NrrED STATES PATENT FFCE- JOHN H. DARLINGTON, OE NEW vonk, N. Y.
IMPROVEMENT IN PAPER-FEEDING APPARATUS. y
Specification forming part of Letters Patent No. lll-6,1322, dated January 13, 1874; application filed Y June 10, 1873.
To all whom it may concern.: v
Be it known that I, JOHN H. DARLINGTON, of the city, county, and State of New York, have invented an Automatic Feeding Apparatus for Paper Blanks, Sac., of which the following is a specification:
`My automatic feeding apparatus is cony structed to feed all sorts of paper and other lar blanks is shown in position. Fig. 4 is a front elevation of the machine, the blanks and the endless bands ff being removed. Fig. 5 is a transverse section of the plate b, with one of the uprights, l', attached thereto..
a a are two vertical sides of a frame, which support a horizontal plate, b. There are three rollers, c d e, which carry two or more endless bands, ff, the rollers being placed so as to lead the endless bands over and in close contact with the top of the plate b. gis an endless apron, running Aover a pair of rollers, h i, and
'provided with paddles at equal distances from each other, intended to receive the blanks, one by one, in the spaces between the paddles. k is a` pile of blanks, placed upon the plate b, be-
"tween two upright angular guides, l l', which "are fastened upon the plate b. The rear sides of these' angles do not reach down to the plate b, butleave an open space, marked m in Figs.
@and 5, through which the lowest blank can *slide when the two endless bands f f are pnt jnmotion in the direction of the arrow shown Fig. 1, and, by means of their friction against the lowest blank of the pile, carry the said blank backward and drop it upon the carrying-apron g. To prevent more than one blank being carried out at once, the upright guides Z l are furnished at their rear sides each with a strip of elastic india-rubber, n, or
y other pliable material, which reaches down to l the plate b, and exerts a slight pressure upon the blanks as they are being carried through the open space m.. The revolving motion of the bands j' f is obtained by connecting the roller e with the roller h by a driving-belt running on pulleys c and h.
To insure the regularity of the feeding of the blanks, the following mechanism is employed: A rookshaft, o, carries two arms, o' o', which are each provided with a vertical pin, p, at the front end, which is looselyitted, and is capable of sliding in its bearings, being brought down by its own weight. A small collar, x,
attached to the pin, determinesthe amount of play of the pin up and down in its bearings. When these two pins are down, resting with their lower` ends upon the plate b, they prevent any blanks from passing out. At one end of the rock-shaft there is an arm, q, attached thereto, which bears upon a cam, r, ofthe center shaft of the roller h, and is lifted by said cam once in every revolution of tlieroller h, thus lifting the pins p from the plate b, and permitting a blank to pass out. The carryingapron g and the roller h are so arranged and geared as to receive one blank'n every revolution of the roller h. The cam r must be so timed as to lift the'arm q, and hence the pin p,
at such a time as to enable the blank to reach the apron g at the proper place and time, and must be so shaped as to drop the pins p immediately after a blank has passed out, to stop the next blank until its time has arrived. y In all cases the motion of the pins p mustbe regulated by the main shaft of the machine to which the feeding apparatus is to be adapted. If attached to a press, the pins p must be operated by the eccentric-shaft of the said press. The endless bands f f, in order to increase their friction against the blank, and insure their capability of Acarrying the said blank, may be sanded or otherwise made with a rough surface.
The abovedescribed plan of ,construction may be modilied in various ways. Instead of employing the endless bands f j' below the pile of the blanks to pull out the lowest ofthe blanks, the said blanks may be made `to operate on the top of the `pile and remove them permost blank, in which case the pile of blanks should be lifted up by a counter-weight or spring, to bear against the lower side of the endless bands; or else the bands may be dis.
detaining-strips n 11., Wliereby the feeding of the single blank is accomplished.
3. The combination of feeding-aprons ff, reciprocating stops p p, and delivery-apron g, substantially as described.
J. H. DARLINGTON.
