MATTRESS-SIDE-STITCHING MACHINE.

To all whom t may cm1/cern:

Be it known that I, FREDERICK W. H. Contr/rr, a citizen of the United States, residing in Canibridg'e, in the county of Middlesex and' State of Massachusetts, have invented an Improvement in Mattress-Side- Stitching Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings designating` like parts. t

This invention relates to a. mattress side stitching machine for producing what 'is commonly known as a roll edge 'on a mattress.

The character of the product of the machine is the same as that of the machine forn'iinp,- the subject of U. S. Letters Patent No. 1,342,423 granted to my assignee on the 8th day of June, A. D. 1920, to which reference may be had to facilitate an understanding of the present invention, which may be regarded as an improvement thereon.

The present invention relates mainly to the feed mechanism which operates to present the mattress to the twine operating instrumentalities of the portion of the machine called in that patent the stitcher, and to Jeed or advance the mattress after each cycle of operations of thel stitcher to the proper position for the next such cycle.

In an embodiment of the present invention the stitcher may be the same as shown in said prior patent, as the stitch forming instrumentalities form no part of the invention except as a unitary element in combination with the novel mattress supportw ing and feeding mechanism.

In the machine forming the subject of the present invention the 'stitcher is stationary and the mattress is supported on a table located in proper relation to the stitcher and having a smooth top on which the mattress slides easily, and the invention consists in part in the combination with the stitcher and table of a system of belts and actuating mechanism therefor which facilitate, or contribute to the movement of the mattress on the table in the manipulation by the operator and in the automatic feed movement which in cooperation with the stitcher effects the proper spacing of the the said jaws are moved further apart to disengage or release the mattress,y are then moved along over the mattress in the direction opposite to the feed, are'then moved towards one another to clamp and `compress the mattress between them, and then are moved in the'direction of the feed, carrying` the mattress with them the distance desired between the individualknotted loop stitches, commonly about two inches, which completes a cycle of feed operations, at the end of which the feed mechanism remains holding` the mattress clamped while the next stitch is made by'I the stitcher.

Another portion ofthe` invention consists in the combination with the components above referred to of a pair of guides, shown as rails or bars which, are pressed yieldin'gly against the top and ybottyom surfaces of the mattress on lines of considerable length parallel to the side being' sewn, which conf tribute to the guidance ofthe mattress in the feed movement, and to the holding of the mattress in the stitching operation.

Another `portion of the invention comprises certain awls and actuating mechanism therefor, timed relative to the feed, by which the said awls are caused to penetrate the side of themattress and then to have a pivotal movement, onetowards one, and the other towards the other cornerfof the mattress about to be stitched, the purpose being to square the side of the mattress, if v'as sometimes is the case, it is somewhat dis,- torted, and to insure that the stuffing fills both corners before they arrive at they point at which v`the knotted loop stitches are formed in both corners at ther same operation. t

The invention 'further consists in various combinations of mechanism and featuresef construction and arrangement which will appear in the description of the embodiment of the invention illustrated in the accompanying drawings, in which Fig. 1, is a plan view, diagrammatic in character, showing the general relation to one another of the parts mainly concerned in the support and feed of the mattress, the stitcher being omitted; I

Figs 10 and 11, sectional details illustrating the operation of the regulating awls.

The mattress supporting table 2, has a recess 22, in the side where the feeding and stitching mechanism act upon the mattress 200, as best shown in Figs. 1 and 2, thus affording the working instrumentalities access to the lower surface of the mattress.

The specific construction of the stitcher or mechanism that acts on the mattress and twine or thread in making the stitches of the seam constitutes no part of the present invention except as a unitary element of some ofthe novel combinations, and said stitcher may be of the construction set forth in my prior Patent No. 1,342,423 before referred to, a sufficient portion of the mecha nism being herein shown to indicate its combinative relation to the other elements of the present machine.

Such portion of the stitcher is best shown in Fig. 2, in which the needles are marked 100, and the shaft on which the hollow cam shaft of the stitcher is mounted is marked 20, and is driven by a power shaft 21, (see Figs. 1 and 3) suitably connected therewith as by a worm and worm gear.

The feedy mechanism proper by which the mattress is advanced between successive cycles of operation of the stitcher comprises a pair of jaws or clamp members 3, each pivotally connected at 4 with an arm 5 fixed to a rock-shaft, marked 6 for the upper jaw, and 7 for the lower, said rock-shafts being journaled in the main supporting frame of the machine as best shown at 8 in Fig.

The jaws 3 have long and broad mattress engaging faces which are shown as provided with cross ribs of rubber or clinging material and lthey thus compress a considerable portion of the mattress between them as is well shown in Figs. 2 and 4, and by their pivotal movement on the joints at 4 they may be moved towards and from one another to clamp the mattress and torelease it, and they are moved forward in the direction of the feed when closed upon the mattress, and backward when opened, bythe action of the arms 5 when the rock-shafts 6, 7, are oscillated by the actuating mechanism which will now be described.

The feed jaws 3 are actuated in all their movements by a cam 10, on the main shaft 20, said cam acting on a roller 12 on a link or bar 13 connected at its ends with crank arms 14 on the rock-shafts 6, 7, so that the upward movement of the bar 13 causes the forward feed movement of the jaws 3, in the direction of the arrow in Fig. 4, and the downward movement produces the backward move-ment of said feed clamp jaws preparatory for the next forward movement in which the mattress is advanced to the position for the next stitch.

The same cam surface acts upon another roller 15 on a lever 16 pivoted at 17 on the frame, and provide-d near its free end with a pawl 1S adapted to engage with a shoulder 19 on a vertically movable slide bar 24, connected near its upper end by a universal joint with a connecting rod 25, which is connected at its other end with one end of a lever 26 fulcrumed on a block 27.

The other end of said lever 26 is connected by a rod 28 with the upper jaw of the feed clamp as best shown in Fig. 4, and the ball and socket or universal joint connections with said connecting rod 28 accommodate the feed movements of the clamp as well as the pivotal movement of the aw 3 at 4 and the rocking movement of the lever 26.

The fulcrum block 27 is capable of movement on an upright 30 forming a part of the main frame and is pressed against a stop and l guide block 531, fixed upon said upright, by

a spring 32 which may yield after the jaw v comes to its bearing on the mattress, so as not to put excessive pressure on the mattress. The block 31 is provided with a steady pin 33 entering a guide passage in the fulcrum block 27 which` prevents said fulcrum block from turning on the upright 304 while permitting it to rise in overcoming the force of the spring 32 1n case the mattress is not sufficiently compressible to permit the full movement of the feed clamp jaw.

The lower end of the slide bar 24 acts through the intervention o-f a spring 320 (see Figs. 3 and Li), on a lever 260 yfulcrumed at 270 on the main frame and connected at its other end by rod 280,A with :the lower clamp jaw 3 so that-the upwardmove ment of the `slide barv 24 which; jcauses the downward movement of the upper yfeedl clamp, jaw also causes the upward;y movement of the lo-wer jaw andcloses the clamponk the mattress with a yieldingy pressure owing to the action of the

springs

82, 320,'so that the stuiiingof the mattress is notunduly cont pressed. The connections of the rod y280 with the lever260 and with the lower clamp jaw are by` universal (ball and, fsocleet) joints, thus `accommodating kthe various movements ofthe lower feed clamp jaw..

By having the clamp opening and closing member such as the slide bar 2e actuated from itsL cam through the fintervention of the pawl 18 or equivalent connection, the said bar can be released when the machine is stopped, so that the clamp jaws maybe open to permit free manipulation. ofthe mattress on the table, even if the machine is stopped with the cam roller 15mn-.the high part of the cam l0 which is theI position to close the clamp, in theoperation of the machine. c j

The feed clamp 3, 3, and `actuating mechanism thus far described by which it yis given its opening and backward, followed by its closing and forward movements,constitute the feed mechanism proper fandl serve'fto advance the mat-tress properly, step step in the intervals between successive cyclesof operation of the stitcher by which they knotted loop individual stitches are produced, but. in order to relieve-said feed mechanism of the drag of the mattress on the table and facilitate f the movement of the. mattress over the table an auxiliary appliance is .provided which will now be described.

A number of belts 40, best shown ,in Figs. l and 2, are mounted on pulleys tl fixed ony shafts 42 mounted in bearings below the table at right angles to the direction offeed of the mattress, with theV periphery of thel pulleys extending through openings in` the table so that the upper stretches of thebelts lie on the top of the table between it and the mattress as shown in Fig. 2, and; are parallel with the direction of feed.. The auxiliary feed belts are preferably made ofy fabric or material having more frictional hold on the mattress than thetable top `so as tol carry the mattress along with the-m when moving although they will not interfere materially with the movement ofi thc vmattress in the manipulation by the operator in placing it in position to begin stitching, yor in turning it when the end of the side being stitched is reached.

Inorder to contribute to the feed operation after the mattress has been properly positioned in thefeed clamp, 3 the belts 40 are moved an, amount corresponding tothe Vfeed at the same time and speed as the feed clampfinitsforward movement as follows. One of the shafts l2 has tired upon it aratchetf wheel t3 (seelfig. 9) adapted to be: acted upon ,by ya pawl 4:4011 a carrier-.4:5r loosely mount-ed onsaid shaft and connected with a link 4.6 extending toy and connected with a crank arm 47 on the rock shaft 7 .which operates the lower jaw ,of the feedvtravel in'unison` with said clamp, yand saidy belts carry the body ,ofl the mattress lying upony themr along in unison with the part gripped by the feed clamp without-any drag on said clamp, and/inthe backward *f movement of the open feed clam-p ythe p-awl dal turns back` over the ratchet wheels?) without affecting the belts and mattress thereon. f c f f yIn yorder tol facilitate the handing of the mattress by the operator as .inf ruimingit `back afterone side has been stitched preparatory to :turning and ,positioning rit ,for fstitchingthe next side, thebelt shaft l2 is -connectedfas by sprockets and chain 48,

with a sha-ftf2l0 inlinewith, but normally disconnected from, thefpow-er shaft 2l (see Fig; 3) andk a clutch 49 is provided which `enables theaoperator atwill to `connect shaft 2IO`with the driving shaft 2lj-causing the feed belts 4() to be run in the backward di# krection at a suihcient speedto carry vthe matt-ressk back rapidly to position for beginning t-he stitching. ff

f The pawl; et is disengaged `from the .ratchet ywheel 13. before the clutch dit) is engaged, and the cam shaft of the stitcher and the actuating' cam yof the feed mechanism are disengaged from the mainy shaft 20 at this time, provision of any suitable or usual kind beingmade by which the engagement .may be effected so that the feed mechanisnr may be operated whilethe stitcheris notrunning, and the stitchei-.may then be brought into operation in proper timing relatire to they feed. c f

Thek mattress is guided and` positioned or gagedv relative to the stitching instrumentalities `by a pair of guide bars ki0 which bear-:oni thetop and bottom surfaces of the mattress as nearyas practicable to the place of action lofthe stitcher mechanism as shown injFig. 2and thus gage the upper and ylower surfaces of .the mattress relative to said mechanism, said vbars bearingon the mattress for a considerable distance parallel with the edge beingk stitched both 'in' advance-of y and beyond 'the point. at which the stitching takes place as appearsin Fig; 4.

rThe-said guide bars are pivote-ily sup- ISO ported at their rear ends, that is, beyond or past the stitching point, on the roc-k shafts 6, 7, of the feed mechanism proper, and at their forward ends they are curved so as to afford a flaring entrance for the port-ion of the mattress coming into the space between said guide bars as the stitching progresses.

y rllhe outer ends of the bars 50 are co-nnected with hangers shown as shafts 52, 53, carried by frames or radius arms 5.4 pivota-lly supported on the rock shafts 6, 7, and the upper shaft 52 is connected by rod 55 with a crank arm 56 on a rock shaft 57 having an opposite crank 58 connected by a rod 59 with the shaft 53 of the support for the lower guide bar.

A spring 60 acting on a short arm connected with said rock shaft 57 tends to turn the same in the direction to move the lower bar 50 upward and the upper bar downward and thus to cause said bars tobe pressed firmly but yieldingly against the mattress between them, while an opposite arm of said rock shaft 57 is connected by a link 61 with a treadle 62 by depressing which the operator can separate the guide bars 50 widely so as to release the mattress or permit one to be -adjusted in position relative to the stitcher mechanism by the operator who stands at the left of the stitcher mechanism as seen in Fig. 1 Where the mattress can be manipulated conveniently to position it at the beginning of the stitching of each side `in which the feed is from left to right.

Owing to the recess 22 in the table the mattress is supported and held in the vicinity of the stitcher mechanism solely by the feed jaws 3, 3 and the guide bars or clamp 50, 50 which press equally but yieldingly against the top and bottom of the mattress so that any slight variation in vertical thickness is distributed equally at top and bottom instead of appearing wholly at the top as would be the case if the mattress was' supported on the table at the stitching point, and said feed and guide clamps hold lthe mattress in advance of and beyond the stitching devices suflicient-ly to control it at the beginning and end of a seam.

It sometimes happens that the side of the mattress is not quite square so that the upper and lower corners instead of being in a vertical line as shown at the right and left hand in Fig. 2 upon arriving at the stitching point tend to stand a little out of vertical alinement which if not corrected might make the upper and lower edge rolls somewhat unequal, to the detrimenty of the appearance of the work.

The squa-ring or regulation of the mattress when such correction is required is performed by the regulating awls 7 0 and their actuating mechanism the relation of which to the stitcher mechanism is best shown in Fig. 2 and the details of which are shown in Figs. 6, 7, and 8.

The said awls 70, one for each corner of the mattress, are xed in the stocks 71 which are pivotally mounted in a carrier 72 on a slide 7 3 mounted in guides 74 in which it is movable'in the direction to cause the awls, when in normal position in the carrier as shown in Fig. 6, topenetrate the side of the mattress, the upper awl between the middle and the upper corner, and the lower awl in like relation to the lower corner of the mattress as will be understood from Fig. 2.

The slide 7 3 is actuated in its movement towards and from the mattress by another slide 75 similarly movable in the guides at 74 and having affixed to it a block or angle plate 76 which extends over the top of the carrier slide 7 3 and is connected by a link 77 with a lever 78 fulcrumed at 7 9 on the frame and having a cam roller in engagement with the groove of a cam 8O timed relative to the feed cam 10 to cause the awls to perform their action on the mattress in the interval between successive feed movements thereof.

The slide 75 is connected with the slide 7 3 to actuate it in the forward or penetrating movement of the awls by a latch or hook 81 pivoted at 82 on the block 76 and acted upon by a spring 83 which tends to turn it into engagement with a projection 84 from the slide 73 and thus to lock the two slides together when they are in the normal position with the awls withdrawn yfrom the mattress as shown in Fig. 2.

kThus when the slide 75 advances towards the mattress it carries the slide 7 3 with it until the awls have penetrated for their entire length as indicated in Fig. 10 at which point a trip cam 85 acting on a pin 86 on the latch 81 disengages the latter from the projection 84 after which the slide 75 may continue to advance without producing any further longitudinal or penetrating move- Inent of the awls, in which advance it actuates the awls in the` pivotal movement which will now be described.

The pivoted awl stocks are each provided with a cam arm 90 and are acted on by springs 91 which keep said arms 90 against an actuating surface on a plate 92 on the end of the slide 75, and when said slide is latched to the slide 73 as shown in Figs. 2 and 6 the said awls are retained in line with the slides. As soon as the penetrating movement is completed and the latch 81 has been tripped the slide 75 continues its advancing movement and by plate 92 acts on the cam arms 90 and thus rotates the awl stocks 71 and causes the awls to swing or move laterally towards the corners of the mattress as indicated by the dotted lines in Fig. 6.

It has been found desirable to have the axes of the awl stocks inclined as shown so that in the pivotal movement the awls noty only swing upward and downward respectively but both swing forward in the direction ofthe feed of the mattress as appears in the plan view, Fig. 7, in which the slide 7 5 is shown as having completed its movement relative tol the slide 73 from the position shown in Fig. G, in which the latch 8l is about to be disengaged from the/projection 84C to release the slide 73.

In 'the return movement ofthe Aactuating slide 75 the cani plate '92 first recede's, permitting 'the springs to act to swing theawls back into line, and then the block 76 engages the projection S4 and carries the slide '73 along with the 'slide 7 5 and withdraws the awls to the normal'position yshown 1n Fig.

2, the latch "S1 at the same `time engaging the' projection 84 preparatory for the nextr cycle of operation of the regulating awls.

The action of the awls in squaring the mattress when necessary is illustrated in Figs. lO and y1l. If either corner `falls away fromr vertical alinement with the other as indicated at the lower corner in Fig.v 10, the corresponding awl will lind the stufiing :material more dense between itV and the side fabric, and in its movement downward `and outward (toward the right in Fig. 10) and forward in the direction of thefeed it will force the stuffing and coveringv fabric youtward and bring it into verticalV alinement with 'the other corner as shown in Fig. l1. lh'ether the mattress requires such adjustment or not, theawls'insure thatthestufiing shall properly fill the fabric atthe cor-ners before arriving at the point w-here the'stitch is made,-thuscontributing tothe uniformity ofthe upper and 'lower roll-edges.

The operation is as follows The stitcher is stopped with the needles out ofthe material, vand' with `the pawl 18 disengaged 'from the bar 24 and consequently with the feed j a'ws3,3 widely separated, -and the operator by vdepressing the treadle 62 also se -paratesl the Vguide rails 50,' v5() so that the mattress may be moved freely between them. lThe mattress is then placed bythe operator with its side in proper relation to the :stitcher mechanism, the auxiliary feed belts 40 being run backward to assist in this operation if desired.

The treadlelGQ is then released causing the guide rails to *clamp the mattress yieldin'gly between them and the `machine is started. The pa'wl -18 engages the bar 24: andthe feed mechanism isset in operation, lthe jaws 8, -3 Aclamping the mattress and, `assisted by the

belts

40, 40 ycarrying -itforward yunder the guidance of the rails 150, 50 through which 'it slips, and then holding it while a cycle offoperations of the stitcher is performed, yat the end of which the jaws 3,13 move apart, then move back, and then close upon the mattress and move forward again and the operations Vjust described are repeated until one side ofthe mattress is stitched.

The'machine' is then stopped Aand thel mattress released from the feed and guidemembers as yat the'start, and the mattress is run back by the belts 40, l0 and turned quarter around on the. table and again adjusted to the stitcher after which the next side of the mattress is stitched, and so on until all four sides have been completed.

The regulating awlsO, act to adjust the side of the mattress by giving uniformity to the stuiiing at upper and lower corners, their 'operation ybeing performed inthe intervals between the feed steps while ythe stitching cycle is being'performed, and acting at a point in advance of the stitcher so as tor prepare the mattress for the action of the stitcher. 4

Some portions of thisV invention are applicable to, and might be embodied in a machine vwhich acted upon only yone corner or edge ofthe mattress at a time, and some'portions `or features of the feed mechanism mightbe:combined with other than roll edge side stitching instrument-allities.
