UPHOLSTERING APPARATUS..

Specification of Letters Patent.

Patented Feb. 6, 1906.

Application filed June 21, 1905. Serial No. 266,351.

To LZ/ whom '1125 may concern:

Be it known that I, MAURICE TAUBER, a citizen of the United States, residing at Chi cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Upholstering Apparatus, oi which the following is a speciiication.

The obj ect oi' this invention is the production oi an improved. apparatus or machine i'or use in making the upholstered covers oi couches, chairs, and. other articles of 'furniture,

In the accompanying drawings, Figure 1 is a vertical sectional view through an apparatus embodying the features of my invention. Fig. 2 is a detail View showing the counterbalancing means for the needle-tube Al'rame and the needle-frame. Fig. 3 is a detail view oi the means for locking the needle-tube frame in position. Fig. 1 is a 'l'ragmental view oil the supporting-frame of the machine and the work-board. Fig. 5 is a iragmental view oi` the supporting-frame, showing a portion of the presserboard Figs. 6 to 10 are views in a series, illustrating the manner oi' using the apparatus. Fig. 11 is a iraginental detail view showing the means for guiding the platen in its movements.

The general proportions of the apparatus are determined by the size of the upholstered cover to be made upon it, though it will be understood that small covers may be made upon an apparatus especially intended for the formation of larger ones.

In the embodiment oi this invention illustrated in the drawings the supporting-iramcwork of the apparatus comprises a substantially rectangular base 1, rising from the corners of which are the posts 2. The upper ends oi these posts 2 at each end of theiramework are connected together by means of cross-braces 3, and said cross-braces are united by means of a longitudinal brace 4. Brackets 5 are secured to the posts 2 at one side oit the machine, and brackets 6 to the posts upon the opposite side thereof. rIhese brackets are connected by bars 7, extending around the ends and sides of the machine. The brackets k5 each comprise a socket 3, adapted to receive the pivot-pins 9 ci a rectangular work-board 10, which pivot-pins are secured to said board at one edge thereof, the opposite side of said work-board being supported upon a suitable :number of lugs 11,

machine below the work-board 10, said frame comprising sleeves 14, surrounding the posts 2, side bars 15, cross-bars 16, and longitudinal bars 17, said

bars

16 and 17 crossing each other (in this instance) at right angles and at the points oif crossing being provided with openings 13, within which openings are secured upwardly-extending needlc-tubes 19. The needle-tubes 19 are so arranged upon their supporting-'Irame 13 as to be adaptedto pass upwardly through the centers of the openings 12 in the work board 10. The weight o'l the needle-tube 'trame 13 is substantially counter balanced by meansof counterweights 20, which weights are connected to said frame by straps 21, extending over the guide-sheaves 22, said guide-sheaves being rotatably mounted upon the brackets 5 and 6. The needle-tube frame 13 is arranged to be locked in its upper position by means of a locking-plunger 23, slidably mounted in a recess 24 in two oi the sleeves 14. A lockingopening 25 is formed in the posts upon which said sleeves are mounted, within which openings said plungers are adapted to lie. The plunger 23 is provided with an operatingknob 26. A coil-spring 27, lying in the recess 24, tends to move said plunger into engagement with the post 2.

A needle-frame 23, substantially similar 1n construction to the needletube frame 13, is slidably supported upon the posts 2, its lower limit oil movement being determined by stopcollars 29 on said posts, which collars are ar ranged to be locked in position on the posts by means of set-screws 30. The weight oi the need.lei"rame 23 is substantially counterbalanced by means of counterweights 31, sup ported upon straps 32, running over guidesheaves 33. At points in said needle-frame 23 directly beneath the needletubes 19 are secured upwardly-extending needles 34. These needles are somewhat longer than the IOO tubes 19, and when the needle-frame 28 is raised, as shown in Fig. 6, the sharp upper ends of said needles project above the upper ends of the tubes 19. Said tubes are beveled at their upper ends to provide a conical surface, continuing the conical point of the needle.

A presser-board 35 is pivotally mounted in the main frame of the machine by means of two pivot-pins 36 at one side of said presserboard, each of said pins lying loosely within a slot 37, formed in one of the brackets 5. As shown in Fig. 5, this presser-board is in the form of a grid and is provided with presserpins 3S at points arranged when the presserboard is in a horizontal position to be directly above the needle tubes 19. The screwthreaded stems 39 of said presser-pins lie within screw-threaded openings 40 in the presserboard 35, means being thus provided for adjusting the position of said pins. The outer side of the head of each of said presser-pins is slightly concave in order the better to engage the upholstering-buttons, as shown in Fig. 9.

A platen 41 is rotatably mounted upon the lower end of a screw 42, which screw extends through a screw-threaded opening in. a boss 43, formed centrally of the longitudinal brace 4. Two of the corners of the platen 41 are notched, as shown at 44, Fig. 11, and slide in contact with two of the posts 2, the platen being thereby held from rotation. A handwhecl 45 is secured to the upper end of the screw 42 for rotating said screw to raise and lower the platen 41.

In operation, assuming the parts to be in the position indicated in Fig. 1, a piece of burlap or other suitable material intended to form the backing a of the upholstered cover is laid upon the work-board 10 and held in place thereon by means of a frame b, laid upon the edges of said backing. The needle-frame 28 is now raised to force the points of the needles 34 through the backing, said needle-frame in its ascent carrying with it the needle-tube frame 13, and the needle-tubes 19 being thereby also forced through the backing, as shown in Fig. 6. When said needle-tube 13 is fully elevated, the locking-plungers 23 engage the locking-openings 25 in the posts 2 and hold said needle-tube frame in its elevated position. r1he needle-frame 28 is then lowered to its initial position.` Hair, tow, or other suitable stuffing material cis placed upon the backing between the needle-tubes 19, said tubes keeping the openings formed by the needles 34 clear of said stuffing material. The fabric d, to form the face of the upholstered cover, is now placed over the upper ends of the needle-tubes 19, sufficient slackness being provided in the fabric d about each needle-tube to permit said fabric to be tufted,

as will be hereinafter described. A button e of any of the well-known constructions comprising a head f and prongs g, is then forced through the fabric d into each of the needletubes 19. The presser-board 35 is now tilted to bring its presser-pins 3S into engagement with the buttons e, as shown in Fig. 8. The needle-tube frame 13 having been unlocked by withdrawing the plungers 23 from engagement with their locking-openings 25, the platen 41 is lowered into contact with the presser-board 35 and said board pressed down upon the work by means of said platen until the needle-tubes 19 have been forced out of the backing a. The presser-board 35 and the work-board l() are then clamped together by means of a suitable number of clamps 7L, of common construction, and said boards tilted into a substantially vertical position, as shown in Fig. 10, exposing the prongs of the buttons to the view of the operator. fashers i are inserted over said prongs and said prongs clenched down upon the backing fabric a. The work-board and presser-board are returned to their horizontal position, the clamps h removed, the presser-board again raised to a vertical position, and the completed cover lifted from the work-board.

I claim as my invention- 1. An upholstering apparatus comprising means for piercing the backing material, and a movable frame carrying a plurality of tubes adapted to extend through the openings thus formed for keeping said openings clear of the stufling material.

2. An upholstering apparatus comprising means for piercing the backing material, and` means for keeping the openings thus formed clear of the stuffing material, said last-mentioned means comprising movably-supported tubes adapted to extend through said openings.

3.' An upholstering apparatus comprising a supporting-framework, a frame slidably mounted in said framework and carrying a plurality of needles for piercing the backing material, and a second frame, also slidably mounted in said framework, carrying a plurality of tubes through which said needles are adapted to extend, said tubes being adapted to extend through the openings formed by said needles.

4. An upholstering apparatus comprising a perforated work-board for supporting the work, a pluralityv of tubes arranged to be moved4 through the perforations in said workboard and adapted to extend into the materials being operated upon, and a plurality of needles arranged to be moved into and out of said tubes.

5. An upholstering apparatus comprising a perforated work-board for supporting the work, and two independently-movable frames, one of said frames carrying a plurality of tubes adapted to be projected through the openings in said work-board, and the other frame "carrying a plurality of needles each adapted to fit Within one of said tubes.
