TRAY-MAKING MACHINE.

Continuation of application Serial No. 71,931, filed January 13, 1916. This applicationfiled November 11,

1919. Serial No. 337,302.

T all whom it may concern Be it known that I, HENRY BRADY, a citizen of the United States, residing at Bloomiield, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Tray-Making Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in the manufacture of containers, and more particularly has reference to a machine adapted to form boxes out of a sheet of heavy paper such as card, and is a continnation of my prior patent application Ser. 1

Referring to the accompanying drawings, Figure 1 is a view of a machine in side elevationembodying'an application of my invention. Figure 2 is a plan view looking down upon the same. Figure 3 is an enlarged detail of part of the cutting Inechanism. Figure 4 is an enlarged detail of part of another cutting mechanism- Figure 5 a front elevation of part of a box forming mechanism. Figure 6 a cross sectional view on the line 6-6 of Figure 2. Figure 7 an enlarged detail, partly broken away, il-- lustrating part of the transmission mechanism Figure 8 an enlarged cross section on the line 8-8 of Figure 4. Figure 9 is an enlarged perspective view of part of the folding mechanism, and Figure 10 is an enlarged perspective viewv of part of the transmission mechanism.

10-10 are suitable legs or standards upon which the machine is mounted, and 11 the main frame or platform of the machine. 12 indicates the driving pulley which may be driven by a suitable belt such as 13, and 14 is the main drive shaft suitably mounted in the frame, as shown, and, provided at the opposite end with a pinion such as 15 which meshes with the gear 16 which in turn is mounted upon the shaft 17- Upon the same shaft at opposite ends is also mounted suitable cranks such as 18 -18 which in turn are connected to suitable levers such as 19- 19 which are provided with suitable racks such as 20 shown to better advantage in Figure 7, which in turn mesh with pinions such as 21 upon bolts or pins such as 22. Upon the said bolts or shafts such as 22 are also mounted ratchets such as 23 which are engaged by suitable pawls such as 24, thus being free to turn in one direction only. As the drive shaft 14 rotates, the gear 16 i is driven by the pinion 15 and in turn ro tates the cranks such as 18 which operate the racks such as 20 thereby rotating the pinions 21 which carries with it the disks carrying the'pawls such as 24, so' that in rotating leftwardly looking at Figure 10, the pawls 24 engage the ratchet wheels such as 23 which are to'the' right of the disk members 25 and which are connected to the gears such as 26, said gears 26 being connected to saiddiscs or plates 25 by suitable means suchas the plates 27 and beingin mesh with the pinion such as 28 upon the shaft 29 which carries the roller 30'overwhich the band 31 travels, which said band also travels over the roller '32 and beneath the rollers 33, as shown to better advantage in Figure 1.

The arms or cranks l8--18 upon the ends of the shaft 17 to which are connected the rods 1919, it will be observed, impart an intermittent and alternating rotary motion to the gears or pinions such as 2l which carry the disks 25 causing the pawls such as 24 to engage the ratchets 23 on alternate strokes thereby rotating the gears and pinions 27 intermittently andat the same time causing the shaft 17 to lift intermittently the die plunger 34 and die 35 for'embossing or marking the card or sheet, the shaft, 17 being mounted in the blocks 3636 which travel in the clearances 3737 vertically and the plunger 34 being guided in the frame as indicated at 3838.

The roll of card or heavy paper from 42 and 43, the same being driven by the pinion 44 in mesh with the gear 45 upon the shaft 46.

From the foregoing it will be seen that the paper is fed beneath'the die 35 intermittently where it is embossed or marked and from;

there under the rollers 33 to the cutting attachment shown to better advantage in Figure 3 in which the shaft 47 is provided with a beveled pinion such as 48 which meshes with a bevel pinion 49 upon the shaft 50 tatably secured in the base of the supports 58-58 to rise and fall, thereby drawing down the frame 59 against the action of the springs 60-60 which normally tend to keep the frame in its uppermost position. 61-61 are knives adapted to make triangular cuts in the sides of the advancing card or sheet,

said knives being secured to the front as shown, thus cutting the card or sheet in the necessar form for the foldin o eration to be hereinafter described.

Upon the said shaft 50 is also mounted a beveled pinion such as 62 which in turn meshes with the beveled pinion 63 upon the shaft 64, said shaft 64 being provided with cams such as 65-65 upon which are retained suitable rollers such as 66-66 mounted in the lower ends of the arms 67-67 supported by the bridge or yoke 68 which in turn is projected upwardly by suit- 70 is a suitable springs such as 69-69. able frame carrying pins such as 71 which 1 penetrate the slots 72 of the knife support so that as the cams 65-65 rotate, the yoke or frame 68 is pressed down periodically against the action of the springs 69-69, thus driving the knife 73 downwardly in contact,with'the other knife 74, and as the card or sheetfeeds between said knives the same is out along predetermined lines.

On said shaft 6 1 it will be observed on reference to Figure 2, that a suitable sprocket such as 75 is secured which carries a sprocket chain 76 which passes over the sprocket wheel 77 upon the shaft 78 which in turn carries the roller 79 and belt 80, suitably mounted as shown. The belt 80 it will be observed serves to rotate the rollers such as 81, thus causing the cut piece of card or sheet to feed forwardly into place beneath the forming apparatus shown to better advantage in Figures 5 and 9; x

Upon the said shaft 6 1 it will be seen is also mounted the sprocket wheel 82 carrying the sprocket chain 83 passing over the sprocket wheel 84, upon the shaft 85. The said shaft 85 it will be observed is provided with suitable cams such as 86-86 in the sides of which are provided suitable guides for the rollers 87-87 which are mounted in the rods 88-88 secured to the ends of the former 91 presses downwardly upon the same, partly forming the box into its final shape, the former 91 being projected in advance by the spring 91". On the four corners of the former 91, it will be observed on reference to Figures 1 and 9, particularly that a hinged member such as 93 is provided having a pivoted flap 94 provided with a finger 95 which engages the guide plate 96 upon the frame or table, as shown said guide having a pivoted member 97 resiliently secured by any suitable means such as spring 98 with the. result that as the former 91 descends, the finger 95 of the flap 94- engaging the guide 96 is forced outwardly and the flap or pivoted member inwardly thus turning inwardly the corner of the box until it is parallel with the end thereof when the finger 95 is stopped by the resilient member 97. The box is now formed with the four sides bent into position and the four corners turned over the ends thereof and is ready to be secured.

Upon the said shaft 85 it will be observed is also provided cams such as 99-99 upon which ride the rollers such as 100-100 mounted in the ends of the rods 101-101 which. in turn are pivotally secured to the yoke 102. On reference now to Figure 1 it will be observed that the yoke 102 engages the ends of the bell cranks 103-103 pivotally mounted in the standards 104-104 and pivotally secured to the stitchers 105-105 which are slidably mountedin the frame or support 106 as shown, so that as the yoke 102 risesand falls .upon..the cams 99-99, the stitchers 105-105 are brought into operation against the ends of the formed box in the usual and well known manner in which such stitching apparatus operates. Of course it will be understood that the die block or forming bracket. 92 may be secured upon a suitable standard or shaft such as 107 provided with a roller such as 108 which rides upon the cam 109 mounted upon the shaft 85, so that the forming block or die is raised slightly soas to securely hold the card or sheet such as 39 within the former 91. After the forming and stitching mechanism has operated, the plunger 110 upon the end of the rod 111 provided with roller 112 which rides upon the cam 113 of the shaft 85' is driven upwardly thereby turning the ends of the wire or other material with which the stitching is done and leaving the box completely formed and fastened ready to be discharged from the machine.

Of course it will be understood that various modifications may be made in. the construction and arrangement of parts without departing from the spiritof the invention as claimed. I 1
