METHOD AND MACHINE EOR AssEMBLING AND UNIT'ING FRAME MEMBERS.

Application filed July 30, 1925. i Serial No. 47,156.

My invention generically relates to novel machine method for assembling anduniting complementary frame members serving as a moulding for a center medium, said process being performed in connection with a suitable press equipt with operable frame uniting ineansand with a reciprocating ram provided with improved gripping means adapted to pick up the center medium and convey one ofthe frame members therewith for assembly purposes; with these Outstanding fea-tures as a basis, a series of relevant steps are set forth which finally bring about an improved method for uniting said frames around the edge of the center medium.

Then employed for installing curtain windows, my machine not only mounts complementary gronimet-like frame members upon the opposite faces of the curtain or other carrying material, but is further capable of assembling and uniting said frames to bind the curtain about the marginal edge of the center medium.

In the specific embodiment herein disclosed, my machine is shown as equipt with a plurality of separate interconnected crimping tools adapted to be introduced into a suitably shaped hollow expansible. male sheet metal frame member subsequent to its assembly into a nestled co-acting female frame member, and by the operation of said tools, simultaneously indenting or crimping said male member into interlocking engagement with the female member at a plurality of spaced points longitudinally disposed along the contour of said members.

Said machine is adapted to unite window sash of frame members and especially such between for binding purposes, and when these superimposed members are united by means of my interlocking machine, they form a neatand effective tie or binder be-y tween the sans' and its Surreiindns Curtain fabric,

To accomplish this end, I preferably equip a conventionaly press with a ram carrying a plurality of crimping toolsy each rotatablyl mounted on interconnected spindles, and by imparting an oscillatory movement to said tools, I simultaneously indent a series of spaced crimpl cleats between the male land female frame members and thereby minimizev the time and cost of mounting curtainy light frames when assembled on a productive A further object of the present invention Vis to provide for certainim'proyements intended to supplement those embodied in a cleating machine such as has beenA disclosed in in cOpend-ing. application Serial No. 16,532 iile'tl March 18,- 1925-.Y TheseI improvements relate iiifpart tothe. use of va novel vacuum cup adaptedto convey the-trans-V dition, suitable means are provided for the simultaneous cleating of a plurality of our" tain light frames in close association upon a common fabric and thus provide for a style of curtain that is preferred by certain vehicle makers. I

Embodied herein are also other features of structure and method steps'which insure the desired rapid `and proper binding of the frame and its pane into the curtain, all of Y which will be set forth in detail vhereinafter.

VSaid ilanges may be attached tothe reaining plate A, Vbv means ot screws such as E, as shown in Fig., 5. Freelyinounted and B, therefor. disposed to form' l disposed i'e- Y ttoiii face of the retaining plate A, Y

between its full and its dotted positionsin-Y dicatcd in Fig. 5.

As is best illustrated by Figs. G, l2 and 13, the spindle holder B, is further equipt with a' series of spaced holes such as Bm, Bw et disposed adjacent to the margin ot said plate and preferably drilled r respective reentorcing llanges lB3 and 'Bp T he uppermost portion ot' said holes may be counterbored as B13, B13 etc. to provi-de tor the respective shoulders 'BW BM etc. Mounted within each such pla-te holes '1s a forming or crimping tool spindle equipt Vwith a shank Bm and an enlarged attuating gear segment Bm which latter member is intended to tit into anyone of said counterbores and supported by the shoulder such as BH. l The shank B16 maybe recessed into a socket for receiving the crimpingtool C and this may be lo'led in place by the set ser w The preterredtype of crimping tool is shown in detail by Figs. 3a, 3' and 3C. The tool proper has a flattened shank portion C1, adapted to lit into the respective recessed spindle shank Bm. This tool is further provided with a reduced neck portion C2 while its tree end is equipt with ahead element having oppositely disposed beveled toes C3 and C, respectively. As shown in Fig. 3, the overall length Z ot the oblong head is' made somewhat greater than its width dimension E, while the height it on the other hand, is made relatively short for reasons that will appear hereinafter.

As will be un-derstood, the spindles B15 toget-her with their inserted tools are intendedl Ato oscillate freely wzthin their described mountings. In-order'to simultaneously operate all Vthe spindles, the slide or recipro` eating element B, is preferably equipt with inset rack segments which properly engage the respective spindle gear segments such as B, and simultaneously impart a rotary movement to the aligned tool heads whenever the lever B, is shifted within t-hepre# scribed limit of travel. It -desirech'any number of additional tool spindles may be similarly mounted and as will'be-apparent from Fig. 5, certain 'of these spindles may be located adjacent to the transverse ends of the spindle holding means B1 by' suitably Slottlg the rack slide at B2l as indicated.

through their f The spindle disposition is preferably such that the elongated head of the respective crimping tools C' will align in such fashion that they lmay readilyV enter the upt-urnd mouth ot an endless expansible groove pa-rt formed in the male member o t the curtain lightframe. j

lt will be further observed that the relatively long spindle. shank B1G projects considerablyv below the bottom Vface of either side flangev Bg'and Bi. intermediate certain of the respective spindles and extending bef yond the lower extremities otsaid crimping tools, a series off inserted "upright bridge strips B22 depend 'from the spindle holder vrlfhe spaced strips are also. intended to treelyenter and align with the mouth ot said' expanslble groove part of the male frame member so as tol tightly thrust said groove into close engagement w'th its coatingv temale vframe member prior to interlocking the frame members together. a

Referring `further to the spindle holder Bl, this is preferably equipt `with a llat hollow pressure pad B23, the opening through `which is disposed to freely encircle the downwardprojecting yportions ot `the various'spindle Shanks B1G, as shown. The

f bottom face ot the pressure pad is-preterably mounted so as to tall vsomewhat below the plane of the distributed crimpingv tool eX- t'remities vwhile the upper face ot said pad B23 is purposelylept spaced from thelower face otsaid spindle holder Bi. The pressureA pad is designed to be resiliently hung` with respect to holder B1 by means of a series ot adjustable screws such; as Bmshown in Fig.

14, which screws are threaded in'registering holessuitably disposed in therpad B-ZQV rlhe enlarged head of said screws maybe supported upon a counter-sunk .shoulder vB25y formedin the spindle holder as shown, while the lower portion ot the screw holes may be recessed to receive the spiral sprin'g'l such as By, which thrusts against the pressure pad plate and serves to yieldingly hold same'in in adjusted spaced vrelation withk respect to the holder'Bl. Y f

The hereinbetore described structural de-y tails of my cleating machine are substantially Videntical with those set forth in my co-pending application previously identified. The present improvements aremore particularly directed to the use of a pneumatic vacuunr chamber-'such as is shown in Figs. l0 and 1l, which is designated in its entirety by the' letter' J and serves the ram. ,Said chamber comprises a resilient flared cup l1 prefer ably made of softrubber, leather or other flexible material, which is provided `with an aperture J2 snugly fitted to the enlarged head J3 of the cup shank J rllhe head d( is in turn recessed and lprtnided with a holi low `plug J4 having a central hole 5 and also a Communicating transverselydisposed holel lll() i (Il as indicated. Tightly fitted into the outer or Vfurthermost end of said transverse hole 'is a tight joint With respect to the face of the"V pane which it is intend-ed to grip. Then the cup J1 is firmly pressed against the sight pane E by means of an inward' movement of the ram, it Will squash the rim ill in the fashion shown in Figs. 12 and 13, and thus cause a squeezing' out of some of the'air previously confined in the enclosed cup chamber, Hence, When the ram thrust between the cup and the pane is relieved, a partial vacuum Will have -been established Within the enclosed cup chamber and this serves to grip and suck the pane against the sealed cup edge J1 for manipulating and conveying purposes as will be more fully pointed out hereinafter.V A'release of the pane may be effected at Will by pressing down on the vent lever J8 which then reestablishes the full atmospheric pressure Within the vcup 'chamber and breaks the vacuum, thus allowing of selectively conveying the pane with respect to the ram movements.

As to the location of the vacuum cup, it Will be observed that this is disposed in a substantially central relation with respect to the desired position of the pane upon the block and that the cup shank J3 is snugly fitted and made to project'through a. suitable socket element formed in the spindle holder B, as shown in Figs. 12 and 13, While the shank projection engages a longitudinal slot in the slide B7 and acts as a stop therefor. Y

As a further refinement in design of my cleating machine,` attention is directed to the extension irons K, and K2 Which as shown in Figs. 1 and 2, may be attached to any convenient parts of the frame liousir-.a` for the purpose of supporting a plurality of spaced gauge pins such as lq and' K4, respectively. Said irons are each preferably provided with a longitudinal slot and adjust-ably fastened to the frame by means of cap screws such as 'K5 or the likefwhich adjusting means permits of shifting the location and pitch between the pins K3 and K, to meet requirements.

l/Vhen making up side or back automobile curtains in production, it is 'customary to provide the saine With spaced knob eyelets or grommetdike openings (not shown) which are intended to lit over suitable the structural fastening devices or studs disposed around y curtain light vwith respect to the particular shape given to said fabric. Y

Taking up now the purpose of my achine as more specifically applied to the cleating of curtain light products, this will lie-made apparent by further reference to details pertaining to the complementary frames that are to be united about the edge of a pane or other suitable center medium. rllhe details of the frame members which bind the curtain fabric and form a moulding for the edge ofits sight pane, have been quite fully described in my co-pending application previously identilied, and since these features per se form no essential part of my invention, it will suffice to briefly define the general characteristics of a specific style of article upon which my cleating machine is intended to operate. ln the present disclosures,.the letter l) in Figs. 12 and 13 is intended to represent in its entirety` an endless sheet metal outer frame .member While Eris the transparent pane lthat is to be mounted therein. The frame D may be provided With a crosssectionally dished Ashaped offset portion having complementary inturned marginal flanges such as l), forming an annular undercut receiving slot 'D1 therebetween which slot may be disposed around the contour of said pane and constitutes the female member of said frame.

ln the present Window assembly, the curtain fab fic l? is intended to lie along the partingrface of the outer frame D as defined by said inturned flanges. The pane E is centrally disposed and spans the innermost of the inturned flanges and ispreferably cushioned by the marginal edges of the interposed fabric ll in t ie manner indicated. The opposite marginal face of the pane ll] may be gripped by a specially shaped inner or backing frame and this'male member of the two part frame is designated as a Wholel by the letter G. I

Said inner sheet metal frame comprises a bead-like pane engaging flange G1 which need not however be ma Le endless as are the remaining parts of this member; instead said flange G1 is preferably cut away along one of the frame sides so asvto form agap to permit of the endWise renewal of the interlocked pane such for instance as is disclosed ful ' groove.

in the .Bishop Patent 1,587,739 granted May 12, 1925. The inner frame G is further provided with a relatively narrow gro'oved` male part G,L comprising` a set of sidewalls G5 and GC 'which are disposed substantially normal to the face of the pane as shown and tied together bythe transverse Wall GT serving to close the bottom of said groove. The proper overall face dimension of this bottom Wall is determined by width of the female part or receiving'slot D1 of the outer frame, the intent being that said trough shaped grooved male part shall co-actv With and be adapted to enter lany desired shape that may be given to the slotted female part or parts. v

vWhen completely assembled upon the 'curtain fabric, the t-ivo .co-acting frame mem-A bers as applied to a curtain 'Window installation are finally .brought into the relation indicated in Fig. 13. Prior-to interlocking said members D and G, they are firmly lclamped or sprung together by means rof a superimposed ram thrust, thus interlacing and making the curtain fabric take a cir-v cuitous path about the nestled male and female parts in the manner illustrated.

made somewhat smaller than the spacing between the side Walls and GG *of the grooved male inemberivhile the length Z of said tool is made someivliat'larger, to the end that When a partial turn is given to the shank' C, of any inserted tool subsequent to the assembling of the .nestled members D and G,'this Will cause said toes to simultane' ously indent or forcibly expand the side valls and it will be seenthat its overall AWidth is noiv greater than that of the female slot D, and positively unitessaid frame to: gather. lIt will 'be apparent-that this cleating operation also securely binds the border ot' interposed fabric opening to the assembled frame and that it preferred touse a p1u rali t of s iaced cleats for unitinfr the frame nombers to insure aoainet pulling the curnarices, then the press is readytoreceive the complementary' frame and the successive installation steps as appliedfto a curtain Win'- doiv may be .describedIas follows: The first The Width of the tool toes isl step consists in seating the outer frame or female member D in the recess of the die block A8 with the transparent pane E set' -haudle A17 is ythen firmly pulled down to bring the ram into its inward position, which causes the iiin of the vacuum cup J1 to be squashed against the uppermost'face of the underlying pane and grip the same. By the subsequent raising of the handlejAm both 4the pane and the top-most orinner frame G Aare thereby. picked up and conveyed With the fram to assume the spaced relation With respect to said 'seatedr outer frame D that is f'lioivn inFig. 12 and this operation consti- .tutes the second step in my method. Y

fis a third step the curtainyfabric F is thereupon introduced and interposed betiveen v the separated. frame members and preferably made to lay upon the parting face DE ofthe loiver frame'D as indicated by F ig.

[any desiredtixed `position for the iii-p s 'curtain liOht frames may noW be located by slipping certain of the described fabric eyelets over the respective adjusted gauge pins K3 and Ki.

is a fourth step, the Vlever Anis again pulled down into its ininost position as snoivnin dottedrlines by Fig. l; this willv `cause the carrier together With itsy inserted vmale frame memberiG and the pane `E to be' conveyedv into the assembled position shown by Fig. 18. In the present style of frameythe fabric thus becomes snugly'inter- AWoven between the'nestled male part of the Alframe G and its'co-acting undercut female Vgroove Dl, and by further 'pulling dovvn firmly on said lever, vthe spaced brid'gestrips 'B52 Vare .intended yto snuglyv press aga-inst the bottom.A groovel Wall B,v andphold the two s frainemembers in clamped engagement preparatory to uniting the iframes intointerlocking-relation in the .fashion shown `in Fig. .14. Y lt; will be seen that thepressure pad Ba will at the same time have been pressed up closer toward the spindley holder B1 and that sai d-pad 4is made to firmlyV press down -uponthe interposed fabric around `the entire perimeter of said nestled frames, but suchV reiinements constituteno` essential featurein tli'erfourth'stepof the described operations.

lVhilethe frames are held in said clamped relation, the .complementary frames lare united about their'interposedelements and [this comprises the fifth step; in the present instance, said step"`is performed by draw-- .ing the shifted: leverr Bs'laterally Aintothe 1 1+ i v l V. v. dotted positionshoivn in Fig. 5, which Vin turn simultaneously partially-rotates. the arioustool'toessiieli as@3 and C4 an'dserves `posed curtain fabric F. The manipulating iiol iis.

to indent or crimp spaced interlocking cleats between the male and female parts of the cna-actingl frame l) and G. At this juncture, Athe valve lever JS Vis depressed to open the vent valve J, which breaks the vacuum within the flared suction cup J, and relieves its grip on the sane.

rlhe lever BS is now again returned into its normal or full-lined position and this permits the unhampered withdrawal of the tool carrier and its associated parts from the upturned mouthof the grooved male frame part G,.- rlhereupon the manipulating lever A1, may be raised into itsnormal or outmost positionV which then completes the curtain window installation as performed by my machine, and allows the curtain fabric together .with its inserted sight pane to be freely removed from the jaws of the press,`

all as is more succinctly set forth in the ap pended method claims. If desired, the manipulating lever A1,. and the shifter lever BB may readily be interloclied to facilitate the proper sequence of the described operations, suitable devices to accomplish this purposel being set forth in the aforesaid copending application and need not here be elaborated upon.

In certain cases especially when a sight pane is to be installed into the conventional fabric curtain; it is preferred to introduce suchy fabricl between the complementary frame membersV in an uncut condition as regards its sight opening, although it may be expedient to cut cross slits in said pane spanning curtainportion fonthe purpose of facilitating the described interlaced binding of the inner fabric border into the frame members, all without drawing inwardly or wrinklingf that portion offthefabric lying outside 'of the frame'perimeter.v After other-- wise completing the frame assembly in the press, therfcurtain fabricV when left to span the pane, may thereupon be trimmed to make the curtain opening conform tofthe inner contour of the frame and thus removeY derstood that the necessary installation steps will be substantially similar to those heretofore set forth except in so far as thev omission of the inserted vcurtain element may n modify or simplify thegdescribed operations.

As a further modifica-tion of the described ty 3e. of machine for eleatin'fr single curtainV Y b z2 light frames,itispointed out that the described disposition of therplu'ral tool spindles ymay readily ,be arranged to simultaneously cleat two separate curtain light frames into a common back curtain fabric. f preferred, the carrier may for this purpose be provided with two separate interconnected slide racks such as B7 and B, suitably mounted alongu side each other in the fashion shown in Fig'. 8, which results in producing ardouble curtain light frame assembly such as that indicated in Fig. 9 by the designation D and D, it being apparent that the shape lof the frame may be given any'contour that the purchaser may prefer. ln this instance, the two Slide racks are interlocked through a series of intermediate gears such as B17 which then connects said racksV BT and B, and cause them to travel in unison when manipulated from the common shifter lever B8. It will be seen that each of thek duplicate carrier' parts are preferablyv provided with independent vvacuum cups J1 and J1, the chambers of which communicate through the common vent pipe J6 shown in dotted` outline in Fig. 8.. This pipe is in turn commanded by a single vent valve J7', but in other respects the carrier appurtenances remainsubstantially similar to those previously described without essentially Vafl'ecting their normal mode of operation. ft will also be'apparent that when a plurality of curtain light frames are to be simultaneously cleated, it is expedient to provide for duplicate die blocks for the frame platen in order that the assembled frame may properly align withtheir respective tool carrier 'ap purtenances.

My machine is likewise applicable to uniting frames each pro-vided with a-series of co-acting male and female parts instead of using only one continuous Vgroove as has been more specifically described herein. 1 Furthermore, it is not essential that the curtain be fashioned from fabric and like fief;-

Vible materials since the method and devices herein'set forth may readily be used to bind a pane into a curtain made of fibre board or other stiff carryin'gf'm'aterials, but in that event it is expedient to initially cut the curtain. opening sufficiently large'to freely encompass and clear the nest-led male and female frame parts, and which areV then l" merely clamped between the outermost flan ges of thecomplementaryframes It will also be understood that various changes in the details of my machine may berresorted to, suoli as making the same power driven vinstead of hand operated and the like, all withoutdeparting from the spirit and scope therebetween, said method being performed by a machinefequipt with an abutment means and with a cooperating novable means served by assembly manipulating devices adapted to contact and pick up the center medium; lsaid method consisting); inA
