UNITED STATES PATENT JOHN H. MCBRIDE, OF TOPEKA, KANSAS.
SPECIFICATION forming part of Letters Patent No. 593,234, dated November 9, 1897.
Appli i n file February 11, 1897. -Serial No. 622,931. (No model.)
To all whom it may concern.-
Be it known that I, JOHN H. MCBRIDE, a citizen of the United States, residing at T0- peka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Copy Devices, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.
This invention relates to means for furnishing copies for use in schools; and the object thereof is to provide an improved device for this purpose whereby one set of copies may be consecutively used by the pupils in the schools for an indefinite period, a further object being to provide a device of this class with which each of the students may be provided, if desired, to be continuously used by said student; and with these and other objects in view the invention consists in the device hereinafter described and claimed.
Hitherto the teaching of writing from copybooks in which the copies are printed at the top of each page has involved the loss of the copy upon the completion of each page, re-
sulting in great expense for copies or the neglect of the subject of penmanship, and these objections to the method of teaching writing heretofore practiced are overcome by my invention.
The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by the same letters of reference in each of the views, and in whichv Figure 1 is a side view of my improved copy device; Fig. 2, a similar view with part of.
the device in section, and Fig. 3 an end view thereof.
In the practice of my invention I provide a hollow cylindrical casing A, which consists of two similar parts, each of which consists of a half of a cylinder, said halves being designated by thereferencedetter B, as shown in Fig. 3. These separate portions of the cylindrical casing A are provided with tubular bearin gs C at their opposite ends, part of said bearings being formed on each of the parts of the cylindrical casing, and on the upper side of these tubular bearings are lugs or projections E, which extend upwardly a predetermined distance, and I also employ an open ring F, which is adapted to encircle the tubular bearings or the separate parts thereof within said lugs or projections and thereby securely hold the separate parts of the cylindrical casing together.
The upper part of the casing is provided 'with an oblong or longitudinal slot or opening Gr, as shown in Fig. 1, and within said casing I mount a cylinder H, which is provided at one end with an ordinary shaft-J, which is secured thereto in any desired nanner and adapted to enter the corresponding tubular bearing D'or to pass therethrough, and the opposite end of said cylinder is provided with a central longitudinal chamber K and also with a tubular bearing L, which closes the outer end of said chamber, and mounted therein is a shaft M, which is provided at its inner end with ahead m, and that portion of the shaft M which passes through the bearing L is angular in cross-section, and the central bore or opening in said bearing is also angular in cross-section, as shown at m and the outer end of the tubular bearing 0, through which the shaft M passes, is provided I with serrations or teeth, as shown at O, and
the outer end of the shaft M is provided with a milled head which is provided with a "cylindricalliub 0 on which is formed similar serrations or teeth 0 and mounted on the inner end of the shaft M between the head m and the tubular bearing L is a spiral spring P, which is adapted to force said shaft inwardly, so as to cause the serrations or teeth 0 to engage with the serrations or teeth 0.
The under side of the bottom part of the cylindrical casing A is provided with an angular longitudinal projection or shoulder S, and said casing is adapted to rest upon a desk, table, or other support in a stationary position, the longitudinal shoulder or projection S forming a base or support therefor, and when the said casing is placed upon a desk or other support the longitudinal slot or opening G will appear at the frontthereof, as clearly shown in Fig. 1.
On the cylinder H, I secure a sheet of paper having copies thereon, said paper being secured in position by a longitudinal plate U, and the copies on the paper, which is not shown, may be seen through the longitudinal slot or opening G, and in practice both ends of the sheet of paper are placed in the plate U, which is preferably composed of spring metal, and said paper is securely held on the cylinder H, and the said paper may be detached from the cylinder and a new sheet placed thereon whenever desired.
The operation will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statement thereof:
The cylinder H is adjusted by pulling outwardly on the milled head 0 of the shaft M until the serrations or teeth 0 are disconnected from the serrations or teeth 0, when the cylinder H may be turned, as will be readily understood, and when said cylinder is properly adjusted, so that the desired copy will show through the slot or opening G, the milled head 0 is released and the spring P forces the shaft M inwardly and locks the cylinder H in place.
It will be understood that the separate parts of the casing A may be disconnected whenever desired, in order to place a sheet of paper on the cylinder II, by simply turning the rings F until the openings therein register with the lugs or projections E, when said rings may be removed, and said parts of the casing A may be connected by reversing this operation, as will be readily understood.
It will thus be seen that I accomplish the object of my invention by means of a device which is simple-in construction and operation and comparatively inexpensive, and it will be apparent that changes in and modifications of the construction herein described, may be made without departing from the spirit of my invention or sacrificing its advantages.
Having fully described my invention, I
claim as new and desire to secure by Letters Patent- 1. The herein-described copy device, the same consisting of a cylindrical casing, which is composed of two similar longitudinal parts; said casing being provided at one end with a central tubular bearing which projects therefrom, and a cylinder mounted in said casing and revoluble therein, said cylinder being provided at one end with a spring-operated longitudinally-movable shaft, which passes through said tubular bearing, and means connected with said shaft, and said bearing for adjusting the cylinder and looking it in any desired position, substantially as shown and described.
2. The herein-described copy device, the same consisting of a cylindrical casing, which is composed of two similar longitudinal parts, said casing being provided at one end with a central tubular bearing which projects therefrom, and a cylinder mounted in said casing and revoluble therein, said cylinder being providedat one end with a spring-operated longitudinally-movable shaft, which passes through said tubular bearing,and means connected with said shaft and said bearing for adjusting the cylinder and looking it in any desired position, said cylinder being provided with means for securing a sheet of paper thereon, substantially as shown and described.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 261 day of February, 1897. a a
JOHN H. MCBRIDE.
