BUTTON SEWING MACHINE Filed'March 7, 1940 2 Sheets-Sheet 2 Patented Aug. 11, 1942 UNITED STATES PATENT OFFICE BUTTON SEWING MACHINE Jacob Dashew, Baltimore, Md.
Application Mar-ch 7, 1940, Serial No. 322,666
1 Claim.
This invention relates to improvements in button-sewing machines and has for its object to provide means for throwing the machine into operation after the button has been placed in position to be sewed on to the goods. The means for throwing the machine into operation is so arranged that the operator will have to remove her hand from the button before the machine can be thrown into operation, thereby avoiding any possibility of her finger being caught under the needle. v
The invention consists of the novel construction and arrangement of the parts and combination of parts hereinafter more fully set forth in the following specification, and pointed out in detail in the appended claim.
In the accompanying drawings:
Figure 1 is a side elevation of the upper portion of a button-sewing machine having my invention applied thereto.
Figure 2 is a top plan View of Figure 1.
Figure 3 is a bottom plan view of Figure 1.
Figure 4 is a section on the line 4-4 of Figure 5.-
Figure 5 is an enlarged detail view of a portion of the sewing machine bed and lever for operating the mechanism to throw the machine into operation.
Referring to the accompanying drawings, forming part of this specification, and in which like reference numerals designate like parts throughout the several views thereof, l designates the bed of the machine, 2 the standard, 3 the overhanging arm, and 4 the head of the machine. The mechanism mounted in the standard, overhanging arm and head 4 for reciprocating the needle 5 is of the usual construction. The machine is driven by an electric motor (not shown) from which a belt passes to the pulley 6 which is loosely mounted on the shaft 1 from which power is transmitted to the mechanism for reciprocating the needle. The pulley 6 is integral with the sleeve 8 on the outer end of which is also an integral grooved wheel 9. The inner surface of the pulley 6 is provided with a lug l adapted to cooperate with the arm II which is held fast on the shaft 1 by the set screw 12. A rock shaft 13 is mounted in the lower surface of the bed I and adapted to be oscillated and has an arm l4 secured to the outer end thereof on the free end of which latter is a cam which operates in the grooved wheel 9 to throw the pulley 6 into operation with the arm H on the shaft 1. The rock shaft I3 is provided with a coiled spring I6 which holds the said rock shaft I3 in its normal position. The rock shaft l3 has a collar l1 rigidly held thereto by the set screw I8. Projecting from the said collar I1 is a, pin 19 having a rounded head on its upper end. The lever 20 is pivoted to an upright 2i secured to the upper surface of the bed I. This lever 20 carries a wedge-shaped piece 22 which projects through the bed I and rests normally against the side of the rounded head of the pin l9. An arm 23 is also secured to the upper surface of the bed I and has the buttonholding spring jaws 24 mounted in its outer end. The button is placed between the jaws 24 when the machine is to be operated and when the goods is in position under the jaws 24, the lever 20 is forced down carrying the wedge-shaped piece 22 which causes the pin l9 to turn the collar l1 and consequently the rock shaft l3 against the action of the spring [6 and as the said rock shaft I3 is turned, it carries with it the arm I4 and causes the cam l5, which operates in the groove of the wheel 9, to force the pulley 6 in, causing the lug I0 to strike the arm H and as the said pulley 6 is constantly revolving, it causes the shaft 1 to revolve, which, through the mechanism in the standard 2 and arm 3, reciprocates the needle 5. When the needle has made a predetermined amount of stitches, the rock shaft l3 will be thrown back to its normal position by the spring I6 which causes the cam I5 to throw the pulley 6 away from the arm II and stop the operation of the machine.
In the button-sewing machines in general operation, the mechanism is started by a foot treadle which sometimes is thrown into operation before the operator removes her finger from the button and causes her finger to be caught under the needle. By my present invention, this is made impossible as the hand must be removed from the button in order to operate the hand lever on the upper surface of the bed of the machine to throw the machine into operation.
Having thus described my invention, what I claim is:
The combination of a button-sewing machine having a needle and button-holding jaws, means for reciprocating said needle, a drive shaft, an arm rigidly mounted on said drive shaft, a pulley loosely mounted on said drive shaft adjacent the said arm and having a lug projecting therefrom, a grooved wheel integral with said pulley, a rock shaft, a coiled spring operatively connected to said rock shaft to hold and return it to its normal position, a collar rigidly secured to said rock shaft, a pin projecting from said collar, a lever mounted on the upper surface of the base of said machine adjacent the button-holding jaws, a wedge-shaped piece secured to said lever and projecting through the said base and operative against said pin to rock said rock shaft in opposition to the action of said spring, and an arm on said rock shaft having a cam on its outer end operating in said grooved wheel to throw the pulley into operative connection with the drive shaft to start the machine.
