IMPROVEMENT IN BARREL-MAKING MACHINES.

Specification forming part of Letters Patent No. 209,349, dated October 29, 1878; application filed March '7, 1878.

- To all lwhom it may concern:

Be it known that I, JOHN D. MOEACHERN, of the village of Harriston, in the county of Wellington, Province of Ontario, Canada, have invented certain new and useful Improvements in Barrel-Makin g Machinery, of which the following is a specification:

The object of my invention is to provide a-n eflicient machine for the rapid manufacture of barrels and cheese-boxes, made out of veneer 5 4and consists of a hollow cylinder driven by peculiarly-arranged gearing, and carried within a frame 'provided with circular saws and other mechanism necessary to form and produce the aforesaid barrels with the least amount of manual labor, substantially as hereinafter described.

In the drawings, Figure 1 is a sectional side view 5 Fig. 2, an end view; Fig. 3, a plan of a machine embodying my improvements. Figs. 4, 5, 6, 7, 8, 9, l0, and ll are details of the working parts.

A is the frame, made of wood or any other suitable material. B is a hollow sheet-metal cylinder, hereinafter more particularly `described. t

C is the shaft or axle of the cylinder, carried in the bearings O1, C2, and O3. This` latter bearing is upon the hinged support Ai, which folds down in order to allow the barrel, when formed upon the cylinder B, to be withdrawn therefrom, as hereinafter described. Vhen the machine is `specially made for the manufacture of cheese-boxes the cylinder B is much shorter than shown in drawing, in which case the support A1 is dispensed with.` l

l) is a table upon which the sheets of Vveneer are placed and guided into the machine. E E are arms hinged to the uprights AA2, and supporting the pressure-bar F and rollers G, H, and I. J is a treadle for the purpose of operating the arms E E, to which it is connected by the rods K K. L isa swinging saw-frame, attached to and placed within the y frame A, as shown. M is a double-ended sawmandrel. N N are sleeves for holding the saws Nl N1. These sleeves slide upon the mandrel M, but are prevented from revolving ing angular grooves p p cut in its face. Into these grooves the inner ends of the rod O O t. Consequently, as the other ends of these rods fit into grooves cut in the sleeves N N,

the said sleeves, which hold the saws Nl N', may be brought closer together or pushed farther apart by simply moving the sliding block P u p or down within its frame, as may be understood by reference to drawing, from which it will also be noticed that the set-screws P can be so adjusted that by stopping the block P the saws Nl Nl are prevented from going farther apart than may at the time be desired, while the weight of the block P is sufcient to force them apart until the said block butts against the setscrew. By this .arrangement the distance between the two saws is easily regulated either when the machine is in motion or at rest. The saw-mandrel M is driven by the belt N2, which connects the said mandrel to the main drivingshaft Q, as shown.

It is a large spur-wheel, loose upon the axle y or shaft C, but held to the face-plate R by the nut and bolt r, as shown. This face-plate is keyed to the shaft or axle C. The spur-wheel R gears into the pinion S, which is loose upon the shaft Sl, but may be connected thereto by the clutch S2.

T is a spur-wheel, the same size as R, but keyed to the shaft S1. This spur-wheel gears into the spur-pinion T1, which is keyed or otherwise fastened to the sleeve V, which revolves upon the axle CL V1 is a pulley keyed to the sleeve V. V2 is a larger pulley, loose upon the same sleeve, but fitted with dogs V3, which engage with the pinion T1, causing the said sleeve to revolve. Y is the belt connecting the pulley Vl to the main shaft Q, and Yl is the belt connecting the pulley V? to the same shaft. X is a belt-tightener, operated by the handle X', iand intended for tightening the belt Y, which would otherwise slip upon the pulley V1.

From this description, and fromreference to the drawing, it will readily he understood that by putting the gearing in motion the cylinder' B will revolve, provided the pinion S is clutched to the shaft Sl. When the belt Y is not tightened by X the other belt, which should always be kept tight upon the pulley V4, drives the machine as the dogs V3 catch in the recesses T2 on the pinion T1; but when the belt Yis tightened upon the pulley V1 the sleeve V is made to revolve faster than the pulley V2, thus clearing itself from the the dogs V3.

S3 is an axle-box for holding one end of the shaft S1. This box is adjustable, so that the pinion S can be thrown out of gear, as hereinafter described.

The cylinder B is made ont of one piece of sheet metal, fastened to and supported by the spiders Bl B1, placed at each end thereof, as shown.

B2 is an eccentric-shaft, held by the boxes b b. The arms b1 b1 connect this shaft to the rim of the spider, which is divided into segments, as shown. Byturning the handle of the eccentric shaft B2 the segment of the spider to which the arms b1 b1 are attached, together with that portion of the cylinder connected thereto, can be expanded from or contracted toward thev center of the cylinder, whichever may at the time be desired, in order to open or bring together the edges of the cylinder, which overlap each other at B3.

d d are set-screws passing through lugs d3 d on the rings d d, which, by acting against the knees d2 d2, contract the diameter of the cylinder to a limited extent, for the purpose hereinafter specified. 4

As the spaces between the two edges which overlap each other at B3 may not be sufficient for its purpose when the cylinder is thus contracted, packing underneath the boxes b b can be removed and the said boxes correspondin gly drawn to the center, orvice versa, as the case may be.

Having now pretty fully described the construction and arrangement of the machine, I shall proceed to explain the action and operation thereof.

Having arranged the sheets of veneer at a convenient distance in the rear of the machine, and the operator, standing at that point, places a sheet thereof upon the table D, pushes it under the pressure-bar F till it enters the space at B3 in the cylinder B, as shown. The handle of the eccentric-shaft B2 is then turned, and the edges brought together gripe the sheet between them. The machine is now started, and as the cylinder B revolves the sheet of veneer is wrapped around it. When the cylinder B has completed a revolution it is stopped by an automatic arrangement, and the edges of the veneer, which now overlap yone another, are nailed by an operator, who

stands in front of the machine, the nails being driven by him between the teeth of the pressure-bar, which permits their being driven very near to the edge of the sheet of veneer, and are clinched by coming against the metallic cylinder B. The grain in this piece of veneer runs with thc circumference of the cylinder.

Before putting on the outer skin the operator causes the saws N1 N1 to move toward each other till they come opposite the grooves b4 cut in the cylinder, when he presses forward the saw-frame and trims off the rough edges of the inner skin.I The grain of the outer skin rims lengthwise, and is put on in segments in the same way as the first, except that the edges butt against each other and each segment is nailed to the inner skin, all the nails being clinched by coming against the metallic cylinder B, which is, as I have said before, made in one piece. The hoops are also put on in the same way by passing underneath the pressure-bar F.

f f f j' ff are collars upon the roller H, and are adjustable thereon. These collars are for the purpose of guiding the hoops and keeping them at the proper distance apart.

In order to keep the hoops clear of the veneer upon the table D, I pass them first over the roller G. rIlhey then pass beneath the roller H, between the collars ff f j' f f, and then beneath the pressure-bar F, which is supported by the roller I, resting upon the veneer or whatever may be passing thereunder.

When it is desired to have additionalpress ure upon the veneer passing beneath the roller I, the operator at the front of the machine presses down the treadle J.

The circular saws N1 Nl having been adjusted the proper distance apart, upon their mandrel, the operator who feeds in the veneer presses forward the saw-frame L till the said saws, which, of course, at the time are revolving, come in contact with the rugged ends of the veneer, cutting them cleanly off.

When the barrel has been finished it will be found to fit the cylinder B rather tightly; and, in order to loosen it therefrom, I contract the cylinder B by means of the eccentric-shaft, leaving the barrel loose, except the end of the sheet, which is still held between the edges of the veneer nailed together. I then bring down the dog F', one edge of which is hinged to the pressure-bar F, into the barrel, and, by starting the cylinder B in motion, it soon works itself loose, when the barrel may be withdrawn over that end of the cylinder supported by the hinged support A1.

I have already mentioned that the cylinder B is stopped automatically, the attachment for this purpose consisting of a small roller, 5, held at the end of the stoppin g-bar 6, which slides upon the frame A, and is under the command of the operator at the front of the machine.

In order to stop the cylinder B exactly at the point desired, the operator referred to slides the stopping-bar 6 from him till the roller 5 is in front of the rim of spur-wheel It, upon which projects the stop 7. When the stop 7 reaches the roller 5 the latter presses it in, which action causes the hinged bar 8 to project from the other side of the rim of the aforesaid spur-wheel, and when this stop 7 comes in contact with the collar 9 upon the shaft S', which ,bein g held, as before mentioned, in the box Sis pushed out of its former position, and thf' spur-pinion being thus thrown out of gear, the cylinder B stops instantaneously, as desired. l

The bent lever 10, with a weight, 11, hung upon it, is arran'ged, as shownfor the purpose of forcing the box S3 back into its former position after the catch-bar 8 has passed the collar 9.

The semicircular support 12, held upon the upright 13 and operated by the lever 14, as shown, is for the purpose of supporting the heading when the machine is used for making cheese-boxes.

15 is a ring, made in halves,hinged together at one connection and at the other held by a set-screw, as shown. This ring is bored out taper or cone shape, and is intended for the purpose of contracting the ends of bulge barrels.

The arrangement described for the purpose of contracting and expanding the cylinder B is for the purpose of slightly altering the diameter of the barrels when necessary, in order to accommodate them to the size of the heading, which sometimes varies in diameter.

Vhat I claim as my invention is- 1. The hollow cylinder B, supported upon the shaft C by the divided spiders B1 B1, and made from one piece of sheet metal, as described, in combination with the eccentric-shaft B2, boxes b b, and arms b1 b1, set-screws d d, the lugs d3 d3 on the rings dl dl acting against the knees d2 d2, arranged and operated substantially as and for the purpose specified.
