GEORGE A. GAGE, or CHICAGO, ILLINOIS.

VENEER-COILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 592,110, dated October 19, 1897,

' Application filed March 15, 1897. Serial'No. 627,583 (No model.)

To all whom it may concern:

Be it known that I, GEORGE VA. GAGE, a

' citizen of the United States, residing'at Ohismall an interval as possible, and in which no great exertion of strength is necessary on the part of the operator.

To this end myinvention consists in the peculiar construction, arrangement, and combination of parts, and especially in the mechanism employed for operating the presser-roll and sheath, all as'more fully hereinafter described and claimed.

In the drawings, Figure 1 is a front. elevationof my machine. Fig. 2 is a cross-section on line m 00, Fig. 1. Fig. 3 is ahorizontal section' on line g] y, Fig. 1. Fig. 4isan elevation of theilatch employed'for'holding the parts in normal position. Fig. 5 is a section similar to Fig. 2, illustrating the operation of the machine.

A is a suitable frame, in which is journaled the shaft B, carrying the collapsible drum 0.

D is a friction-pulley on the shaft B.

E is a drive-shaft arranged -parallel to the shaft B,"having a friction-pulley F, adapted to be moved in or out of contact with the pulley D by a suitable controllinglever. (Not shown.) Y

The drum 0 comprises two segments a b, hinged together, the segment a being secured to heads fixed upon the shaft B.

G are gear-segments sleevednpon the shaft B and carrying the cams 0, adapted to bear on the blocks d in the segment b.

H is a shaft journaled in bearings within the drum and upon'which are secured the gear-segments I, meshing with the segments G. The endof the shaft H projects out beyond the end of'the drum an'd'is provided with anoperating-handle I-I,' all so arranged that by turning the handle H in one direction the drum will be collapsed, while by turning it in the reverse direction the drum will be thrown into its cylindrical form.

J is a'flexible jacket or sheath surrounding the drum 0, and attached on its front side to the arms K, the latter being adjustably secured to arms K, extending up from the base of the machine. The rear side of the sheath is secured to the arm L, to which is attached the rope or flexible connection L, passing upward and over the pulleys L a weight L being secured to its free end.

Mis a presser-roll journ'aled in a frame N,

which is slidingly secured to upward extensions A of the frame above the drum 0.

O is a lever fulcrumed at one end to a post A on the frame A bearing in the frame N.

O is a weight at the free end of the lever O. 'P is a lever above the lever 0, connected thereto by the link P and-fulcrumed in-tlie post A on the frame.

; Q, is aslotted lug'or fork on the lever P, adapted to engage with a dog R on the flexible connection L.

S is a latch-hook on the frame with which the freeend of the lever P is adapted to engage in its depressed position, the parts be- -ing so arranged that'by depressing the lever P the weighted lever 0 will be lifted, carrying up with it the sliding frame N and presserroll M, but upon releasing the lever P- the weight 0 will carry down the 'roll M, pressing it against the drum 0.

T is a presser-bar beside the roll M, having the upwardly-extending shank T slidingly secured inbearings T on the frame N.

T are springs tending to lift the bar, and

T is a cam-lever pivoted to the frame N,

adapted when operated to press the bar'T downward.

U is a shaft journaled in bearings at the base of the machine, permitting of a slight lateral movement of the shaft.

U is a friction-pulley on the shaft U, and E is a friction-pulley on the shaft E opposite the pulley U.

V is a lever pivoted to the base and adapted and pivoted with a slotted to move the shaft U to press the pulley U into contact with the pulley E.

IV is a drum on the shaft U, to which is secured a flexible connection \V, passing upward and attached to the lever I.

The parts being constructed as shown and described, the operation of the machine is as follows: The veneer strip is engaged with the drum 0 by placing its end underneath the segment Z1 and over the edge of the segment a, which is provided with a series of sharp points to prevent the veneer from slipping. The drum C is then started to revolve and at the same time the lever P, which is within easy reach of the operator, is disengaged from the hook S, allowing the weight 0 to force down the presser-roll M against the veneer. This will also carry the fork Q out of engagement with the dog R, allowing the weight L to draw the sheathing J tightly against the veneeras it is wound around the drum. After the coil is complete the operator moves the cam-lever T so as to depress the presser-bar T, pressing down the end of the coil, so that it may be nailed to the layers below. He then moves the lever V with his foot, so as to bring together the friction-pulleys U and E, which causes the shaft U to revolve, winding up the flexible connection IV on the drum W, and pulling down the lever P until it engages with the latch-hook S. This will raise the presser-roll N and release the sheath J, after which the drum may be collapsed by turning the handle II, as before described, and the coil slipped off from the end of the drum.

It will be noticed that in the operation of the machine it is unnecessary for the operator to chan ge his position,as all of the controllinglevers are within easy reach, nor is it necessary for him to exert any physical strength in the operation, a slight pressure being sufficient to actuate the levers. Again, it will be noticed that the presser-roll M and sheath J are simultaneously actuated both in applying pressure and in releasing. For these reasons the operator is enabled to work much more rapidly than is possible with machines heretofore in use, where it is necessary for him to lift heavily-weighted levers and change his position to operate the various parts of the machine.

hat I claim as my invention is- 1. In a veneer-coiling machine, the combination with a collapsible winding-drum, a flexible surrouriding-sheath therefor, and a presser-roll of mechanism for simultaneously actuating said roll and sheath to apply pressure to the work when coiling, and to release the same.

2. In a veneer-coiling machine, a collapsible winding-drum, comprising a shaft, a segment fixedly secured thereto a movable segment hinged to said fixed segment, gear-segments hinged on said shaft carrying cams, pressing against bearings 011 said movable segments, a shaft journaled within said drum, gear-segments thereon meshing with the gear-segments on the main shafts and an operatinghandle on said second shaft extending out from the drum.

In a veneer-coiling machine, the combination with a frame, a collapsible windingdrum journaled therein, and a surrounding sheath therefor, of a frame vertically, slidingly secured to said main frame above said drum, having a resser-roll j ournaled therein, a weighted lever for depressing said sliding frame and roll, a weight for contracting said sheath around said drum, and power-actuated mechanism for simultaneously lifting said weights.

4. In a veneer-coiling machine, the combination with a frame, a collapsible windingdrum journaled therein, and a surrounding sheath therefor, of a frame, vertically, slidingly secured to said main frame above said drum having a presser-roll journaled therein, means for raising and lowering said sliding frame, a presser-bar beside said prcsser-roll slidingly secured to said sliding frame, springs for normally raising said presser-bar and a lever for depressing the same.

5. In a veneer-coiling machine, the combination with a frame, a collapsible windingdrum journaled therein, and a surrounding sheath therefor, of a frame vertically, slidingly secured to said main frame above said drum, having a presser-roll journalcd therein, a weighted lever for depressing said sliding frame, a weight for contracting said sheath around said drum, a power-driven windingdrum, a starting and stopping lever therefor, and a flexible connection secu red to said drum adapted when wound thereon to lift said weights.

In testimony whereof I ailix my signature in presence of two witnesses.

GEORGE A. GAGE.
