YORK, A CORPORATION OF NEW YORK;
Specification of Letters Patent.
Patented June 11, 1907.
Application filed October 25,1905. Serial No. 284,292.
To (all whom it inn/y concern.-
Be it known that I, FREDERICK G. J AHN, a citizen of the United States, residing at the borough of Brooklyn, city of New York,
county of Kings, and State of New York,
have invented certain new and useful Improvements in Feeding Mechanism, of which the following is a specification.
The present invention relates generally to lo feeding mechanism adapted to feed single pieces of paper'or other material or mail matter and the like in succession from a pile, stack or bunch thereof.
It has for its object to provide a simple I 5 and inexpensive mechanism adapted without adjustment to efiiciently operate on uniform and non-uniform matter or material with equal facility; and furthermore to improve the general construction of the mechanism, and to render certain of its parts subject to wear easy of substitution.
As a better understanding of the improvements will be had from a detailed descri tion of a practical embodiment thereof such description will now be given in connection with the accompanying drawings, in which:
Figure 1, is a plan view of the improved mechanism associated with a portion of a printing mechanism of well known type. Fig. 2, is a sectional side elevation of a portion of the feeding mechanism. Fig. 3, is a sectional end elevation thereof, Fig. 4, is a horizontal section on the line 4 of Fig. 2. Fig. 5, is a erspcctive view of the wiper, removed from its place. Figs. 6 and 7 are vertical sections on the lines 6 and 7 respectively of Fig. 2.
The improved feed mechanism A, is shown associated with a printing couple B, and accompanying parts as usually arranged in a well known type of post ollice mail matter marking nuu-hinc, and of the character illustrated in my United States Letters Patent, No. 657,939, dated September 18, 1900, simply by way of illustrating an embodiment of the invention to practical purposes.
The printing couple consists of the usual die or rinting roller and impression roller 16 wilii which is associated a pair of feed rollsis 123, 14 and a trip iingcr 205 for controlling the rotation of the printing roller in a manner similar to that set for h in my said Lettors Patent.
The feed mechanism A consists of a feed 55 roller 12 carrying a rubber feed surface 12 with which may be associated a supplemental and smaller feed roller 11, also having a rubber feeding surface 11*. Opposed to the feed roller 12 is the improved wiper-separator by which the feed of single pieces is insured. This consists of a flexible wiper and a bearer 30 arranged one in advance of the other to bear against the feeding surface of the feed roller in the manner indicated in Fig. 1.
The bearer and wiper are carried by a supporting guide or plate 3 secured through an intermediate block 6 to a post 5 which rises through a hole in the machine base C from one end of an arm 4, that is hung on a pivot 2 carried in said machine base; the construction adapting the bearer and wiper to move or yield bodily away from the feed roller against the tension of a suitable spring 18, to accommodate the feed of different thickness of: matter through the machine.
The supporting guide or plate 3 extends, in the main, parallel with and along one side of the pathof movement of the pieces passing from the feed mechanism to the printing couple, the opposite side of said path being guarded. by a fixed guide 28. At the entrance to the feed mechanism the guide or plate 3 is bent outwardly to provide a flared entrance for the material passing between the wiper and feed roller. This bent portion of the supporting plate forms an angularly arranged or inclined seat for the wiper 50 so that the tendency of the wiper is to occupy the position shown in Fig. 4, but which, owing to its flexibility, will, in bearing against the feed roller, have its free end bent inwardly toward the supporting plate as in Fig. 1.
The wiper 50 is preferably a rectangular piece of rubber of suitable thickness and backed with canvas or other material 55, to prevent it from stretching, with a central hole 10, adapting it to engage a iixed stud 1, projecting from the angular or inclined seat provided by the supporting plate 3, see Fig. 4. Between the angular seat of the guide or plate 3 and the back of the. rubber is interposed a distance piece 7 whose particular function is to form a space in rear of the forward free end of the wiper, Figs. 1 and 7, so that when the latter is in use its end may yield slightly with respect to the supporting guide or plate. The distance 'piece 7 is formed with flanges 8 to engage the opposite maybe easily remover 'the surface of the wiper interposing sulli-- and 6, form a pocket to receive and protect 13' be sufiiciently lasting, the wiper may be backed up by a slender spring or springs 17,
sure against the feed roller 12 and. 11, but
rotation of the feed rollers carries the piece onward into the bight between the roller 12 2 asses? edges of the wiper to keep it in proper alinel ment, and its outer inactive end is guarded l and partially overlaid by the bent end of a plate 9' which may extend outwardly at rig t angles to the direction of feed of the material to form a guide therefor to the flared entrance for said material. The flanges 8 and bent end of the plate 9, Figs. t
the outer end of the wiper 50. As the flexibility of the substance of the wiper may not Figs. 4, 6, and 7, the outer ends of the springs being guarded by a shoulder on the bearer 30.
In the preferred construction the wiper 50 has its hole 10 .centrally arranged therein so that, after its one end has become worn, it may be removed from its stud 1 and changed end for end and replaced with its worn end extending intothe pocket behind the end of the late 9.
.The spring 18 may be any suitable form. As shown, one of its legs is supported by a short stud 20 in the machine table and the other engages the supporting post 5, and
In operation, a bunch or stack of the mat' ter to be fed through the machine is arranged vertically on edge withthe forward ends directed toward and entered slightly into the flared end of the feed mechanism with the outermost piece bearing with a gentle presmainly exerted against the roller 12. The
and the wiper 50, past the wiper, thence between said roller and the bearer 30, to the feed rollers 13, 14 and forward into the printing couple. ()wing to the position and arrangement of the wiper 50, only one piece at a time will be permitted to be fed forward,
cient friction to the forward ends of the succeeding pieces to prevent their forward movement while the first piece is being fed by the roller 12. As soon as the tail of the first piece of matter has passed beyond the forward end of the wiper the next succeeding piece will be forwarded by the feed roller 12. The desired space between succeeding pieces of matter may be governed by the relative nieii therefrom in the improved construeu arrangement shown and herein o ainmd.
What is claimed is: 1. The combination with feed device, of a yieldingly mounted guide pr clined seat and a bearing block, ble wiper supported on said 'wi end and the bearing biock arra pings against a moving o. device.
2. The combination. with a feed a yiehilinqly mou: ted guide in bearing. block and aninciined stud, and. a flexible wiper supper" seat and mounfed i said stud end and the bearing block arra. pinge against moving surface 0.2. device. i
3. The combination with a yieidingiy mounted gun-o clined and pocket or gua ing block, a fiexibie wiper r seat and extendiu; free end and he bean impinge against moviny device. 4. ihe combine-ti" i a yieiding'iy mou bearing pinch. and stud, and a wiper arranged hole adapting seat and stud with the iree and the bearing bit-ch. against a moving surface of 5. The combination witl'i a guide providing an inciined with its free end ranged to impinge ainst a niovi. of the feed device, and a spring the guide and reinforcing the 1. i wiper.
