SPECIFICATION forming part of Letters Patent No. 623,862, dated April 25, 1899.

Application filed January 14, 1898.

To all whom it may concern:

Be it known that I, EZRA A. ARMSTRONG, a citizen of the United States, residing at Samaria, in the county of Monroe and State of Michigan, have invented certain new and useful Improvements in Machines for Making Paper-BOX Blanks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will ro enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in machines for cutting paper-box blanks; and the object thereof is to provide a simple con- I 5 struction of machine which is effective in operation and by means of which paper-box blanks may be formed with great rapidity and accuracy.

A further object is to provide an improved device for disengaging the blanks from the dies after they have been formed thereby.

With the above objects in view the invention consists in the novel combination and arrangement of parts which will be fully set forth in the specification, particularly referred to in the claims, and illustrated by the accompanying drawings, in which- Figure l is a perspective view of a machine embodying my invention. A Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a vertical transverse sectional view of the machine, taken longitudinally through the die carrying and feeding rollers. Fig. 4L is a sectional detail view of the die-carrying roller, showing a portion of the material from which the blank is formed engaged thereby and the ejeeting devices for removing the blanks from the dies.

Referring to the drawings, A designates the table of the machine, supported at its respective ends by the legs B and formed at one end with an opening O.

J ournaled in bearings D, carried by one of the pairs of supporting-legs B, is a shaft E, having one of its ends projecting beyond its bearing and carrying a belt-wheel F. Secured to said shaft is a roller G, of wood, iron, or other desired material, having a covering G', of hard rubber or similar material, said roller moving in the opening O ofthe tableand constituting a feeding-roller.

Serial No. 666,674. (No model.)

II are U-shaped spring-arms which are secured at one end to the upper surface of the .table at opposite edges thereof and carrying at their opposite ends the journal-boxes I, in which the shaft J is mounted. A hollow cylindrical roller K is secured upon said shaft, said roller having closed ends, as illustrated. Through the medium of the spring-arms the roller is yieldingly held and constitutes afeed- 6o ing-roller to coact with roller G. Secured upon the roller K are the dies L of the proper contour to out a blank of desired form, said dies being arranged in pairs, and in the present instance there are two pairs, one pair on each side of the roller. Positioned on the table at the opposite end of the machine are the arms M, which support the roll of pasteboard N, from which the blanks are to be out. The combined die-carrier and feeding-roller 7o K is held in contact with the feeding-roller G through the medium of said spring-arms H, and when the end of the pasteboard is placed between said rollers and the roller G revolved through the medium of a belt from some motive power engaging the belt-wheel carried by the shaft of said roller the pasteboard is fed through said rollers, while at the same time the die-carrier is revolved and the blanks formed by the dies.

For expelling the blanks from the dies after they have been formed I provide the springfingers O, which are secured at one end upon the interior of the die-carrier and are thence bent to form spring-loops having straight por- 8 5 tions P, which extend through opening Q in said roller and openings Q in the dies and normally project into the space inclosed bythe walls of said dies, said iingers having heads or pads R at their extremities. When the 9o dies engage the pasteboard and out the blank therefrom, the fingers are pressed backwardly into the hollow roller; but as said roller revolves and disengages the feeding-roller the spring-fingers return to their normal positions and press the blank from the dies.

From the above description it will be seen that I have produced a very simple construetion of blank-cutting machine having a combined feeding-roller and die-carrier and also roo an automatically-operating ejecting device for disengaging the blanks from the dies, the

machine being very effective in operation and capable of rapid manipulation.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is

l. In a machine for cutting paperbox blanks, the combination of a supportingframe, a roll-holder carried thereby, a driven feed-roller journaled in the frame, a hollow die-roller yieldingly supgorted upon the frame and actuated solely by frietional engagement with the feed-roller, a blank-forming die upon the periphery of the roller, and spring-iingers secured upon the interior of the die-roller and normally extending through openings formed therein and carrying pads or heads at their extremities projecting into the space inclosed by the die, substantially as described.

2. In a machine for cutting paperbox blanks, the combination of a table provided with au openingin one end thereof, a driven feed-roller moving in said opening, U -shaped spring-brackets arranged on opposite sides of the table and having their lower arms secu red thereto and their upper arms provided with bearing-boxes, a transverse shaft mounted in said boxes, a hollow roller mounted thereon and actuated by frictional engagement from the feed-roller, a die carried by the hollow roller, and spring-fingers secured upon the interior of said roller and normally extending through openings formed therein and projecting into the space inclosed by the die, said fingers being adapted to eject the blanks as they are formed,substantially as described.

3. In a machine for cutting paper-box blanks, the combination of a supportingframe, a driven feed-roller, a holle7 dieroller yieldingly supported on the frame and driven from the feed-roller, a die on the periphery of the hollow roller, and spring-iingers each secured at one end upon the interior of the hollow roller and thence bent to form a spring-loop and having its free end projecting through a slot formed in the periphery of said roller in the space inelosed by the die and carrying a pad to push the blank away from the die, substan tiallyas described.

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