MACHINE FOR MAKING PAPER BOXES.

@be Stimuli numb tu in tlgtst tetttrs @that nn uniting part at tigt time TO ALL WHOM I'll MAY CONCERN:

Be it known'that- I, CHARLES B. lIA'rrInLD, of the city and county of Philadelphia, Vin the State of Pennsylvania, have invented a new and useful improvement in Machinery for Making Paper Boxes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which make part of this specication, and in which- Figure 1 represents a view in elevation of one sideof a machine embracing my improvements.

Figure 2 a similar view of the same at a right angle to fig. l; and

Figures 3, 4, and 5 are views ofthe details of the head-holder.

It is the object of my invention to facilitate the finishing of paper boxes (partly formed by hand) by means of mechanism which will perform the work of applying and smoothing the covers used to strengthen and ornament the box.

In the accompanying drawings, which show a convenientarrangement of mechanism for carrying out the object of my invention in boxes having plane sides and tops, such as collar-boxes, a receiving or holding-chuck, A, is mounted on one end of a shaft, I, supported in proper bearings, and driven by a gear-wheel, J, rotated by a crank, II, or other suitable means. This gear-wheel drives a corresponding pinion, N, on a shaft, O. .lhis shaft carries a drum, P, around which hands or cords pass to drive the other portions ofthe mechanism through a. suitable system of pulleys. A rotating brush, B, is carried on a shaft, R, mounted in suitable bearings in the frame` and arranged at right angles to the chuck-shaft I, so as to revolve above and within the circumference ofthe chuck, as shown in the drawings. A smoothing-brush, C, is mounted on an inclined shaft, S, turning in bearings in a frame, T. This brush, it will be seen, is arranged on the in ner side ofthe chuck, and below it and the brush B, itsshaft S being in the same vertical plane as the shaft R, but inclined at an angle of about forty-five, degrees. The shaft is mounted in a frame pivoted at s, so as to be adjustable nearer to or farther from the chuck, to accommodate boxes of varying sizes. The brushesV are rotated by handelend pulleys from the drum. An oscillating frame or lever, D, is pivoted to the frame by hinges d, so as` to vibrate towards and from the chuck A, being provided with a spring, G, to throw it outwards, and a cord,'K, and treudle to dranr it inwards. The upper end of this lever is furnished with apad, E, of velvet, chamois leather, er some similar material, upon which to place the cover of the box. This pad is surrounded by a ring, F,tting loosely around the pad and supported upon springs f, for a purpose to be hereinafter described. v

The operation of the machine is as follows: The box to be covered is placed on the chuck A. The cover forthc head (having tirst been properly glued or pasted) is placed on the pad E with the glued side towards the chuck. The pad is thc-n pressed against the box on the chuck A. by means ofthe cord and trcadle. The springs flift the edge ofthe ring I" above the pad and hold the pasted head securely. When, however, thc pad is` forced against the chuclc,`the ring F yields and permits the glued cover to be forced upon the head. With the pad still pressed againstithe chuck, the operator now takes a strip of paper, properly glued or pasted, to form the covering'for the` side of thebox and sticks one end upon the box on the chuck, the outer odge next the pad being flush with the head ofthe box, while 'the inner edge projects slightly beyond theside of the box. The chuck is now rotated in the direction shown by the arrows, the work-man smoothing the cover of the sides with his hand, while the friction of the pad smooths the head. Asthe box revolves the brush B turns down and under the edge ofthe box the projecting edge of the covering paper, while the brush C, which revolves within the open end of the box, turns in and smooths the edge thus turned by the other brush on the inner side of the box. This gives a perfect finish to the edge. When the box is finished the treadle is released, and the pad thrown back by its spring G. Thefnished box is removed from the chuck and a new one put on, and the former process is repeated. i

What I claim as my invention, and desire to secure-by Letters Patent, is-

1. The combination, substantially as described, of the cover-pad or receiver E with the yielding ring F, for the purpose set forth.

2. The combination, substantially as described, of the holding chuck, vibrating pad, and yielding ring, for the purposes set forth.

3. The combination, substantially as described, of the holding chuck A, turning brush B, and smoothing brush C, for the purposes described.

4. The smoothing brush G, arranged on an inclined adjustable shaft, as and for the purpose described.'

5. The combination, substantially as described, in a machine for making paper boxes, of a vibrating pad, a chuck projecting beyond its supporting frame and rotating in a ixed position, a brush to turn down the inner edge of the cover, and an auxiliary smoothing brush revolving inside the box, for the purpose of finishing the covering of the box without removing it from the machine.

6. A revolving brush, for turning down the edge oi' the covering paper, substantially in the manner described.

7. A brush, rotating within the box substantially as described, for the purpose of smoothing thc turneddown edge of the paper. i

In testimony whereof I have hereunto subscribed my name.
