METHOD AND MACHlINE FOR ASSEMBLING AND, UNITING FRAME MEMBER S.

Application filed March 18, 1925. SeriaLN'o. 16,582.

which finally bring about an improved method for uniting said frames around the edge of the center medium. When em ployed for installing curtain windows, my machine not only mounts complementary grommet-like frame members upon theop-' posite faces of the curtain or other'carrying material, but is further capable of uniting said frames. and binding the inner border a plurality of the curtain about the marginal edge of the center medium to make a Weather proof joint therewith.

In the specific-embodiment herein disclosed, my machine is shown as equipt with i of separate interconnected. crimping tools which are adapted to be introduced as a unit into asuitably shaped hollow grooved expansible male sheet metal frame member subsequent to its assembly into a nestled co -acting'female frame memher, and by the operation of said tools, simultaneously indenting or crimping said male member into interlocking engagement with the female member at plurality of spaced pointsv disposed longitudinally of said'members. The use of my improved machine serves to eliminate the need for individually. indenting crimp cleats between said male and female frame members or for otherwise separately drawing up a number of spaced screws, staples, prongs or other fastening devices when used for uniting complementary frame members.

Said machine is particularly adapted to interlock twopart window sash framemembcrs, such as are commonly employed to bind a sight pane into an automobile curtain, side panels or the'like which may be fashioned from leather, fabrics, fibre board or similar ,carrying material. As applied to vehicle curtain lights and especially back curtain sights, a set of complementaryframe members are preferably disposed on opposite sides of the pane or other centerv proof. binder between the pane and its surrounding curtain fabric or carrying material.

The primary object of this invention is to provide for a simple and effective machine and method capable offacilitating. the rapid and economical installation of curtain Window assemblies to thus fully meet pres: ent day production needs in the automotive industry. .To accomplish this end, I preferably use a conventional press but equip its traveling ram with frame uniting means which in the present instance comprise a pluralityof crimping tools each, rotatably mounted on interconnected spindles, and by imparting an oscillatory movement to said tools, I simultaneously. indent a series'of spaced crimp cleats between the assembled male and female frame members and thereby minimize the time and cost of. mounting curtain light frames when assembled on a productive scale; It is pointed out that the present invention is directed toward suitable mechanism designed to attain this end and does not lay claim to the indicated interlocking process per se.

Embodied herein are also other features of structure and method steps which insure the desired rapid and proper binding of other external the frame and its pane into the curtain, all

of which will be set forth in detail herein' after. N I

Fig. 18 is a plan view of the frame keeper piece while Fig. 19 shows a cross-section of same as taken along line 1919 of Fig. 18. Referring first to- Fig. 1, this represents a suit-able hand-operated upright press of the conventional G frame type which in its 'entirety is designated by the letter A. The frame proper A may be provided with a relatively short vertical guide Way A in which is slidably mounted a traveling head or ram A; adapted to overrun the lower transverse face of said guide. The ram may further be equipt with a suitably disposed balance lever A carrying the counterweight A The lower leg of said'frame has a foot flange A and this may be fashioned into the relatively long platin A disposed trans versely to the vertical plane of the frame proper. Said platin is suitably spaced with respect to said lower transverse face. of the guide A to constitute a frame gap therebetween. Superimposed upon the topface of said platin is a cover plate or die block A equipt with shallow endless groove or recess A adapted toreceive and seat the female member of the two part sheet-metal curtain light frame. 1 It is pointed out that said die block A serves essentially in the capacity of an abutment adapted to oppose the thrust abutment means is not intended to be specifically directed toward the structural features shown in the drawings but broadly comprises any similar or equivalent element that might serve the indicated purposes.

Attached to thelower or bottom face of the ram A is a transversely disposed retaining plate A which is adapted to travel with J plate may be equipt with complementary 0 A each provided with plus adapted to e'n gage therespective links A and A The upper free end of said links pivotally engage the spaced lever arms A and A, re-

spectively, and these arms are tied together by the lever oke A and-turn about the fulcrum shaft Said yoke is provided with a manipulating handle A and it will be apparent that when said handle is moved from its vertical or normalposition shown shown correspondingly shift the slidin ram A and its retainin plate A,, from t e'ir outmost position wit' respect to the block into the evises such as p by means of screws such as B as shown in Fig. '7. F rcely mounted within said slot B is a rack slide or reciprocating clement B and this may be actuated by means of the shifter lever B As indicated, this lever may he of the bel crank type fulcrumed on an extended portion of one of the side flanges and adapted to be raised and low ered therewith.

One leg of said lever is equipt with a shifting handle B while its other leg is proyided with a projecting pin B adapted to engage a suitable slot B by means of which the slide or element B. may be shifted laterally between its full and its dotted positions indicated in Fig. 5.

i forming or crimping tool spindle B equipt with a shank B -having an enlarged actuatmg gear segment B wh1ch latter member may be fitted into any one of said counterbores and supported by its shoulder such as B The shank B maybe recessed into a socket for receiving the crimping tool C and this may be locked in place by the set screw B The referred type of crimping tool is shown in detail by Figs. 3 3 and 3. The tool proper has a flattened shank portionC adapted to fit into'the respective recessed spindle shank B This tool is further provided with a reduced neck portion G while its free end is equipt with a head element comprising oppositely disposed beveled toes C and (1 respectively. As shown in Fig.

3 the overall length Z of the oblong head is made greater than its width-dimension 7), while the height it is made relatively short for reasonsthat will appear hereinafter.

As will be understood, the spindles B together with their inserted tools are intended to oscillate freely within their respective mountings. In order to simultaneously operate all the spindles, the slide or reciprocating element B is preferably equipt with a series of inset rack segments such as B which are adjustably secured to the edges of said slide so as to properly engage the respective spindle gear segments such as B 3, and simultaneously impart. a rotary movement to the aligned tool heads when ever the lever B is shifted within the prescribed limits of travel. If desired, any number of additional tool-spindles may be similarly mounted andas will be apparent from Fig. 5', certain of these spindles may be located adjacent to the transverse ends of the spindle holding means B by suitably slotting the rack slide at B as indicated. The spindle disposition is preferably such, that the elongated head of the respective crimpingtools C will align in such fashion that theymay readily enter the mouth of 86 an endless expansible groove part formed in the male member of the curtain light frame. V 1

1t willbe further observed that the relatively long spindle shank B projects considerably be ow the; bottom face of either side flange B and B Intermediate certain of the respective spindles and extending a little below the extremities of said cr1mping tools a series of inserted upright bridge strips B depend from the spindle holder B The spaced strips are intended to freely enter and align with the mouth of said expansible groove part of the male frame member and tightly thrustsaid groove into close engagement with its co -acting female framemember prior to interlocking the frame members together. The bridge strips B be-' ing slightly longer than the extremities of the tools C, serve to protect said tools against any direct thrust which the manipulating handle might otherwise exert thereon.'

Referring further to the spindle holder B this is equipt with a flat pressure pad 110 the opening through which is preferably but not necessarily disposed to encircle the downward projecting portions of the various spindle shanks B and this opening is made sufficiently large to encompass 115 the perimeter of the complementary nestled frames and abut the block A so as to snugly hold down the interposed fabric surrounding said perimeter and prevent wrinkling thereof, as shown. The bottom face of the pressure'pad is mounted to fall somewhat pressure pad is designed :to be resiliently hung with respect to holder 13 by means of a series of adjustable screws such as B shown in F 12, which screws are threaded in registering holes suitably disposed in,

the pad B,,. The enlarged head of said screws may besu ported upon a countersunk shoulder B formed in the spindle holder as shown, while the lower portion of the screw holes maybe recessed to re' 1 .ceive the spiral springs such as B which thrust against the pressure pad and serve to 'yieldinglyholcl samein an adjusted spaced relation with respect to the holder B As a further refinement in design, .at

'tention is directed to the shouldered tit f snap means 13,, of which several maybe pgtsition by compressingthe thrust springs mounted in the side or end walls of the-pres sure pad. Thesetits slightly project'Iinto :the hollow, space formed in said pad. B and'may be snapped back o-uttheir normal As is best shown in Fig. 10, the purpose of "these tits is to hold up the male frame member. in its suspended position prior to performing the indicated cleating operation, said tits serving in the capacity of gripping means for manipulating one-of 3 Taking up now the purpose of my machine as more specifically applied to the cleating ofcurtain light products, this will be made clear by further reference to. the

structural details pertaining to the sheet metal frame members that are to be' united about the edge of a pane or other suitable center medium. :As disclosed by Figs. '13 to 19, the letter-D representsjin its entirety anendless outer frame member, while E is the transparent sight pane mounted therein. The frame D may be provided with a crosssectionally V dishedshaped offsethaving complementary intu'rned marginalflanges forming an annular undercut receiving slot D th'erbetween which -is preferably disposed around the contour of said pane to constitute the female part of said vframe.

In the present window assembly the curtain fabric F is intended to lie along'the "parting face of outer frame. .D-as defined by said inturned flanges. The pane E is I centrally disposed and spans the innermost of. the int-urued flanges and is preferably cushioned by the interposed" fabric F in the manner indicated in Fig. 10. The opposite .marginal "face of ,,-the pane E may. be grippedby aspecially shaped inner or backmg frame and this male member of the two-part frame 15 designated asa whole by I the letter G. i i This inner sheet metal frame comprises a bead-like pane engaging flange G which need not however be made endless as are the remaining parts of'this member; said flange is preferably but not necessarily cut away along one of the frame" sides and terminates in the respective socket parts G and G thus forming a gap therebetween.

The inner frame G is further provided with a relatively narrow grooved male part Gr comprising side walls G and Gr which are disposed substantially normal to the face of the pane and tied together by the integral Ttransverse wall Gr 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 vslotD, of the outer frame, the intent being that said trough shaped grooved male part shall register with and be adapted to enter any desired shape that may be given to the slotted female part.

When completely assembled upon the curtain fabric, the two co-acting frame membersapplied to acurtain window installation are finally brought into the. relation indicated in Fig. 14.. Prior to interlocking said members D and G, they are firmly sprung together thus interlacing and mak mg the curtain fabric take a circuitous path about the nested male and female part in the manner illustrated by Fig. 16.

While in this stramed or sprung relation, the male and female. frame members may be w interlocked by means of the described crimping tool. The width ,b of the tool-toes is made somewhat smaller than the spacing between the side walls Gr and (3: of the grooved male member whilethe length Z of said tool is made somewhat larger, to the-end that when a partial turn is given to the.

shankC of the inserted tool subsequent to the assembling of the members D and G, thiswill cause said to simultaneously indent or forcibly expand the side walls; if v preferred, the use of a greater toe pitch Z will serve to. cut through said sidewalls and thus form up projecting ear-like spurs which interlock' with the undercut edges of the described female frame member D.

Either alternative-indenture of said male part of the frame G may be resorted-to and 1t willbe seen that its overall width is now greater than that of the female slot D so as to positively interlock said frame together.

' It will be apparent that this cleating operation also securely binds the interposed cur-y tainfabric to the assembled frame and the use of a plurality of spaced cleats for unit- .ing the frame members insures ag'ainstpulling the curtain border out of its binding.

Subsequent to interlocking the assembled frame members about the pane as described,

the pane may thereupon stlll be conveniently slid out from between the spaced innermost flanges of the framemembers through said gap in the pane engaging flangeG As detailed in Fi 18 and 19, a keeper piece G may be emp oyed tospan said gap and hol Tthe pane in placeand this piece may be equipped with short projecting tongues G,

sition shown in Fig. 1, and that the tool car' rier is equipped with the described, appurtenances,'then the press is readyto' receive the complementary frames in the fashion indicated in Fig. 10. That is to say, as a first step in my method of installing a curtain window, the outer frame or female member .D is seated in the recess of the die block A while the inner frame or male member G is lodged into the pressure pad B and detachably suspended therein over the various snap tits'B in alinement with the seated frame D as showni As a' second step, the curtain F together with the pane E is introduced between said separated frame members and these inserted parts are mounted upon the seated complementary frame parts preferably in superimposed relation as shown in Fig. 10.

' As a third step the lever A is pulled down into its lower position as shown in dotted lines by "Fig. 1, andth-is'will cause the carrier and its suspended male member j G to be lowered into the assembled relation shown by Fig. 11. The fabric thereby becomes interwoven-between the nestled male part (hand its co-actin undercut female slot D and by further pu ling down on said lever, any augmented thrust on the ram will cause the bridge strips to snugly press and hold the two frame members inclose engagement preparatory to cleating theframes into interlocking. relation- It will be apparent that the pad B will at. the same time have been pressed 'up-closertoward the spindle holder B 'and that the pressure pad is made to thrust down upon the fabric around the entire perimeter of said'nestled frames.

\Vhile held in this strained relation, the

r shifter lever B is drawn laterally into the dotted position shown in Fig. 5, which in turn simultaneously partially rotates the various tool toes and this serves to indent or crimp spaced interlocking" cleats between themale and female parts of the c'o-acting frame D and G and this feature constitutes the.

fourth step in my method.

The lever B isnow again placed into-its raised or lowered as described, the free end.

normal or full-lined position which then permits the unhampered withdrawal-of the tool carrier and its associated parts from the upturned mouth of the grooved male frame part G Thereuponthe manipulating lever A may be raised into it's normal or vertical position which then completes the cleating operation as performed by my machine and allows the curtain together with its installed frame and pane to be removed as a unit from the abutment block..

In certain cases especially when a sight pane is'to be installed into the conventional fabric curtain, it is preferred to introduce such fabric between the complementary frame members in an uncut condition as re gardsthe sight opening, although itmay be expedient to cut cross slits 1n sald pane span- .ning curtain portion for the urpose of augmenting its take up and facilitating the described interlaced binding of the inner fabric border into the frame members, all without drawing inwardly or wrinkling that portion 9f fabric lying outside of the frame perimeter. After otherwise completing the frame assembly in the press, the curtain fabric when left to span'the pane, may thereupon be trimmed to make the curtain opening conform to the inner contour of the frame and thus remove obstruction to the normal transparency of the pane, and when resorted to, such trimming operation consti-.

tutes a final supplementary step in my method of installing curtain lights.

It will be apparent that the removable keeper piece G may, now be inserted-in place, but this feature does notconstitute any essential step in the described installation method since said keeper is primarily provided for pane renewal purposes. In the event that the use of my machine should be confined to mounting and uniting moulding-like complementar edge of a center medium, it will be understood that the'necessa-ry installationsteps will be substantially similar to those heretofore set forth except in so far as the omission of the inserted curtain element may frames about the modify or-simplify the described operations. I

Supplemental means are also provided to facilitate the proper operation ,of the machine, and to this end a lock device maybe used such as is shown in Figs.'8 and 9. This lock feature comprises an upwardly projecting stanchion H the lower end of which is set into. or otherwise secured to the rack slide B and adapted to move therewith through asuitableclearance hole cut in the retaining plate A One edge of the stanchion is dis posed to' move alongside the upright face of the ram guide housing as shown in Fig. 10- by dottedlines andin such fashion that.

said stanchion is made to cooperate with an L-shaped obstruction. While the manipulating handle A is of saidstanchion is obliged to ride; alongside said housing face and this serves as a stop device to prevent inadvertentl moving the shifter lever B out of'its fullined position shown in Fi 5. This stop device maintains the desired initial ali nment' on part of the various oblon crimping tool heads so as to,

prevent any a lique turning thereof until the assembled male and female frame members have been firmly pressed together and 'are ready for the described crimpingoperation.

As soon however as the carrier tool "a .pliances have been properly entered into t e a frame groove G, as'indicated in Fig. 11, the

free extremity of the stanchion will then have been sufficiently lowered to pass under the bottomtransvers'e edge of said guide housing and thereafter allow the shifter lever B to move the rack slideB into its cross-sectional position indicated in Fi 9. In the meantime, the heads of the crimpto indent a-crimp cleat between theassembled frame members D and G. While in said .oblique position, the respective tool-heads may not be raised without .tearin outthe frame parts and it is the further function ofv my interlockingdevice to prevent damage on this account' lAslongtherefOre as said stanehion'rides' under the bottom hous ing wall, the shifterlever B, is operative,

A properly turned to be unobstructedl-y removp snuglycl'amp "said frame members together,

' and. t

' ing only one, continuous specifically disclosed herein. Furthermore it is not. essentialythat the curtain .be ,fash ioned from fabric and like flexible materials I I clear the nest but the manipulating handle A cannot be raised until the shifter lever is brought back into its norinal position in; which the tool heads align with said frame groove and are able therefrom. a I My machine is likewiseapplicable to unit:

sufiiciently lar e to freely encompass and fed male and} female frame partsand which are then merely clampedbetween the outermost flanges ofthe complementary frames. It'wi'll also beunderstood that various changes in the details of my machine may be "resorted to such as making same elike, andthat while 'the described species of frame unitingmeans represents what is now considered f a preferred embodi- -ment of my'machipe the result attained -might be alent. meth dgggicated by-. substantially equiv- --heretfore escribed. an
