MIGUEL PIEDRA, or WILLIAMSBURG, NEW Y K.
IMPROVEMENT IN PAPER-FEEDING MACHINES.
Specification forming part of Letters Patent No. 136,668, dated March 11, i873.
To all whom it may concern: Be it known that I, MIGUEL Williamsburg, in the county of Kings, State of New York, have invented anew and Tmproved Machine for Feeding Paper, of which the following is a specification:
presses or other apparatus in which such paper is to be prepared for further use, in suitable manner; and the invention consists principally in the application to this purpose of an air-pump, which is moved back and forth over the paper, and which, when it arrives over the pile or heap of sheets from which it is to feed, causes suction to be applied to the upper sheet, so that the same will adhere to a'pendent pipe from such pump, andwill bemoved with said pump in its forward motion,
and then discharged from the pipe aforesaid by the suddencontraction .of the pump and closing of the suction-pipe to which the sheet adhered, and expulsion of air from the same.
The invention furthermore consists in novel appliances for moving said pump or air cylinder, for opening and closing-that is to say, for 1 expanding and contracting it during its motion for opening and closing the valve in the pen ent pipe, to which the paper. adheres; for
raising the paper to and against the end of said pipe; for holding the pump extended while moving toward the heap of paper and for other purposes necessarily connected with the operation of this apparatus.
In the accompanying drawing, Figure 1 rep- .resents a side elevation of my improved palperrfeeding machine. Fig. 2 is a vertical central section of the same on the line 0 0, Fig. 3. Fig. 3. is a plan or top-view of the same. Fig. 4 is a front elevation, and Fig. 5 is a detail vertical transverse section on the line K K, Fig. 3. y
Similar letters ofreference indicate correspending parts. i l V V A in the drawing represents a framework of metal or other material, of suflicient size and proper shape to sustain and hold in position all the parts, hereinafter named, of my improved machine. B is a shaft, hung in the frame. A in a transverse position, and applied to one endof thelframe,which I willdenomi- .anate-the front 'end of the same. To this shaft Prnnnh, of
B is, by gear-connection or otherwise, im parted rotary motion from a driving-shaft, O, that hangs in the frame A, or is otherwise supported. A wrist-pin, a, of the shaft B connects by a rod, with an oscillating frame,
. E. that is, at I), connected with the backpor- This invention relates to a new machine for feeding paper in successive sheets to printing tion of the frame A. The frame E consists of two uprights, as indicated in Fig. 3, said uprights being, at their upper ends, connected by a rock-shaft, d. -To this rock-shaft is con nected a yoke, F, which extends forward of the rock-shaft, and at its front end carries a" cylinder, G, which is rigidly connected with another rock-shaft, e, that hangs in uprights f, whose lower ends are at j pivoted to the frame A, as shown in Fig. 1.
It will be observed that the uprights f and the uprights of the frame E are parallel with each other, and that, being by the cylinder G and yoke F connected with the upper part of said frame E, they only constitute part and parcel of the same frame, and move in con; junction therewith when the same is oscil- V lated by the shaft B, serving thus to carry the cylinder backward and forward during the oscilla-tions. From the cylinder Gr projects downward a tube or pipe, g, whose lower end is or may be slightlyenlarged or made cup-shaped inversely, and which is provided with a valve, h, which valve can be turned, as in Fig. 2, to open said pipe, on'at angle thereto to shut the same. H is a plunger entering the open front 7 end of the cylinder G, and connected by a cross-head, i, with two horizontal bars, ll, that slide or fit into the parallel sides of the yoke F. Springs m m of rubber or metal connect the cross-heads of the plunger with the yoke, for the purpose of drawing the plunger into the cylinder G whenever said plunger is not by other means kept or drawn out of the same, more or less. In lugs or ears n that project forward from the uprights f is hung a crankshaft, I, from which cranks o 0 proj ect upward, while another crank, p, from the same shaft 1, is, by a rod, q, connected with the lower back part of the frame A, in manner clearly shown in Figsil and 2.
It may here be well to observe that Fig. 2 ,is represented as looking inthe opposite direction to Fig. 1, so that the rod q and all the parts arranged on the'same side of the machine can be plearly seen in both figures.
in the ends of the rods Z.
Whenever, during the rotation of the shaft B, the frame F with its branches is moved backward, its connection with the rod q will tend to gradually carry the same more and more toward an upright position, which motion will cause the rock-shaft I to be swung so that its arms "0 'will be more and more moved forward against shoulders or projections 1" that areformed on the cross-head'of; the plunger H.- Therefore, as these arms 0 bear against the projections r, the plunger, will be moved forward and drawn out of the cylinder G until it finally reaches the position shown in Fig. 2; and it will, when thus drawn out, create avacuuni in the cylinder. In this position the plunger H is looked, as soon as the cylinder G has reached its most backward position, by sprin g-pins s s, which enter notches The spring-pins 8, being applied to the yoke F, as indicated in Fig. 5, crowd, by their spring-connection, up-
"on the rods l constantly, so that they will readily lock into the notches of the same when the same arrive under such pins. Being thus locked in open position the plunger H is held so drawn out of the cylinder G, while subsequently the said cylinder G is moved forward and until the same has reached its most forward position; thenthat is to say, when the most forward position of Ghas been obtainedthe arms 0 of the crank-shaft I bear backward against spring-slides t that hang at the sides of the yoke F, and push said spring-slides backward on the yoke so as to carry wedges a that are secured to the back ends of the slides 2? under the pins 8, or under pins that connect with the springs that bear on s, raising the same out of the notches of the rods 1 and releasing the plunger. The springs in thereupon immediately and forcibly draw the plunger into the cylinder and into the position shown in Fig. 1.
By means hereinafter more clearly set out, the valve hin the tube gis opened when and as soon as the cylinder Greachesits most backward position, and shut as soon as the same cylinder reaches its mostforward position. This makes it clear that during the gradual drawing out of the plunger while the cylinder moves back no air supply is admitted to the cylinder, and that when the plunger is pushed into the cylinder, the valve It being closed at the same time, no air-escape from said cylinder is permitted.
To avoid the friction which would necessaril y follow such great contraction and expansion of air, and the large amount of power involved therewith, I have made the back end of the cylinder G open, and have placed an elastic diaphragm, V, over said opening, as shown in- Fig. 2. The diaphragm will be bulged or drawn inwardly when the'plunger is being drawn out, and will be forced outward when' the plunger is forced into the cylinden'thnsii accommodating itself to the greater 'or less; rarefaction of the air contained in the same. 1
The paper to be fed-by this'apparatus is in the form of superposed sheets placed upon a table, J, at the back part of {the machine. This table is made ,up-and-down adjustable, either by being hinged at its back end or secured upon a vertical slide, w, and is especially made up-and-down adjustable at its forward end. Springs a: are applied to its under side to draw its'forward end'down upon a fixed support of the frame A. L is a rock-shaft,
hung in the frame A slightly below the front part of the table J. This rock-shaft is connected with a powerful spring, 3 which tends to spring or hold it in such position that a small crank, a projecting from'it will be elevated and carried against a downward projection, I), of the table so as to elevate said table. At one end of said rock-shaft L isfound a projecting crank, 61 When the cylinder G is-being moved forward by the means aforementioned, a pin, e, on the rod q, moves over the crank 61 and carries it down into the horizontal position shown in Fig. 1, and thereby swings the aforementioned projection a down and extends the spring 3 the shaft 'L being in this position locked by havingits connection with the spring y brought in line with its own axis and with the pin attachment of said spring, as shown in Fig. 1. When the cylinder G is moved back a projecting foot, f '4, on a spring-slide, 9 that fits on one of the rods f, arrives under the crank (1 and just at the time that the cylinder G reaches its most backward position a crank, h, of the shaft I, raises the slide g by arriving under an ear thereof, and raises also the aforementioned foot f and swings the crank d up. This will return its power to the spring 3 and will cause the same to violently and quickly swing the shaft L back into the position shown in Fig. 2, and thereby quickly throw up or elevate the table J. This elevation of the table J is obtained by the projection to falling against the pro jection b of the table. Anothercrank, '6 on the shaft L will at the same time be'thrown against the lower part of a slide, M, that han gs in the frame A, directly forward'of the table J, and will throw said slide violently upward against a crank, 3' of the valve h, and will thereby open said valve. Thus, it will appear, by taking observation of all that has already been described, that at the time that'the cylinder arrives/at its backward position, in.
which positionits pendentpipe g will arrive over the pile oflpapers resting on the table J, the plunger H is drawn out of the cylinder, a vacuum, or at least a rarefaction of air created therein, and that at the same, time the papery-is, by the elevation of the table J, r"ais'ed into contact withthe cup-shaped lower end of the pipe g, and the valve h. simultaneously opened. Therefore the vacuum in the cylinder will be applied against the upper sheet on the table, and will suck the same against the lower end of -the pipe g. The cylinder at this time .m akes its forward motion, and takes theupper sheet forward with it until after it has reached its most' forward position. The plunger is, by ;the means before described, violently thrown P is, of course, simultaneous with the enteiy in g of the plunger into the cylinder, and consequently the valve is shut at the same time that the plunger enters the cylinder; the paper being therefore discharged from the end of the tube g by the shutting of the valve as much as orrather more than by the expulsion of air from the cylinder. The cylinder now resumes itsbackward motion, and the operation aforementioned is repeated until the paper on the table J has been entirely removed, in successive sheets.
In place of one tube, 9, a series of such tubes may be extended from the cylinder to act upon the same sheet, or upon a series of sheets on several layers, in substantially the same manner.
The mechanism herein described is not intricate, and is easily kept in repair; and the means of feeding the paper is certainly the most advantageous that can be devised, because it dispenses with all the griping devices by which the sheets are more or less injured.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The cylinder G, provided with pipe 9, plunger H, and valve h, combined with the table J, all arranged to operate substantially as and for the purpose described.
2. The combination, with plunger H and notched rods Z, of the spring-pins s 8, arranged as and for the purpose set forth.
3. The spring m, arranged in combination with the yoke F, and spring-pins s s, and slides t, for forcing the plunger into the cylinder as soon as the latter has reached its forward position, as set forth.
4. The crank-shaft L, provided with pro jections a i and (1 in combination with the table J and-slide m, to-raise the two latter simultaneously, as set forth.
5. The oscillating frame E and uprights f, arranged in conjunction with the yoke F, cylinder G, rock-shaft c, and connecting rod D, to operate substantially as described.
6. The combination, with slide 9 arranged in upright f and provided with a bearing-foot,
f of the shaft I, and crank 11 and shaft L, in the manner described. 7. The combination of the lever N, the plunger H, the lever P, and the valve h, to move the latter at the end of the forward motion of the cylinder G, as set forth.
