TUFTlNG-IVIACHINE.

SPECIFICATION forming-part of Letters Patent No. 714,441, dated November 25, 1902.

Application filed November 13, 1899. Serial No. 736,833. (No model) To a/ZZ whom, i may concer-n,.-

Beit known that we, JOHN C. BoRGwARDr and WILLIAM CONSOER, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tufting-Machines; and we do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to a novel construetion in a tufting machine or apparatus, the object being to provide a device of this character which will enable the upholsterer to quickly makea complete Vtufted cushion for couches and other furniture; and it consists elevation of the tufting board or table, show ing another means for fastening the canvas or other fabric stretched over same. isa detail sectional view on the line l0 10 of Fig. 1.` Figs. 7, 8, 9, and lO are fragmentary detail sections showing modified forms of construction of the tufting board or table. Fig. 11 is a fragmentary detail section showing a modified form of devices for bending the button-Shanks. I Fig. 2 is a detail sectional view on the line 16 16 ofFig. 6. Fig. 13 is a detail sectional View of a tufted cushion, showing the button bent and retained by the retaining-plate. Fig. 14 is a detail sectional view on the line 18 18 ofFig. l.

top planview of-a `modified form ofguidepiece to be mounted on `the sides of the tufting-board to receive the side retaining-plates. Fig. 16 is a section of same on the line 20 20 of Fig. 15.`

One feature of our invention consists in providing a tufting-machine wherein all the Fig. 2`

Fig. 15 is a steps off making a completed cushion are manually performed.

Another feature of our invention consists in providing suitable devices at the orifices of said openings to hold in place over same 4 y buttons 3 are generally used in combination with retaining plates or Washers 12 on the under side of the cushion, said openings 11 are preferably surrounded at their oriiices with suitable devices for holding said retaining plates in place over same. Said devices consist, preferably, of an annular countersink 13, surrounding the orifice of each opening and adapted to receive said retaining-plates 12. Said devices may,\however, consist of an annular shoulder 14, as shown in Fig. 9, surrounding each of said openings 11 and adapted to enter the concave portion of the plate, and thereby hold same in place. Other devices of a similar nature could obviously be used; but we desire it to be understood that any means for holding said retaining-plates in place falls within the scope of our invention. "Said board 10 is preferably sufliciently thin-to permit the button-shank to project below same after passing through the retaining-plate and material above same, so that it can be readily bent by any suitable means. The said board 10 is preferably mounted parallel with and above another board-15, which is covered over its entire surface or at points below the openings 11 with sheet metal o r a similar hard material 16, which is impervious to the point of the button-shank, so that when the latter strikes such hard surface and is pressed down upon the same it will be caused to bend, the bending-point' being predeter- ICO` mined by weakening the shank at a given point in the class of upholsterers buttons preferably used in connection with our device. In this class of buttons the length of the shank below the bending-point is greater than the radius of the openings 11, so that it is necessary to provide a space of sufficient radius below the openings 11 to permit said end of said shank to enter freely. This may be accomplished by providing an intervening space 17 between the boards 10 and 15, as shown in Figs. 3, 6, 7, and 9, or by countersinking or enlarging the lower orifice of the openings 11, 'as shown in Figs. 8 and 10. In the last-named figures we have shown the metal plate 16 secured directly to the lower face of the board 10, which obviously performs the same function as when mounted upon the board 15. Where the intervening space 17 is employed, the same is formed by inserting cross-pieces 18 between the two boards 10 and 15 or in any other manner raising the board 10 out of contact with the board 15 or its covering 16. Instead ot' said sheet-metal covering 16 small circular plates 18L may be secured to the board 15 below said openings 11 in any1 suitable manner, as shown in Fig. 7, the upper faces of said plates being concave to cause the button-Shanks to bend more sharply than where a plane surface is used, as will be obvious. Other means for bending said button-Shanks may also be employed-as, for instance, the device shown in Fig. 11, which consists of a plurality of parallel plates 19, pivotally secured to the lower face of the board l0 and depending therefrom, each of said plat-es passing underneath a line of said openings 11 to one side of the centers thereof and all pivotally connected to a cross bar or rod 20, by means of which said plates may be swung to the position indicated in dotted lines, thereby bending over any shank lying in their respective paths, or said plates 19 may also be omitted and the shanks bent by hand, if so desired. Said board is provided with side rails 21, provided with recesses 22, which open at the top and outer faces of said side rails. Adjacent said recesses 22 we provide suitable vertical guides 23 for receiving and holding retaining-plates in front of same. The said guides may be formed by securing plates 24 to the outer faces of said side rails 2l between each two recesses 22 and of a width to enti rely cover the intervening space,the edges of said plates being bent slightly outwardly adjacent said recesses 22, thereby leaving small spaces between said plates and the adjacent face of the side rail, thus forming said guides. The innermost sides of said recesses 22 are also lined with sheet metal or similar hard material which will cause a button-shank to bend when forced against the same. Another convenient method for securing the same result consists in fitting into each recess 23 a casting 25, (shown in Figs. 6 and 12,) said casting having four Walls, of which the two vertical side walls are provided on their inner faces with guide-grooves 26 to receive the retaining-plates. The same result will be accomplished by the construction shown in Figs. 15 and 16, where each recess in the side rails is provided with a back-plate 42, having a dish-shaped recess 43 to receive the washer, which is slipped in through the open top thereof and held in position by a faceplate 44, having a central portion 45 to permit the passage of the button, but of less diameter than the recess 43 to form retainingshoulders 46, the bottom of the receptacle thus formed preferably being inwardly beveled, as shown in Fig. 16. Thesaid side rails 21 may be made adjustable, as shown in Fig. 14, to accommodate various widths of cushions. Said board 10 is provided, preferably, with rigid end rails 27, provided at their ends with openings 28 to receive the ends of setscrews 29, a nut 30 being introduced through transverse recesses 31 and extending transversely in said openings 28 to engage said setscrews. The latter are provided with collars 32 adjacent their outer ends, which enter enlargements 33 of the openings 34 and are held in place therein by means of pins 35, intersecting said enlargements 33 of said openings 34. 'lhe outer ends of said screws 29 are provided with pivoted heads 36, which may be turned to lie against the outer faces of the side rails after the latter have been adjusted. When said tufting-table is designed for upholstering couch-tops in which a head- IOO rest is formed, the said board is provided between its ends with a transverse groove 37, which terminates at the side rails 21, the latter being provided in alinementl with and adjacent the bottom of said transverse groove with openings to permit the passage of a rod 38 therethrough and spanning said groove. The said groove 37 is adapted to recess a certain portion of the fabric forming the base of the cushion and forming the division between the body portion and head-rest portion of the cushion.

In using our tufting-board the operator first places his retaining plates or washers 12 in place over the openings 11 when it is desired to use Washers, then lays his fabric B, which is to form the base of his cushion, over the board in proper position. If the cushion is designed to havea body and head-rest portion, he first depresses a fold of his base fabric or backing into said groove 37 and cuts slits in the ends of the fold to permit the rod 38 to pass therethrough. After passing said rod 38 through to prevent withdrawal of the slackf as such fold is termed, he stretches the base fabric over the entire board to secure a smooth plane surface, the said fabric being secured either by pins passing through the depending portions and into openings 39 in said side and end rails, or preferably he forces said fabric over the ends of pins 40, projecting downwardly from the lower faces of said side and end rails, as shown in Figs. 5 and 6. The latter means of fastening is IIO simpler and more efficient. I-Ie then lays his passes a given line of the shanks of the butl introduced in the proper manner to form the raised tufts in the cushion. Then the second line of button-Shanks is passedthrough the corresponding line of retaining-plates, and so on until the cushioniscompleted. Af-

`ter the top tufts or body-tufts are finished the operator forms the side tufts, `first plaiting the cover to take up the slack corresponding `to the fullness of the body-tufts and then` piercing it at the proper points by inserting i a button-shank through the plait, passing thel shank through its corresponding side retain-` ing plate or washer l2. `The successive stepsf in the formation of the cushion are illustrated in Fig. l, which shows at the right-hand side,

first, the apertures or openings ll in the board or table before the washers are in place;y second, the apertures after the washers 12 are inserted in their seats; third,aportion of the backing or base fabric B stretched over the washers in their seats; fourth, the` fastening-rod employed to form the slack in` the bottom fabric or backing to permit of the elevation or tilting of the head-rest section of the pad; fifth, .a section of the top cover showing the button shanks or prongs inserted therer Same'.

through, and, sixth, a `portion of the `completed cushion,showing the formation of the tufts. After thus completing the cushion the base fabric is released, the rod 38 withdrawn,

and the cushion removed.

By means of our device any unskilled person can after a weeks practice compete with the most expert upholsterer in the production of tufted cushions.
