DROPI-STAND FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 541,474, dated June 25, 1895.

r Application filed March 13,1895. Serial 110,541,546; (in) mini-e1.)

To all whom it may concern THOMAS KRAEMER, citizens of the United States, residing at'Elizabeth, in the county of '5 Union and State of New J ersey,have invented certain new and useful Improvements in Drop-Stands for Sewing-Machines, of which the following is a specification,'reference be-' ing had therein to thqaccOmpanying-drawwings. I

structedthat the machines,' when not in use,

' may be dropped down beneath the surfaces.

of the tables and the openings in the tabletops be thencovered over by foldingextemsion' leaves so thatthe tables may be-usedfor other purposes than assewingmachine tables; and our invention has for its object to providea sewing machine drop-stand or table,"of the class referred to, which will be strong and durable, and thus little liable to get-out of order, while at the same time it will be'neat and attractive in appearance and convenient in use, as well as simple in construction, so that it may be manufactured at a minimum cost.

In carrying-our invention into efiect we provide a hinged support which is arranged at the right hand end of the opening in the table-top in which the machine bed-plate is received, or at the end of said opening beneath the fly and pulley wheel of the machine.

The said hinged supportis provided with openings for the passage of the driving belt and has also a lip extending beneath the bed plate ofthe machine. Beneath the table, at the rear of the machine, is a torsional coil spring one end of which is held stationary while the other end thereof engages said hinged support so that said spring serves to counterbalance the weight of the machine when the latter is turned down on its hinges beneath the table top.

In the accompanying drawings, Figure 1 is a'front view of a sewing-machine stand embodying our invention. Fig. 2is a plan View of the same. Fig. 3 is a section through the table. Fig. 4 is a detail of one of the hinges 5o connecting the machine bed-plate to the table.

Our invention relates to that class of sew-f ing machine stands or tables which are so con-.

' Figs: 5 and'6 are detail views of the torsional Be it known that we, PHILIP. DIEHL andspring and adjacent parts, I

Adenotes the table having an opening a which receives the bed-plate b of the machine said bed-plate being connected at its rear side 5 5 to said table by double acting hinges" b of such'construction as to permit the machine to be-dropped down below the table-top or tilted over backward above the table when access to the mechanism under the bed-plate isdesired. The bed-plate b isnormally supported at its front side by a hingedleaf A having a lip at extending beneath said bed-plate.- A is an extension leaf which, when the machine is dropped below the upper surface of the table, is folded over, as denoted by dotted lines in Fig. 1,1:0 cover the opening down through which they machine has passed, to render the table fit for use for other purposes than-as a sewing machine table.

O is. a sustaining plate or support placed at the right hand end of the opening a and hinged at its rear end to a bracket 0 beneath the table top, said hinged support having near its front end a lip or lug 0' extending under the machine bed-plate b, and said support being provided with belt openings '0 D is atorsional coil spring surrounding lateral extensions or bars 6 preferably cast integral with bracketsor hangers e, e secured to the under side of the table-A, the bracket or. hanger e being preferably cast integral with the bracket 0 to which the support 0 is hinged. One end at of the spring D extends beneath the support 0 and is received in a groove 0 formed by ribs 0 and the other end d of said spring engages a collarfon the extension e of the bracket e. The collar fis normally held stationary, as by a pin g en gaging a part of the bracket 2 and entering any one of the holes f in said collar. The stress of the spring D may be regulated, to secure the proper tension, by turning the col- 1ar-f in one direction or the other, asf'will be readily understood.

H denotes a box or housing secured to the under side of the table A and serving to inclose the machine and protect the same from dust when it is dropped beneath the table. The lower wall of the housing may also serve roo o r the torsional springis conveyed to the hinged gaged directly with the machine bed-plate.

, enta hinged support located at one end of said machine into said receptacle. spring be properly adjusted it will of itself limit the downwardly swinging movement of 'the machine, said spring being wound up in lowering, the machine, so that its torsional o of the table A.

as a drip pan, or may be metal line for this purpose; I- a Whenthe machine is to be dropped below the table its front side is first lifted slightly so that the hinged leaf A may be raised to bring its lip a out'ofrange of the front edge ofthe machine bed-plate-and the machine may then be lowered into the receptacle beneath the table, and. in this operation the couuterbalancing spring D prevents'any accidental jar oi" strain on the hinges b which might otherwise result in thus lowering the In fact it said stress is increased. In lifting the machine to working position the operation is assisted by the spring D as will be understood, so that butlittle force is required to be exerted by the operator. 7 T 1 When, the machine is tilted over above the table for access to the works beneath the bed plate, the support 0 is prevented from being lifted above the table Aby the engagement of the rear end of said support with the part The part 0, although herein termed a, sup port, does not sustain the machine whenthe latter is in working position, the machine, at such times, being supported by the hinges band the lip a of the hinged leaf A. The support 0, in its normal orraised position, is, preferably flush with the top of the table A and thus practically forms an extension of the machine bed-plate b which is of less length than the opening a, said support and bedplate together just filling the said opening.

lVe do not wish to be understood as limiting our invention to all of the details herein shown, as these details may be varied considerably without departing from the spirit of our invention.- For example, the machine bed-plate hinged to the table at one side might be supported at its opposite side by sliding latches or other movable equivalents for the hinged leaf A with its lip a. Also instead of employing the hinged support 0, through the medium of which the stress of bed-plate of the machine, said support might be dispensed with and the said spring en- Having thus described our inventiomfwe claim and desire to secure by Letters Pat-.
