BENJAMIN J. PAVYER AND THOMAS BURNS, OF ST. LOUIS, MISSOURI, ASSIGNORS TO JAMES G. PAVYER, OF SAME PLACE.
PAPER-CUTTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 479,302, dated July 19, 1892.
Application filed February 29 1892.
To all whom it may concern.-
Be it known that we, BENJAMIN J. PAVYER and THOMAS BURNS, both of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Paper-Outtin g Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
Our improvement relates to an improvement in the clamp by which the paper is held while being cut; and it consists in making the clamp in two parts, as and for the purpose hereinafter described, and as set forth in the claims.
Figure I is a transverse vertical section taken at I I, Fig. IV, showing the operative parts in front elevation. Fig. II is a transverse vertical section taken at II II, Fig. IV, showing the operating parts in rear elevation. Fig. 111 is a rear view of the main member and the hinged member of the clamp detached; and Figs. IV and V are detail longitudinal sections taken at IV V, Fig. II, showing the hinged member of the clamp in its ineffective and in its effective position, respectively. Figs. VI and VII are enlarged detail sections taken at VI VII, Fig. II, showing the hinged member of the clamp in its lower and upper position, respectively. Fig. VIII is an enlarged detail horizontal section taken at VIII VIII, Fig. II.
1 is the table of the machine.
2 are standards at the sides of the machine giving bearing to the knife or cutter 3 and other parts, for which no novelty is here claimed.
4. is a cross-bar in which turns a vertical hand-screw 5.
6 is a hand-wheel on the screw.
The hub 7 of the wheel and the collar 8 bear against the top and bottom of the cross bar, respectively, and prevent the vertical movement of the screw in the bar 4.
9 is the principal member of the clamp-bar, which has guide-ribs 10 at its edges working in vertical guide-grooves of the standards.
11 is a nutinserted in a recess 12 of the clamp-bar 9. The screw 5 works in the nut 11, passing through orifices in the clamp-bar Serial No. 423.273. (N0 model.)
9 above and below the nut, as shown in Figs. II, IV, and V. It will be seen that as the screw 5 is turned the clamp-bar has vertical movement. The part 13 of the clamp-bar that bears upon the paper has little thickness, so that the gage 14 (see Fig. V) may be brought quite near to the knife, thus allowing the use of the gage when only a narrow strip has to be cut off the pile of paper. It will be understood that it is preferred that the width of the bearing-edge of the clamp should be sufficient to prevent creasing or disord ering the paper, and as the clamp is interposed between the gage and the knife the cutter cannot be used when the strips of paper to be cut off are narrower than the clamp. Hence the advantage of having the clamp adjustable in width. Our improvement gives a very ready means for making this adj ustment.
9 are lugs upon the rear side of the clampplate 9, in which are fixed the ends of a pintle-pin 15, on which the movable member 16 of the clamp turns up and down.
17 are hinge-lugs on the clamp member 16, through which the fixed pintles 15 pass. 18 are set-screws screw-threaded in the pintles 15 for securing the hinged member in its upper or lower position, the screws being loosened to enable its movement and then screwed in tight to hold it in position. The hinge-lugs 17 are slotted circumferentially at 19 to give place for the shanks of the setscrews as the movable clamp plate or member 16 is thrown up or down from the position shown in Fig. IV to that shown in Fig. V, or vice versa. The body of the plate has orifices 20 for the passage of the heads of the set-screws as the plate 16 is swung on its hinges. The set-screws 18 act alike to hold the member or plate 16 in its lower or upper position. The plate 16 has a broad base 16, one edge of which extends below the lower edge of the member 9 when the plate 16 is in the working position shown in Fig. IV.
The construction of the machine is such that when the movable part 16 of the clamp is thrown up into its inactive position, as seen in Fig. V, the ascent of the clamp is limited by the impingement of the edge 16 against the stops 2, while the ascent of the clamp when the part 16 is down is limited by the impingement of the top of the part 9 against the collar 8. In each case the lower working edge of the clamp is below the edge of the knife when the clamp and knife are both in their upper positions, so that thereis no danger of the operator being cut by the knife.
We claim as our invention- 1. The combination, with the paper-clamp member 9, of the hinged member 16, adapted to be raised and lowered on the paper-clamp member, substantially as described.
2. In a paper-cutting machine, a paper clamp consisting of a member 9, sliding in fixed ways, and a member 16, hinged to the member 9 and having a broad base 16, adapted to extend below the lower edge of the member 9, substantially as set forth.
3. The combination, in a paper-cutting machine, of the clamp having a sliding member 9 and a member 16, having slots 19 and orifices 20 and hinged to fixed pins 15 of the member 9, carrying setscrews 18, all constructed and adapted to operate substantially as set forth.
4. The combination, in a paper-cutting machine, of the clamp having a sliding member 9 and a member 16, hinged to the member 9, so as to be raised and lowered, the knife 3, and the gage 14, the clamp being constructed and adapted to operate substantially as set forth.
