PRESSER-FOOT-LIFTING MECHANISM FOR SEWING-MACHINES.
Specification of Letters Patent.
Patented April 23, 1907.
Application filed January 13. 1905. Serial No. 240,929.
To rbZl whom it may concern.-
Be it known that I, JOSEPH M. MEnRow, a citizen of the United States, residing in the city of Hartford, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Presser-Foot-Lifting Mechanisms for Sewing-Machines; and I do hereby declare the following to be a full,
clear, and exact description of the same, refe1 ence being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.
This invention relates to mechanism for the manipulation of the presser feet of sewing machines, both by hand and in other ways, as for instance, by the operators foot, and the object of the invention is to generally improve such devices.
Mechanism of the kind referred to as heretofore constructed has, in so far as I am aware, contained hand operated mechanism and companion mechanism (usually foot operated) that have been practically distinct from each other, the sewing machine having virtually two presser foot lifting mechanisms.
In contradistinction to the construction just recited the invention herein described provides presser foot lifting mechanism,
0 containing elements common to both the hand and the companion (hereinafter referred to as the foot Operated) mechanisms, a foot operated lifter being provided, one or more of the elements of which may be utilized inde- 3 5 pendently to raise the presser foot by hand.
The accompanying drawings illustrate this invention as follows:
Figure 1 is an elevation of the presser foot lifting device and shows further, in outline,
0 a sewing machine in connection with which it is used. Fig. 2 is a plan view of the presser foot lifting device on a somewhat enlarged scale. Fig. 3 is a combined elevation and sectional view of the upper portion of the device, the portion in section being taken on the line 3 3 of Fig. 2. Fig. 4 is a view, simi lar to the Fig. 3, the sectional portion thereof being taken on the line 4*4 of Fig. 2. Fig. 5 is an elevation of a portion of the mechan 5o ism of the Fig. 2 as viewed from the left of the said Fig. 2.
In the drawings like reference figures and letters denote the same parts throughout the several views.
1. is the stand or table upon which the presser-foot lifter is mounted and secured, as is also the sewing machine 2 in connection with which the lifter is used. The sewing machine illustrated in the drawings is of the type commonly known as the Morrow overseaming machine but this invention is as well applicable to other styles of machines.
The numeral 3 denotes a frame or stand on which the operative elements of the lifter are mounted, this stand being provided with ears 3, 3", which support a pin l forming the axial rod or pivotal pin of an element 5 of angle lever form, mounted on the pin between the said ears. Arm 5 of the element 5 is preferably of considerable length and is the operating arm of the element while the other arm 5 is somewhat shorter. The hub of the element 5 is shown as being of considerable length and the arms 5, 5 are located near the opposite ends of the said hub adjacent respectively to the ears 3, 3 of the stand 3. The pin 4 may be held against endwise displacement by a set screw 6 which may be located in the angle lever element 5 as shown.
The hub of the angle lever element 5 is somewhat shorter in length than the distance between the ears 3, 3 that there may be loosely mounted "upon the pin 4, between the last named ear and the adjacent end of the hub, a lever 7 which forms the presser foot lifting lever proper of the device. The lever 7 is adapted to rest on or be engaged by a stud or boss 5 located on the side of the arm 5 near the outer end of the latter.
The lever arm 5' extends over the stand 3, which latter is bored at 3 for a spring pressed plunger 8. One end of the plunger 8 projects from the hole 3", and engages the arm 5 and the opposite end of the said plunger bears against a spring 9 seated in the hole 3 and conlined therein between the end of the plunger and the bottom of the hole, the spring thus operating through the plunger 8 to force the arm 5 upward. Rocking movement the element 5 in the direction last mentioned is limited, however, by the arm 5 which is adapted to engage the stand 3 in the manner best shown in Fig. 4, while rockmay readily be used with certain sewing maing motion in the opposite direction is preferably limited and controlled by an adjustable stop carried by the arm 5 and adapted to engage the stand 3. The said stop is preferably of set screw form and two screws 12, 12 are shown which serve to check each other in the well understood manner.
The number 10 denotes a wire or other suitable connection leading from the free end of the arm 5 to some suitable operating device, as, for example, a foot lever 11 hingerL to the floor in which instance the wire 10 passes through an opening 1 in the. table 1.
The presser foot shank 13 has a projection or stud 13 and carries at its lower end the foot proper 13 Said shank is arranged to slide vertically in the machine head 2 to raise and lower the presser foot in the usual manner.
The presser foot lifting device is so positioned relatively to the sewing machine (usually in the rear of the latter) that the lifting lever 7 lies directly beneath the stud 13 ofthe presser foot shank, the free end of the said lever pointing toward the operator and constituting a convenient finger piece. Should it be desired to lift the presser foot by hand the free end of the lever 7 is swung upward on the pin I in the usual way to engage the stud 13 and raise the presser foot as shown by the dotted lines in Fig. 3. Should the hands of the operator not be free the presser foot mechanism may be readily actuated by the foot of the operator, the treadle 11 being forced downward and the latter through the wire 10 secured to the arm 5 of the element 5 rocking the latter, as shown in Fig. 4, against the force of the spring 9, Fig. 3. Rocking motion of the element 5 is, through the arm 5 whose stud 5 engages the lever 7, imparted to the said lever and the said lever is rocked as though lifted from its free end, thereby effecting the raising of the presser foot as also clearly shown in dotted lines in Fig. 4.
It will now be seen that presser foot lifting mechanism is provided, having a lever which may be directly operated by the hand of the operator (independently of the balance of the lifter mechanism) to rai e the presser foot, or the said lever may be made to operate in the same manner, though indirectly, through the said balance of the mechanism.
The presser foot lifting device as herein shown and described is of such form that it chines now in common use by suitably attaching this device to the table in the rear of the machine.
It is obvious that devices embodying the invention may be attacheddirectly to the sewing machine, or the parts may be embodied directly in a properly designed ma chine and hence I do not wish to be limited and a connection between the foot treadle and the angle lever whereby the depression of the foot treadle actuates the hand lever to effect the raising of the presser-foot, substantially as described.
2. In combination with a sewing machine presser foot, a combined hand and foot operated mechanism for lifting the presser foot comprising a pivotally secured hand lever for engaging and raising the presser foot, an an gle lever engaging the hand lever and adapted for connection with means whereby it may be rocked, a pivotal support common to both the hand lever and the angle lever, the
said means for rocking the angle lever comprising a spring and a plunger acting normally to hold the angle lever in inoperative position, a foot treadle and a connection between the foot treadle and the angle lever whereby the depression of the foot treadle actuates the hand lever to'effect the raising of the presser foot; substantially as described.
3. A presser foot lifting attachment for sewing machines comprising a detachable stand, a hand lever for raising the presser foot and a second lever for actuating the said hand lever, said levers being both pivoted upon the said stand substantially as described.
4. A presser foot lifting attachment for sewing machines, consisting in a detachable stand av lever for lifting the presser foot by hand, a secondarylever for actuating the said hand lever independently of the hand, both pivoted on the stand, a spring to actuate the secondary lever in one direction and a treadle and a connection between the said treadle IIC and the secondary lever to actuate the latter and the angle lever, the means for rocking i whereby the depression of the treadle actuthe angle lever comprising a spring and at I ates the handliftinglever to cheat theruising plunger in the support, the plunger engaging E of the presser Foot, substantially as described. the angle lever and acting normally to so JOSEPH M.
