Title: Improvements in or relating to book-leaf holders and bookmarkers
IPC: B42D9/00
Filed: 1932-06-24
Abstract: 400,348. Bookmarkers ; index tabs. INGAMELLS, A. B., 64, Montague Road, Clarendon Park, Leicester. June 24, 1932, No. 17891. [Class 16.] A leaf-holder for book, adapted to be used also as a bookmarker, consists of a strip of material, such as celluloid, metal, cardboard, or stiff paper, provided with one or more tongues, teeth, or the like formed on the strip by cutting or punching the material and bending the portion or portions thus formed so as to enable them to be inserted between the leaves at the top or bottom of an open book, to hold the strip or a portion thereof in position across the open book so as to extend wholly or partly over the opposite pages of the book to prevent turning of the leaves thereof ; when used as a bookmarker one or more tongues &c. are so disposed to enable the strip to extend lengthwise between the pages of the book. In the form shown in Fig. 1, the strip 1 has parallel sides and shaped ends, and is provided with two transverse V-shaped tongues 3 and a similar tongue 2 disposed longitudinally near one end. For use as a leaf-holder it is applied to a book so that the tongues 3 clip over the top edges of one or more leaves on opposite sides of the centre of the open book, the main portion of the strip bearing on the fronts of the exposed pages; when used as a bookmarker the strip is disposed at right-angles to the top of the book and the tongue 2 clipped over the top edge or edges of one or more leaves. In a modification the device consists of a long narrow limb disposed longitudinally of the book, which widens near the top wherein only two tongues are disposed for engagement with the top edges of the opposite pages of the book when used as a leaf-holder, and for use as a bookmarker the strip is disengaged, moved laterally of the book, and clipped over one or more leaves on one side of the open book. In the form shown in Fig. 6, the device is provided with a single tongue 2b obliquely disposed, and the strip is triangular in shape. The full lines show the device used as a leaf-holder, and the dotted lines show its use as a bookmarker. In this case the device may be brought into bookmarking position by a simple lateral movement from leaf-holding position. In each form described each tongue consists of an integral V-shaped portion produced by cutting or punching, and at 9, where it is united with the strip, it is bent away from the strip, then bent in the opposite direction at 10, and then at its point 11 is bent away from the strip at an angle. The tongues &c. may, however, be constituted by integral shaped parts on the edge of the strip bent over to the back thereof. One or more of the devices may be used in books or the like for index, reference, or similar purposes, in which case the exposed end or ends may bear indicia.

Abstract: 787,860. Mine props. STEINKOPF, W. June 24, 1955 [June 25, 1954, Oct. 25, 1954, May 4, 1955], No. 18403/55. Class 20(2) In a telescopic pit prop an upper and inner prop member 2, Fig. 1a, has on its lower end an inverted cone 3 which cooperates with the upper part of a double cone annular wedge assembly 4 frictionally engageable on its outer face with the lower and outer prop member 1, the lower part of the wedge assembly 4 being engaged by an upright cone 5 mounted on a rod 6 which is connected to the prop member 2 in an axially adjustable manner, the cone 3 having a smaller taper and greater length than the cone 5. In one embodiment the rod 6 carries a prop head 12, Fig. la, and is connected to the prop member by means of a wedge carrier 7 transversely slidable in apertures in the upper prop member and having an inclined slot 9 which receives a protrusion 10 on the rod 6. A spring 5a is interposed between the cone 5 and a flange 6a at the bottom of the rod 6. An initial movement to the right of the wedge carrier 7 lifts the rod 6 and wedge 5 and expands the wedge assembly 4 into a frictional grip with the prop member 1 sufficient to retain the prop at a predetermined length. Further driving in of the wedge assembly 4 to the right Lifts the rod 6 against the pressure of the spring 5a, forces the head 12 against the mine roof, and applies a reaction to the prop member 1 which acts upon the cone 3 and wedge assembly 4 to generate the necessary braking force of the wedge assembly 4, which increases with an increasing load up to a maximum beyond which the prop yields. Withdrawal of the prop is effected by driving the wedge carrier 7 to the left to lower the rod and cone 5 and release the wedge assembly 4. The head 12 also lowers with the rod 6, thus ensuring that the prop can be removed under load when, due to the small taper of the cone 3, the lowering of the cone 5 does not release the wedge assembly 4. In a modification Fig. 1b, the rod 6 is urged upwardly to lock the prop when clutch pieces 23 are forced on to opposite sides of a cone 22 at the upper end off the rod 6 by means of readily releasable wedge actuated clamping means 24, 25. The wedge assembly 4 consists of a number of separate segmental pieces such as 14, 15, Fig. 2, separated by intervening spaces 13 arranged so as not to extend along a continuous line parallel to the prop axis. The individual pieces of the wedge assembly 4 may be connected by a resilient plastic element 4a, Fig. 2.
