PAPER-PERFORATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 4'? 1,923, dated March 29, 1892.

Application iiled September 15, 1890. Serial No. 365,045. (No model.)

To all whom it may conceive:

Be it known that I, VILLIAM F. WELLS, a citizen of the United States, residing at Oleburne, in the county of Johnson and State of Texas, have invented a new and useful Paper- Perforator, of which the following is a specitication.

This invention is acombined gripper-bar and perforator for use on printing-presses.

In the drawings in which I have illustrated Inyinvention, and in which like letters of reference indicate corresponding parts in all the views, Figure l is a plan view of my device. Fig. 2 is a perspective view in detail of one of the perforator-bars. Fig. 3 is a similar view of a part of another form of perforator-bar. Fig. 4 is a view showing in part a variation in the structure of my device. Fig. 5 is a side elevation of one of my perforator-bars. Fig. 6 is a transverse sectional view of the perforator-bar E. Fig. 7 is a sectional view taken at the point of junction of the bars D and E and Fig. Sis a transverse sectional view of the bar A, showing the bar B fastened thereto.

In the drawings, A designates the side bars, which have their edges ct beveled, and are provided with bolt-holes d for attachment to the rod X, to which the ordinary grippers are usually attached.

B is a perforator-bar, having near each end the dovetailed grooves h for the purpose of engaging the side bars A.

b indicates small screws passing through the ends of the perforator-barB and binding against the beveled edges of the bars A for the purpose of fastening the perforator-bar at any desired position along the length of the bars A.

The bar B has along its inner side a series of holes b2 and a shoulder b3, both for a purpose to be hereinafter described. Along the length of this bar at its top are perforatingneedles b4. Below the perforating-needles is a recess b5, extending along the bar, leaving between it and the needles a shelf b, slightly below the level of the upper surface of the bar, where the needles are placed.

57 are leaf-springs, each attached to the bar B at one end and having its body extending in a curved line upward above the surface of the bar, where its free end is broadened, as

shown at hs, so as to adapt it to rest upon the shelf bf when depressed.

The above perforator-bar B may be used in connection withvthe side bars A alone when it is desired merely to make one line of perforations in a sheet of paper, and in doing so the leaf-springs 197 will, when the needles are pressed against the paper, be pressed backward upon the shelf h6, allowing the needles b4 to puncture the paper, when upon the receding of the type from the paper the springs will be released and press the paper away from and off the needles; but when-more than one line of perforations is desired' the same may be obtained by using duplicates of the bar B for lines parallel thereto and of the same length, or by using the following parts when the lines desired are at right angles to the line made by the perforator-barB or parallelthereto and shorter, or when they form an acute angle with any of the other lines.

O is a bar designed for the purpose of connecting the ends of the side bars A to render them more rigid and also to afford, in conjunction with the bar B, a support for the additional perforating-bars. The bar O has along its inner side a series of holes c, corresponding in position and number with the holes b2 in the bar B, and it is also provided with a shoulder c.

D is a perforating-bar, similar in general structure to the perforating-bar B, differing only from it in a few minor parts which adapt it to connect and be held by the bars B and O. For instance, its ends are out away on the under side, as shown clearly at CZ, to form shoulders which may rest in the shoulders b3 and c.

d are lugs or pins projecting from the ends of the bar D, and adapted to enter the holes b2 and c in the bars B and O and be retained therein.

The perforating-bar D is provided with a hole or with a series of holes d2 upon its inner side, and also has a shoulder d3 for the purpose of receiving and fastening the end of an auxiliary perforating-bar E.

The perforating-bar E may be of the same construction as the other perforating-bars B and D; but I have preferred to show a oonstruction somewhat different from the latter,

IOO

and for some reasons a construction much more desirable.

The perforating-bar E is designed, primarily, for perforatin g a line shorter than that perforated by the bar B and parallel thereto, and with this object in view it is formed with a dovetailed groove e, adapted to receive one of the side bars A, which groove is near one end, and also provided with a shoulder e and a lug or pin e2 on the other extremity, which is adapted to engage the side of the perforating-bar D. A small screw e3 passes through the outer end of the bar to the dovetailed groove e, and is designed to press against one of the beveled edges ct of the side bar A.

The perforator-bar E is provided with perforating teeth or cutters e, arranged in the present instance in sets e5 of three teeth separated by a space. The depth of the spaces e, between the sets of teeth e5, is greater than that of the spaces e7 between the teeth themselves, and extends below the upper surface ot' the bar E.

e9 is a depression extending the length of the bar, in which depression are springs ew, which support a flexible strip en, which is provided with tongues el, adapted to pass through the spaces e6 between the sets of teeth. The object of this construction is the more eiectually to relieve the teeth, cutters, or needles of the perforating-bar from the paper as the saine recedes from the gripper by the tongues @12 rising between the sets of teeth at short intervals instead of bythe sides of the teeth.

It will be evident that the arrangement of teeth in sets of three is merely shown for convenience, as I may without departing from the spirit of my invention have the tongues project through all the spaces between the teeth, instead of between every third space, or I may put the tongues farther apart.

In using my invention I tirst attach the side bars A to the rod X in the manner indicated and then adjust the perforating-bar B at the proper place upon the said side bar in relation to the paper which is to be perforated. It' it is desired to perforate more than one line in the paper, the bars C, D, and E are added as may be needful, or in their places or the places of some of them may be substituted blank bars of their general form and construetion, such C. It is to be remembered that these bars are all rigid and serve as gripers. p While I have described the device as adapted to perforate paper in lines parallel to each other and at right angles to one another, itis evident that by a slight change in anyone of the dovetailed grooves or of the attaching devices lines may be perforated at any angle desired. I have shown such a change in Fig. 5, there being no departure from my invention in the change there shown and no addition thereto, but merely an expedient to attain a well-known object-namely, to perforate paper in lines at an acute angle with each other.

I have described with some particularity the means of attaching the perforating-bars to the side bars and to each other; but I do not desire to limit myself to any such specific construction, as I may employ any convenient mode of connecting the parts.

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

l. In a device for perforating paper, the combination, with the side arms of the grip per, of the perforating-bars longitudinally adjustable thereon, substantially as and for the purpose described.

2. The combination, with a rigid perforating-bar, of a releaser arranged longitudinally along one side of the bar and a series of springs located at diierent points beneath the releaser-bar and connected to the perforatingbar and holding said releaser normally above the plane of the perforating-teeth, the said releaser being provided with aseries of tongues that are adapted to project between the teeth of the perforating-bar, substantially asspecified.

3. The combination, in a device for perforating paper, of the rigid side arms with the perforating-bars, the said arms and bars being provided with means for attachment'one to the other and being adj nstable in relation to each other, substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I have hereto aiXed my signature in presence of two witnesses.

WILLIAM F. WELLS.
