PAD HQLDER Filed Aug. 9. 1930 Patented May 26, 1931 UNITED s'rrrs PATENT oFF-ice JOHN IB.KE1VIP, OF RIDGEWOOD, NEVI JERSEY, ASSG-NOR TO CLARK LOOSE LEAF MAN FACTUR-ING COMPANY, A CORPORATION OF NEVI YORK` PAD HOLDER Application filed August 8, 1930. Serial No. 474,121.v

This -invention relates generally to pad holders adapted to retain a calendar ring or other memoranda in position, and more particularly to an arrangement for holding a group o'f'superposed members in proper relationand in angular position with reference to the supporting surface.

AThe present invention is an improvement over my copending application, Seria-l No. 426,547, tiled September 7, 1980, and provides in addition to all of the objects provided in the aforementioned application, the provision of improved securing means for the. pad holding and aligning bolts.

t is thus among the objects of the invention to provide improved means for receiving and securing pad holding bolts in conjunction'with the pad supporting surface.

Another object is to provide bolt receiving means associated with the base for threadedly receiving the vbolt therethrough without threading the base or otherwise directly imparting strains from the bolt thereto.

Another object isto provide'a bolt securing attachment for a pad holding base in which the bolt engagement is independent of leg supports and whereby the legs may be moved independently and without respect to the location of the bolts.

Other objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel arrangement and co-relation of inst-rumentalities herein fully described, and illustrated in the accompany* ing drawings, wherein similar reference characters are lused to describe corresponding parts throughout the several views,and then finally pointed out and specifically defined and indicated in the appended claims.

The disclosure made the basis of exemplifying the present inventive concept suggests a practical embodiment thereof; but the invention is not to be restricted to the exact'details of this disclosure, and the latter, therefore, is to be understood from an illustrative, rather than a restrictive, standpoint.

The inventive idea involved is capable of receiving a variety of mechanical expressions,

only a few of which, for the'purposes of illustration, are shown in the accompanying drawings, in which- Fig. 1 is a view partially in section of one form of the present invention in position on a disc, and taken on theline 1 1 of Fig. 2.

Fig. 2 is an end elevation of the device shown in Fig. 1.

Fig. 3 is a detailed section'taken o'nlline 3 3 of Fig. 2.

Fig. 4 is a view similar to Fig. 3 showing the supporting leg in folded position.

Fig. 5 is a detailed view of the bolt engaging element. v

Fig. 6 is a view similarto Fig. 3 offa modified form of the inventionand Fig. 7 is a detailed view ofthe modified bolt receiving element. In the drawings, l represents a pad which, for the purpose of illustration, isfa calendar pad, the pad resting ona base 2 and being apertured as at 8 to receivecombining screws 4 therethrough. In previous forms ofthe present invention they combining screws were adapted for threaded engagement into heads 5 of standards or legs, which are pivotally carried bythe underside ofthebase ,by reception ofthe heads within sockets 7 carried by the base. While the generalr structure of the previous devices is herein illustrated as a preferred embodiment, the structure involving the use-of caps 8 and spring 9 which are adapted to retain the standards in their adjusted position, one'side` of the socket being open to permit their -foldingas indicated -in Fig. 4, the invention departs fromy the Lprior teaching by the provision of a screw orrbolt receiving plate 10 which in thefform of the invention shown in Fig. 3 is mounted on the upper surface of thebase 2an'd secured over the aperture 11 of the base by the socket securing rivets 12.

The element 10 as shown in Fig.v 5 is elongated, its ends being apertured as at 13, to receive the rivets 12 therethroughV and its center being apertured and internally threaded to provide aboss 14 for threadedly engaging'the lovverend of the screw 4. Asa manufacturing expedient, theelement l10 isherein shown ashaving its central portion'eXt-'ruded and internally threaded, it being understood however, that the linvention is not confined to this mechanical expedient.

The head 5 of the leg or standard 6 is not internally threaded as in accordance with prior practice and is apertured with a bore greater than the diameter of the screw. The screw when the pad lis full does not extend into the standard head 5 and permits the standard to be freely moved-but properly secures the pad by engagement in the boss 14 of the element 10. Thus the device may be shipped with the legs folded and the pad firmly secured upon the base. After considerable thickness of the sheets of the pad is removed, downward screwing of the bolting provides for the entrance of its lower end within the head 5 to prevent accidental fold.- ing of the standard.-

By this form of the invention lit will be seen that the pad is secured independently of the standard and strains are directed notdirectly to the base which may preferably be formed of paper material, but are carried through the i element 10 to be distributed through the rivets 12, thus eliminating danger of disrupting the threaded connection.

By referring more particularly to that form of the invention shown in Figs. 6 and 7, it will be seen that the invention comprehends the use of securing screws 4 out of alignment with the standard 6. In this instance the screw receiving element, as shown in Fig. 7, is indicated by the numeral 20 and has apertures 21 adapted to receive the socket securing rivets 12. The element 20, however, extends beyond one of the apertures 12 and has an extruded end boss 22 which is adapted to be received within an aperture 23 of the boss 2, and thus provides for the alignment of the screw 4: out of the axial path of the standard 6. In the use of the device, regardless of how thin the pad becomes through removal of sheets, the screw 8 will never extend downwardly to interfere with the folding of the standard.

In both forms of the invention, it will be seen that a novel and simple structure is provided, by which a rigid screw receiving boss is provided, so arranged as to prevent 'mutilation of the boss by engagement of the screw therewith, and also arranged to be secured independently 0f the standard. These features provide for free folding of the standard without regard to the position of the screw and provide an inexpensive structure particularly designed to meet the demands of economic manufacture.

In accordancewiththeprovisions ofthe patent statute, I have described the principle of my invention, a practical embodiment thereof, but I desire it understood that my invention is not confined to the particular form of device herein shown and described, the same being merely illustrative, and that the invencomplished, as herein set forth, as it is obvious that the 4particular embodiments herein shown and described are Vonly some of many that can be employed to Vattain these objects and accomplish these results.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
