more particularly to an apparatus for form-.
' ing damping rings for-acoustic apparatus,
7 of gu1de rollers from which t passes between and is a division of our Patent No. 1,759,844 of May27, 1930.
The primary object of the present inven- 'tion is to provide a simple and inexpensive apparatus for quickly andeconomically producing articles of sheet material.
In accordance with the, general features of the invention, there is provided in one embodiment thereof, an apparatus for forming damping rings foraco-ustic apparatus in which a ribbon of paperof suitable width is first preliminarily folded in alongitudinal direction and then further folded in order to obtain a predetermined width inthe longitudinal folds produced therein. After the ribbon is folded it is moved between a pair a plurality of spring pressed blades to a pair of pressure rolls which crease the folded paper to form a tape of predetermined width. The damping rings are then stamped from the tape by a die having a larger diameter than the tape thereby leaving an integral connection between the leaves ofthe damping ring. v
It is believed that a complete understandingo f the invention may behadby reference to the following description, taken in conjunction with the accompanying drawings, in which Fig. 1 is a side elevation of the apparatus for forming damping rings embodying the features ofthe invention;

Fig. 9 is a detailed view of adamping ring made by the improved forming apparatus, showing the leaves of the damping ring extended, and 7 Figs. 10 and ils'how aplan-and-endview, respectively, of the damping "ring as it appears W' hen completed by the apparatus with its composite parts in normal position.
Referring to the drawings, an apparatus embodying the invention is shown mounted upon abase 15. At one end of the base a roll of paper 16 is mounted upon an upright spindle 17 upon which it is resiliently held by a pair of springs 18 attached tothe mid- I inthe form of a. ribbon around the guide 21 to a preliminary forming member 22 which is provided with an undulated slot (Fig. 5) whose undulations correspond to the number of folds to be imparted to the paper. From the preliminary forming device 22*the partially folded ribbon which has received its preliminary outline passes between a plurality of dovetailed blades 23 (Fig. 4) which are alternately supported on opposite sides of the ribbon. Each of the blades 23 is mounted in a tapering bar and the bars are supported upon standards 24 and 25 in such a manner that the blades converge in the direction of travel of *the ribbon so thatthe ribbon enters the blades as it is formed by the preliminary forming device and leaves the blades in the form of a composite tape of six leaves. The bars supporting the outside blades are carried by bolts which are movable in slots upon loosening of the thumb screws 26 to permit a separating of the blades for the purpose of threading the ribbon of paper through the blades when a new roll Oi paper is inserted {in the apparatus.
It is quite impoI-tant-thatthe leaves of the folded paper should have a predetermined width so as to leave a connection of uniform length between the leaves when a damping ring is later stamped therefrom. The width of the leaves is determined by the amount of overlapping or dovetailing of the blades 23. In order to adjust the amount of overlapping of the blades, the standard 24 is mounted upon a slidable member 31, a portion of which engages a T-shaped slot in the base. A clamping member 32 occupies the T-portion of the slot and serves to clamp the member 31 in place upon the operati n f a cam which exerts an upward force upona bolt 34 to which the clamping member 32 is attached.
The folded ribbon passes from the blades 23 through a pair of guide rolls 35 to a plurality of parallel blades 36 which are alternately supported on opposite sides of the ribbon. On the one side, the blades are carried by a support 37 and on the other side by an arm 38 which pivots about the point (Fig. 3). The arm 2:38 also carries a pair of compression members 41 (Fig. '7} which engage the blades 36 at the point where they contact with the folded ribbon and exert a pressure thereon. A spring 42 (Fig. engages the arm 38 and serves to hold it in operative position. In oreer to thread the paper tape through the blades 36 the arm 38 may be swung about its pivot 39 to render the blades more. accessible. The folded paper passes from the blades 36 between creasing rolls 43 and 44 and thence to a punch press 45 in which the damping rings 46 are stamped from the tape. 4
The roll 43 is mounted upon a shaft 49 and mounted upon the same shaft is a toothed wheel 40 (Fig. 8) which is engaged by a plu rality of pawls 47. The pawls 47 are mounted in a cup-shaped opening of a wheel 48 which is loosely mounted upon the shaft 4-9. A link 51 connects the wheel 48 to a. bell crank lever 52 which is actuated by an ad justable link attached to a plunger 27 of the punch press 45, a movable punch and a stationary die carried by the plunger and the frame of the press being indicated at 28 and 29, respectively. The bell crank lever is provided with a slot 54 in which a slidablc member 55 is adjustably mounted for the purpose of varying the amount of movement of the link 51 and the travel of the tape. When the plunger 27 of the punch press 45 descends, the pawls 47 will slide over the toothed wheel 40, and when the plunger ascends, the pawls will engage the teeth on the wheel 40 to rotate the roll 43 an amount sufficient to advance an unstamped portion of the tape under the plunger of the press. A handle 50 is also provided by which the rolls may be rotated manually in threading a ribbon into the apparatus.
The rolls 43 and 44 are interconnected by gears 56 and 57, causing the rolls to have the same peripheral speed. The lower roll is mounted upon an arm 58 which is pivoted at 59, permitting the roll to be dropped for the purpose of threading the paper tape through the rolls. The lower roll is maintained in pressing engagement with the upper roll and the paper tape by means of a spring pressed plunger 61 and may be disengaged therefrom by moving a cam shaped lever 62 to; its vertical position.
In the operation of the apparatus, the paper ribbon passes over the guide 21 to the preliminary forming apparatus 22 where the ribbon is longitudinally formed into a plurality of undulations. The paper ribbon is then passed to the overlapping converging blades where folds of a predetermined width are imparted to the paper and from which the paper emerges in the form of an accordion pleated tape of a predetermined width passing through guide rollers 35 and between the spring pressed blades 86 into the rolls 43 and 44 where the edges of the tape are firmly pressed together to form a crease. The paper is then intermittently advanced to the punch press 45 by the mechanism described above. The diameter of the punch 28 is made slightly larger than the width of the folded leaves so that when a clamping device 46 is stamped from the paper tape a narrow hinge 61 will remain on opposite sides of the damping device connecting the various leaves as shown in Fig. 9. It will be seen therefore that it is very important that the paper tape be folded in such a manner that the leaves are always of a uniform width in order that the hinge or connection between the leaves shall have a uniform length. Figs. 9, 10 and 11 show a damping device in which the leaves are interconnected by hinges or connections 61 which form cords of the annular periphery of the damping device.
It will be understood that the embodiment of the invention herein described and illustrated is merely a convenient and useful form of the invention which is capable of many other modifications without departing from the spirit and scope of the invention.
