To all wwm it may concern.

Be it known that I, ROY L. KnNroN, a citizen. of the United States, residing at lVaukesha, in the county of Waukesha and State of Wisconsin, have invented certain new and useful Improvements in 'Fufting- Machines, of which the following is a specication, reference being had to \the accompanying drawing, forming a part thereof.

rlhis invention relates to means for tufting cushions and the like with buttons and wire.

ts main objects are to facilitate the process of tufting such articles and to improve the product.

It consists in the construction, arrangement and combination of parts as hereinafter particularly described and defined in the claims.

ln the accompanying drawing like characters designate the same parts inthe several figures.

Figure l is a vertical section from front to rear of a machine embodying the invention; Fig. 2 is an enlarged transverse'vertical section on the line 2 2, Fig. l, showing the needle plunger or support withdrawn into normal position andthe needle with a wire and button placed thereon, ready for insertion in a cushion or the like; Fig. 3 is a plan view of that portion of the machine shown in Fig. 2; Fig. 4 is a section similar to Fig. 2, showing the plunger thrust upward, the presser foot lowered and the needle removed; Figs. 5 and '6 are enlarged detail views in perspective showing the preferred formof looped tufting wire used in the machine and the manner of connecting the buttons therewith, and Fig. 7 is an enlarged detail view of the needle.

The machine comprises generally two opposing compressing members, one-of which i is movable toward and from theother and is formed with a central openingin alinement with a similar opening in theother;

l a detached tubular needle for holding a tufting wire connectedfwith a button; a

needle support or plunger yfor thrusting the needle with a tufting wire through a cushion or other article held between `the compressing members, and means for guiding or holding the needle in place on the needle plunger or support.

Referring to the drawing, and more par# ticularly to Fig. 1, a is a rounded projectionor block constituting one of the comu pressing members formed or mounted on a 4 work suporting leaf or table l), which is carried by brackets c extending forwardly end of a reciprocative bar or Vslide it, which is guided in a vertical sleeve on an overhanging arm of the standard or frame d.

Below the leaf or table b and in alinement with the central openings in the compressing members a and e, av reciprocative needle plunger or support y' is guided in ja vertical sleeve of a bracket is attached to the under side of said leaf or table, as shown in Figs. 2 and 4. The upper end of the plunger or support j is enlarged `and formedv with a cavity or seat to receive and hold a tufting button.

l designates a detached or removable needle solid and pointed at one end having a tubular or hollow shank open at the opposite end and transversely notched or slotted through its open end, as shownin Fig. 7 to receive a looped tufting wire m, and the eye loop of a tufting button n with which the looped wire is engaged at one end, as shown in Fig. 2. v

The needle is held in place and guided in operative relation tothe plunger or support j and other parts of the machine, as shown in Fig. 2, by jaws or gu1des 0, movable laterally toward and from the path of the plunger or support y' in bearings p on the under side of the leaf or table b. rlhe jaws are beveled or inclined outwardly at the top and bottom to permit the enlarged upper end of the needle plunger or support j to force them apart and pass between them both upwardly and downwardly. They are pressed toward each other and yieldingly held against opposite sides of the needle Zhor of the plunger or support j by rocker` arms g which are pivoted at their lower ends to thebracket k and engagedV at their upper ends with the outwardly extended shanks of the jaws and by springs r connecting said rocker arms with projections on said bracket.

For separating the jaws o to receive the needle Z between them, one of the rocker arms g is formed or provided at its lowei end with an extension s, and a rocker shaft Z parallel with the pivot of said rocker arm is provided with an arm a in position to engage with the extension s and at its front end with a crank handle o, as shown in Figs.l l, 2 and al..

By turning the handle fv to the left or toward the needle support or plunger y' the upper end of the adjacent arm l is rocked to the right and the jaw 0. connected therewith is withdrawn from the other jaw so that the needle can be placed in position between them. The outer ends of the bearings 29 serve as stops by engagement with the arms q, to limit the inward movement of the jaws o by the springs r, as shown by Fig. 2.

For operating the presser foot or movable compressing member e and the needle plunger or support j, the following provision is made:

A treadle or foot lever 'w fulcrumed in a stand .fr on the base of the frame CZ, is connected at its rear end by a rod jz/ with the rear arm of a lever a, which is fulcrumed to the overhanging arm of said frame and is connected at its front end with the bar or slide h. Adjacent to its front end thetreadle or lever 'LU is connected by a rod 2 with the rear end of a lever 3, which is fulcrumed to a bracket 4 on the standard or frame Z and connected by a link 5 with the lower end of the needle plunger or support y'. A spring 6 connecting the rear arm of the treadle or lever w with the frame base, tends to withdraw the bar or slide h. to its upper position said treadle or lever wall not move the needle plunger or support until the presser foot or compressing member c has descended upon a cushion or other article and pressed the same firmly against the opposing member a.

In the operation of the machine, the needle Z, furnished with a wire to which a button is attached, is placed between the jaws o with the button resting in the cavity in the upper end of the plunger or support y', as shown in Figs. l, 2 and 3, one of the jaws o being withdrawn by turning the crank handle o inward to receive the needle, as hereinbefore explained. A cushion or other article to be tufted is then placed on the leaf or table b between the opposing compressing members a and e in proper position for the insertion of the wire and setting of the but- Lamas? tons connected therewith.' The treadle or foot lever w is now depressed and operates j 'first to move the presser foot or compressing drawn by the operator, leaving `the upper j looped end of the wire' fm, protruding and eX- posed in said opening. The eye loop of a button is engaged with the loop of the wire and t-he treadle being released, the presser foot e and the plunger y' are withdrawn and returned to their original positions, as shown in Fig. l, bythe spring 6. The needle is directed in proper position into and guided through or partially through the cushion or other article by the jaws 0, which yield outwardly when the enlarged upper end of the plunger j in moving both upward and downward, engages the bevels or inclines on the lower and upper sides of the jaws. The cushion or other article is then moved into another position and the operations above mentioned are repeated until it is completely tufted.

Double looped wires m', formed as shown in Figs. 5 and G, are preferably used in the machine, these wires being each supplied with a single button '/1, and inserted in theneedle Z with their double looped ends foremost. After the wire is inserted in a cushion or other article, as shown in Fig. 4, and the needle withdrawn, the eye loop of a button is crowded between the two upper loops around one of them, as shown by Fig. 5, and then` after passing the free ends of the loops, drawn back upwardly into engagement with both, as shown in Fig. 6. This form of wire makes a Very strong and durable fastening.

For tufting cushions or other articles of different thicknesses, the presser foot or upper compressing member e is adjusted up or down as required, in the bar or slide h, and the rod y is connected with one of the several holes in the rear arm of lever z to produce the desired traverse or movement of the presser foot.

For diiierent kinds of work, compressing members a and e of different shapes and sizes may be provided, these members being easily removed and replaced in the machine.

Various changes in details of construction and arrangement of parts may be made without materially affecting the principle and operation of the machine and without departing from the scope of the invention.
