Applioatiomfiled September 5, 1912. Serial No. 718,631.
To all whom it may concern:
Be it known that 1, WILLIAM A. Oven- BECK, a citizen of the United States, and a resident of Salt Lake City, in the county of Salt Lake and State of Utah, have invented a new and Improved Book-Marker, of which the following is a full, clear, and exact description.
This invention relates to book markers and has reference more particularly to the class comprising a member adapted to clamp a page.
An object of the invention is to provide an inexpensive and simple book marker that will have a firm grip on the paper and W111 not injure or mar the page in places of contact with it.
Another object of the invention is to provide a book marker that will equally well hold one or a few pages of a book or of paper in file and indicate their place.
Reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views and in which Figure 1 is a plan view of an embodiment of my invention; Fig. 2 is a section on line 2-2 of Fig. 1; Fig. 3 is a side view of same in operation; and Fig. 4 is a plan view of the two parts forming the device.
Before proceeding to a more detailed description of my device, it must be understood that while the drawing discloses the invention formed of two fiat resilient members riveted together, the same may be punched out from a single piece and then properly folded, the upper portion pressed together and thereby obtaining the same effect as with the rivets.
The marker can be made of any metal suited for the purpose, and the upper partof the device may be numbered, lettered or otherwise marked as means for identification.
The device may be oxidized,,enameled or otherwise covered so as not to be injured by the atmospheric conditions and mark the paper when in contact.
Referring to the drawings, 10 is a page magnified in thickness and it is clamped by the lower part or jaws of members 11 and 12 one on each side of the page, the clamping action of the jaws bein due to the resiliency of the material ad ed by the rivets 13 binding the members 11 and 12, and by the curved portions 14 and 15 formed preferably ,mldway between the extremities of these members 11 and 12, said curved portions forming springs for the jaws engaging the ObJGCt. The bent portions 14 and 15 are increased in resiliency by providing an orifioe 16 in the member 11 and the curved portions 14, and by cutting out similar notches 17 at each side of the member 12 also in the curved portion 15. This reduction in material gives more resiliency to the members 11 and 12 and also permits the curved portion 15 to project through the orifice 16, while the curved portions 14 will register with notches 17 as best shown in Figs. 2 and 3. The curved portions 14 and 15 of the members 11 and 12 are preferably elliptical in curvature so that when the members are bound together by means of rivets 13, the curved portions will afford a large sur face and, therefore, an easy grip for fingers of the hand, the upper part of the device being provided with the numeral for distinguishing from similar markers when used together. When the marker is to be placed in a desired position, the fingers are applied to the curved parts 14 and 15 of members 11 and 12, and forcing the fingers toward each other, the lower part of members 11 and 12 or the jaws are spaced so as to admit the page or pages desired.
As can be seen from Fig. 2, the lower part of the members 11 and 12 are closer together at their extremity so as to make the contact surface between the jaws and the paper increase until the two jaws are parallel that will clamp the paper by bearing against it with their entire surface and thus insure a good and even grip on the same.
It must also be remarked that my book marker can also be used as a paper fastener simultaneously as a marker for loose papers inclosed in a file of other papers.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
1. A device of the class described comprising a pair of members in juxtaposition, each of said members having intermediate its ends a bulged portion, said members havin openings in said bulged portions where y said portions extend past each other, each of said members, wit-h the exception of its bulged portion being wholly at one side of the other of said members and means binding said members at one end and therer by forming the fulcrum for the opposite ends which are adapted to engage the page of a book, said ends normally converging toward each other from the bulged portion of the members.
2. A device of the class described comprising a pair of resilient members, one of said members having a central "aperture intermediate its ends and the other of said memhers having notches intermediate its ends at the sides thereof, the said members having a bulged portion formed where said aperture and said notches respectively are provided in said members, said members having the same sides opposite each other through the entire length with the exception of said bulged portions, and said bulged portion of one of said members passing through the aperture of the other of said members, and the bulged portion of the othersaid member passing through the notches of said first member; means at one end of said members bindin them together and forming a fulcrum %or said members, and the opposite ends of said members diverging from the extremities toward the bulging portions.
In testimony whereof I have signed my.
name to this specification in the presence of i two subscribing witnesses.
