E. J. BALMOS FOLDING CHAIR FOR SEWING MACHINES Filed Oct. 11, 1929 3 Sheets-Sheet 3 Patented July 19, 1932 UNITED STATES EDWARD J. BALMOS, or nnvrnn, Tnxns FOLDING CHAIR FOR SEWING MACHINES This invention aims to provide a novel chair, so constructed and mounted that, when the occasion for its use has passed, it may be folded away, to assume an inconspicuous 1'5 position within the contour of a sewing machine. The invention aims to provide novel means for mounting the seat for movement toward and away from a sewing machine, and to supply novel means for regulating '10 the movement of the seat.
It is within the province of the disclosure to improve generally,rand to enhance the utility of, devicesof that sort to which the invention appertains.
With the above and other objects in view, which will appear as the description proceeds, the invention resides inthe combination and arrangement of parts and in the details of construction hereinafter described 50 and claimed, it being understood that changes may be made in the precise embodiment of the invention herein disclosed, within the scope of what is claimed, without departing from the spirit of the invention.
In the accompanying drawings Figure 1 shows, in side elevation, a device constructed in accordance with the invention, connected to a sewing machine;
Figure 2 is a vertical longitudinal section 30 of the device forming the subject matter of this application;
Figure 3 is a rear elevation;
Figure 4 is a bottom plan of the seat;
Figure 5 is a sectional view showing the shaft and attendant parts.
The numeral 1 marks a sewing machine including a body 2 and legs 3. Parts 4: of the legs 3 form an angle portion 5 in the legs.
The chair forming the subject matter of this application includes a seat 6, which may be of box-like form, to provide storage room, the seat being supplied with a hinged lid. On the back of the seat 6 are mounted rearwardly extended, U-shaped brackets 7 in which connections 8, in the form of pins, are mounted removably. The connections 8 are supplied with abutments 9, which, cooperating with the upper portions of the brackets 7, limit the downward movement of the connections or pins 8.
Application filed October 11, 1929. Serial No. 398,969.
- The numeral 11 designates a chair back including depending standards 12 connected'by a pivot rod mounted to turn in the upper ends of the connections or pins 8. The upper ends of the connections 8 and the lower ends of the standards 12 of the back 11 preferably are flattened and halved together, as shown at 14 in Figure 3. At their lower ends, the standards 12 of the back 11 are supplied with depending fingers 15 (Figure 2) which, bearing against the pins 8, limit the rear} ward swinging movement of the standards 12 and hold the back in the position shown in Figure 2. V
The numeral 22 marks an angular link, the upper end of which is mounted at 23 to swing on the intermediate portion 17 of the support 18, between the bearings 16, .in a way which will be understood when Figure 4 of the drawings is noted. The upper portion of the link 22 fits in a trough-shaped socket 24. carried by the bottom of the seat 6. The lower endof the link 22 is received for sliding adjustment in a guide 25, a projection 26 (Figure 5) on the link 22 cooperating with the guide to prevent the link'from'being withdrawn completely from the guide 25. A spring-actuated latch 27 is mounted on the guide 25 and cooperates with a hole or keeper 28 on the link 22.
Diverging arms 29 connect the guide'25 with a bearing 30 mounted to turn on the circular portion 31 of a tubular member 32, between shoulders 33 on the said tubular member. The ends 34 of the tubular member'32 are squared, and in the ends 34;, extension rods 35, preferably square in cross section, are held against rotation. The eX- tension rods may be adjusted lengthwise in the ends 3 L of the tubular member 32, and may be held in any position to which they have been adjusted,through the instrumentality of latches 37 carried by the ends 34: of the tubular member 32 and adapted to engage with seats 36 on the rods 35. On the ends of the rods there are upwardly and outwardly extended angular hangers 38 which are received in the angles 5 formed by the parts 4 of the sewing machine frame. The hangers 38 are supplied at their outer ends with enlarged heads 39 engaged with the parts of the sewing machine frame, and keeping the hangers 38 in place in the angles 5 of the sewing machine frame.
The tubular member 32 and the extension rods 35 may be alluded to as a longitudinally extensible shaft, enabling the device to'be mounted on sewing machines, regardless of the distance between thelegs 3 of the sewing machine frame. The support 18 rests on the floor, as shown in Figure 1', the upper part of the link 22 is received in the socket 24, the latch 27 of Figureh is engaged in the keepers 28 of the link 22, and the seat 6 held securely in the position delineated in Figure 1, so that a person occupying the seat can work conveniently at the sewing machine 1. 1f the operator does not careto have a back, he can remove the back 11, the pins 8 being pulled out of the brackets 7 on the seat 6. If, however, the back 11 is used, it may be folded forwardly to rest on the seat 6.
The latch 27 is disengage-d from the 28 in the link 22, and the link 22 slides down in the guide 25 until the-lower end of the link rests on the bearing 30. This shortens the link 22 so that the seat can move forward under or into the sewing machine body, as shown in dotted line in Figure 1, the bearing 30 of Figure 5 rotating on the circular portion 31 of theshaft 32 35, and the link 22 swinging forwardly into thedotted. line position of Figure 1.
' 4 -The device is very simple in construction,
but it affords a means whereby a person working at a sewing machine can have a comfortable seat, the seat being housed within the contour of the sewing machine, when the occasion for; the use of the machine has passed. 1
- Having thus described the invention, what is claimed is: V r
1. In a device of the class described, a tubular member having shoulders, a bearing mounted to turn on the tubular member, be-
tween the shoulders, extensions held against rotation in the ends of the tubular member,
latches affording a stepby-step longitudinal adjustment of the extensions in the ends of connecting the leg and the link pivotally with the seat. r
2. In a device of the class described, a tubular member, a bearing mounted to turn on the tubular member, means for Supporting the tubular member for turning movement about an axis, said means comprising an extension rod held against rotation in one end of the tubular member, a latch affording a step-by-step longitudinal connection between the extension and the tubular member, a guide mounted on the bearing and disposed approximately at right angles to the bearing, a link longitudinally adjustable in the guide, means for holding the link in loi'ig'itudinally adjusted positions in the guide, a seat, a leg, and means for pivotally connecting the link' and the leg with the seat. 3. A folding chair forsewing machines and the like, comprisinga chair having a seat, bearings mounted on the under side of;
seat, in front of the bearings, the upper member of the link extending forwardly and horizontally through the trough-shaped bracket, and extending downwardly, ahead of the bracket, to form a lower member in the link, said lower member of the link being disposed at an obtuse angle to the upper member of the link, and means' for connecting the lower end of the lower member of the link pivotally with the sewing'machine or the like with which the chair cooperates.
In testimony that I claim the'foregoing as my own, I have hereto afiixed my signature.
