Specification of Letters Patent.

Patented Oct. 7, 1919.

1 0 all whom it may concern:

Be it known that I, LOUIS B. GIRABD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented anew and useful lVindow-Shade Mounter, of which the following is a specification.

This invention relates to means for mounting window shades on their rollers, and the main object of the invention is to provide a machine whereby the fastening of the shade on the roller may be effected quickly, easily and with great accuracy and security.

Another object of the invention is to provide improved die mechanism for forming and driving fasteners for shades or for other articles.

The accompanying drawings illustrate means embodying my invention and referring thereto.

The working parts of the machine are preferably mounted in a suitable frame comprising a base or table 1, and standards'2 and 3 mounted thereon. Standards 2 and 3 may be provided with forward extensions 4 and 5 from their lower parts, serving to support brackets 6 and 7 which are mounted on the respective extensions 4 and 5, so as to be adjustable to or from the standards 2 and 3, said brackets for example, being slidable on parts 4 and 5 and being clampedthereto by cap screws 8, passing through slots 9 in said brackets.

A shaft 11, herein called the pick up shaft, extends through bearings 12 and 13 on the respective brackets 6 and 7, and is provided with an operating arm or handle 15 mounted on a sleeve 16 which is mounted on shaft 11 by a key or spline 17 engaging in a lon- .gitudinal groove 11', in said shaft, and is provided with an arm 18 having at its rear end, a pick up or roller engaging device 19, formed preferably as a head on a spindle 20 mounted to turn in a bearing 21 on arm 18, said head having a conical socket or recess 19 adapted to receive the pin at one end of the shade roller.

' A driving chuck 22 is provided for engaging the other end of the roller, said chuck being mounted on a mandrel 23, mounted to turn in bearings 24 and 24 on a chuck carrier 25, which is mounted on pick up shaft 11 so as to turn therewith. Arubber friction ring 22 is secured in chuck 22 to en- 30 on the shaft of amotor 32, which may be an electric incre ses 28 being loose and '1, to form a guide or way for a roller-support or bed member 39; which is formed preferably of channel iron with-the flanges 39 there'of extending upwardly so as to form guards for the roller, whereby the rolleris retained in proper positibm-flas indicated in Fig; 9. Said member 39 is mounted on suitable means for adjusting it vertically,rbeing provided forexample with wedges 4O secured to the bottom thereof and adapted to slide on studs 41 extending between and secured to the bars38 and 38,

so that by longitudinal movement of the member 39-it may be caused to Il1 OV6 vertically; and thereby raise and lower the roller to bring it to proper position with relation to the stapling means. Such longitudinal movement of themember 39 may be effected by a lever 44, pivote d at 45 to the base of standard 3 and connected to member 39 by a pin 46 on member 39 engaging in a slot 47in lever 44. Said lever is also provided with a slot 48 adapted to engage any one of a number of studs 49 which are mounted on a segment 50 carried by the bracket 7 said segment being provided with holes 52 to receive said studs so as to provide for shifting of said studs when required for odd sizes, it being understood that the position of the studs on segment 50 corresponds to the different adjustments of lever 44 for the standard sizes of roller.

Lever 44 is haotinted with sufli'cient flexi bility to permit it to be forced over anyone of the studs in ehangingit's adjustment.

A shaft 54 .is mounted in the standards 2 and 3 so as-to be held in fixed position at i the rear of the roller supporting meansahd a die mechanism for forming. .-and driving staples is mounted on said shaft so as to be movable longitudinally and vertically said mechanism being carried by an arm 55 having its hub 55 clamped on a sleeve 53 mountedto turn 'on shaft 54'and having a key 56 engaged i-na longitudinal groove or key way 57 in said shaft said groove being of sufiicientl-y greater width than the key 56 to permit of limited rotat'ive movement of the ar'm55 on the shaft, said arm 55 is also provided with a projection, preferably 7 formed a screw soiacljustably' mounted.

thereon and zwlapted to engage a suitable fixed stop, such as bar 61, on table 1, at the spring'contannn-g end of the roller to arrest the downward movement of the die means as hereinafter described.

A die head 58 is mounted rigidly on the arm 55, andis provided with a vertical way 63, with a side plate 64 closing said way at one side,-and with a removable bottom plate 65 which constitutes the female die, being formed with an aperture or die hole 66, whose rear wall 66 conforms to the shape ofthe rear and front edges of the staple or fastener to be cut. The front wall 67 of the hole 66 is formed with a notch or recess 68 to receive the point at the forward end of the staple strip; Plate 65 is also formed with a channel'or way 69 formed for example ma removable or replaceable die "members 73 for recelvmg and guiding the staple strip, I the portion of the plate directlyatthe rear of the cutting edge or wall-66 inc-lining slightly downward fronr the bottom of said channel and forming a vcontinuation thereof, and being somewhat below the top of the front wall 67 of hole 66, so that the staple strip fed forward through channel 69 will be arrested by its forward end striking said front wall. A

cutting and-forming punch or male die 70 is mounted to slide vertically in way 63 and a severing, forming and driving punch or male die 71 is mounted to slide in a vertical slot or way 72 in punch 70. The bottoms of the respective punches 70' and 71 are vconcavely curved as shown at 7 0 and 71,

to approximately conform to the cylindrical surface of the shade roller, and the bottom of the fixed dieplate 65 is also'similarly curved as shown at 65'.

The die means aforesaid are operated by a lever 7 5, pivoted at 76 to arm v55 and.pro vided with a handle 77. A pair of links 78 are pivoted at 79 to said lever and at 80 to a bell crank 81 which is pivoted at 8.3

to arm 55 and at 84 to a pair of links 85 whose lower ends are pivoted at 86 to a lever 87 which is pivotally mounted at 88 on a stud 89, and is connected to the main cutting and forming punch 7 O by, a pair of links 90, pivoted at their upper ends by pivot 91 to lever 87 and at-their lower ends by pivot 92 toan ear 93 onthe upper-end of punch .70. Stud 89 is vertically adjustable v on arm 55 being formed for example as a bolt passing through a verticalslot 94 in said arm and'fastened by "its nut 95. The

suppleinentary punch 71 is connected vdi rectly to lever 75 by a pair vof links 96 ipivoted at 97 and 98 respectively to the lever and to an car 99 on the upper end of said punch The staple strip, indicated at 100 is wound on. a reel 101, which is rotatably mounted en a 109. on ark-n 104 extend rigidly fresh. the hub 55 which carries arm 55, the arms 55 and 104 constituting in effect a single cross arm. Said reel is engaged by a tension spring 105 mounted on arm 104 and adjusted by means of a screw, to give the required tension for the feed. The outer end of the strip 100 is passed under a guiding pin 111, through a gripping device on a feeding lever 108 pivoted at 109 to arm 55 and then through a gripping device on a retaining device 110 fixed on arm 55. Lever 108 is operated by a projection 112 thereof which is engaged by the operating lever 75 at a certain part of its stroke, to swing the lever 108 to-the rear, and a spring 113 is connected to said lever 108 and to arm 55 to return said lever to normal position. The gripping device on lever 108 may comprise a jaw 114 formed with a channel 115 through which the strip 100 passes, and a pawl 116'pivoted at 117 to said lever and forced into engagement with the strip by a spring 118. The retaining device 110 is formed as a jaw similar to jaw 114 and cooperates with a pawl 121 similar to pawl 116 and operated by a spring 122.

A shade supporting platform 125 is provided on table 1, inclining upwardly and forwardly to about the level of the top of the shade roller support 39. A gage bar 126 is also provided on table 1, extending rearwardly from the roller support to form a side gage for the pile of shades on the table.

WVhile any suitable form of die means may be used with the above described mounting apparatus I prefer to use the form shown in the drawing which is adapted to form and drive a fastener from a plain strip of metal at each feeding operation of the strip, and which reduces to a minimum the amount of material required for each staple or fastener. In this construction the female member of the die means is provided at the rear wall 66 of die hole 66, with a forwardly projecting die portion 130 having forwardly converging vertical side walls 131 terminating in transversely extending shoulders 132, anda forward extension 133 is provided between these shoulders, having forwardly converging vertical side walls 134- forming a'wedge shaped die portion corresponding in outline to thepoint to be formed at the front of the fastener, theapex of this wedge shaped die portionbeing directly rearward from the apex of the V- shaped notch 68 infthe front wall of the die hole, and spaced therefrom a distance corresponding to the width of the fastener from front to back. This projection 130 may be formed on the replaceable member 73. The main punch 7 0 is formed with-two punch portions 136 each formed at its outer face to fit the side walls of the die hole 66 and eaeh provided. with an inner wall per tion 137 extending obliquely inward and forward so as to slide past and conform to the forwardly converging side wall portions 131 of the die projection 130. A web portion 138 connects the main punch member 7 0 with a forward prong bender 139 formed as a flange on said web and fitting against the front and side walls of the way 63 and of the die hole 66. The vertical channel or way 7 2 for guiding the punch 71 is formed by the front wall of punch 70, rear wall of part 139, the web portion 138 connecting side walls and the inner face of the removable side plate 64 of the die head. The punch 71 is provided in its rear face with a vertical V-groove 135 adapted to cooperate with the wedge-shaped die portion 134, and with a transversely extending wall 74 at each side of said groove.

The'operation is as follows:

A stack of shade cloths indicated at 127 in Fig. 2, cut to the proper length and width is placed on the table 1', the front ed of said cloths being brought into proper parallelism with the roller support b-y abutment of one side against the shadegage 126. The die mechanism carried by arm 55 is moved far enough to one side by means of handle 77 to be out of the way and a shade roller indicated at 128 in Fig. 9 is placed 1 on the roller support 39 so that the end containing the spring engages chuck 22, said support having been previously adjusted as above described so that the pin at this end of the roller will enter the recess in chuck The top shade cloth is then drawn forward over the inclined platform 125 until its forward edge portion is over the center of the roller in position for mounting, the said platform enabling the shade to lie flat on the roller. Then the die mechanism is moved by handle 77 to position for driving the first staple, the lever 7 5 being held at such elevation as to hold the key 56 in the sleeve out of engagement with both the upper and lower edges of the groove 57 in shaft 54 so that the arm 55 andthe die means carried thereby may be readily moved to the required position. Handle 77 is then lowered until the bottom plate 65 of the die head strikes the shade roller, the concave'portion 65' of such head then resting on the roller and arresting further downward movement ing device 110 and through channel inthe bottom member 65 of the die means, and

over the die projection 130 at the rear of I the die hole 66, the forward end of the strip which is pointed as shown at 142 from the last operation, being in engagement with the front wall of the die hole, in such manner that the point or prong 142 enters notch 68 in'said front wall and thereby accurately centers the strip and at the same time arrests the strip in proper position for cutting off of the next staple. The downward movement of the lever 75 being continued, it moves the punch 7 0 downward through the action of bent links '7 8, bell crank 81, links 85,.1ever 87 and links 9 0,and at the same time it moves the punch 71 downward directly through the action of links 95. When said punches have been moved sufficiently in this operation to bring them into contact with the staple strip, the die parts occupy the positions shown'in Fig. 4. As both the main punch portions 136 are rounded at bottom as shown at 7 0, they touch the staple strip only at their rear edges, and the inner faces of these punch portions diverge rearwardly and extend beyond the edges of the staple strip, sothat they cut the strip by a shearing cut beginning at each side and cutting obliquely inward and forward toward the middle of the strip, thus forming prongs indicated at 141 in Fig. 18, which are widest at their forward portions and taper to sharp points at their rear ends. The oblique curvature of the bottom faces 7 0' of the punch portions 136 also starts the bending down or forming action on the prongs so cut, this action being completed by the vertical front faces of said punch portions, as they pass on down through the. strip, thereby bringing said prongs to vertical position, as shown in Figs. 5 and 18. At the same time the prong bender 139. at the front of the mainpunch engages the point or tip 142 at the forward end of the staple strip and bends it down to form a vertical prong, as shown in Fig. 5, the forward extension 133 of the female die serving as a support for the part of the strip directly at the rear of this tip portion, during this operation. By this time the lower armof bell crank 78 has moved nearly to dead center position with respect to the pivotal connections of links 85 with'the said bell crank and with the lever 87, s'othat further downward movementof lever produces only a slight further movement of the main die or punch, 70. During the above described operation the severing punch 71 has been brought to position with its lower face just above the staple strip, as indicated in Fig.

5. Continued downward movement of lever 75 causes the punch 71 to move on clownward, with thje'result that the transversely extending walls 74 of the saidpunch will cooperate with the transversely extending heulclers 132 1 the forward prejeetien i363 of the female die so as to cut the strip transversely, these cuts indicated at 144 in Fig.

14' extending inwardly fromthe forward ends of the'oblique cuts 145 made by the main punch portions and the obliquely extending walls of the 'V-groove 135, in the punch 70 then cooperating with the corre- .sponding sidewalls 134 of the forward extreme point of the staple. While the punch 71 is thus cuttinga point at that part of the strip between the walls of the vertical groove, the parts of saidpunchat each side of sfaid groove are pressing'the side portions 147 o fthe staple already cut, somewhat downward, and in the further downward movement of punch 71, these side portions of saidrpunch' act to drive the severed staple downward 'so that the prongs 141,142 thereof are driven into the shade roller as shown in Fig. 9. As the staple is thus driven home, the main punch portions follow down somewhat as shown in said figure, so-that' the downwardly extending prongs 141, 142 are laterally supported While they are being driven. The forwardly extending wedge shaped die portion 183 'also'aids in guiding and supporting the staple laterallyin' this driving operation by engagement in the notch 148 formed in therear of the staple. The fact that the bottom "of the driving punch 70 is approximately of' the same curvature as the surface of the shade roller enables the staple to be conformed to such 'punches" 70 and 71 to move upward to strip the dies, the strip 100 being held down by the pinql49. The die mechanism is then moved "toposition for inserting the next fasteners and the operation is repeated,

Then the part of the shade roller is reached ajdjacenttolth'e winding spring for the shade,

lthepi-ni'or projection (50 engages the fixed stop6lfto arrest the downward movement of r the die head, thereby; prevent excessive pressure n the shade roller at this part, which-is weakenedby the bore made for said spring- In the "downward movement of lever 75 it strikes projection 112th lever 108 and were t e 91 b e said means slipping over strip 100 in this movement. As lever 7 5 is moved upward, spring 113 restores level-108 to normal position causing gripping means 116 to feed strip 100 forward until the point 13 engages notch 68 in the front wall of the die hole, thereby bringing the strip to position for cutting and driving the next staple. It will be noted that but one feeding operation is necessary, the staple being wholly cut while the strip is in one position, and being then driven without requiring further advance of the strip.

The staple or fastener made by the operation above described is shown in Figs. 16 to 18 and comprises a downturned front prong,

point o-rtip 142, two rearwardly diverging side portions or arms 147, united at their forward ends by said front prong, and a downturned prong 141' at the rear end of each of said side portions. Each of said side portions is curved so as to be concave on the bottom. v V

This curvature of the top of the staple is due primarily to the bending down of the forward part of the staple strip, by the action of the punch or prong bender 139, the

downward inclination of the top face of the pro ection 66 of thedie member 7 3, P61111113: I

ting this bending, and the curvature of the bottom faces of punch 71 maintaining and completing the bend so formed in the staple top.

hen all the staples required for fastening the shade to the roller have been driven in the manner above described, the handle.

15 is moved to the left, so as to cause pickup 19 to engage one end of the shade roller and causes the latter to be gripped between pick-up '19 and chuck 2:2 and handle 15 is then operated to turn the pick-up shaft 11 and thereby raise chuck 22 and pick-up 19 so as to lift the shade roller off the support 39 and at the same time cause the pulley 27 to engage belt 28 so as to tighten said belt and cause it to rotate the pulle 27 and the chuck 22 connected thereto. The shade roller is thereby rotated so as to wind the shade thereon; the operator pressing the'shade with one hand so as to cause it to wind tightly on the roller. Handle 15 is then moved to the right so as to release the shade roller from the pick-up device .19, and the shade rollerwith the shade 'wound thereon is then removed from the machine which is then ready to receive another roller.

Inasmuch as the die means moves in an are 7 around shaft 5-1, it is necessary to always bring the top of the roller to a certain position, irrespective of the size of the roller, so that it may be in position to properly engage the bottom of the die means and to receive the staple when driven thereby. To adapt the device for any of the usual sizes of rollers, the roller support is adjusted vertically 40, being" adapted to engage studs 41 and support the roller support 39 in any one of several positions. In this case the gaging means described above for lever 44 may be dispensed with, the number and arrangement of the recesses 151 corresponding to the number and arrangement of the studs 49 in the former case.

In case a more accurate and flexible means of adjustment for the roller support is desired, lever 44 may be provided with a downward projection 152 engaging a series of ratchet teeth 153 on a segment 15tcorrespending to the segment 50 in the first-described case. In this case the position of lever 44. must be determined by experiment for each size roller, but on the other hand a wider range of adjustment is provided for.

The shade winding mechanism herein disclosed is not claimed herein, as it forms the subject matter of my divisional application, Ser. No. 154163, filed Mar. 12, 1917, and the particular form of staple herein shown is claimed in my application, Ser. No. 154162, filed Mar. 12, 1917, the same being a division of this application.
