I 'The present invention relates to new An' object of the inventionis to provide book press apparatus of lgenerally.improved construe-'i tion. y Y

Another object for exerting a substantialpressure. f A further object of the invention is to provide a book press which is relatively simple and durable in construction and eiiicientin use. i l Other objects Aand advantages of the invention` willfbec'ome apparent as the description progresses. I .1 l l. In the accompanying drawings forming ay part of this specification and in which like numerals are employed to designate corresponding parts throughout:

Figure 1 is a top plan view of the improved apparatus,

Figure 2 is a vertical longitudinal section taken on line 2-2 of Figure 1,

Figure 3 is aside elevational view of the press partly broken away to illustrate interior construction, y

Figure 4 is a transverse sectional view as viewed from line 4-4 of Figure 3, l

Figure 5 is an enlarged fragmentary detail section of the lever pivot structure.

Referring in detail to the drawings, wherein for the purpose of illustration is shown a preferred example of the invention, B designates an open top box shaped base member embodying a bottom I0, vertical end walls II and vertical side walls rI2 attached to the end and side edges of the bottom. Within each end portion of the base is mounted a transversely extending reinforcing bar I3 fastened to the bottom.

This base member is adapted to be mounted f horizontally on the top of a supporting table T or other supporting medium.

In each end of the base B is mounted a transversely extending frame element I4, in the present example a length of pipe, securely fastened on the bottom I0 by U-shaped fastening clamps I5. To the ends of the elements I4 are threadand useful improvementsin book press apparatus.

yof rthe invention is the )provi-v sionof a'book presswhich l'is manually operable zoning.: (o1.f1m j-,fs7)fL t v a l t constitutes the bottom frame section ofthe appa`` slidably sited. :upon each-.of the i upstanding posts I 9 is a tubular.l element 20 havingitfs upper end threaded into they depending 'side -outlet of an elbow fitting 2'I. Tofthe'transverselyfprojectingl portions vof. these iji'ttings yare connected the ends of upper transverse elements 22-iwhile to the longitudinally directed outlets thereof Aare (5on5rv lThe eei ments 2l), 2l, 22 and 23 constitutetheuppernov#' nected 'the longitudinal elements: 23.

able section of the frame.

About the lower portion ofeach of the vertieV cal standards is sleeveda coiled-'tension spring A` y 24 having its-l upper endvfastened to the element: by coiling-theend portion about apin"25' thereon and having its lower end attached to a fastening pin 26 secured tothe bottom side outlet elbow I6. These springs function to pull the upper frame section downward so as to yieldingly resist elevation thereof.

On one of the upper transverse members 22 is fitted a sleeve 21 mounted to slide axially thereon and to rotate about this element. About the center vportion of the sleeve v2'I is tightly fitted the straight body portionof a T tting 28 having threadedly connected to its side outlet the inner end of'an operating lever 29 in the form of a rigid bar extending radially from the pivot forming sleeve 21 and provided with a slot 30 adjacent f its outer end. Through this slot is slidably extended a iiat bar 3| having one end pivotally connected to complementary pivot brackets 32 atedly connected side outlet elbow fittings I6 hav- Y ling longitudinally extending portions engaging the ends of longitudinal pipe elements I'I each of lthe sleeve, as best shown at Figure 1.

tached to an end wall `of the base and formed along one longitudinal edge with angular teeth 33 'designed to engage an angular shoulder 34 formed at one end of the slot 30.

',Coiled about the transverse frame element 22 at one end of the frame, at each end of the sleeve 2'I, is a spring 35 having its outer end fixed to the corner fitting 2| and its inner end attached to These springs are designed to exert a torsional effect for yieldingly lifting the handle lever 29 toy an upwardly directed position. l

Through a transverse bore in the intermediate portion of the lever 29 is extended,'perpendicu lar to the lever, the upper threaded portion of a rod 36 carrying nuts 31 for securing the rod in selectively adjusted position on the lever, as shown to advantage at Figure 2. The lower end of the rod 3B is formed with an eye 38 through which is extended a pivotpin 39 attached to the projecting. ends of a pair of complementary angular bracket members 40 fastened to the center books so as to raise the upper skeleton frame sec- Y tion with reference tothe lower skeleton section, particularly with reference to the fixed vertical elements I9 thereof. This places the upper section under the tension of the four corner springs 24 so as to exert the suitable pressure upon f the books. The push rod 36 is adjusted on the lever 29 in accordance with the thickness or num'- ber of books treated at any giventme, the rod,

being shortened when the thickness-is increased and lengtbened downwardly with reference t0 the lever when pressing books of decreased thickness.

'The handle lever isv locked in predetermined downward position. when the upper frame section is raised sufciently tofbring the springs 2.4 under proper tension, by swinging the ratch bar 3|- inwardly so that a notch` thereof I engages the shoulder 34 of theY lever to maintain the pressure on the books for a required period of time. The ratch bar is readily released by slight depression of the lever and outward movement of vthe bar to disengage the shoulder whereupon the movable frame section .is automatically drawn to its downward position and the handle leve!` elevated to an f 1. Ina press of the character described, a base I portion of a board' 4|. As illustrated at Figures upwardly inclined position by the torsional springs 36 in readiness for a subsequent pressing operation.

As will be readily apparent the invention provides a simple and durable press which can be quickly and easily operated to effectively press books and like articles of varying size.

It is to be understood that the form of my invention herewith shown and described is to be takenas a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
