Specification of Letters Patent, Patented Apr. 11, 1916.
Continuation of application Serial No. 12,887, filed March 8, 1915. This application filed September 17,
- v 1915. Serial No.51,22.
To all whom it may concern:
Be it known that I, JOHN N. HAHN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in Methods of Reinforcing a Board, of which the following is a specification, the principle of the invention being herein explained and the. best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.
M invention pertains to a method of rein orcing board material whether of indeterminate or measured length prior to putting it to some manufacturing purpose. The idea, as "feasibly exemplified in the drawings, comprises the affixing to, creasing and bending with an'artificial piece of stock of a metal member having prongs pr0 ecting therefrom. Preferably such prongs are struck-out and therefore integral tongues arranged according to some definite plan over the area of the member and all projecting in the same general direction. This allegedly novel conception of automatically afiixing reinforcement continuously across a board is of record in my copending applicationSerial Number 12,88 7, filed March 8, 1915. This application is therefore a continuation of the earlier application just identified, as to all matter common to the two applications.
- Accordingly, my method consists in automatically applying and since advisable also clenching a given length of strap-iron or other suitable metal area to a board" preparatory to employing the same as a part of some finished industrial product or pack age. Preferably the procedure is cont1nuous and progressively across or along the board. My invention effects a smooth con- 'tinuity or stretched application of a flexible metal reinforcing *strip of given length preparatory to -clenching upon a-fiexible paper or fiber board sheet of approximately like length. The advantages of neatness,
firmness and strength are attained in a manner not. possible where separate slats or boards are so reinforced. When the strapiron and board are both flexible, an association of,- the. two after the manner of this invention enables simple manufacturing expedients to impart the desiredconformation to'both at once by first creasing'and then 'view the invention consists of the novel combination of steps as hereinafter more speclfieally described and illustrated in the accompanying drawings, wherein is shown preferred and modified structural agencies,
but it is to be understood that changes, va-.
riations and modifications can be resorted to which come within the scope of the claims hereunto appended.
Figure I is a side elevation of a machine adapted to perform my method. Fig." II
is a top plan of one portion thereof- Fig. III is an enlarged broken detail showing two succeeding steps. Fig. IV is an enlarged section taken on line IV-IV of Fig. I. Fig. V is a plan of a piece of board material reinforced after the manner of my invention and also creased along predetermined lines. Fig. VI is a fragmentary section I on line of Fig. V. Fig. is an enlarged section taken through the "middle of Fig. V. Fig. VIII is a similarly enlarged bottom plan of a portion of Fig. VII. Fig. IX-is a perspective view of the board shown in Fig. V after the same has been bent up as determined by the creases thereacross. Fig. X is a side elevation of a simplified modification for performing only the concluding operations.
Fig. XI is an enlarged section on line FIT- XI of Fig. X. Fig. XII is a view corresponding to Fig. XI similarly enlarged and showing the reinforcing member itself reinforced. Fig. XIII is a viewcorresponding to Fig- V showing a reinforcing member of different shape applied to a board.
Advertingnow to the drawings in order i to better understand the following description of the arrangement and operation thereof, it is stated at the outset that Fig. I illustrates a mode of practising, as a continuous operation of a single machine, the
. steps required to fashion three metal strips M ofindefinite length with metal prongs P and thereaftersuccessively applying the same along fiber board material B having a limited range of flexibility, next causing the prongs to enter and penetrate, then clenching Jthe tips ;0 thereof and finally creasing and scoring-up as required in the making of boxes, and as appears in Figs. V and VI and IX. Fig. I is furthermore shown as applying reinforcement to a series of separate boards'B which have been cut to a specific size suited to some particular kind and shape of box. I would have it clearly understood that I do not limit myself in any way either to the kind of board material or vto the manner in which it is supported or moved along. Nor have I any reason to believe that the prior art whether inerely practised or patented as well compels me to limit the scope of this application to any specific character of pronged reinforcing member or the manner of its automatic ap-' plication to the board material that may have been selected.
The preferred type of machine as I have constructed and successfully operated it comprises three pairs of standards 1, 2 and 3'supported in an elevated position in any suitable manner thereby and a feed'table 4 having its advanced end beveled underneath at 5 near the standard 3. Anothertable 6 is supported in some feasible manner beyond the standard-3 and has that end which is nearest the same likewise beveled at 7 Supported in an inclined positionbetween the standards 2 and 3 is another feed table 8 provided above with three longitudinally a space therebetween of sufficient size for the passageof the boards B. The latter are,
caused to move along the table 4 by means 'of a pair of feed rollers 11 adjacent the standard 1 and another pair of feed rollers each designated as 12 and adjacent the standard 2. The distance between the roll ers 11 and the rollers 12 is such that a particular board is always fed along by either one or the other in a well known manner. The upper ends of the pair of standards 1 are fashioned as bearings suited to support the shaft l3 e f'a large roller l l upon which three rollers 14 are mounted. Each of these rollers has wound uponit an indefinite 1 length of metal strips M commonly known duplicated parts of the machine as perform successive operations upon or in the handling of the strips M will be employed.
The standards 2 support in a suitable upright guide-way a journal box 15 in which the shaft 16 of a rotary member 17 having a series of peripheral dies 18 moves. conformation of these dies is clearly seen in Fig. IV. Superposed above the journal box 15 is another journal box 19 which receives the shaft 20 of a rotary member 21 having peripherally projecting punches 22 which are similarly spaced as the dies 18 and adapted to project therein as appears in both Figs. 1 and IV. The elevation of the journal box 19 may be adjusted by means of a manually operable screw 23 which passes through a top cross-bar 24 and supports such box. This punch and die mech' anism is adapted to strike-out the prongs P of the shape seen in Fig. XI, and progressively so, along the strips M by a continuous andpositive action which may be presumed. v
The standards 3 likewise support in suitable guide-ways a journal box 25 adapted to mount the shaft 26 of a plain metal roller 27 the uppermost surface of which is substantially level with the top of the tables 4 and 6. Higher up the standards 3 similarly support a journal box 28 adapted to mount the shaft 29 of another metal roller 30 the lowermost surface .of which is to be spaced a distance from the roller 27 corresponding to the combined thicknesses of the'particular board material B and the reinforcing member M which have been selected. The control of the spacing between the rollers 27 and 30 is similarly accomplished by means of a screw 31 passing through a bar 32 and adapted to carry the journal box 28. It is of importance to notice the arrows which indicate the direction of rotation of the rollers 27 and 30. Any feasible power connection for driving the rollers 27 and 30 will answer and therefore need not be and has not been shown. Beyond the standards 3 ma position below and'above the table 6 are opposed male and female creasing rollers 33 and 33 respectively which are purposed to impart creases to the finished product in the fiat along the four lines 6 in the board and the superimposed four'lines m across the strips, preparatory to scoring-up along such creased mes.
The operation of the machine is as fol- The lows: The speed of travel of the boards B and the reinforcing member M having'been adjusted to correspond to the strip-M as it is unrolled and drawn forwardly between the punch and die is subject to the operationpfhaving pointed prongs struck-out at intervals along the middle thereof. Thereafter it passes downwardly along the table 8 the prongs P in the meantime moving through the channels 9 to converge toward the most advanced of the. boards B. The
tips 10 of the prongs will begin to penetrate and enter the board some little distance prior 'to passage between the narrowest space between the rollers 27 and 30 as clearly appears in Fig. III. Thereafter the prongs progressively penetrate along their" own length through the board B to be finally bent backwardly or clenched against the under surface of the board at the narrowest.
point. The completion of such final afiixing operation is likewise clearly seen in Fig. III and is the more eifectivelyiaccomplished owing to the rotation of the roller 27 in opposition to the direction of travel of .the stock; An inspection of FigsuVII and VIII which have been copied from my earlier application filed March 8, 1915, Serial Number 12,887, discloses the appearance of board material reinforced by a continuous metal strip having integral prongs penetrating therefrom a and clenched there against by machine operation. In this connection mention is made that ,Figs. V and IX are also copied from the same application'just identified and are again shownin this application in order to r'emphasize the manufacturing objects and practical utility of the subject matter of this application.

I claim: 1
I '1. The method of reinforcing I a fiber board, which consists in presenting thereto a pronged metal member while both' the board and member are under tension such that the prongs of the member projecttoward the board, and exerting a compressive i force'to cause the prongs to become clenched in stretched relation upon the board, whereby to effect acontinuously smooth, taut and permanent application of each to the other.
2. The method of reinforcing a flexible fiber box blank, which consists, in 'progrese sively applying integral prongs of a metal member in stretched continuity along said board while both blank and member are causing the maintained under tension,
prongs to penetrate and become clenched to ,said blank, and finally creasing "said board and strip' together whereby uniformly to span both locally. j
