The shoulder portion i has a represent invention will appear from the more deduced end, the sides of the shoulder portion 55 having been cut away to provide such reduced portion 6. and to produce diagonally formed ledges I, I, extending at their outer ends 8 to substantially horizontal position to form a seat;
'Theopposite end of the base member I carries a recess 9 adapted to receive the impaction memher or die it. which may be welded in position. or held in place by removable elements, such as bolts, etc., 'or in any other desired way. For example, the side walls of the recess 9 may be given a slight draft and the die Ill provided with side walls'having a coacting draft, so that the die Ill may be slipped into position in the recess 9.
An impacting or percussion arm ll, provided with side walls or webs i2, i2 produces a substantially U-shaped' arm, the space between the side or web portions l2, I! being suilicient to enable 'the arm to be placed over the reduced end I of the shoulder portion 4 of the base I. Perforations. l3 near the end of each side wall l2, II, are adapted to aline with a perforation l4 in the reduced end portion 6 of the projection 4 of the base I, and a bolt l5 passed through the perforations I3, I 3 on the arm II, and the per- !oration l4 on thereduced portion 6 serve to hold the arm in position with respect to the base member, the ends of the bolt l5 desirably being swaged over to prevent separation of the parts or their working loose. Any other means of securing the members together may, of course, be
utilized other than the bolt referred to.
One end [6 of the arm Ii forms a wall portion closing the U-shaped channel in the arm I I, and serves also to hold the spring manber in position. In the normal retracted position of the,
arm II, the lowermost edge I! of the end wall l6 rests against the seat 8 on the projection 4 of the base portion I. To maintain the arm in such normally retracted position, a spring l8, which may be of the ordinary leaf ype. is positioned within the U-shaped channel of the arm ll, one end I! of the spring being placed in the recess 5 of the projection 4 on the base I, while the other end rests against a stop formed on the inner surface of the arm member I I, the reduced end portion 6 on the projection 4 of the base I ooacting with the wall portions of the arm member ll, preventing displacement of the spring. The spring I8 normally tends to hold the arm portion in retracted position as shownin Figure 1 with respect to the base portion i.
The other end of the arm II is desirably provided with a head portion 2| having a recess 22 for reception of a die or impaction member 23,
'which may be secured in position in the head member 2| in a manner strictly analogous to that described above for the die member II. The die "members I0 and 23 are mounted so that their respective toothed portions 24 and 25 intermesh when the arm II is given an arcuate motion downward about the pivoting bolt is. A hand portion 25 may be mounted on the head portion 2| for receiving the impact from the hand for operating the device.
As illustrated, the die members i and 23 are desirably provided with toothed portions 24 and II respectively, adapted to intermeslabut any other form of intermeshing elements may be utilized. The toothedmembers are simple to produce, and produce an effective result; The teeth, asshown inFigures4to 9,maybeoi.' relatively sharp contour and of a depth so that upon impaction of the two die members (upper and lower) together, the fibers of the flexible material, or oi the metal, are distorted suiliciently to interamazon bind the sheets together-but the depth or Spacing of the teeth should not be suflicient to cause tearing or other mutilation of the flexible material. The upper and lowerdies, such as ll and 23, are mirror images of each other, so thatthey will intermesh when brought together. As shown in Figures 4 and 7, such die members, the lower die only being illustrated, may take the form of a base portion having a projecting rack portion 3i carrying the teeth 24 having rounded or bevelled corners 34. These dies. however, may be given any shape or contour desired to produce a corresponding variation in e t e of impacted area on the flexible sheets, and ti.
may, for example, be given any geometric figure,
letter or numeral configuration, among which may be mentioned an annulus, circle, crescent, triangle, square, etc., or any desired letter or numeral. Illustrating the variation in the form of toothed surface that may be utilized in this connection, Figures 5 and 8 show a die member I0 having toothed members 24', in which the teeth are serrated, as shown at 32. The die 10" member of Figures 6 and 9 shows the toothed members 24" arranged in the form of the letter A. Of course, a series of letters may be placed on the die, if desired, or a series of numerals utilized in this way to identity letters or papers or other flexible sheets-coming from a particular origin. And if desired a series of diilerent dies may be utilized with anyparticular device constructed in accordance with, the present invention.
The device is readily assembled. the arm being placed in position over the base member and held thereto by means of the pivotal bolt ii. In use the superposed sheets of flexible material may be placed in the space between the die members II and 23 when the device is in the normal retracted position shown in Figure 1, and then by an impact or percussion blow against the handle portion 26, the dies are forced together to produce an impaction in the flexible material, and to cause the latter to hold together. The arcuate motion of the head member 2| carrying the upper die 23 serves to localize the impaction or percussion, and to accelerate the binding of the papers together.
The elements, such as the arm and base, may be made from any desired metal, and either as castings, die castings or metal stampings, bars, etc. The position of the pivotal bolt i5 may be utilized to determine the arcuate movement of the arm II and the upper die 23, and raising or lowering the position of the bolt or pin l5 will increase or reduce the arc of moving and the lmdercutting which is obtained, permitting adjustment depending on the number of sheets of material to be bound together, or the thickness or degree of toughness of such sheets, etc.
Since the sheets are bound together by the percussion or impact delivered to the hand poridon 24, the degree of binding of the sheets may .be determined by the force of the impacting blow. If it is desired to bind the sheets together only temporarily, a lighter blow will be suflicient to hold the papers together, enabling them, however, to be separated when desired without destruction of the flexible material, such as paper, itself. A heavier blow, however, may be utilized to cause substantially permanent attachment of the sheets of superposed flexible material, so that they cannot be segregated without actual tearing of the paper material or disintegration of the sheet material. Where the heavier blow for more or less permanent attachment is utilized, any attempt to separate the sheets will immediately show that they have been tampered with, and thus secure against the segregation of sheets or the substitution of one sheet for another. While the invention has been particularly described and is very useful in connection with securing together sheets of paper, any other sheets of flexible material may be treated in the same way, as, for example, Cellophane, light metals, etc., the only requirement being that the material exhibits suflicient strength to enable it to take the seal produced in accordance with the present invention.
It will be seen that because a percussion or impacting die is utilized, such die may be made of any desired size or contour, and when relatively small dies are employed, the area of impaction on the flexible sheets is localized at a particular point, and may be placed at any particular portion of the area of the flexible sheets desired, without requiring that the impacted portion extend from edge to edge of the flexible material.
The flexible material sheets are thus secured together adequately, and either temporarily or permanently, without necessitating the use of complicated devices, and without requiring the use of external binding means, such as adhesives, staples, pins, etc.
While the invention as disclosed herein is illustrated by a structure utilizing an impact or percussion arm and adapted to rest on an article of furniture, the invention may be utilized in a variety of other forms, including devices adapted to be held by hand entirely, or mechanical operation may be utilized to actuate the moving arm or a solenoid may be used for that purpose, any such form coming within the scope of the present invention as long as percussion or impact means is utilized for binding the paper or other flexible material together, without the use of extraneous bindings or binding means.
