No. 83,537 10 Claims. (Cl. Q9-208) My invention relates to a window assembly machine and has particular reference 'to an assembly machine by means of which side and end rails are applied and secured to a gla-ss pane thereby forming a frame on the four edgesl of the glass pane which, is secured together at the corners, thereby form-ing a complete window for use in various combinations of frames and windows particularly for use in curtain wall construction and various other places where windows are formed for u-se in various types of construction.

Another object of my invention is the provision of a -machine which is entirely automatic in its operation, requiring only the feeding of the glass panes into the machine by an operator, the placing of `side and end frame members `and the screws for holding them in position in the automatic screw insertion machine, and -the removal of the nished sash from the machine after the frame members have been applied to the glass pane thereby requiring a minimum number of machine operators to do the work which heretofore has been completely performed by hand opera-tions.

Another and further object of my invention is the provision of a machine for applying a frame to a pane of glass thereby providing a Window combin-a-tion with a minimum of time and efont in operations which are almost entirely automatic, thereby materially reducing cost of production of such windows.

Another and further object of my invention is the provision of a machine for making window sash for use particularly in buildings of the curtain wall type, for storm windows, and in many other types of windows where the sash portions are both movably mounted and also sometimes removably mounted in window frames and comprises a combination of a conveyor belt, a squaring or positioning apparatus for the glass pane and frame applying and fastening means and the moving of 'the cornpleted sash to the discharge end of the machine where the completed window sash is removed from .the machine.

175 and 176 mounted thereon with pistons 177 and 17S in the cylinders and 176, this frame and lifting cylinders being mounted towards the left side of the machine looking toward the discharge end.

A pair of

smaller lift cylinders

179 and 18

% having pistons

181 and 182 mounted therein are secured to the sides of the

cylinders

175 and 176 respectively, these cylinders 179 and 135.! being comparatively small with the

pistons

181 and 182 therein being somewhat short so as to lift the sheet `of glass 37 a sho-rt distance in a preliminary operation hereinafter described.

A frame similar' to the one hereinabove described is provided at the opposite side of the machine and cornprises a pair of support bars 183 and 184 to which a plate 135 is Welded, which plate -185 has a pair of lifting

cylinders

186 and 187 mounted thereon having pistons 13S and 189 mounted therein with smaller air cylinders 191i and 191 being mounted on the

cylinders

186 and 187 with

pistons

192 and 193 therein, all of said lifting cylinders being arranged in somewhat rectangular form so that as the pistons are forced out of the cylinders by compressed air the glass pane is lifted upward to predetermined levels for purposes hereinafter described.

A pair of

plates

194 and 195 are provided on opposite sides of the machine which are welded to the cross bars 28C and 28d and have

cylinders

196 and 197 thereon having

pistons

198 and 199 therein which are mounted slightly above the lifting cylinders and below the frame applying members in opposed relation with each other, and the plate 195 has

cylinders

197, 197 thereon with

pistons

199, 199 therein which are opposed to the pistons 19S, 198. Another pair of plates 290 and 201 are provided whioh are welded to the cross bars 28C and 28d and have horizontal cylinders 262 and 203- mounted thereon, these cylinders having pistons 204 and 2195 mounted therein which cooperate with the

pistons

198 and 199 to properly align and square up the sheet of glass 37 before it is lifted into position for the applicat-ion of the frame members to the side and ends of the glass pane 37.

The operation of the machine consists of three major steps in the complete application of the end and side sash members to the pane of glass 37-rst, the squaring operation of the pane of glass prior to its being lifted to the level of the sash applying members; second, the application of the sash members to the glass pane; and third, the fastening together of the frame members at the corners thereof by the application of screws. These operations are automatically performed with the transporting of the glass pane through the various stages, also being automatic, with a sufficient time lag for performance of the machine of each stage of operation. The only manual handling is the placing of a glass pane on the belts at the receiving end of the machine and the removal and inspection of the pane at the `discharge end of the machine, and the placing of the sash members and screws into proper places in the machine.

The operation of the machine preferably requires four attendants, one at the receiving end of the machine who places the glass panes upon the belts. The glass panes have had the molding 38 applied to the edges of the pane by hand and are placed flatwise on the belts with their long diameters paralleled to the longitudinal axis of the machine. Two other operators are required-one on each side of the machine adjacent the frame-applying member who, as soon as one sash has the frame applied thereto and is deposited upon the belts, places the

frame sections

41, 42, 43, and 44 into the frame holders on the movable carriages-usually one operator placing a side frame into one set of side frame holders S5, S and the end frame Amembers into the holders 141, 141 while the other operator places a side frame member such as 43 into the

holders

64, 64 and an end frame into the

holder

160, 160 ready to be applied to the sash at the appropriate time. The fourth operator is located at the discharge end of the machine to remove and inspect the completed sash from the belts.

In the operation of the machine as shown in FGS. 8 and 9 of the drawings which shows wiring connections and some of the parts generally, and three current supply lines are shown from a transformer T, L1 being a high voltage line for the operation of the main motor 33 while L2 and L3 are control and hold circuits of the usual standard 11S-120 volt lines.

When the operator desires to start the operation of the machine, he closes the starting switch S-1B which closes switch R0 through S-2 which starts the motor 33 thereby causing the

conveyor belts

27, 27 to travel over the end rollers and 26 and which convey the sheets of glass through the machine. The closing of the starting switch S-1B also sets up R-6, R-S and R-9, the control circuits, and also closes the circuit C-1 to a main air compressor.

As the glass pane 37 moves through the machine, the pane engages a switch arm 206 opening S-2, also opening R-8 and R 9 stopping the

conveyor belts

34, 34 and retracting the guide or squaring

pistons

19S, 199 and 204, 205 which action sets up R-1 thereby engaging V-1 admitting air to cylinders 179, 180, -192 and 193 `forcing the

pistons

181, 152, 192 and 193 upward against the under side of the glass pane 37 and raising the pane 37 of the

belts

27, 27 about two inches to the level of the squaring

pistons

198, 199, 204 and 205. When the glass pane 37 is lifted initially, S4 closes energizing V-2 which actuates the

pistons

198, 199, 204 and 2115 squaring the glass pane in position for application of the frame members, but at a level below such application, by air pressure on the

pistons

198, 199, 204 and 205, which is simultaneously released on all pistons so the glass frame 37 is maintained in proper position on the

lift pistons

1181, 182, 192 and 193. At the end of the squaring operation, T-'1 times out breaking contact with and de-energizing V-Z causing retraction of the squaring

pistons

198, 199, 204 and 205. During the retraction, S-5 closes momentarily which closes R-2 thereby admitting compressed air to cylinders 175-1'76, 186 and 137 raising the glass pane 37 from the

pistons

181, 182, 192 and 193 to the proper level for the application of the frame members to the sides and ends of the glass pane. With the glass pane fully raised, S-7 closes setting up R-3 which in turn energides V-4 which admits are to the front end of cylinder 168 exerting a pull on the arm 166 rotating the shaft 146 in a clockwise direction and moving the

bars

144 and 163 towards each other thereby moving the carriages 134 and 153 inward. Prior to this movement and while the carriages 134 and 153 are stationary,

end sash members

41 and 42 have been placed in position by the operators at the sides of the machine in lthe

sash holding members

141, 141 and 160, 160, and as the carriages 134 and 153 move inward, the

sash members

41 and 42 are irmly applied to the ends of the glass pane over the molding previously applied thereto. The

sash members

41 and 42 are pressed tightly into position over the edges of the glass pane at each end thereof by the pressure on the piston in the cylinder 168 with resistance aiorded by the glass ypane and as the sash members are rmly placed in position, this resistance equals the pressure of the air cylinder and the carriages 134 and 153 are held in stationary position.

With the

end sash members

41 and 42 in place, S-8 closes thereby setting up R-4 which engages V-S opening valve to front end of cylinder 91 thereby exerting a pulling force in the piston 93 thereby rotating the crank arm 162 in a clockwise direction pulling the

carriages

53 and 59 inward.

Side sash members

41 and 42 have previouslybeen inserted into the

guides

64, 64 and 85, on the carriages 58 and 59 and these frame members are carried and applied under pressure to the sides of the glass pane.

With the side sash members in place, S-9 closes setting up R-S energizing V-6, thereby admitting pressure to the sash member molding ejects 65, 65 and also energizing T-3 timing motor and energizing V-7 and V-7A thereby simultaneously starting the four screw driver elements which turn the

screws

46, 46 previously manually inserted in the screw holder tips 72 through the holes 4S, 4S formed in the ends of the

side sash members

43, 44 and into the channels 47, 47 formed in the

end sash members

41 and 43.

The time limit switch T-3 is set for approximately four seconds for the holding of the glass pane in place on the

pistons

177, 178 and 181 and 182 and to allow the screw inserting mechanism to function properly.

With the

screws

46, 46 almost seated, the limit switches S-14 through S-17 close energizing T-2 allowing proper time delay for iinal seating of screws in place. On timing out S-13 trips, knocking down R-6 and R-3 and setting up R-7 admitting compressed air to the rear end of cylinder 168 exerting a thrust on the crank 166 which rotates the shaft 146 in a counter-clockwise direction thereby retracting the end carriages 151i and 153 and also retracting the side carriages 58 and 59 and deenergizing motors in timers T-2 and T-3. Upon the end frames being retracted, S-11 opens knocking down R-4, de-energiring V-5, retracting side carriages 58 and 59, also 78 and 79, also opening S-6, knocking down R-l, R-2 and R-S, de-energizing V-1, V-3 and V-6, and resetting S-4 causing retraction of both sets of raising cylinders thereby lowering framed pane of glass onto the

belts

27, 27.

With the lifting pistons fully retracted, S-12 closes setting up 1?.-6 for a new cycle. Also, S-1A closes setting up R-0 restarting motor 33 which starts belts 27 moving framed window sash toward discharge end of the machine. Also, as the finished window approaches the

belts

27, 27, switches 2-A and S-lB are tripped by the

switch arms

206, 207 rendering S-2 inoperative until the nished window clears these switches, when they set up again for the next cycle of operation. As another glass pane reaches the framing area on the belts 27, the switch 2116 trips starting a new cycle of framing, stopping the belts when a iinished window at the discharge end of the machine can be inspected and removed by the operator there stationed and a new pane placed on the belts ready to be moved into the framing area at the appropriate time.

It will be understood that the machine is entirely automatic in its operation when attended as hereinabove described, and if a cycle is missed, the machine can be stopped by opening the emergency switch and any broken or defective part of the window removed and the machine restarted.

While I have described more or less precisely the method employed and the apparatus used therewith, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing yfrom the spirit or scope of my invention.
