ELMER S. FOSTER, OF NEW MIDDLETOWN, INDIANA.

HOOP-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 553,282, dated January 21, 1896.

Application filed May 8,1895. Serial No. 548,588. (No model.)

T0 all whom, it may concern:

Be it known that I, ELMER S. FOSTER, a citizen of the United States, residing at New Middletown, in the county of Harrison and State of Indiana, have invented a new and useful Hoop-Making Machine, of which the following is a specification.

This invention relates to an improvement in hoop-making machines, being designed especially for the manufacture of hoops from riven wood for use in connection with tobacco-hogsheads.

The object of the present invention is to provide a reliable and efficient machine for operating upon and dressing strips of riven wood in such manner as to shape said strips into proper form, for adapting them to be utilized as hoops designed particularly to be used for bindinggtogether the staves of tobacco-hogsheads and other articles of a similar nature.

The invention consists in certain novel features and details of construction and arrangement of parts, as hereinafter fully described, illustrated in the drawings, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is' section taken through the machine in line with the several feed-rolls, planer-blocks,

die. Fig. 3 is a plan view of the complete` machine, with parts broken away to betterl illustrate the general construction and arrangement of the parts. Fig. 4E is a detail view of the sliding frame in which the selfacting spring-actuated roll is mounted, showing also the spring which actuates said roll. Fig. 5 is a detail view of the pivoted guiding frame and lever, showing also the verticallyelongated guide through which said lever operates.

Similar numerals of reference designate corresponding parts in the several figures of the drawings.

Referring to the drawings, l designates the main frame of the improved hoop-making machine, said frame being formed preferably of hard wood and composed of a series of upright posts or standards connected by suitable longitudinal and transverse-bars or timbers firmly held together by meansv of tiebolts, as shown. The upper portion of the frame thus constructed is provided with three longitudinallyextending frame timbers or bars extending the entire length of the machine and serving as an elevated bed or table, upon which is mounted the mechanism which will now be described. The central longitudinal bar or timber 2 is arranged in such relation to the, side bars 3 that a suiiicient space is left upon one side for the various feedrolls, planer-blocks, dto., while the space on the opposite side of said central bar or timber is adapted to be occupied by the several gearwheels, pinions, and pulleys through which and suitable belting motion is communicated to the various operative parts of the machine.

The main driving-shaft of the machine (indicated at 4) is mounted in bearings at the rear end of the frame and is provided at one end with a band-pulley 5, through which it receives motion from any suitable motor by means of an interposed belt. The main driving-shaft has upon its opposite end a large band-pulley G, from which a belt extends around the pulleys on the shafts of the planer blocks. The main driving-shaft is provided with another small pulley 7, from which a belt extends forward and drives the several smooth and iluted feed-rolls.

The pair of feed-rolls through which the material is fed from Athe machine is located near the rear end of the machine and provided with smooth cylindrical surfaces, as shown. These feed-rolls (designated by the numeral 3,) are mounted upon transverse shafts and provided at their adjacent ends with spur-gears 9, which are always in mesh and thereby drive said rolls in opposite directions, adapting them to engage both the upper and lower surface of the material fed thereto and to pass the same onward out of the machine. The lower one of these feedrolls 8 is keyed to its shaft and said shaft is extended upon one side of the frame in which it is journaled where it is provided with a band-pulley l0, through which it receives motion. In order to support the feed-rolls S at the proper elevation, so as to bring them into horizontal line with the other feed-rolls of the machine, an oppositely-disposed pair of bearing-blocks 1l is mounted upon the

longitudinal timbers

2 and 3, extending upwardly therefrom and extending sufficiently IOO the shafts of said feed-rolls 8.

The upwardly-extending bearing-blocks 11 are further provided with bearings for the reception of a transverse shaft 12, upon which is pivotally mounted a forked or bifurcated frame 13, carrying at its front end a guidingroll 14 revolubly mounted between the oppositely-disposed arms-of said forked frame Aand located immediately above or in vertical line with the lower and rear planer-block. Extending rearwardly from said pivoted guideroller frame is an operating-lever 15., arranged within convenient reach of the machine attendant. In order to support said operating-lever and guide the movements thereof, a vertically elongated or slotted frame 16 is provided, said frame having laterally-projecting arms or extensions 17 by means of which it is attached to the upper edges of the bearing-blocks 11.

18 designates the rear and lower planerbloek, which is keyed to a transverse shaft mounted in bearings upon the longitudinal frame-

bars

2 and 3 and provided at one end outside of the frame and in line with the large pulley G with a band-pulley 18., by means of which the planer -block is driven. The planer-block 13 is provided upon opposite sides with the usual planing-knives, as indicated at 20, said knives being slotted and adjustable by means of set-screws in the usual manner. A similar planer-'block 21 is located in front of the block 13 andin a higherplane, being also keyed to a transverse shaft, upon one end of which is mounted a pulley 22 by which said planer-block is driven. The planer-block 21 is also provided with slotted and adjustable planing-

knives

2,3. A suitable guiding-belt 24 extends around the large driving-'pulley 6, thence over the pulley 19 on the shaft of the lower planer-block, after which it passes over and around the pulley 22 on the shaft of the upper planer-block, 2l. M otion is thus imparted to the upper and lower planer-blocks and said motion is necessarily rapid owing to the relative sizes of the pulleys described.

Located intermediate the planer-blocks just described is a pair of feed-rolls, the lower one of which is provided with longitudinal corrugations and is mounted upon a transverse shaft journaled in the machine-frame. This fiuted or corrugated roll 25 is located in about the same horizontal plane with the lower feedroll, 8, above described. Located immediately above said feed-roll 25 is a smooth feed-roll 26 which ispivotally mounted in the free ends of an oppositely-disposed pair of spring-arms 27, secured to the

longitudinal bars

2 and 3 upon the u pper faces thereof. The tension of said spring-arms is exerted to force said smooth -feed-roll 26 toward the fluted or corrugated roll and the distance between the two rolls may be regulated by means of set-screws 28,

arranged with their upper ends beneath said spring-mmsl and engaging threaded sockets in the machine-frame. The iiuted and smooth feed-rolls just described constitute the main feed-rolls of the machine, being adapted to grasp the strips of riven wood after they have been acted upon by the upper planer-block and to force the same onward over the lower planer-block.

29 and 30 represent a pair of feed-rolls mounted in bearings near the front end of the machine. The lower one of these feedrolls, 29, is fluted or corrugated and the upper one is smooth and journaled in the free ends of an oppositely-disposed pair of springarms 31, as shown, whereby the upper smooth feed-roll, 30, is normally held in contact with the upper faces or edges of the strips offwood for assisting in feeding the same to the operation of the knives.

The shaft upon which the lower iiuted feedroll 29 is keyed is extended through its bearing in and beneath the longitudinal frame-bar 2 and is provided outside of said longitudinal bar with a spur gear-wheel The shaft to which the lower feed-roll 25 is keyed is also extended in a similar manner beyond its bearing in the central longitudinal fram e-bar and is provided with a spur gear-wheel 33 in line longitudinally with the gear 32. A gear-pinion 34 is mounted upon a short transverse shaft 35 intermediate the

gears

32 and 33, said intermediate pinion 34 intermeshing With and communicating motion tol both of said spur gear-

wheels

32 and 33. Mounted upon the same shaft with the spur-pinion 34 and keyed thereto is a band-pulley 36, from which a suitable. belt 37 extends to and passes around the pulley 7 on the main driving-shaft 4 of the inachine. Motion is thus communicated directly from the main driving-shaft to the shafts of the feed-rolls through the pinion 34 and gears 32 and 3,3, mounted on the shafts of said feedrolls.

rlhe rear spur gear-wheel, 33, has a pulley 37 lixedly connected therewith or keyed to the shaft on which said gear-wheel is mounted, and from said pulley a band 38 extends to and passes around the pulley 10 on the shaft of the lower feed-roll, 8, at the front end of the machine. Motion is thus communicated from the main iluted feed-roll 25 to the rear pair of feed-rolls, 8. Mounted upon the shaft of the spur-pinion 34 is a guiding and supporting roll 39, located immediately beneath the upper and front planer-block 21, by means of which the strips of wood passing through the machine are upheld at just the point where they are acted upon by the upper planer-block.

4,0 designates a sliding block or frame the width of which is approximately equal to the distance between the longitudinal frame-

bars

2 and 3, between which the feed-rolls are mounted. Said block 40 is adapted to slide vertically between two oppositely-disposed pairs of cleats or strips 41 attached to the inner adjacent faces of said longitudinal framebars. At the upper end said sliding block is provided With an oppositely-disposed pair of upwardly-extending arms, which are secured IOO IIO

IZO

at their lower ends to said blocks and adapted to receive between their upper ends an idlerroll 42, mounted loosely and adapted to revolve freely thereon. The lower end of said sliding block is provided with a pendent link or similar connection, which is connected to the inner free end of a spring-arm 43 secured to the frame of the machine at any convenient point. By means of the construction just described the roller 42 is held by springpressure against the upper faces or edges of the strips of wood just as they pass from the upper planer-block, thereby serving to direct said strips properly to the action of the rear planer-block.

In order to prevent the strips of Wood from wearing away, the inner faces of the longitudinal frame-

bars

2 and 3, between which they travel, are preferably lined or faced with metal plates or straps 44, which may be renewed from time to time Whenever necessary. A suitable guard or fender 45 extends over and upon the inside of the gear-

wheels

32 and 33 and the pinion 34, for the purpose of preventing the dust and shavings from getting into and between the teeth of the wheels, thereby clogging the same and rendering the machine inoperative. Said guard or fender is preferably made from sheet metal and is held in place by means of a thumb-screw passing through a perforation therein and engaging the frame of the machine. An additional guard or fender 46 is secured to the machineframe just above the upper front feed-roll 30 and close up to but in front of the upper Yplaner-block 2l, the object of such arrangement being to catch the shavings and prevent their too-forcible ejection from the machine.

The operation of the machine will be understood from the foregoing description, and it is therefore not necessary to enter into a detailed description of such operation. It may be stated, however, that the strips of wood or material to be operated upon are first inserted between the forward pair of feedrolls, being thereby carried inward and subj ected to the action of the upper planer-block. The material is then operated upon by the vertically-movable spring-actuated idler-roll 42, by means of which said material is properly directed between the main feed-

rolls

25 and 26 and thence t'o the action of the lower rear planer-block, against which the material is forced with any desired pressure by vibrating the frame 15 and depressing the roller 14, whereby the material is properly pointed and its thickness regulated. The material having now been operated upon on both sides is fed from the machine by means of the feed-rolls 8 and 9, located in rear of the lower planerblock.

The machine above described, while being designed especially for preparing riven wood for the purpose of making hoops for use in connection with tobacco-hogsheads, is also adapted to be used for planing or dressing narrow strips or boards upon both sides in a single passage through the machine, for any purpose whatever.

The machine will be found reliable and efficient in operation, durable and labor-saving in practice and thoroughly efficient and practicable for the purpose for which it is designed.

Various changes in the form, proportion and minor details of construction and arrangement may be resorted to without departing from the spirit or sacricing any of the advantages of this invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

l. In a hoop machine, a horizontal frame comprising several sets of longitudinal timbers arranged in parallelism and forming separate longitudinal spaces in which the operative parts of the machine may be mounted, the timbers of each set being arranged in different vertical planes and overlapping each other at their contiguous ends, in combination with a pair of horizontally disposed planer blocks, one mounted in bearings upon the lower longitudinal bars of each set, and another planer block mounted in bearings upon the other bars of each set, whereby said planer blocks are located in different horizontal planes and spaced apart longitudinally, a positively driven iiuted feed roll mounted in bearings in the machine frame and located intermediate the planer blocks, another feed roll superposed above the aforesaid feed roll, a pair of spring arms secured rigidly at one end to the machine frame and having the superposed feed rollj ournaled in their free ends, and adj ustable set screws having a threaded connection with the machine frame and underlying and upholding said spring arms, whereby the distance between said feed rolls may be regulated, as specified.

2. In a hoop machine, a horizontal frame comprising longitudinal timbers arranged in parallelism, in combination with a horizontally disposed planer head j ournaled in bearings upon and operating between said timbers, a bifurcated frame pivoted at a point intermediate its ends on the machine frame, a roller loosely journaled between the forked arms of said frame and upheld normally above andat a distance from the planer head, a lever forming a rigid extension of said bifurcated frame, and a vertically slotted cruciform guide bracket embracing said lever and having its lateral arms secured to the spaced longitudinal bars of the machine frame, substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I have hereto afxed my signature in the presence of two witnesses.
