FEEDING APPARATUS FOR W OOD STRIPS.

SPECIFICATION forming part of Letters Patent No. 730,920, dated June 16, 1903.

Application filed March 81, 1 902.

To all whom it 1mg concern:

Be it known that I, PETER J. JOECKEN, a citizen of the United States of America, residing at Oleveland,'in the county of Ouyahoga 5 and State of Ohio, have invented certain new and useful Improvements in Apparatus for Feeding Strips or Bars of lVood or other Material; and I hereby declare the following to be a full, clear, and exact description of the IQ invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in apparatus for feeding strips or bars of any i 5 material, and pertains more especially to ap paratus which is well adapted for feeding staves to an endless carrier or conveyor.

The object of this invention is to provide apparatus of the character indicated, which will feed intermittently, which is simple and durable in construction, and reliable in its operation.

IVith this object in view and to the end of realizing other advantageshereinafter ap- 2 5 pearing my invention consists in certain features of construction and combinations ofparts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure I is a top plan of apparatus embodying my invention. Fig. II is a left-hand side elevation relative to Fig. I, partlyjon'line II II, Fig. I. Fig. III is a vertical section on lines III III, Figs. I and II. Fig. IV is avertical section corresponding with Fig. III, except in the position of the movable parts.

The apparatus illustrated comprises two standards aand a,which are placedvertically and a'suitable distance apart laterally;

40 Each standard (9 is provided upon its inner side with two inwardly projecting parallel flanges a,which extend vertically of the standard and are arranged a suitable distance apart transversely of the standard. The standards a, with their flanges a, form a hopper which is uniform or approximately uniform in dimensionsfrom top and bottom, open at the top and bottom, and open also and preferably, but not necessarily, between opposite flanges a of the different standards a, respectively. The

standards a are far enough apart to accombetween the said standards:

Serial No. 100,749. (No model.)

modate the placing of the stavesor other strips or bars I) of wood or metal, which are to be fed by my improved apparatus, longitudinally The bars or strips 19' are piled between the standards a upon two shelves 0, which are movablewithin and laterally of the different standards, respectively, and the path of the strips or bars I) is downwardly to an endless conveyer or carrier comprising two endless chains (l, arranged a suitable distance apart laterally between and below the travel of the said shelves. The standards a are slotted laterally, as at a to accommodate the location and operation of 6 5 the shelves 0, which are actuated simultaneously from or toward each other, as will hereinafter appear. The shelves project in their extreme inner position, as shown in Figs. I and III, into the path of the bars or strips 1) and extend under opposite ends, respectively,

of the lowermost strip or bar I) of the pile of bars or strips '1) between the standards a and support the said pile. V The shelves 0 in their extreme outer position, shown in Fig. IV, are outside of the path of the members of the said-pile and obviously do not support the pile, which is then supported by detents e.

Above each shelf care a series or plurality of movable detents e, which are arranged such a distance above the said shelf as to accommodate only the thickness of one bar or strip 12 between the travel or sweep of the shelves 0 and the path orsweep of the said detents,

as shown in Fig. III. The detents 6 above each shelf 0 are arranged directly opposite the detents 6 above the other shelf 0 and are actuated simultaneously with, but in a direction opposite to, the actuation of the last-mentioned detents, as will hereinaftermore fully appear. The detents care in their extreme outer position arranged outside of the path of the strips or bars Z), as shown in Figs. I and III, and in their extreme inner position extend far enough intothe said path to cause 5 them to bite or' arrestively engage the adjacent end of the adjacent bar or strip b and support the pile of strips or bars I) remaining between the standards a overthe said engaged strip or bar which is then the lowermost mem- Ice 1 her of the said pile, as shown in Fig. IV. The standards a are slotted laterally, as at a to accommodate the location and operation of the detents e.

Each standard a is provided at its upper end and upon its outer side with two aprons f and h, arranged the former within the latter cam 70, with which a suitable applied shaft It,

which is driven by the adjacent chain d of the aforesaid endless carrier or conveyer, is provided. The said inner apron fcarries the detents e, which are movable within the said standard, and has an arm f, which operatively engages a cam with which the said shaft 7c is provided. There are therefore two shafts it and k, arranged in line endwise and a suitable distan ce apart and adjacent to the different standards a, respectively, and two corresponding sprocket-wheels k and 70 are operatively mounted on the different shafts 7c and 76, respectively, and o'peratively engage the different chains (1 and (1, respectively. The chains d lead from the wheels k to and operatively engage sprocket-wheels m, which are operatively and slidably mounted on a suitably-applied shaft m, which is operatively provided with a driving-pulley m to which power is applied in any approved manner. Operative engagement between the wheels m and th'eshaft m is shown established by the well-known means of groove and feather, as at m", (see Fig. 1,) so that the said wheels m can be adjusted apart to correspond with the distance between the wheels 70*.

A bed-plate 7' extends under both standards aand each standard a has a base a, which rests upon the said plate. The base a is secured to the'bed-plate '1' by bolts 25 and nuts 71, which bolts are arranged with their heads adapted to bear against the under side of the bed-plate and with their shanks extended upwardly through corresponding holes 7'', formed in the said plate, and upwardly through slots a formed in the aforesaid base and the said nuts are mounted on the shanks of the bolts at the upper side of the said base and the aforesaid slots are arranged parallel with the strips or bars I) piled between the standards a, and consequently the said standards upon loosening the nuts n are rendered free to be adjusted apart to accommodate the length of the bars or strips 1) which are to be fed to the endless conveyer or carrier from between the said standards, which are secured in the desired adjustment upon tightening the said nuts.

The cam-shaft is, instrumental in the operation of shelf 0 and detentsewithin a standard a, is supported in any approved manner from the base of the said standard, and consequen tly both shafts 7 are shifted as required with the standards during the adjustment of the standards toward or from each other. The flanges a of the standards are arranged far enough above the endless carrier or conveyer to avoid interference with the said conveyer or carrier in adjusting the standards or upon the bed-plate.

By the construction hereinbefore described it will be observed that the chains (1 are driven in unison during the operation of the shaft m, andthrough the medium of the sprocketwheels 10 rotate the shafts k in unison, and the arrangement of the parts and the trend of the working surfaces of the cams k and k are such that the two shelves 0 and the detents e are simultaneously actuated; that the said shelves are actuated alternately into and out of the path of the bars or strips 1) introduced between the standards; that the detents eare actuated alternately into and out of the said path; that the shelves at the commencement of the operation of the apparatus are in their inner or operative position and support the bars or strips b dropped or introduced between the standards a, as shown in Figs. I and III; that the detents e at the beginning of the operation of the apparatus are in their outer and inoperative position out of the path of the said strips or bars, as

shown in Figs. I and III; that the detents e move inwardly into their inner and operative position during the movement of the shelves 0 into their outer and inoperative position; that the lowermost strip or bar 1) drops onto the chains d of ,the endless carrier or conveyer upon the actuation of the said shelves into their outer and inoperative position; that the next lowermost bar or strip 1) is arrestively engaged at the ends by the detents 6 during the actuation of the said detents into their inner and operative position, and consequently only one bar, or strip 1) drops at a time from above the shelves 0 onto the aforesaid carrier or conveyer during the operation of the apparatus.

The detents e havetheir ends preferably somewhat sharp or tooth-shaped to render them capable of biting, and thereby more positively engaging the next lowermost bar or strip b during their operation.

To accommodate imperfections in the ends of the strips or bars I) placed between the standards, or slight Variations in the length -of the said bars or strips, and to avoid the necessity of exercising nice care in placing the said strips or bars between the standards, and to avoid splitting or mutilation of the ends of the said bars or strips, the detents e are capable of yielding endwise against the action of suitably-applied spring 3 or equivalent means. (See Figs. III and IV.) Preferably each detent e extends through and has bearing in the lower or free end of the inner apron f, which carries the said detent, and a spiral spring sis coiled upon the said detent and confined between a shoulder f formed in the said apron, and a shoulder 6 formed upon the said detent between the aforesaid shoulder f and the inner or forward end of the detent, and a stop-forming pin 00 extends through the outer end of the said detent at the outer side of the said apron f and in the outer and inoperative position of the said detent engages the said side of the said apron, as shown in Fig. III, and thereby limits the inward movement of the detent independently of the apron.
