To /ZZ whom it may concern:

Be it known that we, PEROIVAL D. MOODY and ARTHUR E. MOODY, citizens of the United.

States, residing at New York, .in the county of New York and State of New York, have invented certain new and useful Improvements in Butter-Tray Machines, of which the followingis a specification.

This invention relates to and has for an Ob? ject to provide an improved machine for manufacturin butter-trays,particularly such as are made From thin wood or veneer and are bound with sheet metal.

In the drawings accompanying and forming a art of this specification, Figure 1 is an end e evation of a form of machine embodying our present improvements.l Fi 2 is a plan view thereof. Fig. 3 is a side e evation ofthe same partly broken away. Fig. 4 is a perspective view of a form of product ofthe Fig. 5 is an enlarged side. view, partly shown 1n central section, of the forming-head. Fig. 6 is an enlarged view of ashear and forming-head for the metallic ends or binders. Fig. 7 is an enlarged view, partly shown in section,'of a device .for assisting in the formation of the metallic binders and for applying the same tothe tra s. Fig. 8 is an en view, somewhat enlarged of the cuttinghead for cutting and creasing the ends of the blanks for the trays, and Fig. 9 is a plan view of a portion of stock, showing the cutting and creasing of the blan The various parts of the machine ma be mounted in a compact framework, w 'ch ma have a base portion (designated in a g'enera way by 20) adapted to stand upon the floor or other-convenient base. i Bearings 21 will be provided in the end of the framework to support the driving-shaft 22, which is l driven froma pulley 23 by a belt` from some suitable source, of power. This shaft carries some of the cams and some of the gearing. A pair of shafts 24 25 are supported upon the respective sides of the machine, the shaft 24 by brackets 26 afording it suitable bearings, such shaft 24 havin a miter-wheel 27 in mesh with a miter-whee 28, upon the driving-shaft. The shaft 25 is similarly supported by bearing-brackets 29 and has a mlter-wheel 30 in mesh with a miter-wheel 31 upon the driving-shaft.

A form Iof the product of the machine is represented in Fig. 4 and comprises in the (Not shown.

present illustration the well-known fOIIIl 0f utter-tray'40, comprising a bottom 41, sides 42, and ends which are comprised of an inside A, end portion 43 and overlapping portions 44,v

lines -46 47 illustrate the line of severance for each blank, which lines will make the edges 48 of the sides of the completed tray. In

such Figli) the portions of the blank whichV enter into the tray are iven the same reference characters as they ear in Fig. 4 for the pur ose of comparison. At the position 49. a

smal triangular iece of stock lis removed, this being to pro uce the illustrated form of product, the only portion of the stock which 1s removed. Each blank is cut, as at 50 51, 'tO permit the lapping of the end portions 44 44 over the portlon 43. The blank is also creased at 52 to permit the ready folding of the ends in the machine.

The blank 15, which, according to the present prevailing thin Wood, is fed into the machine mFig'. 2 from thev` left-hand end and passes under a cuttin -di (designated in a general way by practice is made of veneer or 60,) a eed being accomplished by the follow'- i in instrumentalities: There is shown a feedtale 61, having rollers 62 running upon a track 63 ofthemachine-frame, and which carriage is normally drawn toward thel end of the machine,at which-the stock enters by means of a retractile sprin 64. The -stoc is fed over this table, and a s oe 65 rests upon the table or, rather, upon the stock which is upon, the table during the feed movement, but is moved away fromit durlng the backward movement or movements to gain a fresh hold upon the stock.y The shoe has a body portion 66, provided wlth ways 67, which are carried by ways 68 upon arms 69, pivoted to stub-shafts 70, earned bybearings 71, fast upon the machlne-frame, and which arms are connected together at their free ends by means of a pivot..72, carrying a roll 73, which may be engaged by a cam-bke arm 74, fast upon a rock-shaft 75, adapted to be rocked by an arm 12, fast upon such shaft, and engaged by a cam 76, fast upon the shaft 95, the ro 74 in the present instance by means of springs 77.

l 73 being held against Yits actuator each side of the machine for forming therepective ends of the blank. Each cutter-head has a slide portion 90, running in ways 91 I5 upon the machine-frame, and is retracted to its inoperative position and driven to its work in the present instance by means of an' 93 upon a eccentric 92 and eccentric-stra pitman93., connected to the sh e portion 9.0,

2o which eccentricsv are mounted'upon a shaft- 95, mounted in bearings u on the riser or.

l tions 96 of the maolnne ame, and W 'ch shaft has a beveled pinion 97 in mesh with a c bevel-pinion 98 upon the shaft 99, supported by bearing-brackets 100, and which shaft 99 has a miter-Wheel 101 in mesh with amiterwheel 102 upon the shaft 25.`

\The tra -forrning mstrumentalities are lo cated in such a position that theywill act 3o during vthe incising of the end portions of the blank, but in such aposition that there will be a blank width between the two devices as they are in operation. This of course is merely a structural feature, but is mentioned g for the sake of clearness of description.

l'tray forming or folding head is designated in \a` general wa by 125 and is provided with 'a v matrix-like c amber126, whlch will zconform substantially to the outside of the lcompleted- 49 tray and which cooperates with a forming member127, which will conform substaniv tially to, the inside of the tra The memt-l ber 125 is carried by a shan portion' 128, which is in the nature of a slide running in` ways 129 upon the machine-frame and whichis adapted to be retracted in' the presentinstance by suitable coiled springs 18. The frame or slide portion 128 carries a roll v13() for the engagement of a cam 131,y fast upon 5o' the shaft 132, which has fastv tofit a earvWheel 1133, in mesh with an idler 134, W ich in turn meshes with a gear-wheel 135, fast upon the shaft 95.

The portions of the molding or forming member which are to take the lapped. portions of the box in the present instance referred to as ends, carry members or fingers 140, pivoted at 141 to a removable block 142 and which are impelled toward the chamber 6o 126 by springs 143, which 1in ers are adapted to engage the portions 43 o the blank and fold them down slightly past the predetermined nished position. Then upon the former sinking upon the internal former or folder 127 the portions 44-will be lapped into posltion,

forming instrumentalities.,

The

owing tothe walls of the chamber 1.26,. and the portions 43 will, with the iingers 140, move outwardly to their properlpositions,

for that particular box will be severed means Aof a knife 144, carried byv such hea and which knife may be so adjusted that it willl severv the blank from -the stock before any portion of it has been engaged by the The stock may be' guided to the former'by guides 145, securedl toLi each side of the ma- 4 chine-frame, which Vides .may in ,some 1nstances extend b'acube ond the Working pointof the Iformer an may extend wel over the same to "position the blank at the inauguration ofthe forming operation. The guides may be bridged by a brace 146 to oa thes rin s77. l .i

'le t e b ank which has been folded and out' r forming members the parts will be bound together .with strips of sheet metal. The sheet metal will be applied to the lapped or folded end ofthe trays, bein bent over the edges and' clampedagainst t `e sides adjacent to such edges, thus making a metallic rim on the portion of the tray at which the "material from which it is made is lapped or folded, In the present illustration' the lap- ,pingis at the ends of the tray. For such each side, andthe feed members yfor such stock 1n the present illustration are shown as rduplicates one of the other, andthe descri tion of one will answer for the other. T e stock is fed betweenv a pair of feedrolls 151 1525', which'are journaled in blocks 153. 154,

.carried'by a frame 155, in which they may have verticalmovenent, the upper block be- 'ing guided by a pin 156 and pressed toward the vother by means of a s ring 157, and one of the-rolls may be provi ed with a ratchet 158,-en aged by a pawl 159, having a vortion 160 em racing the shaft 24 or 25, as t e case may be, and carrying an eccentric-strap 160, actuated by an eccentric 161, u on` such shaft, whereby u on the rotation o the shaft the stock 150 w11 be fed into the ,machina There is provided at each side of the machine a cutter-head 165, having a shank portion 166 in the nature of a slide 'supported 1n ways 167 and adapted to be drawn away and he d in its idle position by some suitable meansas, for instance, a coiled sprin 16S-and being provided with a shoe encl gaged by a cam 1.70 upon the s aft 132. Such cutter-head in the present instance comprises a shear 171, mating Witha shear 1712 u on the table 173, over which the stock 150 is ed. The head also comprises a forming member As the head 125 is moving down to- Ward the stock to engage the same the blank.
