'ro ALL WHOM rr ,MAY concerns;

Be it known that I, JOHN F. SHEARMAN', of Brooklyn, in the county of Kings, and State of New York, have invented certain new and useful improvements in a Pointing Mechanism for Printing Presses; and I do hereby declare that the following is a full and exact description thereof.

lhe object of iny invention is to conveniently provide for operating the points properly in changeable positions on the feed-hoard, or'on the piece let in so as to form apart of the same, without necessitating the turning over oi` the fced-bourd or register-plates, as at present practised. The points are sharp pieces oi' steel or other hard material, which are projected up through the feed-board, and receive the paper thereon, in order to insure the accurate positionl of the paper when thc paper yis subjected to two or moreV successive impressions, and may bc of the ordnarysize, and may project up to thc ordinary extent Two or more are employed on each press, but I will describe the working of only one, it being understood that the other or others are constructed and operated in a similar manner. I will proceed to describe what 'I consider the best means ci' carrying out my invention. The accompanying drawings form a part ofthis specification.

Figure l is a. plan view.

Figure 2 is a central vertical section.

Figures 3, 4, 5, 6, und 'I represent details detached from .the other parts.

Similar letters ofrofcrence indicate like parts in all the gures. Tints are employed merely to aid in distinguishing parts, and do notimply difference of material. The material of the novelm parts may be iron and steel, or other hard, smooth material. i

A is thc feed-board, made of wood, in the ordinary manner; B is a circular frame, letinto the {eed-board, and forming the margin of the circular hole. The point may, by the aid of r'ny invention, be operated with great facility and perfection at any desired point within the area thus bounded. Bl is a flange, which laps upon the food-board, and supports the ring B and the parts depending thereon. B is an internal iiange, at a lower level, which supports the interior work. C is a circular plate of cast iron, or other suitable material, adapted to rest on the flange Bi. It is provided with a slat, c, hevcllcd or dove-tailed as represented, and with clampingpieccs C1 O2, which, by the aid of the screws C3 Oi, and the pins O5 C12-hold the plate C rmly down', by pressing upon both the upper and under faces ot' the flange B2. The plate C may be turned partially or entirely around at any time, after slacking the screws O3 C", and after having been turned in the position desired, it may be firmly clamped in that position by again tightening the screws C3 and Ci by means ofen ordinary screwdriver. D is a rocking-shaft, operated by a mechanism of the press, not represented, through the aid of the arm D. This rocking-shaft is carried in bearings d, secured to the under surface of the feed-board A, and carries an arm, D2, the working end of which is under the centre of the circular plate C. Thepperation of the press raises and lowers the arm'D1 to the proper extent at the proper time to raise and lower the points. E is a bent link, adapted to swivel in the arm D9. Gr is a plate of cast iron, or other suitable material, hung in the hangers g, which are formed on the under face of the circular plate C. This plate G extends parallel to the slot c, before referred to. It receives a rockingmotion from the arm D2, through thc agency of the crooked link E. G1 is an adjustable plate of steel, secureclto the top ofthe rocking-plate Gr by means of the screws G2. The edge of the plate'Gr1 is moved up and down to the same extent as thc point is desired to be operated. This ledge is under the slot c, and the plate G extends the whole length thereon, and is operated to the same extentthrough each portion of its length. I is the point; itis fixed in a smalloircular guide, J, of brass or other suitable material, having a deep groove, j, around it, as represented. The whole'is enclosed in a deep casing, K, which is open on one-iside to allo.7 tlictrayersing on the plate G1 therein. The plate G1 iits loosely inthe groove j,.a.nd at each reciprocatien of the arni D2 and its connections, the point I is raised and lowered to the proper extent. The

casing K is bevcllcd at its upper edge to an extent corresponding with the bevel on the sides of the slot'c. Thel means by whichthe case K is iirmly supported in its position are very clearly shown in the drawings. On the right-hand side in iig. 2 appears a shelf, C7, which extends the whole length of the slot c, and is adapted to firmly support the corresponding side ofthe case Kfm whatever part of thel slot c it may be located. The other side of the case K is supported by the edge of the removable tilting-plate L. This plate is mounted in bearings l, on the under sideoi` the circular plate C, and is confined by movable pins-or screws M, which may be taken Vout to allow the removal of the adjustable plate L altogether, whenever it is necessary to remove the case K and its contents for repairs and the like. In order simply to move the easing and its contents 4from'one part of the slot'c to another, itis not necessa-ryto remove the plate L altogether, but simply to tilt4 it very slightly. This is eiected by slacking the screw N, and when the case K and its ,contents arcvinjthe position desired, the screw N may be` again turned down by a common screw-driver, seas to press on the arm Lt of the tilting-plate L, ns represented, and thus tilt the plate and hold the case K in position very firmly. The cross-bar A1, which may be of wood, may cross under the feed-board in the position represented, and it is necessary simply to provide aeircular clearing-hole in order to allow the crooked link E to turn in all directions, to allow for turning the slot c, so that it shall extendin any desired direction, and the very slight additional mechanism-.described allows the ease K, and consequently the point I, to be changed so as to operate the point in any desired'vposition in the slot c. l

The form of many ot' the parts here described may be modified in variousways.- For example, the clamp piece C1 may be cast in one piece with the plate C. The tightening and releasing ofthe single movable piece C2 will vbe sullieient to confine the plate C in the desired position. So,'also, the blade G need not necessarily be adjustable on the blade It may be welded thereon, or the partsmay be forined together from a single piece ofsteel, or other suitable material, but I prefer the adjustable construction represented, asit promotes the convenience of manufacture, 'and of delicately arranging the relations of the partsl whenever desired. The whole mechanism of' this register, excepting the swivel-link, may be enclosed by the thickness ofthe feed-board, thereby insuring the safety of its light construction in transportation, and rendering it needless to make pro- .vision for non-contact with other parts of the press. i

Some of the advantages due to certain features of my invention may be separately enumerated, as follows: rst, by reasertof the fact that the case K, adapted to receive and guide the point I, with thecasting .I and groove j, is open at its side to allow the edge of the plate G to opei'atet-herein as represei'ite'd,`l am able to operate the point with precision at any desired point in the slot c, without disturbing the relations of the other mechanism, and without requiring any delay in mounting and adjusting the point; second, by reason of the fact that the clamp L, mounted' and arranged asspeciied, will slacken its hold on the case K by simply slackening' the screw N, by working on the upper face of the-plate C, and may again tighten its hold by the reverse operation, I am able to loosen the point and move it into any desired positiomaud to confine it again with great .irmness, and in aananner which, by being directly under the eye of the operator, with thcvfeed-board in its proper position, allows the operation to be effected with more vease and more uiccty than when the feed-board has to be turned over in order to obtain access to the pointing mechanism; third, by reason of the fact that circular 'plate C, and the part-s depending thereupon, may be turned so as to cause the slot c to extend in any desired position by working above the upperface of the feed-board, I am able to adjust the position with more convenience and delicacy than when'thc feed-board has irst't-o be reversed in position. as with the ordinary mechanism.

Having now fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is as follows:

1. I claim the case K, enclosing the point I, and open on one side, to allow the operation of the edge of the blade G1 or its equivalent, so as to operate the point therein in any position in the slot, substantially in the manner and for the purpose herein set forth.

2. I claim, in combination with the above, the clamp L and adjusting means N, or its equivalent, adapted to be conveniently operated from above' the feedboard, so as to set the point in the desired position in the slot c, substantially as herein specified. Y

3. I claim adjustinglthe turning-plate C by operating from the upper side, all substantially in the manner and for the purposes herein set forth. JOHN F. SHEARMAN.
