and having means for automatically shifting the head toward and from the line of the ily-wheel in raising and lowering the head. v l

In the accompanying drawings,Figure 1 is a front side elevation of a sewing-machine` table or cabinet embodying my invention, the head of the machine being shown in position for operation. Fig. 2 is a top plan of the same, portions being broken away and'in section to reduce the size of the ligure and to vmore clearly show the construction. Fig. 3 is a front side elevation of the table or cabinet,

ered position, portions being broken away and in section. Fig. iris an elevation in secchine-head removed. Fig. 5 is a rear side elevation of the table or cabinet, showingv the portions being broken away to more clearly A A represent the end walls of a sewingmachi'ncabinet; B the table-top, and C the bars A' A', located a suitable dist-ance apart and secured to ithe rear wall of the cabinet, are grooved vertically on their inner faces, as in these grooves operate the ends tends 'forward somewhat like a shelf, as at D', and on this shelf is mounted a sliding-frame E, the frame andthe shelf being tongued and on the shelf without losing its lateral alignment. The head C is mounted Von,'and, rig-v `idly secured to frame E.. 'i u i vshifted automatically in A the carrier, and the latter is operated by fold- B' is a folding-leaf hinged to the table-topl at B. To this leaf at or near the rear edge thereof and some little distance from the axialV line or hinges, is secured, as at F', the ilexible member F, preferably a thin metal strap. This strap passes over a small roller or wheel S, connected with the table, and thence mem ber F connects with the carrier, Ethe attachment being preferably by means of an eyebolt f Ifurnished with athmbmnt f', by manipulating which the length of the strap may. be adj usted so that when the leaf is extended, as shown in Figs. 1 and 2, the carrier will be drawn up with frame Ein position flush with the table-top, the latter haviuga suitable central opening to receive the frame. From the under side and rear edge ofl the table depends the inclined block Ghaving a groovegin the front face thereof. Connected with the'rear -edge of frame E is an inclined tongue or member e adapted `to operaterin groove g aforesaid. .As the carrier is being elevated meml ber e enters groove g whereby a further upward movement of the carrier causes the frame to be moved endwise in the direction of the ily-wheel H, the relation of parts being such that, when the head is in its elevated or working position, as shown in Figs. 1'- and 2, the band-wheel thereof is supposed to be in line with the fly-wheel. In depressing the carrier, the motion of frame E is of course re-Y versed so that the frame and head clear the-V ilyiwheel. The head andframe arethus raising and lowering ing and unfolding theleaf B'. When the head `is depressed, in accomplishing which the leaf B' is folded back over all, as shown in Figs. 3 and 5, the leaf in that case covers the opening in top B, whereupon the leaf serves as the table-top during its folded position.

I is a dat spring secured side of frame E, (see Figs. 2 and 4) this spring having attached a catch or dogl i, the dog having preferably a conical free end. With frame E in'its elevated position,

the dog engages a corresponding holeb inthe the conicalend of table-top, and thereby locks the frame, holding the frame and load rigid in'ts elevated position. Meantime the carrier supports the Y, g, frame and load,'bnt the silice of the dog is to the innerfront Y Ywould be s'nstained by the dog, were it able to do so, but the spring is not stiff enough for such purpose and the dog isforced back, after which they frame is free to descend with the carrier. As, therefore, the catching and releasing occurs automatically, theoperator is released from all care in the matter, and when the machine is in working position it will be as stable' as if itv rested on the table- Y the matter,

` chine table or cabinet top. Were the locking of the frame done by hand, any inadvertance of the operator in would leavel the head in such tremulous or shaking condition as would interfere with the perfect working of' the machine andcanseexcessive wear at the joints, which diiiicnlty is overcome by the automatic locking aforesaid. c

A designate doors for closing the forward side of the cabinet, said doors being hinged at a2.' The rear wall of the cabinet is provided with an opening A4, for the purpose of ,ventilation in the operation of the sewingmachine, said opening being adapted to be closed by a door Aa hinged, as at as, and a catch is provided at a." for locking the door in its closed position.

What I claim is- 1. In combination, a cabinet lsewing-mahaving a carrier movable n p and down the cabinet, a/horizontallysliding-frame borne by the carrier and designed to bear the sewing-machine-head, a stationary inclined way or guide, and a member on the aforesaid sliding-frame adapted to engage said way or guide, the arrangement of parts being such that the aforesaid slidingframe and load shall be moved horizontally 'during the np-and-down movement of the aforesaid carrier, substantially as and for the purpose set forth. g

2. In combination, a cabinet sewing-machine table havinga vertically-reciprocatingcarrier, a horizontally-sl'iding-frame mounted on the carrier, such frame bearing the head,

a stationary inclined way or guide, an attach- L i ment of the-frame adapted to` engage-such way or guide, for shifting the frame and load horizontally by means of .the vertical movement of the carrier, substantially as and for the purpose setvforth. t

3. In combination, a sewing-machine table or cabinet having a carrier, folding-leaf operatively connected with-the carrier for raising and lowering the latter, a sliding-frame borne byand movable endwise of the aforesaid carrier, astationary block provided with an. inclined groove, and a member yon the aforesaid sliding-frame and adapted to operate in said inclined groove, the arrangement of parts being'substantially asset forth.

4. In combination, a sewing-machine-table having a carrier, and folding-leaf operatively connected withthe carrier, for raising and lowering the latter, a frame mounted on and movable endwise of the carrier, a pendent stationary block attached to the table and having an inclined groove, a member of the frame adapted to operate in such inclined groove, the arrangement being substantially as described.

In testimony whereof I sign this specitication, in the presence of two witnesses, this 9th day of June, A. D. 1894, atUleveland, Ohio.
