QUILTING-MACHINE.

Specification of Letters Patent.

Patented Mar. 5, 1912.

Application filed May 16, 1301. Serial No. 60,529.

To all whom it may concern:

Be it known that I, Onnnu. Asn'rox, a

.citizen of the United States, residing at support having a throat through which a feeding device operates, said feeding device engaging the work lying on said work support and feeding the work for the dlstance desired between adjacentfastenings. The work support and the feeding device, herein represented as a wheel, are yieldingly sustained that they may rise and fall together to enable the machine to act on stock of any thickness. The work support is represented as attached to the upper end of a rod normally sustained by a spring which exerts sufficient tension to support the material, but not enough to interfere with the feeding of the stock. The rod sustaining the work support has combined with it auxilliary pressure means including a stronger spring and a lever which, just prior to each action of the driver and the insertion of a fastening, acts through the stronger spring to sustain the work support substantially rigidly while the fastening is being inserted. In case it should be desired to do what vis called monogram quilting, the automatic feeding of the stock is preferably suspended by temporarily closing the feed opening of the work support, and at this time a nut on the rod sustaining the work support is adjusted into such position that it may be struck at each operation of the machine by a device such, for example, as a lever which partially releases the stock leaving it free to be moved by hand between the insertion of successive fastenings.

Figure 1 in elevation represents a part of the right hand side of a machine embodying my invention. Fig. 1 is a detail showing the feed wheel in section and applied to the feed actuating shaft. Fig. 2 is a similar view of the lower part of the machine represented in Fig. 1, Figs. 1 and 2 together making a complete right hand side elevation. Fig. 3 is a detail looking at Fig. 2 from the left, said figure showing the treadles. Fig. 4 is a detail looking at the part of the machine shown in Fig. 2 from the right hand side. Fig. 5 is a front view looking at the machine shown in Fig. 1 from the left. Fig. 6 is a rear view of the machine shown in Fig. 1. Fig. 7 shows the head detached from the neck or frame used to support it. Fig. 8 is a section in the line 50 Fig. 1. Fig. 9 is a section in the line 00 Fig. 8. Fig. 10 shows the face of the work support when a feeding device is to be used. Fig. 11 shows the cover for the work support employed in monogram work.

Referring to the drawings, A represents a column to stand on the floor, and A a neck secured to the column and provided with bearings for the different operative parts of the machine to be described. The neck presents an overhanging arm A and an extended tubular arm A The arm A is provided at its front end with ears A which constitute a seat for the head A, shown detached in Fig. 7, said head constituting a guide for a driver bar a provided at its lower end with a driver a and at its upper end with a block a free to be slid between vertical walls a of said head, said block receiving a screw stud a carried by a link a, said stud receiving upon its outside said block a nut a The linka is connected at its lower end to a crank pin a of a disk (6 attached to the shaft A the rotation of which shaft actuates the driver bar positively in both directions.

The machine herein illustrated has two wheels 2, f to feed a wire through a guideway, f which wire is cut off at proper times for the formation of fastenings, the fastenings being thereafter placed in line with the driver to be driven into the stock.

The head A has a boss n,see'Fig.7, which receives, see dotted lines Fig. 1, and in section in Fig. 8, a rocking stud n having at its outer end a pawl carrier a and to which is connected a pawl 11 adapted to engage a ratchet .fflfimd to the feed-wheel 2. At its inner end said stud has an arm 02 provided with a suitable rolleror other stud n which is normally kept pressed by a suitable spring 11, toward a cam 71 carried by the shaft A The rocker arm n is provided with a feed regulator 11, shown in Fig. 8 as a screw which is adjust-able to contact sooner or later with the shoulder a forming part of the arm A to limit the extent of movement of the wire feeding mechanism.

The neck contains a bearing 9 pivoted at p for a shaft 2 herein represented as provided at its forward end with a stock feed ing device shown as a wheel 79 presenting two sets of teeth p with a groove 32* between them, see Fig. 1 the object of the groove being to receive the point of each fastening as the same is driven if the length of the fastening should exceed the thickness of the stock, or in case one fastening should be driven on another. The shaft 79 is sustained at its forward end back of said feed wheel in a movable bearing 7), see Figs. 1 and 8, said bearing having flat sides and being fitted to slide up and down and also longitudinally of a guideway 39 formed in the tubular arm A This bearing has extended from its end a curved flange 30 forming part of a case to be described, the other part of the case, see Fig. 5, being marked 2 and being connected with the portion 30 by screws 31. The upper portion p of the case constitutes a work support, said portion being slotted at its upper side, see Fig. 10, to enable the teeth of the feed wheel p to project therethrough to engage the stock and feed the same over the work support. The portion ,1) has a hole 30 through which the driver may be inserted or withdrawn as will bedescribed. The inner end of the bearing 10' surrounds a reduced part of the shaft p and abuts a shoulder of said shaft, see dotted lines Fig. 1. Just beyond the outer end of the bearing 79* the shaft is again reduced, see Fig. 1*, at y) and threaded, and the feed wheel 39 is screwed onto the threaded end of the shaft. The outer hub of the feed wheel is faced or made hexagonal, as rep resented in Fig. 5, that it may be engaged by a wrench or other device by which to screw the feed wheel firmly onto the shaft, and said hub is provided with a hole 79 Normally the hole 30* in the part 79 of the case and the hole p in the hub of the feed wheel occupy a position at one side of the line of movement of the driver, but whenever it is desired to remove the driver from the driver bar or to insert a driver in said driver bar, the workman will slide the bearing 79 to the right, viewing Fig. 1, taking with it the shaft, the feed wheel, and the work support, thus placing the holes 30* and 72 vertically in line with the driver, and thereafter the driver may be disconnected from the driver bar and drawn out through said holes. To provide for moving the bearing p and the shaft 1) as stated,

-said bearing is provided at one side with a groove Z03, in which is mounted a loose block w, see Fig. 8, having a hole that is entered by an eccentric stud 10 at the end of a rotating shaft w. Said shaft w has two flat surfaces w, see Fig. 9, which are adapted to be engaged by a plunger 10, yieldingly sustained by a spring w supported on an adjusting screw 40. The shaft 10 has a handle 10 for imparting a rotary movement thereto when it is desired to move the bearing 72* and is also provided with an annular groove that is entered by a washer w which holds the shaft in place, said washer being. held in position by a screw w, as shown in Fig. 9.

The bearing 72* in which the work support is sustained receives the threaded end of a rod 9, see Figs. 1, 2 and 5, extended loosely through an enlarged hole in a part 79 proj ecting from the column A. The rod 10 has applied to it below the projecting part 22 a collar which is held in adjusted position thereon by a clamp screw [9 the adjustment of said collar limiting the upward movement of the work support and feed wheel toward the foot plate 0 to thus prevent the contact of the points of the feed wheel with the underside of said foot plate. The rod 7) has screwed upon it a second adjust-able collar 79 which is retained in adjusted position by a set screw p The upper end of a spring 72 sustained by a washer 79 resting upon a slotted ear [9 extended from the column A. acts on the underside of the collar p and serves normally to keep the work support and the feed device pressed upwardly with sufiicient tension to enable said feed device to engage the stock with a force sufficient to move it over the work support and between said work support and the underside of the foot plate when the feed device is rotated. The rod 7) has clamped upon it below the ear 7)" a third collar 79 said collar being adjustable on said rod by means of a screw 2 The collar 72 is acted upon at its lower side by a strong spring p the lower end of which, see Fig. 2, rests on a collar 12 having a dependent lug p which enters a notch between two ears 11 at the end of a lever 79 pivoted on a stud p sustained in the column A, said collar having depressions 42 which are entered by the rounded portions of said ears 411. Said lever has jointed to it at its opposite end a link 39 which is extended upwardly, see Figs. 1 and 2, and connected with a stud 79 of a rocking arm 72* mounted upon a stud 79 see Figs. 1 and 6, said arm having extended from it a stud p which is embraced loosely by the lower end of a link 79 having at its upper end a strap 79 surrounding an eccentric 39 see dotted lines Fig. .6 fast on the shaft A said eccentric through the means described imparting to the lever 72 a continuous uniform stroke throughout the operation of the machine. The operation of the eccentric p is so timed as to raise the outer end of the lever 10, that it, acting through the collar 10 and spring 72 may put additional pressure on the work support just as and while a fastening is being driven into the work, at which time the work should be clamped. \Vhen the machine is stopped, the eccentric occupies a-position to place the outer end of lever p in its lowest position, at which time only the spring p acts to lift the rod 11 and work-support, and at this time the operator to depress the work-support for the removal or insertion of work has only to overcome the pressure of the single, spring The lower end of rod 19 is jointed by a screw 12 see Figs. 2 and 3, with a foot treadle p .fulcrumed on a long stud 79, mounted in a bearing 19 connected with the foot of the column, the outer end of said lever having a right angled project-ion 100, see Figs. 2 and 3, the depression of the free end of said treadle lowering the work support and feeding device whenever it is desired to remove and apply stock. A yokeshaped foot treadle 7" is also mounted upon stud 29 said foot treadle having an extended arm 1" to which is connected a spiral'spring T the opposite end of said spring being connected with a projection r extended from the column, another arm r of said treadle,

see Fig. at, having jointed to it at 1' the lower end of a rod 7. The upper end of the rod 9 carries a wedge block 0" which controls in usual manner the engagement and disengagement of the clutch pulleys r and 1 to stop or start the shaft A which carries a pulley 1" that is driven bythe belt 7' surrounding pulley T The shaft 792 is provided with a ratchet wheel I, which is engaged and moved step by step by a pawl t preferably adjustably mounted, see Fig. 6, in the end of arm t eccentrically connected by a screw t with the end of the shaft A said pawl being reciprocated during each rotation of said shaft. This pawl t is connected with the arm 25 by a suitable set screw W, a suitable detent 6 controlled by a'spring 25 acting to prevent retrograde movement of said shaft and its feed wheel.

In the operation of the machine described the stock or work is fed over the work support by the feed wheel, while the front end of the lever 72 is depressed or occupies a position to relieve the spring 79 from the pressure of said lever, said spring acting it will be understood on the collar 79, and.

while the stock is being fed only the lighter spring 0 exerts pressure just sufiicient to enable the feeding device to properly engage and move the work or stock over the work support. Then a fastening is being inserted the work support needs to be held up more firmly to resist the thrust of the driver, and at such time the lever is moved to act on the collar 79 and compress the strong spring I prefer to employ a rotatable feed wheel for feeding the stock, yet it will be understood that my invention would not be departed from should I substitute for said feed wheel any other well known equivalent feeding device.

In case it is desired to quilt a monogram, for which work the movement of the stock is so varied that it could not be well handled by the feeding device working automatically, I intend to remove the part 29 of the case and substitute for it a cover plate a, see Fig. 11, of the same shape but without the feed opening shown in the plate of Fig. 10. This cover presents a smooth surface upon which the under face of the stock rests, and the feed device is prevented from engagement with the stock. When the action of the feeding device is to be suspended for monogram work, I rotate the collar 66, see Fig. 2, on the threaded part of the rod 72 below the lever 79 and raise said collar on said rod, putting the collar in such position that the left hand end of the lever 72 in the last part of each downward stroke will meet said collar and act automatically to depress the rod 39 and the work support sufficiently to release the work that the operator holding the same in his hand may move the workfreely in any direction.
