.MACRIINE FOR MAKING WIRE-BOUND BOXES.

Patented March 2, 1909.

i Application filed November 9, 1907. fierial No. 101,522.

To all whom it may concern:

Be it known that we, Brennan G. INwoon and .Onnsrnn C. CHAPMAN, citizens of the United States, residing at South Bend, in the countyof St. Joseph and State of Indiana, have invented certain new and useful Iniprovements in Machines for Making Wire Bound Boxes, of which the following is a specification. j

Our inventionrelates to improvements in machines for uniting bodies of assembled members or blanks, or the like, preferably with staples for the purpose of fastening them together, and more especially for stitching or sta ling to each other in proper relation thes eets, cleats and bindin wires to produce blanks from which wire-bound rcceptacles, boxes, or other packages are to be constructed.

The wire-bound boxes referred to are usually rectangular in shape and having solid ends, the four sides being sheets or strips of thin lumber, or veneer, reinforced with inside cleats, step-mitered togetherat their ends, and with binding-wires extending around the said four sides. i

The principal object of the invention is to provide a machine. of novel and improved construction for makin more especially, the reinforced veneer ,blan 's to form the four sides of boxes as above described, which machine shall be of particularly simple-and durableconstruction, easy td 0 crate, and capable of manufacturing the .inished blanks with comparatively great rapidity and certainty'. 5

In the operation of our improved machine, in its preferred form, the cleats and sheet, .or sheet sections necessary for a complete blank for the four sides of the boil: when folded, are assembled,.one series at a time, in. proper relation upon guides which pass beneath the staple forming and drivin devices. The cleats and sheets are held in the proper spaced relation between the sections by spacin blocks, which, with the assembled cleats an sheetare caused to slide in the guides beneath the staple drivers, and as each section is stapled the spacing blocks are conducted to a point beneaththe front of the machine within easy reach a of the operator, whereupon they are a ain positioned upon the guides the spacer locks to be used over and over, and requiring the use of but two spacing blocks to a machine. Means are also provided on the carrier for feeding binding or strengthening wires beneath the staples, to be straddled thereby as they are driven through the. sheet into the cleats, and for thrusting such wires ahead in a etc by step motion alternating with the'operation of the stitching or stapling devices. This is one of the novel features of our invention, as the binding wire, during the operation of stitching or stapling, also serves as a means for feeding each section through the machine after the first staple is driven, as well as the finished sections previously operated upon; thus providing air exceedingly simple and effective automatic feed. In other] words the binding wires which form a permanent part of the box sections temporarily serve as a means, in connection with mechanism for positively feeding such wires, for feeding the assembled sections through the machine to be operated upon by the stapling devices.

In the accompanyin drawings, Figure 1 is a front elevation of the machine. Fig. 2 is a vertical cross section taken on a line X X of Fig. 1. Fig. 3 is an end elevation of the machine. Fig. 4 is a perspective view showing the four sections of a complete box blank before being folded. Fig. 5 IS a perspective view of the finished box. View of one of the spacing blocks used to hold the cleats and sheets in proper spaced relation While passing through the machine. Fig. 7 is an end view of the same. Fig. 8 1s a fragmentary plan view of one end of the box blank material, together with portions of the guide, the spacin block, and the binding wire in assembled relation. Fig. 9 is a sine view of the parts shown in Fig. 8. Fig. 10 is a erspective view of a ortion of the guide s owing a spacing b ock slidably mounted thereon.

As illustrated, the machine comprises suit able end standards, 1, adapted to support the operative parts of the machine, and are connected by suitable brace rods 2 and 3.

These standards are provided at their upper ends with slots 4 serving as guides for a s ing cross-head 5, carrying parts of a plurality of staple formers and drivers 6., These staple formers and 'drivers are relatively adjustable for different widths .of. box

Fig. 6 is a perspective blanks, so that each may be pro orly positioned to drive wires through the binding wires-in s astride tie binding mediate the end wires set into the cleats. The.

.low the sliding cross head and connected to'the standards 1 and upon which the re- 'inaining part of the staple forming and drivirom;

' one of the standards 1 an has its free end driven ,so long as ing devir es are adjustably mounted, and cooperate with the aforementionedlstapling forming and driving parts, to form the staple and drive the same into the assembled blank materialas the latter is fed through the machine. These staple drivers and formers may be of suitable construction, as they in themselves form no part of the present invention, and a detailed description. of the mechanism for forming and driving the staples not iven, it being suflicient to say that the wires from which the staples are formed are fed or supplied from reels, or ready made staples may be fed from a hopper, as may be preferred.

Mounted upon one end of the driving shaft 8 which is journaled in suitable bearings Qflis a power pulley 10. This (pulley is loosely mounted upon the shaft an is provide'd. with any suitable positive clutch mechanism 11, which is operable to couple the pulley to the shaft and to release it there- A foot-lever 12 is ivoted at 13 to connected to the free end of a tripping bar i l by a linlrlS. The bar 1% is arrangedv to hold the key (not shown) with which the clutch mechanism is closed and disconnected, helical spring 16 suspnded from a bracket 1'? and connected to said bar near its free endserving to normally hold thetripping bar elevated. The power shaft is thus only ressure is applied to the loot lever .12, whic action releases the tripping lever and allows the clutch mechanism to. close. Any suitable clutch mechanism may be used, and the particular manner or controlling the same is described only as a preferable form and operatesto retain the machine in. operation only so long as the operator retains his foot upon the foot lever, tl'iereby giving -him,perf ect control at all tines over the st ling operations.

Mounted upon the drive shaft-8 are eccentries 18 which are connected to sliding blocks 19 by pitmen 1 20. These sliding blocks move in the Islets-or ways i in the standards 1 and are partially a continuation or the upper sliding cross-head 5, so that the operation of the eccentrics imparts an up and down movement to said cross-head and the staple forming and driving devices mounted thereon. v

Secured to the standards on the front or feed side of the machine is a fixed shaft 21 upon which relatively adj ustable brackets-22 are mounted, and carrying upper and lower gears 23 and 2% adapted to mesh with each erases other. Formed integral with these gears are fi'eed' wheels, the lower oneof'which is formed with a peripheral groove 25 and the upper one with a peripheral rib 26 which is knurled on its face and extends into said groove and grips the binding wire 0, the object of which 18 to provide a positive feed for such wires, and feeding the same uniformly and accu rately in a step by stop motion through the guide tubes 27 to a pointboneath the staple drivers coincident with the drive of the staples. The smaller gears'24 may be mounted upon eccentric shafts 29 and herd in yieldable engagement with the larger or drive gear 23, bj contracting springs 30 fixed at their 11 per ends to the sides of the brackets 22, and t eir lower ends connectedwith the free ends of inwardly extending rods 31 carried by said eccentric shafts. This provides a yielding support and permits wire to be fed of varying gage without necessitating readjustment of any of the parts of the feed mechanism.

"he iced is controlled by a shaft 28 journaled in the standards 1, which projects through the gears 23 and is provided with a longitudinal slot (not shown) which is engaged. by keys carried by said gears so as to impart an intermittent rotary motion thereto and at the same time allow freedom of relative adjustment of the brackets 22 upon which the gears are mounted. The shaft 28 projects beyond the end of machine as at 32 upon the end of which a well known form of ratchet and pawl mechanism 33 is mounted.

The pawl is actuated intermittently by a con- 100 necting rod 34 pivoted at its upper end to the pawl and at it lower end to t e adjacent eccentric 18. T e pivotal point of this connecting rod is eccentric to the main drive shaft and designed tdgive fihefshaft 28 a partial turn 105' during the-u stroke of the eccentric, thus feeding thejbmding wire during the interval in which the stapling devices are on their upstroke. In other words, causing the feed of the binding wire to alternate with the driving 1 10 or" the staples. A like mechanism '36 as above describedior feeding the binding wires may be employed for-feeding the stapling wires to the staple forming and driving devices, the intermittent rotation of a shaft 37 115 which actuates the feed wheels, being accomplished by a lever 38 fulcrumed at39 to a bracket, and provided with an anti-friction wheel 40 which rests u on a cam 41 mounted upon the main drives aft. said lever is connected with a pawl 42 mounted upon the shaft 37 adjoining a ratchet wheel 43 by a connecting rod 44; The cam 41 thus imparts an up and down motion to the lever 38 and through its connections to 125 the shaft 37 actuates the stapling wire feeding mechanism 36. 1 I

In the assembling of the'parts which comprise the box sections, it is necessary to hold these parts in proper relation to each other 130 The free end of i 7 ends of the guides erases during the feeding of the same through the machine, and for that pur osc we employ two oppositely disposed guii e bars, 45. The inner end of these guides are provided with an enlargement 46 to serve an anvil, being channeled, to fit over a fixed beam 47, to which they may be locked against displacement by set screws 48, the outer ends of the guides {45 projectirn beyond t.-.c machine and supported interme late their ends by a cross bar 49. The anvil part of these guides are positioneddireotly below the point at which the staples are driven. The binding wires interinediate the end wires are straddled by the staples which are driven throughthe sheet and upset or clenched by the staple ends coming in contact with an anvil 50- adjustablynnounted upon the supporting beam 47, as no cleats are used at the center of the sheets. The guides 45 are slidable upon their supports 4-? and may be relatively ad justed fordid'erent widths of box blanks. The guides are provided with spaced ribs 51 and 52 extending upwardly from their base, forming a channel into which the cleats are placed and held-against lateral displacement. The base of each guide extends beyond the rib 52 thereof and serves as a seat upon which a spacer block for spacing the cleats endwise may rest. The spacing blocks are each formed in two portions 53-54- separated by a guide way, the portion. 54 bearing in the channel between the ribs 51 and 2- and the portion 53 bearing upon the base of the guide at the opposite side of the rib 552, with the separating guide wav bearing over the rib The portion 53 longer-than the portlon 54 and thus provides a relatively ong bearing surface upon the base and thus materially increases the steadiness of the movement. The portion 54 is also formed with reversely inclined faces 55 against which the ends of the cleats A abut. The portions 53 are also euchprovided with an upright pin 56 which serves to space the ends of the veneer sheets which form the b0 sides in rope-r relation to each other, so that they will no t bind when folded. The pins being located in the portions of the blocks 0 not interfere with the binding-wires or the action of the stapling-ma chanism. Located beneath the guides -15 and suitably supported, is an inclined chute 57, its upper end extending slightly beyond the inner end of the guides, to receive the spacing blocks as they fall from the guides and conduct them by gravity to a point convenient to the operator. A platform or table 58 may also be employed to receive the finished box blanks, an open space between the inner an the table being prope s-in blocks to drop vided to permit l into the aforemen ionedchute.

The operation of the machincis substantially follows:

The operator may corn-.3

sheets of veneer are then disposed u on the cleats with their adjacent edges a utting f against the upwardly extending spacing pins 561 on the spacing blocks. l sheets for the first two blank sections being- {now assembled in 1 proper relation to other, the operator manuallyiorward end portion of the same under the stapling devices in the first staples. be advanced so as to rest yond the end of the sheet and coincident with the staples to be driven. The operator "now trips the clutch 11 by de 'essing the foot lever 12, thus motion and causing the staples to be driven astride the bindingwircs through the veneer sheets into the cleats, and

the sheets intermediate the cleats and upon and extend beclenching them upon the anvil member 50.

one operation of the stapling devices 1 the binding wires are firmly attached to the assembled material 1 After root and cleats, and the of that section of the blank is thereafter auto-' matically fed through the machine by the '90 positive feed of the binding Wires which are thrust along by the feed-wheels in a stop bv i stop motion alternating in action with the stapling devices. When the last staples are driven into the first blanlesection the assenlbled material for the second section is pushed ahead by the o )erator, against the intervening spaccrbloclrs, to receive its first staples, after which it also is fed along step-by-step by the intermittently-opcrating wire-thrusting food-wheels. The third and fourth blank-sections are assembled and fed along in the same way, the machine being stopped after the last staples have been dr ven in the blank. a l it will thus be noted that an exceedingly I simple, cll'ectivc and novel automatic feeding device is provided, in which the binding wire which forms a permanent part oi" the box blank, and which is severed as the four sections of the blank are completed, momenl tarily serves as a means in connection with l the wire feeding mechanism to feed the as lscniblod box blank through the machine.
