This invention relates to an upholstery machine adapted particularly, although not exclusively, for making upholstery for vehicle seat and back cushions.

An object of the invention is to provide a machine capable of producing upholstery units of tufted or pleat-like formation consisting of a foundation sheeting and a cover fabric, together with an interposed layer of padding, in an inexpensive, eicient and improved manner and to eliminate the necessity of forming independent tubes and nested seams and/or seam ridges in the material and then feeding independent and individual strips of padding into those tubes,

Another object of the invention is to provide a machine of the foregoing character having means for gripping the edges of the foundation sheeting to hold it taut while it is being fed through the machine, and separate feeding means for the work positioned above and below the same and engageable with the opposite faces of the work for feeding it through the machine.

A further object is to provide a machine having power driven scoring devices for scoring or marking the padding at predetermined points to permit the placing of the fabric pieces in their proper positions with relation to and for engagement by the sewing mechanism of the machine.

Another object of the invention is to provide a. machine having transversely disposed sewing instrumentalities including vertically reciprocable needles, to which the work is fed and presser feet in front of said needles, together with positively driven rotatable members associated with the presser vfeet to compress the work prior to its engagement with the feet and sewing needles.

Another object of the invention is to provide a machine having superimposed sets of positively driven endless work feeding belts located in the spaces between adjacent needles, and a weighted frame structure associated with thel upper set of belts to apply pressure to the top surface ofthe work through the medium of said upper belts.

A further object of the invention is to provide a machine having a stripper for automatically releasing the foundation sheeting from the taut applying gripping means after the upholstery material issues from the sewing mechanism.

The above and other objects and advantages 'of the invention will appear from the following description and appended claims when considered in connection with the accompanying drawingsj forming a part of this specification wherein like reference charactersI designate Itzorresponding parts in the several views.

Before -explaining in detail the present invention it is to be understood that .the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, Ysince the invention is capable of other embodiments and of be.- ing practiced .or 4carried Vout in various ways. Also it is to be understood that the phraseology or terminology .employed herein is for .the purpose of description and not of limitation, and it is not intended to limit the invention claimed herein beyond the requirements of the prior art.

In accordance with the present invention, the embodiment of the machine herein shown and described comprises a positive means for feeding in superimposed relation the foundation sheeting and the layer of padding in continuous lengths, and for also positively feeding a series of cover pieces laid substantially edge to edge upon the` padding, to a series or battery of transversely disposed sewing mechanisms or instrumentalities. The machine also comprises endless taut applying means for the foundation sheeting which diverge slightly from the entrance end of the machine toward the sewing mechanisms to maintain the foundation sheeting stretched evenly during its travel through the machine. The machine also comprises positively driven scoring devices for marking the padding to ensure the proper placement thereupon of the cover material pieces, and positively driven presser rolls ore-disks to compress the material at the lines of stitching prior to the engagement of the material with the presser feet and associated sewing needles. The top series of belts for feeding the material are associated with a weighted frame to apply pressure to the material between the rows or lines of stitching to ensure positive movement, as a unit, of the three layers of material making up the work pieces. At the eXit end of the machine behind the sewing mechanism there is provided a stripper bar which engages the work and strips or releases the foundation sheeting from the taut applying means.

Referring now particularly to the drawings, the entire organization of the present embodiment of the invention is shown diagrammatically in Figs. 1 and 2. The machine, as shown, comprises a horizontal bed or table I3 mounted upon uprights I4 and suitable frame structure, not shown. Mounted upon the table and spaced thereabove is a platform I5 which extends transversely over the table and provides means for supporting a pile of cover material pieces IS. At the front or entrance end of the machine and adjacent the front end of the table I3 there is provided a somewhat smaller supporting table I1 mounted upon upright supports I8 for supporting a roll of cotton batting or padding material IS mounted upon a removable shaft 2l) which engages uprights 2l extending above the table to maintain the roll in place. A roll of foundation sheeting 22 is supported upon an auxiliary platform 23 positioned beneath the table I'I.

The sewing mechanism and associated instrulnentalities of the machine are located at or adjacent the rear or exit end thereof and, as shown, are mounted upon a cross frame member or bar 24 carried by two metal uprights or standards 25, one at each'side of the machine.

Adjacent the front or entrance end of the machine and near'the front edge of the table I3 there is supported, in any convenient manner, a

positively driven roll or drum 25. A similar roll" ork drum 2? is provided adjacent the rear end of the machine behind and beneath the sewing mechanism. These rolls may be in the form of a series of drums of like diameter which are mounted upon a common shaft and xed thereto to rotate together as a unit with the shaft. A driven shaft 25 is mounted or journalled in theupright frame members 25 adjacent to the roll 21 and carries a series of spaced pulleys or drums 29 which are fixed to the shaft to rotate together as a unit with said shaft. Another driven shaft 30 is mounted beneath the table I3 and adjacent the roll 26.

A series of spaced endless belts 3l is provided. These belts engage the rolls or drums 26 and 21 and are driven thereby. The upper course of each of the belts 3| travels over the top surface of the table i3 and preferably in a groove formed in the table (see Fig. 3), the lower course of the belt travelling below the table I3 and over one of the driven drums 29 and the driven shaft 30. The drums 29 and the shaft 30 together pro- Vide tensioning means for the belts 3| as well as auxiliary driving means for said belts. To prevent lateral shifting of the lower courses of the belts, a pair of guide bars or ngers 32 is provided for each of the belts. These guide fingers are mounted upon a transverse rod or shaft 33, see Figs. 2 and 3.

Adjacent each of the side edges of the table I3 there is provided an endless belt 34 which engages the rolls 25 and 2l, one of the drums 29 and the driven shaft 3B. The upper course of each belt travels over the table I3 and preferably in a groove or depression formed therein.

Referring particularly to Figs. 3 and 5, there is shown in detail one of a pair of endless belts 35 which extends lengthwise of the machine and is provided with two spaced rows of staggered pins or screws 36 having points projecting beyond the outer face of the belt. The belts 35 cooperate with the belts 34 as will be seen later and are driven by pulleys 31 mounted upon a shaft 38 adjacent the front end of the machine and by similar pulleys 39 mounted upon a shaft 40 adjacent the rear end of the machine. The shaft lili is preferably slightly longer than the shaft 38 so that the pulleys 39 mounted thereon will be spaced apart a greater distance than the pulleys 3l' which are mounted upon the shaft 38. Thus the belts 35 and also the belts 34 diverge slightly outwardly from the front or entrance end of the machine at A to the rear or exit end thereof at B, see Fig. l. 'I'he courses of each of the belts 35 pass above and below a preferably channel shaped longitudinally extending frame member 4I, see Figs. 3, 5 and 8. Tensioning means for the belts 35 preferably comprise idler rolls or disks li2 which are mounted upon a transverse shaft 43 and engage the belts between the spaced rows of impaling pins or screws 36 carried by the belts. Tensioning means for the rear end of the belts 35 preferably comprises a xed rod or shaft 44. Thus sufficient tension and pressure are applied to the belts 35 to cause the lower courses thereof to force the pins or screws 36 into the foundation material or sheeting as it issues from the roll 22 and to hold said sheeting transversely taut during its travel through the machine. The base portions or webs of the channel members 6i serve to maintain the lower courses ofthe belts 35 in flat condition. As seen particularly in Fig. 5, the lower belt 34 at each side of the machine provides means into which the prongs or points of the pins orscrews 35 may penetrate after they have pierced the foundation material or sheeting 22 and thus protect the bed of the machine.

Mounted above the bed or table I3 of the machine and extending from a point in advance of the sewing mechanism to a point behind said mechanism is a series of endless belts 46. yThese belts are spaced apart transversely of Vthe machine and are driven at their front ends by a roll or drum 4l and at their rear end by. a knurled surface roll or drum 48 (see Fig. 7) which is mounted upon the shaft 4I] carrying the pulleys. 39 previously referred to.

Referring particularly to Figs. 6, 7 and 8, it willY be seen that a weighted frame structure is interposed between the upper and lower courses of theendless belts. 46. As, shown, this structure may comprise longitudinally spaced wood blocks 510 interposed between top and bottom longitudinally extending wood board-s 5I, the blocks in rear of the needle mounted upon a loose or unsupported cross shaft 52 (see Fig. 7). A heavy metal bar53 extends transversely of the spaced pairs of boards 5l and rests upon the lower boards of the pairs.v It will beV understood that the wood blocks 56 and the boards. 5l are secured together at opposite ends and at intermediate points to provide a unitary frame, the front spacer blocks 50 of which are pivotally mounted upon a fixed cross shaft 54 secured at its opposite ends to vertically adjustable brackets 55 mounted upon a portiono-f the machine frame, see Fig. 4. Thus the weighted frame is, in` effect, a floating unit fixed at its front end and free at its rear end, which applies weight and pressure to the lower courses of the endless belts 46 to hold the material in compressed condition in lines interposed between the sewing instrumentalities. Thus the upper set of belts 46 cooperate with the lower set of belts 3l to grip the work and convey the work pieces to and lirough the sewing mechanism and prevent any relative movement of the three laminations forming each of the work pieces, thereby ensuring even stitching through the several layers of material in predetermined spaced lines.

Referring again to Fig. 2, it will be Seen that a pair of horizontal transverse rolls 56 and 5'! which areY mounted upon Atransverse driven shafts, support and drive a wide endless band or belt 58,. The upper course of rthis belt travels over they table l1. The belt is driven through the medium of gears 5,9 and 6G and chain 6I from the roll 26 (see Fig. 1) to cause the belt 58 to travel in a clockwise direction and unwind or unroll the cotton batting I9 from its supporting roll.

The cotton batting is scored longitudinally at spaced points as shown at 62, Figs. 1 and 4, by means of a series of scoring disks 63 carried by the shaft 3S. The shaft 64 carries a series of presser disks 65 each of which is arranged in front of and cooperates with a presser foot 66, as shown in detail in Figs. 11 and 12. These disks 65 are in line with the lines of scoring 62 and serve to compress the material of the work pieces so as to guide it properly under the presser feet 66, as clearly seen in Fig. 11. The shaft 54 and disks 65 are driven or rotated by a sprocket andAcha-in driving connection 64a, 64b, see Fig. 6. The longitudinally aligned relatively sharp edged presser disks 63 and 65 successively compress first the padding layer and then both the top fabric and padding layer along the lines of stitching to form well` defined grooves or troughs thereby facilitating stitching and formation `as well as accentuation of the intervening tuft or pleat like portions of the final article. The sewing instrumentalities or units of the present machine each comprises the usual needle bar support 6l', needle bar 68 and needle 69. The needle bar and needle are capable of vertically reciprocating movement and are allowed a forward and rear-1 ward. tilting. or swinging movement about` the mechanism being that the presser feet (i6V are forked at their forward endsand that one of the presser disksl65 is positioned between the forked ends ofre'ach presser foot to rotate therein.

Each of theneedle bars is adapted to support one or more needles, dependent upon the number yand proximity of the rows of stitching to be applied tothe work. The needles 69 are supplied with thread fromv spools H supported in conventional manner upon a horizontal shelf 12, the thread. being guided by means of vspaced guides E3 and 14. The .looper mechanism (not shown) Y of conventional construc- 36 of the taut applying endless belts.y ForlthisV purpose, see particularly Figs. l, 2 and'l; there is provided at the rear end of the machine a stripper which, as shown, comprises a Vrod or shaft Sil having a freely rotatable sleeve 8l thereon.- The shaft is mounted at itsopposite ends upon the upright frame members 25. j The' finished work pieces pass beneaththestripper.

and engage the sleeve thereof which applies a The operation` 'ofthe machine is substantially as follows: A roll of foundation sheeting,v 21sy placed in position upon the supporting cradle 23, and the sheeting is drawn out and upward and `The laid over the lowerseries of endless belts 3l. edges of the foundation sheeting are inserted between thespiked belt 35 andthe cooperating smooth belt 34 so -that the'pins or screws 36 in the belt 35 will penetrate theA sheeting. The sheeting is stretched transversely into taut condition when applied to the points of the screws. As stated above, the belts 3 5 diverge outwardly from the front end of the machine toward the needle mechanism and thus serve to maintain the sheeting in taut condition. A roll of cotton batting Y I 9 is now placed upon the conveyor belt 5S and supporting table Il and unwound and laid over the sheeting 22. The two layers of material are drawn forwardly and passed between the superimposed upper and lower series of endless -belts 46 and 3|.v The drive mechanism for themachine is now set into operation whereupon the cooperating upper and lower pairs of endless belts move the interposed layers of material forwardlyy through the machine, while the rotatingscoring disks 63 function to score the cotton batting at predetermined points, for example, `along the lines 62. A supply of cover pieces i6 has beenjplaced upon the platform l5 and an operator at each side of the platform places a coverpiece over the cotton batting, with the long edges of the cover pieces being placed in close proximity one to ane. other. Each cover piece is notched out at its long edges so that the workman canl align the' notches with the scored lines formed in the pad-` ding and thus ensure the vproper positioning of Y,

The mechanism for operating the needles enter beneath the presser feet 66 in proper condition to be engaged by the vsewing needles 69. As the machine continues to operate a series of stitched upholstery pieces, such as the specimen piece in Fig. 9, issue at the rear or eXit end of the machine. These pieces are connected together by continuous lengths of the found-ation sheeting and cotton batting, the three being stitched together by longitudinal rows of stitching. As the work pieces issue from the machine the stripper bar 80, 8l engages the continuous length of work pieces and releases or withdraws the foundation sheeting from engagement with the taut applying pins or screws 36. The upholstery material or pieces may now be stacked in piles in the continuous lengths in which they issue or the several pieces may be separated by severing the foundation sheeting and cotton batting at points located between the adjacent cover pieces I6.

It will be understood that a common source of power is employed to operate the several conveyor belts, scoring disks and presser disks, as well as to operate the sewing needles and looper mechanism.
