' JOHN HOWARD WAY, or PHILADELPHIA, PENNSYLVANIA.

RIVETIN G APPARATUS.

Application filed February 17, 1921. Serial No. 445,647.

T all whom it' may concern.' f

Be it known that I, JOHN HOWARD WAY, a citizen of the United States, residing in Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Riveting Apparatus, whereof the following Ais a specification, reference being had to I the accompanying drawings-, The invention relates generally to rivetingr apparatus and more especially to riveting apparatus useful in connection with the assembly of metallic window sash frames.

Window sashes such as are used in modern lire-proof building structures are almost universally constructed of standard metallic shapes. These Vshapes are cut to the proper lengths, and'those which are to become muntins and mullions, incidentally formed with tongues adapted to be inserted through appropriate apertures in those which ultimately constitute the perimetrical or side rails of the vwindowsash, and the protruding ends of vthe tongues subsequently headed over or upset` in effecting permanent assembly ot the structure. I-Ieretotore upsetting has been accomplished either manually by use of an ordinary Vhand riveting hammer, or by fusing the`protruding end of the tongue of the niuntin ormullion to obtain an analogous result. These methods have been found more or less objectionable, thefirston account of the high cost of labor involved, and the seconden account of unreliability of the jointformed due to burning ot the metal.

The object or" my invention is to overcome these difiiculties land to eli'ect the permanent assemblagelof structural steel window sash frames'with expediency and at a cost lwhich is not prohibitive. This I accomplish by aid of an apparatus which compriseso-ne or more pneumatic riveting tools wherewith are associated imlijvidual clan'iping devices by jwhicli the members of the window sash may be lirmly engaged locally at the regions lwherethe riveting is tofibe performed'.V

Means are ,also providedv forappropriately supporting thev sashes. and provision made whereby the 'pneumatic ,rivetingV tools may Vlee shiftedA from one position to another with respect tothe sash` so that theseveral muntins and mullions may be successfully 'headed over orupset asabove n0ted.

another The advantagesof my invention will be-l come readily apparent from the detailed description which follows:

Fig. I is a plan view, more or less diagrammatica-llyrepresented, of a window sash frame riveting` apparatus conveniently embodying my invention.

VFig. XI is a detailk cross section/corresponding to Fig. IV showing 'fa modiiied means by which the pneumatic riveting tool is secured toits vsupporting'slide carriage. J

Fig, XII is avfragmentarv Vside view of; the structure shown in Fig. XI. V i Fig. XIII is a] cross section correspond# ing to Fig. VII showinga modified form of clamping device; and

Fig.V XIV isa similar view showing still modification lof the Aclamping deff cross section vice.r Referring first toY the' complete forganiza plane of the artion as sctforth in Fig. I,.,it wi ll be :ob-V served to includeV aV table,` comprehensively indicated at 1, for, supporting the work to. be riveted, in this case shown as afmetallic sash frame F. This. table lwisbuilt upl comprises a seriesy of; transverse standards 2, 2,:which are united by .ai gi'iidev'faystruc? ture comprising sections 3, 3,-eXtending lat erally .about thetable. Surmouiited upon the standards 2, 2, are beams 5, 5, adapted to support the window. sash frame i li|`77 atthe proper level as will be bettei understood from further description. able in the guideways 3, are slide carriages (S upon which yare mounted pneumatic rive"- ing` tools 7 having associated with them, clamping devices comprehensively indicated at 8. yBy this construction, the tools 7, together with their associated clamping devices 8. may be shifted into alignment or registry with the inuntins and mullions, along the respective sides of the window sash frame which is supported upon the table. Standard metallic sashes of the type herein chosen for illustrative purposes, have their muntins and mullions provided, at the ends, with short tongues T which project through suit-able openings in the side rails, in order that they may be headed over or upset in effecting permanent assemblage of the window sash structure.

Referring now more especiallyjto the enlarged detailA showings of Figs. U. to VIH inclusive, it will be seen that the guideways 3 have a channeled cross section and that the lower slide carriage members 10 are formed with extensions 11 which cooperate with removable vtop plates 12 in holding tl e carriages tothe guideways. Bolted to each slide carriage is a bracket 13 formed with an integral split ring 14 by which pneu-l matic riveting tool 7 is secured to its car-V riage. At its top, the ring 14 has an upstanding lug 1G. to which is pivoted a hinge fitting 17 appropriately machined to receive an extension bar 18 to the outer extremity of which is vadjustably secured, in axial alignment with the tool, and forward of its front end', a clamping device 8 such as previously referred to. The hinge connections thus formed between the clamping Vdevices 8 and vthe pneumatic riveting tool mountings allow said clamping devices to be lifted and swung so that the window sash F may be readily placed upon the supporting table l initially,and also to permit subsequent shifting of the tools to vvarious positions along the guidewavs in effecting the riveting of the several muntins and mullions -of the window sash. n

Each clampii'ig device comprises a i'eetani gular housing 19Yconsisting of side members 20, 2O which are joined at their ends by cross bars 21 and 122,

y by bridging plates. 23 and 24A-(Figs, Il and endof the eXtensionba-r 18.

device is secured in adjusted positions upon the extension bar 18 by means of a set screw 26, which extends through the cap piece 25,-

Y The side members 2O ofV the housing are further united at their tops Clamping of the muntins or mullions of the window sash is effected by toggle mechanism which includes opposed 'pinch elements respectively designated, comprehensively, by the numerals 30, 31. In order to allow for sliehtJ variations in the thickness of the webs of the muntins or mullions ef the window sash, the pinch elements are preferably made composite, each accord ingly comprising` a series of aligned link sections 32 which are united by common pivot rods 33, 33. Said pivot rods are suspended at their opposite ends from the cross bars 21 and 22 of the housing 19, by means of the connecting links V35, 35. The pinch elements 30, 31 are respectively coordinated with groups of toggle links by which their movement is effected. Each of said toggle groups consists of a: rowof aligned links` iespectively in a row, and united by means' of a pivot rod 39. rlfhe opposite ends ofthe links 38 are in turn pivotally connected to the side members 20, 20 of the casing 19 by a rod 40. As best shown in Figs. V, X and X, the several links of the toggle mechanism are so shaped as tov be intermeshing with each other and with the sections V32 of the pinch elements, and it will be observed that the side walls 20, 20, of the housing are appropriately notched in carrying' out the scheme ofjintermeshing so that by this con? struction, ample stability Vis afforded the various pivot rods by which the links of the toggle mechanism are connected. y

The intermediate pivot rods 39, 39 of the two toggle groups are carried ror supportedi in depending ears 41, 41 of the coextensive sustaining bars 42, 42 which are suspended, at their ends, from a pressure plate 43 connecting` links 44, 44, said pressurel plate thus becoming a common means by which the toggle groups may be simultaneously operated. Said pressure plate is guided for vertical movement within theconiines of thel housing 19, and actuated through the instruf4 mentality of a master'link 45, which, vat its lower end, is pivotally connected to lugs 46 of the pressure plate, and atitsupper end engages an eccentric 47 forming an integral part of a shaft 48 extending transversely o'E the housing` 19 and journalled in the ` side members 20, 20 of the same. A handle 49 is provided as a means for manually turning the shaft to effect, through the eccentric 47 and the various interposed instrumentalities above described, the actuation lof the toggle mechanism-win relatively shifting the pinch: Y

members 30, `31 -to clamp or release the Inuntins or mullions of the window sash structure.

when adjustment of the .Species ,0f the 'm Lacasse-1 pinch elements inf-the clamped position be more than a few hundredths of an inch.

In order that the perimetrical or side rails of the window sash may be rigidly held in proper relative position with respect to the muntins or iniillions being riveted, I have provided each 0f the clamping devices with auxiliary clamping means consisting of one or more grip fingers 54-which are pivoted to integral lugs 55of the cross bar 21 of housing 19. The upper ends of the grip fingers 54- are adjustably pivoted-to the rods 56 of ecceiitrics 57 which, together with the ec-Y centric 47 previously referred toform integral parts of .the` shaft 48.V l By this construction, it will be seen that both the main and the auxiliary clamping means may-be simultaneously actuated' by movement of the handle 49. As shown in Fig. III, the side rail of the sash frame is clamped between the forward ends of ther housing. side members 2O and the lower ends of the grip fingers 54.

Referring now to the modifications of Figs.

XI andXII, the bracket by which the pneumatic rivetingtool 7 is secured-to its slide4 carriage 6 takes a somewhat different form than in the .first described instance. `.In this case, this bracket assumes the shape of. a

yoke 60 vwhich straddles the barrel off the tool, sufficient leeway Ybeingallowed beneath the laterally turned. feet 6l, 61 of'the bracket, so that the tool may be rigidly clamped in position.. This form ofbracket y differs also from the preceding, in that its upstanding klug 62 is bifurcated as at 63 to receivethe endof the extension bar 18 vby which the clamping device 7 is attachedto the tool.`

In Fig. XIII, Ihavey shown a modified forni. of clamping device which is identical with the forni first described, except that in this instance. the .iiitei'iiiediate or `common pivot rods 39 ofthe toggle link `groups are directly suspended from the 'pressure plate 43, by iiicans of links withoutthe interposition of sustaining-` bai's, such as, Vare showniat 42-in Fig. VII. `Inall other yrespects, the construction .and operation of the formfshown in Fig.' XIII is the saine as XIV, have already understood.

Referring, lastly, to n showna clamping' device inwhichbut one group or setfof toggle links is employed.

Here the Vpinch element 30 cooperatesv directly with one fof theside members 2O of the housing frame 19,- actuation of the toggle mechanism being'effected in a manner similar to that explained in'connection with theiirst described embodiment.

Vhile I have shown and described my invention as particularly applicable to assembling of window vsash structures, I do not wish to be necessarily restricted to such adaptation alone, since it may obviously be employed in other arts with advantages similar to'these herein pointed out.
