VA-RIABLE RATCHET DRIVE FEED MECHANISM.

Application led September 30, 1919. Serial No. 327,583.

To ad whomit may concern l Be it known that I, JoHN SHELLENBERGER, a citizen of the United States of America, and resident'of Rome, Floyd County, State of Georgia, have invented certain nen7 and useful Improvements in Variable Ratchet Drive Feed Mechanisms and the like, of which the followinof is a specification.

This invention relates to certain improvements in actuating.;` devices forstep by step feed mechanisms and the like; and the objects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanation of the accompanying drawings illustrating what I now believe to be the preferred mechanical expression or embodiment of my invention from among other forms, constructions and arrangements within the spirit and scope thereof.

The wire bound box blanks of commerce are usually produced inelongated dat form of a length to bend along intermediate transverse lines so that a single blank will form two or more, usually all four, side walls of a box or container, with the binding wires continuous throughout the length of the blank and across the joints or spaces at said transverse lines between thesections of the blank.' These blanks 'usuallyconsist of thin pieces or boards of lumber or veneer, cleats or battens, binding wires, and staples straddling the wires and securing the wires, lumber and cleats or battens together.

The staples are arranged in rows along the binding,r Wires but the staples of a row are not uniformly spaced because of the joints or spaces between the various sections of the complete blank where staples cannot be located. These Wire bound blanks are usually produced by more or less automatic machinery wherein periodically movable or step by step feeding' mecha- .nism carries the properly assembled parts .of each blank forwardly to periodically movable stapling` devices, saiddevices applying1 the staples While Vthe feeding mechanism is at rest, the spacing of the staples longitudinally of the blank being determined by .thelength ofthe feeding or forward strokes .of the feeding mechanism. In these machines, the feeding mechanism is actuated by a ratchet` Wheel and pawl timed to move in certain relation with respect to the movements of the stapling devices. The

circumference of the ratchet wheel is usually of such length `that a complete wire bound blank will be stapled, will pass through the stapling devices, on eaclrcomplete revolution of said Wheel. In such machines, the throw of the ratchet is usually uniform or the same at every stroke, and hence the spacing of the staples is determined by the arrangement of the teeth of the ratchet Wheel. A ratchetI wheel can be of the proper diameter and have its teeth so arranged as to locate the staples as desired along a blank of a certain known length with a certain known arrangement of joints or spaces between the sections of the blank. In other Words, this 1atclietwlieel will constitute a pattern for a run of similar blanks uniform in size. Diiiiculties arise, however` when it is desired to produce blanks of a diiferent size or arrangement on the one machine. It then becomes necessary to provide a separate-ratchet wheel for each blank size or arrangement. A. blank of a different length requires a ratchet wheel of a different diameter with a different tooth pattern or arrangement, and a blank of the same length but with a different spacing of the joints or spaces between the sections will require a ratchet Wheel with a correspondingly peculiar tooth pattern or arrangement.

This saine difficulty is true of ratchet- Wheel-actuated step by step feed mechanisms in machines used for other purposes and work than stapling, whenrit becomes desirable to vary the spacing or the lengths ofthe steps making up a' complete operation.

It is the object of my invention to provide ratchet actuating1 means for step by step feed mechanisms wherein the ratchet teeth or elements movable in an endless path can be increased or decreased in number and wherein the spacing or arrangement of such teeth can be varied. with the end in view of overcoming' the hereinbefore mentioned difficulties.

With these and other objects in view, my invention consists in certain novel features inV construction and in combinations and arrangements as more fullyT and particularly set forth. and specified hereinafter.

Referring to the accompanying draw- -indes- Figa` 1, illustrates one among other applications4 of `my invention; said figure parlil) vstep by step.

the full Width of teleth in a broadl or generic sense to iuclude any suitable projections or shoulders or other means with which the ratchet chain is provided and with which the pawl or its equivalent cooperates to advance the chain As an'example I show the chain illustrated, provided With'outwardly (radially) extending projections or lugs c havingl transverse concavities or rounded depressions a in their rear end edues and also preferably intheir front end edges. Each concavity preferably extends across the lug and is located intermediate the length of the lug end. In this example, these lugs are rigid with and project outwardly from certain links a of the 'chain and are offset from the central portions of the links, i, e, each lug is located relatively close to one end of its link and relatively remote from the other end of its link and both ends of the lug are formed to operatively receive the pawl.

The chain, in the example shown, is made up of series of links4 a, as, c, detachably and pivotally connected in any suitable or Well known manner as hy pivots a5. The links are detachably connected so that links can be yremoved or added to increase and diminish the length (circumference) of the chain, to reverse any one or more of the links a, or to arrange the links a accordinp,` to any desired spacing either uniform or irregular.A The idlersprocket wheel 14 can be adjusted to correspond to the length of the chain and maintainl the chain stretched as may be required, by the addition or removal of chain links.

The pawl b'can be of any suitable construction and formation and moved back and forth on its operative and return strokes by 'any suitable means and in any desirable manner although the operation ofthe pawl is, in this instance, timed with the operation of the stapling devices so that the stapling devices will 'perform their stapling operations on the blanks while the pawl is on 4its return strokes with the feed mechanism at rest and hence so that the stapling devices will be at rest so far as the blanks are concerned while the feed mechanism is performing its feedingr strokes.

In the example illustrated by certain figures of the drawing, I show the paw] carried by and pivoted toa gear or toothed sector 25 loosely mounted on shaft 9 and arranged beside sprocket 12 with the pawl above the chain and its free end restingI loosely thereon. This pawl carrier is swung;

Aor osc-illated by 'lever 26 fulcrumed to a frame standard 54 and having a toothed sector meshing with the teeth of the pawl carrie!1 25. The depending long' arm of the lever is pivotally connected with the drive shaft 4 through the medium of link 27 and eccentric or crank connection 28. This y completed crank connection is preferably adjustable and the connection between link 27 and lever 2G is also preferably adjustable for obvious purposes, such as varying the throw or stroke of the pawl.

It' so desired, the pairl Z) can he mounted on lever or carrier 25 to the lower end of which the link 2T to the crank of shaft 4 can he -pivotally joined. The pawl .7; can be carried by a slide instead of a. swinging;r or piifoted carrier. For instance, the pawl I) can be pivot-ally slide 25b so that the free end of the paivl operatively engages the ratchet chain. This slide is confined to reciprocate in guidcwny 28a carried by bracket 17. The slide is reciprocated in the desired sequence with re spect to the operations of the stapling devices by the crank 28 of shaft 4 through the medium of lever 26 and links 26 and 26". j

I do not wish to limit my invention to any particular pawl carrier and means for operating` the same.

The pawl b is so arranged with respect to the ratchet chain and its teeth, that on its return stroke the pawl will slide loosely along' the ratchet chain and over a ratchet tooth and drop behind said tooth, and then on its operative stroke, the free end of the pawl will engage the rounded depression or conravity a of said tooth and rotate or more the ratchet chain forwardly the required distance to advance the feed and blanks carried thereby a step or feeding movement.

In the specic embodiment illustrated, the concavities a are of advantage in holding the panl to the tooth and prcventin the pawl from slipping from the tooth and in reducing wear to the minimum. The pawl moves a fixed and predetermined distance on each operative stroke. and hence the length of the advance of thc feed and blanks at each feeding stroke is controlled by the arrangement and spacing of the ratchet teeth. The spacing` and location of the staples longitudinally of the completed blank is determined by the location and spacing of the ratchet teeth along,r thc endless ratchet connection or wheel, and hence said connection or wheel forms a patrn for the stapling arrangement on the blanks.

In practice,A the length of the ratchet chain or endless connection, the circumference thereof, is preferably equal to the lengthof the completed blank plus the distance or spacing between the rear end of a blank and the front end of the succeeding blank. The ratchet teeth on the ratchet chain indicate or represent the tra nsveise portions of the blank that Will be successively presented to the stapling devices to receive transverse rows of staples, and the location of each ratchet tooth on the ratchet joined to a reciprocatingA e; This 'spacing vo verse rows oi' staples on the v each `sheet countered in Y ating devices and attached so.
