UNITED STATES FREDERICK A. CELLARIUS, OF SAN FRANCISCO, CALIFORNIA.

DEVICE FOR OLAJHPING AND HOLDING PAPERS, ETC.

Application filed April 16, 1923.

To all whom it may concern.

Be it known that I, FREDERICK A. CELLA- IuUs, a citizen of the United States, residing at 601 Clement St, San'Francisco, in

the county of San Francisco and State of California, have invented. new and useful Improvements in Devices for Clamping and Holding Papers, Etc, of which the following is a. specification.

This invention relates to improvements in devices for clamping and holding papers, pads and the like and resides in the provision of a simple, inexpensive and highly efficient device of this nature which may be easily operated to clamp a pad or sheets of paper and to hold the same in such position that the paper may be writtenupon in a con venient manner.

An object of the invention is to provide a novel device of this nature especially as to the clamping means and the arrangement for operating the same upon depressing the paper supporting plate, which latter is disposed at an inclined position, to facilitate 25 writing on the paper.

Another object is to provide a device of the character described which will be small, compact and capable of convenient use upon a desk or table.

A further object is to provide a device of the character described which is conttructed so that papers and the like may be very quickly and easily clamped and held in position for reference thereto or to be written upon.

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, and set forth in the claims hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Referring to the drawing:

Fig. 1 represents a vertical sectional view of the device of my invention as it would appear when holding a pad in place.

Fig. 2 is a top plan view of the device.

Fig. 3 is a rear elevation thereof.

Referring to the drawing, the embodiment base plate 1 and a supporting plate 2 of sub of the invention shown therein includes a- Serial No. 632,569.

stantially the same size and of rectilinear outline. The plate 1 is adapted to rest upon a table, deslgor like support and at one end has a suitable hinged connection 3 with the corresponding end of the plate 2. An expansion spring 4 is interposed between and secured to the plates in such manner that the supporting plate 2 will normally be supported in an upwardly and outwardly inclined position but may be depressed to operate the clamp as will be later more fully described.

The clamp comprises an arouate jaw 5 hinged as at 6 to the upper end of the plate 2 and arranged so that it extends upwardly and forwardly from the hinge and then downwardly. It may be operated to clamp between it and the plate 2, a pad A or loose sheets of paper, which latter are not shown.

The plate 2 is provided with an inwardly extending recess 7 at its upper end through which recess a downwardly directed tongue 8 extends. The tongue 8 is struck downwardly, from and formed integral with the jaw 5 and at its lower end is formed into an eye 9. Pivoted in the eye 9 is the bight portion 10 of an inverted U-shaped link 11,

the free ends of which link are bent right angularly as at 12 and are rotatable in bearing members 13 which are formed integral with the plate 1. It will thus be seen that the link 11 limits the upward movement of the plate 2 and with the spring normally provides for holding the same in the inclined position shown in the drawing.

The free edge of the jaw normally engages the upper side of the plate 2 and when it is desired to clamp and support a sheaf of papers, or a pad, the paper or pad is placed on the plate 2 so as to extend slightly onto the jaw 5, and the plate is depressed while thus supporting the papers or pad. Upon depressing the plate 2 against the action of the spring 4, the link 11 will act with the tongue 8.150 swing the jaw 5 upward and rearward. When the jaw has been swung upwardly away from the plate 2, the paper or pad falls on the plate so that it will extend beneath the jaw and upon quickly releasing the plate, the spring will force said plate upwardly and cause the jaw 5 to move into position to clamp the papers or pad, for example, as shown in Fig. 1.

It will thus be seen that the device not only serves as a means for effectively clamping and holding papers and the like but provides for a convenient writing on the papers or pad thus held. a An advantage is that but a simple movement is required in order to clamp the papers or pad in place, it only being necessary to depress theupper plate with the paper thereof as described, whereby the jaw will clampthepaper or pad. The comparatively large rectangular base plate will provide an adequate stand or support for the plate 2. The link, jaw and tongue arrangement is such'as to insure a positive and full c-peningmovement of the jaw upon a slight depression of the plate 2 and to prevent said parts from sticking or jamming on dead center. 7

I claim:

1. A device for clamping and holding papers, pads and the like comprising a base plate, a supporting plate hinged to the base plate, a spring interposed between said plates and tending to move the. supporting plate upwardly, a jaw pivoted on and extending above the supporting plate between which jaw and the platepapers or pad are to beclamped, a projection on said jaw and an upstanding link pivoted to the base plate nd projection at its ends. 2. A device for clamping and holding pa pers, pads and the like comprising a base plate, a supporting plate hinged to the base plate, a spring interposed between said plates and tending tomo-ve the supporting plate. upwardly, a jaw pivoted on and extending above the supporting plate between which and the plate papers or pad are to bef'clamped, a projection on said jaw,

said supporting plate having an. opening therein through which the projection extends, a link pivoted at its ends to the base plate and said projection, said jaw being curved and extending upwardly and forwardly from its pivot connection and then forwardly and downwardly to a point over an intermediate portion of the supporting plate.

3. A device for clamping and holding papers, pads and the like comprising a base plate, asupporting plate hinged to the base plate, a spring interposed between said plates and tending to move the supporting plate upwardly, a jaw pivoted on and ex tending above the supporting plate lJQtWOCll which jaw and the plate papers or a pad are to be clamped, a link extending upwardly from the base plate and a projection on the jaw and pivoted to said link. said supporting plate having an opening therein through which the projection extends, said projection at its point of connection with the link being disposed below the pivot connection of the j aw.

4. A device for clamping and holding papers and the like comprising a base plate, a supporting plate disposed above and movable relatively to the base plate, a spring interposed between and tending to move the supporting plate upwardly, a jaw pivoted on the supporting plate between which jaw and said supporting plate papers or the like are adapted to be clamped, a link pivoted to the base plate at one end and means of pivotal connection between the other end of the link and said jaw.
