2,738,507 Patented Mar. 20, 1956 In the manufacture of small boxes, particularly the cardboard boxes used by the jewelry industry to package its wares, one of the problems needing solution is a way of rapidly and economically hinging together the box parts. By box parts herein is meant those parts of a box which are customarily hinged together. Each part may be provided with upstanding sides, or one part may be a fiat cover, for example. One step toward solving this problem is provided by the hinge and combination of hinge and box parts which are set forth and claimed in the Lewis Douglas Young United States Patents Nos. 2,648,485 and 2,648,486. The problem with which this invention concerns itself is the machinery used to attach such hinges to the box parts. The invention set forth herein solves the problem in an advantageous way, and particularly so in connection with the type of hinge shown in said patents. (However, the machine of this invention can be advantageously used with other types of hinges using separate rivets.) This invention provides a ma.- chine in which it is possible to load a hinge and its associated box parts on an anvil in a predetermined relationship, and have these elements guided to maintain that relationship while the anvil and box parts are being moved into a fastening or rivet-setting position. The guide means for the box parts is out of the way of the hammer, and the guide for the hinge is automatically moved out of the way during the hammer blow. Thereafter, the anvil with its guides and hinged box is moved back to the original loading position for removal, and

subsequent loading of another set of parts. The hammer may be motor actuated, or foot actuated. Thus, with the machine it is possible to fasten rapidly and economically one or more hinges to the parts of a box.

Referring now to Fig. 1, there is shown a side view of one embodiment of this invention, comprising a base 2 having mounted thereon the upright hollow column 4. Column 4 is formed to provide the horizontally extending cross-arm 6, or, alternatively, cross-arm 6 may be a separate arm attached to the top of column 4. Arm 6 is likewise preferably hollow. (In the above description, the column 4 and arm 6 are indicated as hollow. The purpose of this is to be able to house cermay be used, and the working parts fastened to the out side thereof. Nor is it particular how the column and arm are formed. As shown, they are made, in this in stance, of flat plates fastened together to make a box column or channel.)

Pivotally mounted in arm 6 by means of pivot pin 8 is the cross-lever 10, pin 8 engaging the sides of arm 6. Lever 10 is provided at one end with a pivot bearing 12, and dependent therefrom pivotally is a hammer 14. In this instance, for example, hammer 14 is provided with two upstanding cars 16 which slidably embrace the end of lever 10, the pivot 12 passing through these ears and the lever end, as shown. Hammer 14 is provided with the longitudinal clearance groove 14:: (see Figs. 7 and 8). At the other end of lever 10 another pivot 18 is fastened, and pivotally dependent therefrom is the rod 20. The lower end 22 of rod 29 is provided with a bearing to receive an eccentric 24 on the shaft 28. Rotation of eccentric 24 thus moves arm 20 up and down, which in turn oscillates crosslever 10 to move hammer 14 up and down.

Shaft 28 is journaled in the two bearing plates 26 which are fastened by any conventional means to the sides of the column 4. Fastened to shaft 28, as by the key 30, is the clutch hub 32. Hub 32 is provided with a groove 34 extending around its periphery, which receives therein the end 36 of the clutch release lever 38. Slidably mounted in hub 32 is the clutch pin 40, which is 3 urged to the right (as shown in Fig. 3) by the spring 42 in a direction parallel to the shaft 28. (This right-hand position is shown in Fig. 4.) Entry of the end 36 of lever 38 in groove 34 holds pin 40 in the left-hand position, and pulling the end 36 from the groove allows the pin to move to the right.

Rotatably mounted on shaft 28 is the pulley 42, being held thereto by the washer and bolt assembly 44. Into the inner side of hub 46 of the pulley are fastened two studs 48 which project to the left as shown and are positioned to engage the pin 40 when the latter is in its right-hand position as shown in Fig. 4. Each of studs 48 has its side concavely recessed as shown at 49 to a diameter equal to that of pins 40, thus providing a good hearing or thrust surface for the latter. Pulley 42 is rotated continuously by motor 54 while the machine is being used, but as long as the end 36 of the release lever is in the recess 34, the pin 40 is held back, and pulley 42 rotates freely. Release of pin 40 lets it engage the curved recess 49 of one of the studs 48 which then causes the pulley to rotate the shaft and the eccentric 24 to drive the hammer. Lever 38 is pivoted to the column 4 by means of pin 50, and bears at its extremity the foot plate 52. A motor 54 is provided to rotate pulley 42 by means of belt 56.

Pivotally mounted by one end 58 to base 2 is a second generally upright column or shaft 60, the lower end thereof being pivotally fastened to a flange on base 2 by means of pivot pin 62. So mounted, shaft 60 can occupy two positions, in one of which (full lines) the upper end 64 of the shaft is directly beneath hammer 14, and in the other position (dotted) the end 64 is displaced away from the hammer. A slotted guide member 66 extends from column 4 and slidably receives column 60 in its guide slot 68. Mounted on the upper end of column 60 is the anvil and guide assembly generally indicated by numeral 70, which will now be explained.

Referring first to the anvil and guide for the hinge, anvil 72 is a rectangular block (preferably of metal) mounted on the end of column 60, and held in position thereon by means of a machine screw 74 which passes through a suitably provided hole in the anvil and which screws into the end 64 of the column. To keep the anvil aligned, a channel 76 (see Fig. 7) is provided in the end 64 of the column, and a rib 78 is provided on the bottom surface of the anvil which fits into the channel. The hmge guide comprises the rectangular shaped sleeve 80 which snugly but slidably fits around the anvil 72. Sleeve 80 is supported by two

transverse pins

82 and 84, the ends of which engage the long sides of the sleeve, the pins passing through

elongated slots

86 and 88, respectively, provided in the end 64 of the column 60. The sleeve 80 is thus enabled to slide up and down, and is resiliently biased in the upward direction by means of the compression springs 90 and 92 which are mounted in

holes

94 and 96, respectively (also provided in end 64), to bear against the

pins

82 and 84; slot 86 intersects hole 94 and slot 88 intersects hole 92. The

slots

86 and 88 are so arranged that with the pins 82 and 84 n the uppermost position, the top edge of sleeve 80 proects above the anvil 72 a sufiicient distance to hold thereon a hinge.

Guide bars 98, 100, 102, and 104 are mounted at the upper end 64 of column 60 by having their respective endsunserted, preferably with a squeeze fit, into suitably provided holes in the front and back sides of the column.

Bars

98 and 100 are in alignment, and bars 102 and 104 are also in alignment, the latter pair being below the first pair and also aligned therewith in a vertical plane, As shown, the bars are round for the most part, but have fiats provided thereon for engagement by

set screws

108, 118 and 120 in certain guiding parts.

A stop plate 106 is slidably fitted onto

bars

98 and 102 by means of suitably provided guide holes therethrough, and set screw 108 locks plate 106 in predetermined positron on the bars. Two other plates are provided, indicated by

numerals

110 and 112, and of these plates 110 slides on

bars

98 and 102 by means of suitably provided holes, and is urged toward the anvil by means of compression spring 114. An adjustable stop collar 116 is provided on bar 102 and is locked in place by set screw 118, to limit the motion of plate 110. Plate 112 is slidable on

bars

100 and 104 in the same manner as plate 110, but a set screw 120 is provided to lock it in predetermined position with respect to the anvil. Each of

plates

110 and 112 has formed thereon the outwardly extending

edge fins

122 and 124, these extending in such a way as to give a trapezoidal shape to the plates, that is, narrow at the tops 126 and wide at the bottoms 128 in order to provide side edges which diverge outwardly from top to bottom. These fins also define edge shoulders 127 in which box parts may fit for alignment.

The top of anvil 72 is provided with a V-shaped channel (see Figs. 8 and 8a) which extends lengthwise of the anvil. The faces of channel 140 are at approximately right angles to the edges of the

fins

122 and 124. Thus when the top and bottom faces of the box parts are aligned with the edges of the

fins

122 and 124, being held therebetween in the shoulders 127 as shown by the outline of a box part 154 (dash line) in Fig. 6, the sides of the box parts will lie parallel to the faces of the V- shaped channel as shown in Fig. 7. It is also to be noted that the bottom surface 142 of hammer 14 is shaped toconform to the V-groove in the top of the anvil. The V-shaped channel is also provided with a lengthwise channel 144 at the apex thereof, which provides clearance for the pintle of the hinge. Each end wall 143 of the sleeve 80 is likewise provided with a V-shaped recess to match that of the anvil.

To use this embodiment, the shaft 60 is pulled out from underneath the hammer and a hinge 146 of the type described in said United States patents is placed on the V-groove as shown in Figs. 7, 8 and 8a. Previously to being placed there, the hinge has had attached thereto the spring clip 148, the effect of which is to hold the hinge in the position shown in Fig. 7 or in a position with the pintle slightly raised. The sleeve-guide 80 serves to center the hinge on the anvil, since the guide projects above the top edges of the anvil as explained above. Hinge 146 is, as described in said patent, provided with the upstanding burrs 150 thereon. The

box parts

152 and 154 are placed between the guide plates 122 and 124 (being held therebetween as shown in Fig. 6 by the pressure of the spring 114). This position is shown in Figs. 6 and 7, and it will be noticed that the box sides are superimposed on the hinge leaves. With the parts thus held positioned by their respective guides, the column 60 is now moved inwardly until the full line position of Fig. l is reached, wherein the hinge and anvil are beneath the hammer 14. Trip lever 52 is now depressed, and the rotation of pulley 42 by the motor 54 will cause the hammer to strike a blow against the anvil. This forces the burrs 150 into the box sides 156 and 158 and upsets the burrs 150 to anchor the hinge leaves to the box sides. An examination of Fig. 8a will reveal this upsetting operation, and also the fact that under the influence of the hammer, the sleeve guide 80 has been depressed to permit the hammer to seat firmly against the parts being fastened together. The groove 14a in the face of the hammer provides clearance for the pintle of the hinge when the hammer is fully down.

This being done, the clutch lever 38 is released, shaft 60 is pulled forward, and a second hinge is placed on the box, if desired, the box merely being turned end-for-end to space the hinge the proper distance from the box end. Or, if only one hinge is necessary, another hinge and pair of box parts is loaded for riveting.

Thus it is seen that the device provides ease of loading and unloading, ease of adjustment of the guides, and positive and accurate alignment of the parts to be fastened together,

is provided, and is pivoted at pin 162 which passes through The forthe lever and engages the sides of column 4.

ward end 164 has pivoted thereto the hammer 14 exactly as the hammer was suspended from lever 10. This embodiment works the same as the Figs. l-8 embodiment in regard to loading and unloading, guiding of the parts, placement of the hinge, the sleeve guide for the hinge, etc., the only difference being that the hammer blow is struck by foot pressure instead of by electric motor.

in view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained. 7

As many changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings, f shall be interpreted as illustrative and not in a limiting.
