SPECIFICATION forming part of Letters Patent No. 751,056, dated February 2, 1904.

Application filed April 26, 1902. Serial No- A,807. (No model.)

To all whom it may concern:

Be it known that we, ERNEST H. COOPER and CONRAD ScHfirz, residents of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have jointly invented certain Improvements in Sewing-Machines, of which the following is a specification.

This invention is an improved sewing-machine having a peculiar universal feeding mechanism in combination, with stitching mechanism adapted for plain sewing, embroidering, braiding, and rufliing.

The nature and characteristic features of the improvements will more fully appear by reference to the accompanying drawings, of which Figure l is a front elevation of a sewingmachine embodying our invention. Fig. 2 is an end elevation thereof. Fig. 3 is a rear elevation thereof. Fig. A is a sectional view taken on the line A A of Fig. 2. Fig. 5 is a sectional view taken on the line 5 5 of Fig. A. Fig. 6 is a sectional view taken on the line6 6 of Fig. A. Fig. 7 is a sectional view taken on the line '7 7 of Fig. A. Fig. 8 is a view in illustration of details of the feeding mechanism. Fig. 9 is a view of detached shafts for driving the feeding mechanism. Fig. 10 is a perspective view of the ruflling mechanism detached, and Fig. 11 is a perspective view of the product.

As illustrated in the drawings, a sewingmachine head 1 of usual character has the revoluble main shaft 2, provided with a gearwheel 3, which engages with a gear-wheel A, fixed on a revoluble shaft 5, having the

cams

6 and 7 fixed thereon. The cam 6 engages the stud 8 of the vertically-reciprocating bar 9, which has the ring or bearing 10 and the arm 11, with the depending finger 12 fixed thereon. The cam 7 engages the stud 13 of the vertically-reciprocating bar 1A, which has the yoke or bearing 15 fixed thereon. The finger 12 connects the arm 11 with the bar 1A, reciprocating in the way 16, and a spring 17, having its lower end connected with this bar and its upper end connected with the arm, tends to simultaneously elevate the bar 8 and depress the bar 1A.

The yoke 15 provides a bearing in which the sleeve 18 revolves and by which it is elevated, the sleeve 18 reciprocating on a revoluble sleeve 19, which revolves the sleeve 18 by means of the feather 20. The sleeve or shaft 19, having the gear-wheel 22 fixed thereon, is revolubly mounted ona stem 21, which is carried by the head 1. The gear-wheel 22 is driven by a gear-wheel 23, fixed on the journaled shaft 2A, which is revolved by the bevelgear 25, fixed thereto. The bevel-gear 25 is driven by the bevel-gear 26, fixed on the journaled shaft 27, which is revolved by the bevelgear 28, fixed thereto. The bevel-gear 28 is driven by the bevel gear 29, fixed on the journaled shaft 30, which is revolved by the bevel-gear 31, fixed thereto. The bevel-gear 31 is driven by the bevel-gear 32, fixed on the journaled shaft 33, having the bevel-gear 3A fixed thereon, the latter being driven by the bevel-gear 35 on the journaled shaft 36, which is revolved by the crank 37 The sleeve 18 is provided with the base 18, having the Ways 18", in which guides 38 on the shank-head 39 reciprocate to reciprocate the shank A0 and the foot A1 joined thereto. The reciprocation is effected in outward movement by the downward movement of the rod 9 and the action of the ring 10 upon the rollers A2 on the long arms of the crank-levers A3, fulcrumed on the bearings AA, which are carried by the sleeve 18, the depression of the long arms of the levers causing their short arms, which rest against the bearing-pins A5 of the shank, to thrust the foot mechanism outward from the axis about which it revolves, and the inward movement is effected by means of a stud A6, passed through the shank-head 39 into the base 18, and the coiled spring A7, which is supported by the stud and exerts an inward thrust upon the head. The movement of the foot may be regulated by adjustment of the screw A8, which runs in the shank A0 and is swiveled in the hanger A9 of the slide-bars 50. The bars abut against the base 18 in inward movement and have a limited movement in relation to the head 39 by means of the slots 51, formed therein, and the screws 52, which pass therethrough and engage the bars 50.

The foot 41 comprises the bearing-ring 52 and the feeding-ring or feeder 53, revolubly supported thereby. The feeding-ring preferably telescopes with the bearing-ring and is held thereto by means of the complementary grooves 52 and 53, which are formed in the respective rings, so as to register and receive the balls 54, the latter being passed into the channel through the socket 55, normally closed by the screw 55. This construction permits the feeding mechanism to turn while the feeding-ring engages with and moves the work straight to the needle, radially to the curve of which the needle is the center, by which a universal feeding movement is obtained without twisting the work.

The stitching mechanism may be of usual construction, if desired, comprising the needle-bar 56, connected by the pitman 57 with the main-shaft crank 58. The needle 59, passing through the throat-plate 60, cooperates with the hook 61, which is revolved by the shaft 62, having the pitman connection 63 with the main shaft 2; but the needle-bar has a passage 64 therethrough, bymeans of which and the

openings

65 and 66 thread is passed to the needle clear of the feeding mechanism.

The mechanism described, as will be understood, is adapted for plain sewing, embroidering, and braiding. For braiding and rufliing the spool-carrier 64 is fixed to the base 19, revoluble with the sleeve 19 on the supporting-stem 21, the spool 65, journaled in the carrier, delivering the braid or ribbon 66 to the feeding mechanism. The braid or ribbon feeding mechanism comprises the guide 67, having a pivot bearing-point 68, upon which the guide freely turns about the needle in the operation of feeding the braid thereto from whatever direction required. The guide is carried by the hanger 69, which is provided with a head 70, rigidly secured to the revoluble sleeve-base 19. In plain braiding this guiding mechanism delivers the braid without crimping to the feeder and needle. In rufiling the finger 71 is caused to reciprocate in the guides 67 by means of a lever 72, fulcrumed on the pin 73, the fingerbeing pivotally connected to the lever by the pintle 74 and held in flexible relation to the work by the coiled spring 75, one end of which bears upon the finger, while the other engages the hanger. The lever 72 has the slot 7 2, in which the pintle 76 is adjustably held, and the pitman 77, having one end pivotally connected to the pintle and the other end pivotally connected to the reciprocating bar 78, actuates the finger 71, crimping the braid, as determined by the regulation of the pintle 76. The bar 78 reciprocates in ways 79, carried by the hanger 69, the bar being depressed by the downward thrust of the ring 10 on the roller 80 and being elevated by the coiled spring 81, having one end fixed to the hanger 69 and the other end to the bar. This mechanism is adapted for universal feeding and simultaneously fluting or crimping the braid in the operation of making the ruffiing 82.

It will now be understood that the main shaft 2, operating through the gears 3 and 4, drives the shaft 5 and the

cams

6 and 7, the latter being so connected with the respective rods or bars 9 and 14 that the sleeve 18, with the feeding mechanism connected therewith, first carry the feeder 53 downward into engagement with the work, upon which the ring 10 descends to rock the levers 43 and move the shank 40, with its its connections, outward, causing the feeder to advance the work to the descending needle 59. As the needle descends through the work the sleeve 18 and the feeding mechanism connected therewith are elevated, the spring 47 simultaneously moving the shank 40, with its connections, inward and again descend into engagement with the work as the needle rises and the ring 10 completes its upward movement. Simultaneously with this operation of feeding by revolving the crank 37 the dependent transmitting mechanism operating through the gears 23 and 22 revolves the sleeve 19 and the sleeve 18, with the feeding mechanism connected therewith, so that the radial action of the foot 41 may be varied at will and the work fed to the needle from any desired direction without twisting, as the shank 40 turns independently of the feeder 53. The braid guiding and ruffiing mechanism revolving with the feeding mechanism delivers the ribbon or braid in the direction that the feeder is carrying the work. The downward movement of the ring 10 thrusts down the bar 78 and the pitman 77 rocks the lever 72 and advances the finger 71, which advances the braid and crimps it, as determined by the position of the pintle 7 6. As the ring 10 rises the

springs

75 and 81 restore the finger 71 and the bar 78 to their initial positions.
