SEWING-MACHINE TABLE.
SPECIFICATION forming part of Letters Patent No. 552,507, dated January 7, 1896,.
Applicants nea April 41o, 1893.
To all whom, it may concern:
Be it known that I, JAMEs BOLTON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sewing Machine Tables, of which the following is a specification, reference being had therein to the accompanying drawings.
My invention relates to sewing-machine tables or stands, and more particularly to that class thereof which are so constructed as to permit the sewing-machine, when not in use, to be dropped down below the surfaceof the table, so that by folding down'the leaf which forms an extension of the table, onto the surface of the latter, the opening in the table proper is covered,and thus the table is adapted for use as an ordinary table, this class of stands being known to the trade as dropcabinets.
The object of my invention is to provide a brace for the class of sewing-machine stands or tables referred to, which brace is of such construction that the driving-wl1eel of the machine may be mounted thereon and be out of the way of the operator, the brace being so made that it may be quickly and cheaply secured to the legs or side frames of the table, and the screws by which the bottom portions of the brace are secured to the said legs or side frames serving also as center screw-bear ings for the treadle. The bearing for the driving-wheel is of such construction that it may be adjusted to compensate for wear.
In the accompanying drawings, Figure l is a front view of a sewingmachine stand embodying my invention, the legs or side frames of the stand and the table portion thereof being denoted simply by dotted lines. Fig. 2 is a detail sectional view of the bearing for the driving-wheel. Fig. 3 is a detail sectional view of one of the bearings for the treadle, and Fig. 4C is a partial cross-section showing the receptacle for the machine when the same is dropped beneath the table.
A A denote the legs or side frames of a sewing-machine stand or table, these being usually of cast-iron.
B is the table portion of the stand, and C denotes a receptacle beneath the table into serai No. 469,779. (No model.)
which the machine may be dropped when not in use.
The sewing-machine (denoted by dotted lines in Fig. 4) is mounted upon a hinged section h of the table B, said hinged section b being supported in front by a second smaller hinged section b, which, when the section h is lifted slightly, may be turned upward to permit the said section Z2 with the sewingmachine mounted thereon to fall down below the table B into the receptacle C in the direc tion denoted by the arrow in Fig. 4. The brace which connects the legs or side frames A, and which serves to stiifen and steady the table, comprises the curved outer vertical parts or bars d and the horizontal bars d d2, the latter having the extension d?.
The outer ends of the upper horizontal bar d are screwed or bolted to the side frames A in any suitable manner, and the lower ends of the bars d are secured to the said legs or side frames by means of screws a, tapped through the said legs or side frames and passing loosely through the lower ends ofthe bars d of the brace, the said screws being rounded or pointed at their inner ends to serve as center or bearing screws for the treadle E, which is mounted thereon, as more clearly shown in Fig. 3, setnuts a being provided to hold the screws in any desired position of adjustment to firmly lock the lower ends of the brace to the legs or side frames of the table.
The upper horizontal arm d serves as a support for the box or receptacle C, which incloses the machine when the latter is dropped below the table. The part d3 of the lower horizontal bar d extends outside of one of the vertical bars d and is preferably formed conical at its outer end, as shown in Fig. 2, so that it may fit in a oorrespondingly-shaped recess or countersink in the inner side of the hub of the driving-wheel F, the outer side of said hub being also countersunk for the reception of the conical head on the screw f, which is tapped into the extension or bar d3, and which screw serves as a bearing for the said driving wheel. The screw f may be turned, when desired, to compensate for wear at the hub of the driving-wheel, and is secured in. any desired position of adjustment by the set-screw f.
By arranging the driving-wheel, as shown,
IOO
outside of one of the curved Vertical bars of the brace,the latter, it will be observed, serves as a guard to prevent the dress of the operator from coming in contact with the drivin g-wheel or with the pitman g, which connects said wheel to the treadle E.
It will thus be seen that by the simple form of brace herein shown and described I am enabled to provide an eiicient compensating bearing for the driving-wheel, and a bearing for the treadle as well as a dress-guard, while the brace itself, although simple in construction, serves as a support for the receptacle C and strongly braces the whole table and renders it firm and efficient.
Having thus described my invention7 I claim and desire to secure by Letters Patent-- l. The combination with the table and legs or side frames of a sewing machine stand provided with a receptacle into which the sewing machine may be dropped when not in use, of a brace connecting said legs or side frames and to the outer part of one side of which the driving wheel is j ournaled, said brace having an upper cross-bar serving as a support for said receptacle and being provided at its lower end with screws which serve to secure the same to said legs or side-frames of the stand and which also serve as bearing screws for the treadle.
2. The combination with the legs or side frames of a sewing machine stand, of atablc attached to the tops of said legs or side frames, a receptacle beneath said table into which the sewing machine may be dropped when not in use, and a brace connecting said legs or side frames and to the upper part of one side of which the driving wheel is journaled, said brace having an upper cross bar serving as a support for said receptacle, substantially as set forth.
In testimony whereof l affix my signature in presence of two witnesses.
