MACHINE FOR ASSEMBLING WINDOW -FRAMES.

SPECIFIGATIDN forming part of Letters Patent No. 745,299, dated November 24,1903- I Application filed July 21, 1902.

To aZZ whom it may concern:

Be it known that I, HENRY COLLIER SMITH, of Boston, in the county of Sufiolk and State of Massachusetts, have invented a new and useful Improvement in Machines for Assembling Window-Frames and the Like, of which the following is a specification.

The parts of a sheet-metal window-frame must be assembled with absolute accuracy, for the reason that such window-frames are ordinarily brazed at the joints, and it is practically impossible to correct any inaccuracy in construction after the frames are once set up. For this purpose I have constructed an assembling-machine which while it is especially adapted for assembling the parts of window-frames may be used with but slight modifications for assembling parts of otherdevices which are to be joined at an angle to each other, whether such devices are quadrilateral or not.

My invention will be understood by reference to the drawings, in which- Figure 1 is a plan of aportion of the upper part of the track-ring, being broken away. Fig. 2 isa Side elevation, the frame-clamps being omitted. Fig. 2 is also a side elevation taken at right angles to Fig. 2. Fig. 3 is' a section on line 3 3 of Fig. 4, Fig. 4 being a detail of the side clamp. Fig. 5 is a section on line 5 5 of Fig. 6, Fig. 6 being a detail of the head-clamp. Fig. 7 is a section on line 7 7 of Fig. 8, Fig. 8 being a detail of the sillclamp. Fig. 9 is an enlarged view of the central adjusting-clamp, Fig. 10 being a section on line 10 10 of Fig. 9. Fig. 11 is an enlarged section on line 11 11 of Fig. 2. Fig. 12 is a section on line 12 12 of Fig. 1 enlarged. Fig. 13 is an enlarged view of the centrally-adjustedclamp in vertical cross-section. Fig. 14 is a view of amodification of the central adjusting-clamp, Fig. 15 being a section on line 15 15 of Fig. 14. Figs. 16 and 17 are front and side views, respectively, ofa modification embodying my invention, Fig. 18 being a section on line 18-18 of Fig. 16.

I shall describe my invention as embodied in a machine for assembling four-sided sheet- 7 metal window-frames, as it is for this purpose Serial No. 116,409. (No model.)

the invention was primarily made, and, as shown in the drawings, the parts of. themachine by means of which the several portions of the window-frame are held are capable not only of a movement about a vertical axis, but also about a horizontal axis. For this purpose these parts are mounted in a manner below described upon a platform A, having a central pin a, which, as shown, seatsinto the socket a in the floor. (See Fig. 2.) The platform as constructed consists of a rectangular skeleton suitably braced by means of braces a and provided with casters (1 attached to its under side, so as to support it and allow it to be turned in either direction with the least possible friction. B is a stationary ring mounted on this platform A, being attached thereto byangie-irons a Braces B run from blocks 5 at the corners of the platform to the ring at opposite sides near the extremities of its horizontal diameter. It will thus be seen that the ring as a whole is capable of rotation about a vertical axis with the platform A. The ring is preferably T- shaped in cross-section, (see Fig. 11,) having bearing-surfaces b b on its inner side and opposing bearing-surfaces b 12 upon its outer side.

Within the ringB is supported the assembling mechanism proper in such a manner that it may be rotated about a horizontal axis. For this purpose I prefer to provide a'carriage comprising a cross-bar C, a central support D, and two braces D D, connecting the extremities of the cross-bar O with the extremity of the central support D, the whole forming a support for the assembling-frame. The cross-bar O has at each end and the sup: port D has at its outer end a forked piece 0, fastened thereto by set-screws c. This forked piece carries in both forks a shaft 0, headed at one end 0 and having a cotter-pin c at its other end to hold it in place. Upon this shaft is carried a spool-shaped roll 0 having treads which run on the bearing-surfaces b of the ring B and flanges c which hold it from lateral movement with relation thereto. The extremity of each fork carries a stud on which is a roll 0 which runs on one of the bearing-surfaces b of the ring 13. This crossbar 0 has a socket 0 near its middle, through which the central support D passes. The upper end of the central support D is reduced in size, as at d, so that a shoulder is formed on which the assembling frame rests. A loop-frame c connects the two parts of the cross-bar G and carries a socket to receive the upper end of the reduced port-ion cl of the central support D. Between the sockets and c is supported the assembling-frame now to be described.

E F are two castings, each of which comprises two pairs of sockets connected by a bar. The sockets of the castingE are marked E and those of the castingF are marked F. The bars referred to are marked E and F respectively, and each is provided with a hole E F, through which passes the part cl of the central support D. Washers e, e, and f on (I separate these various parts. These sockets E F are for the purpose of holding the free ends of beams G, which beams extend from the center of the assembling-frame to its four corners, where each beam is received in a socket H, attached to one of the cornerpieces K in the manner below described. Each beam G is clamped in its various sockets preferably by means like that shown in Fig. 10, which is a cross-section of one of the sockets F and shows the wooden braces G in position therein.

F is a clam ping-shoe held against the brace G by means of a set-screw f passing through an oblique portion f of the socket-piece F and engaging the corresponding oblique portion f of the shoe F. By this means the turning of the screw f serves not only to clamp the brace G horizontally, but also vertically. Each socket-piece E is provided with similar clamping means.

The sockets H, which serve to receive the outer ends of the braces G, may be provided with an ordinary set-screw or with the clamping mechanism above described by means of which to clamp the end of the brace G into the said socket. The purpose of this central socket arrangement is to enable the assembling-frame to be adjusted for window-frames of different sizes.

The corner'pieces of the machine are all made alike; but, as will be seen below, two of them are used in reverse position from the other two. They are supported by the braces G, extending from the center of the frame, and also by the side rods J J and the end rods J J these rods extending from corner to corner, giving to the frame its general rectangular character.

It will be seen that the side rods are at a slightangle with the horizontal. This is rendered necessary by reason of the reversal of the corner-pieces above referred to, which brings the opening J of one corner-piece near the top of one casting and near the bottom of the next casting. One of these corner-pieces is shown detached in Fig. 12. Each com prises a right-angled. casting'K, having two bearing-surfaces 7a, to which the frame-clamps are attached, being also provided with a slotted portion 71;, in which sits an eye It, projecting from the socket H. A bolt h, provided witha suitable set-nut 72, passes down into the corner-piece K and through the eye It to hold the socketand corner-piece together. Through this opening J in each piece passes one end of one of the rods J J, which rod is clamped in place by means of a set-screwj. One of these openings is shown in Fig. 12. Each corner piece also has a sleeve J to receive the end of one of the end rods J J (See Fig. 1.) The rods J J are held in their sleeves bya set-screwj. Each side rod is supported on the carriage O by a clamp J To each bearing-surface 7c of one of these corner-pieces K is attached by bolts a frame-clamp constructed to hold a portion of the frame to be assembled. These clamps differ somewhat in structure, accordiug to the shape of that portion of the frame which each is to hold; but each is provided with means for attachment to a corner-piece, comprising an arm K, having a bearing-surface K These clamps are shown in detail in Figs. 3 to 8, inclusive. The side clamps are shown in Figs. 3 and aand are constructed as follows: The side clamps are lettered L and L. They are four in number, and the clamp portion of each is like the clamp por tion of all the others. They differ only in that the arm K projects from one side of the clamp L and from the opposite side of the clamp L. The clamp shown in Figs. 3 and 4 is one of the clamps L. The fixed member L has a skeleton face l with suitable projections Z thereon, adapted to receiveportions of the inner face of the side rails of the window-frame, and it has on its farther side a grooved surface Z to receive the adjustable locking member Z of the movable member. The movable member of the clamp comprises a clamping-piece 1, which is fork-shaped, the two ends Z of the fork being shaped to engage the opposite surface of that portion of the sash-frame which bears against the surface Z of the clamp. This clam ping-piece is held in place by means of a, heavy bowspring Z, pivoted to it at U, the spring being of an irregular bow shape and having an eye at its free end, through which passes the locking member Z which is threaded and has upon it a set-nut Z the inner end of this locking member Z being adapted to slide in the groove Z in the part L of the clamp and being adapted to be set up to adjust the spring to frames of varying thicknesses. Where the shape of the frame requires it, the fixed member L" may be compound in character, as indicated in Figs. 3 and 4, where a sleeve L extends rearward from its face and slides on a stud L whichis connected to the arm K. The sleeve is slotted, as at L, and a pin L projecting from the stud L through the slot L limits the movement of lOO the sleeve L The clamps shown in Figs. 5 and 6 are adapted to receive the head of the window-frame and are those clamps lettered M in Fig. 1. They are also alike except as their attaching member K in one case projects from one side of the clamp member and .in the other case from the opposite side of the clamp member, this being a matter of convenience, however. These head-clamps have parts corresponding to parts of the side clamps-namely, a skeleton face m, shaped to conform to the head-rail of the sash, a grooved surface m lockin g member m forkshaped clamping-piece m, ends of the fork m and a heavy spring m pivoted at m the locking member wa being threaded, as described, and having a set-nut m The sillclamps are lettered N and are similar in character to the other clamps, comprising the following parts: the skeleton face 12, projections n, grooved surface n locking member 02 clamping-piece n ends of the fork of, heavy spring a pivoted at n the locking member being threaded, as before, and having a setnut 12 In each of these views thewindowframe is shown in dotted lines, the side rails being lettered P, the head-rail being lettered P, and the sill P and with each of these clamps it will be noted that when the frame is to be released the bow-springs Z m n are all turned about their pivots Z m n sufficiently far to disengage the locking members from their grooves Z m n, and each clamp is thereby loosened from its engagement with the other clamp member, thus releasing the frame, which thereafter rests only upon the top wall of the projections Z. The face of the side clamps must now be pushed back to withdraw the projections Z from between the projections on the side rail of the frame, and the frame may then be lifted from the machine and the parts of another frame assembled by reversing the operations. It is evident that the faces of these clamp members may be altered to suit differing shapes of window-frames.

An important feature of this invention is the means for adjusting the assembling-frame to frames of different sizes. To make this adjustment with the apparatus above described, the set-screws f are loosened and also all the screwsjj, thus allowing the corner-pieces to slide upon the rods J J J J and at the same time the braces G to adjust themselves within their sockets E When the proper adjustment has been reached, the

set-screws are again set in place and the machine is ready to take a frame of larger or smaller size, as the case may be. It is evident, however, that this adjustment can only be had within certain rather restricted limits. If a further adjustment is needed, other rods of differentlength may be substituted for the rods J J J J I have shown in Fig. it another means for adjusting the braces G, each brace in this case being provided with a rack g, the racks of two adjacent braces facing each other and all these racks engaging a pinion g, adapted to turn on the upper end of the rod D and having a square projection g to receive a wrench or key by which the parts may be adjusted when the necessary clamp-screwsf have been loosened. As an additional precaution, in this case I provide sleeves 9 connected by links 9 with the clamps E F, these sleeves sliding upon the cross-rod O and being held in place thereon by set-screws g I have shown in Figs. 16, 17, and 18 another means embodying my invention for supporting the assembling-frame. This means comprises a standard Q, from the top of which projects laterally an arm Q, carryinga socket R is a ring which turns in bearings formed by the segments R R These segments are bolted together, and the ring is provided with flanges r, by which it and the segments R R are kept in proper relation. The segment R carries on its under side a socket R The passage in this socket is adapted to register with the passage in the socket Q and the two are attached together by means of a driven pin g, which fits into both sockets. The ring R has two sockets r, diametrically opposite each other, in which is supported a rod d, which has all the functions of the portion d of the central support D shown in connection with the main embodiment of my invention, and between the two sockets 'r are intended to be supported the central clamping mechanisms E F of the assemblingframe, the rectangular'portions of the frame and their corner-pieces being located outside of the periphery. of the seg-- ments R R. I

It is evident that this invention may be embodied in other ways, its main peculiarity being that an absolutely rectangular assembling-frame is supported not only to turn upon a vertical axis, but also upon a horizontal axis, so that all portions and all sides of the frame may be presented to the operator at a convenient place to be worked upon. It is also evident, however, that in the modification shown in Figs. 16 and 17 the frame can only be turned about its horizontal axis through an angle of ninety degrees, as otherwise it will strike the standard Q, and it is also evident that its horizontal rotation about its vertical axis is also limited by reason of the engagement of parts of the assembling frame with the ring, which is not rotatable about a vertical axis.
