Application filed May 7, 1915. Serial No. 26,542.
To all whom it may concern:
Be it known that we, CHARLES Homasrnn Nnw'roN, THEODORE DANETEISER, and FREDER- ICK FRANCIS Fromm, citizens'of the United States, and residents, respectively, of Plainville, Conn, borough of Manhattan, city and State of New York, and borough of Brooklyn, city and State ofNew York, have invented certain new and useful Improvements in Duplicators, of which the following is a specification.
The invention relates to duplicators, and more particularly to the type of such machines provided with a duplicating surface adapted to receive negative or reversed impressions and rolling means for pressing a sheet of paper or the like thereupon.
The invention has for one of its princi-' machine in which pal objects to provide a the paper 1n conthe operation of placin tact with the surface, ta ng the impression, and removing the paper, may be performed efiiciently, quickly and easily.
The invention consists in the novel construction, arrangement and combination of various devices, elements and parts as shown in the accompanying drawings, after more particularly described.
In the said drawings, Figure 1 is an end view of my invention; Fig. 2 is a section of one end of my invention, taken on the line 2-2 of Fig. 1; and Fi 3 is a detail view to be hereinafter descri e I In carrying our invention into efiect in the embodiment thereof which we have selected for illustration in the accompanying drawings and description in this specification we provide a base member 71. Secured to this base member is a frame member 72, the shape of which may readily be comprehended by an inspection of the drawings. This frame 72, and parts secured thereto, may be extended as far as desirable to the left of Fig. 2, the left hand end being supported upon the base 71 in a manner analogous to that in which the right hand end is supported. The frame 72 comprises the side portions each having two pedestals and a connecting portion, anda horizontal bedportion 73 preferably integral with the side portions and connecting them throughout the greater portion of their length. (See particularly Fig. 2). The bed 73 forms the immediate support for the portion of the and hereinto bear against duplicating medium which is in use. The bed may be covered with a strip of canvas or the like 74. (see Fig. 2) which extends over its upper surface and around both ends, the extremities being joined together under the bed 73, and the strip held taut, by means of any suitable means (not shown). I
The duplicating medium used is in the form of a strip or roll 75. The portion in use is stretched over the canvas 74 on the bed 7 3, while the end portions after assing Over rollers 77 adapted to prevent riction of the same against the ends of the bed 73, are wound upon the rollers 76, of any suitable construction (only one of which is shown). Suitable means for removing or replacing either of these rollers, or rotating them, or holding them against rotation, are also provided.
Mounted between the sides of the frame 72 is a rod 80. This rod is free to rotate, but is held against longitudinal movement by washers 81. Rigidly mounted on this rod is a member 82, having a portion shaped as shown at 83 in Fig. 2 to receive the end of a sheet of paper.
Loosely mounted on the rod 80 is a member 84: provided with a surface 85 adapted the end of the paper at 83 and clamp the same. This member 84 is provided with a perforation through which passes a pin 86 extending from the member 82 and bearing at its outer end a washer 87 between which and the member 84: is a helical spring 88 adapted to hold the member 8& in close contact with the member 82. The member 84 is also provided with an upward projection 89, adapted to be engaged by the impression roller, as will be hereinafter described.
' downward against the duplicating surface by means of springs 100 mounted in the side portions 93 of the movable carriage, (see particularly Fig. 3) the distance to which the roller may be forced downward being adjustably regulated by means of the upward thrust of the screws 101. When the movable carriage is in the position shown in Fig. 2, the projection 89 is engaged, the clamping member 8 1 forced backward, and the apparatus in position for receiving a sheet of paper, 102. Mounted on the frame 72 are two strips 103, each provided with a slight de pression 110 (see Fig. 2) in which the roller 95 is adapted to rest when in the position sliown'in Fig. 2. The carriage is thus held in position against the tension of the spring 88, although a slight leftward pull upon the handle 94 is sufficient to release it.
The operation of a duplicator embodying our invention is as follows:
The canvas 74; is adjusted upon the bed 73, and stretched tightly thereon. The end of a strip of duplicating material 75 is suitably secured to one of therollers 76, wound thereupon, and the other end secured to the other roller 76; and the rollers 76 may then be placed in position in the frame 72, the member 82 and attaching devices being temporarily lowered out of the way.
The strip of duplicating medium passes over the bed 73 and rollers 77. The portion thereof of-which it is desired to make imvmediate use is brought into position by manipulation of the rollers 76, and the duplieating medium then drawn taut. A negative or reversed impression of the matter which it is desired to copy, may then be transferred to said duplicating medium in the usual manner.
A. sheet of paper 102 on which it is desired to make acopy is placed in position. This paper is slid down over the guide 96, (the sliding members 97 being adjusted as desired) between the rollers 98 and 99 and against the stop 83. The movable carriage in this position should occupy the position shown in Fig. 2, in which position, it will be observed, it is beyond the end of the bed 7 3, and the roller 95 bears against the finger 89 and holds the part 85 out of engagement here shown and designated The paper being placed in this position, i
the movable frame is then slid toward the left by means of the handle 9%. The first result is to release the finger 89 and allow the portion 85 to descend upon the stop 83, securely clamping, the paper.
As the movement is continued, more and more paper is drawn over the guide 96 and roller 98-, and into contact with the duplicating medium, until nearly every part sue .cessively receives the pressure of the roller 95, this movement being continued until the movable frame strikes such a stop as is provided, and which is tion that the paper tirely through the movable frame, the end of the paper being held by the operators hand. The frame is then moved back to the right, the roller 95 passes again over that part of the paper which is in contact with the duplicating medium, and more and more paper is successively stripped from the duplicating medium and slid out of the movable frame between the rollers 98 and 99 and over the guide 96. When the movable framev reaches its extreme right position, the finger placed in such a posi 89 is forced backward and the attached parts operated, whereby the end of the paper is released, and the finished copy may be withdrawn. A new sheet of paper is then placed in position, and the operation repeated. In this manner as many copies as desired may be taken, and the rollers 76 may then be operated so as to bring into position a fresh portion of the duplicating strip adapted to. receive a new negative impression.
The advantages of our invention will be obvious from what has been said above con cerning its construction and mode of operation, but some of them may be enumerated as follows: Owing to the elimination of unnecessary parts the apparatus is simple and inexpensive, while still efficient in operation; rollers do not come in contact with each other at any time; the duplicating medium may be easily and quickly unwound and rewound, and new rolls of the same substitutedwhen necessary.
Having thus described our invention what we claim as new and desire to secure by Letters Patent is as follows:
1. In a duplicator, the combination with a frame having a bed, and a duplicating film thereon; ofa carriage slidably mounted on said frame, a clamp loose on a shaft, journaled in said frame adjacent one end of said bed, means adapted to depress said clamp upon a sheet of paper orthe like, means adapted to release said clamp com prising a finger rigidly attached to and extending above said clamp, and a roller journaled in said carriage adapted to move over may not be drawn enit is capable of rapid operation; the
teaser? said bed and depress a sheet of paper or the'like on to said duplicating film, and to pass beyond the end of said bed, thereby leaving a space between an end of said bed and said roller into which may be inserted the end of a sheet of paper or the like, said roller being also adapted to engage with they finger on said clamp.
2. In a duplicator, the combination with a frame having a bed, and a duplicating film thereon; of a carriage slidably mounted on said frame, a shaft mounted in said frame, devices mounted on said shaft adapted to receive the end of a sheet of paper or the like, and means adapted when in one position to maintain said devices in operative position, and when in another position to allow said devices to be moved out of operative position. v
