This invention relates to pads andholders therefor, and is more particularly related to a padof special construction adapted to be held within a holder `having gripping means to secure the pad in a manner to prevent the pad from being easily removedv from the holder.

In providing pads and holders therefor such, for example, as are adapted foruse in banks, ofices, stores andthe like, the principal problem is to provide a pad and holder thereforwhich will leave all of the surface of the paper of the pad for use, will still lock the pad to the holder to prevent the easy removal of the pad from the holder, and will also permit the individual sheets of paper to be torn from the pad-without tearing the sheets as they are removed. It is essential that the holder be inexpensive in vconstruction and adapted to hold a pad securely to prevent its removal from the holder in any direction until all of the paper of the pad has beenused up. The diiculty encountered in providing such a holder is that the pa-ds of paper are 25 subject to buckling which shortens the distance between the edges of the pad, permitting the pad to fall or be easily removed from the holder. VIn order to provide a holder which will permit the entire surface of the pad to be utilized, it is necessary that the pad of paper be gripped from its sides; If gripping means are provided which extend into the paper of the pad, it is not possible to remove the individual sheets of paper from the pad without tearing the same.

In the provision of a pad for use 1n a holder embodying this invention, it is-essential to the most eiiicient operation that the pad be secured together at the upper edge'of the sheets of paper by means of a glue an-d material which will form a stiH, brittle back from Vwhich the sheets of paper may be easily removed without tearing the same at the upper edge. It is also essential that the pad of paper be mounted upon a relatively stiff back in order to prevent buckling of the individual sheetsof paper to less than'their width and permit the sheets of paper to be withdrawn or fall from the holder. 50 'It is, therefore, an object of this invention vrated gripping surfaces, eachY of which sur- `faces includes a multiplicity of closely Vassoto provide a holder for a pad of ,paper which includes means for gripping the pad at the edges thereof, which means include plates having serrated surfaces providing sharp, short .teeth which extendfrom the surfaces a '55 relatively short-distance and are of a length I insufcient to actually extend into the sheets of paper'of the pad and which provide sharp cutting edges from theirv under-most- Kside which will cut the sheets of paper as they are e0 drawn from the pad to permit the individual sheets of paper to be withdrawn from the pad Without tearing the sheets of paper but extending suiiciently from the faces of the plates to grip the pad to prevent its withdrawal both vertically and horizontally from the holder.

lAnother object of this invention is to provide a holder for pads of paper which includes a back having upwardly extending `70 plates spaced apart a distance equal to the width of the pad of paper to be held thereby, thepplates having a multiplicity of closely associated teeth extending from theirsurfaces a relatively short distance.

Another obj ect of this invention is to provide a pad of paper which may beused for any desired purpose and which is formed of a multiplicity of sheets of paper of equal width secured together bymeans of glue and a binding fabric at their upper end, the gluefbeing of a nature to dryV to form a brittle, stiff back and the sheets of paper being secured by said back to a relatively stiff cardboard. Another object of this invention is to provide a holder adapted to grip pads of paper of different widths and including a back to which spaced gripping plates are Yadjustably secured, the grippingplates providing ser- Iciated, outwardly struck, sharp gripping teeth which are relatively short in length.

Another object of this invention is to provide a holder for a pad of paper including a back having an opening therein into which a portion of thev cardboard back y0f the pad is adapted to lit to hold the pad from being withdrawn longitudinally of the holder.

' Another object of this invention is to pro- 10o vide a pad of paper including a cardboard back divided upon a perforated line to permit part of the back to be torn away and the remainder of the cardboard back to be fitted within an opening formed in the back plate of a holder to hold the pad from being withdrawn longitudinally of the holder.

Another object of this invention is to provide a pad of paper formed of a multiplicity of sheets of paper secured together by means of glue and a fabric at their upper edge, the pads of paper being secured by the glue and securing the fabric to a cardboard back having a perforation therein into which a projection formed to extend upwardly from the back plate of al holder is adapted to fit to prevent longitudinal movement of the pad of paper relative to the holder.

Other objects and advantages of this in vention, it is believed, will be apparent from the following detailed description of a preferred embodiment thereof, as illustrated in the accompanying drawings.

In the holder embodying this invention, l indicates a back adapted to grip and hold a pad 2. The holder has vertically extending plates 3 and 4 preferably stamped out of the back l and a top stop member 5 likewise preferably stamped out of the back l. The

plates 3 and 4 are provided with means for gripping the pad 2 of paper at its edges G and f7 to hold the pad from vertical and longitudina-l movement relative to the hack l and to hold the pad in a manner to permit the entire surface of each sheet of paper to be utilized, and also in a manner to permit the individua-l sheets of paper to be withdrawn from the pad without tearing the sheets of paper and in order to accomplish these objects, the faces of the plates 3 and 4 are provided with rough surfaces preferably consisting of a multiplicity of closely spaced, fine sharp teeth 8 which are formed preferably by pressure of a die producing irregularities confined to the surface of the plate. These teeth have their lower edges 9 sharp so that as the individual sheets of paper are Vwithdrawn from the pad, the cutting edges 9 will cut the edges of the individual sheet but will not tear the same. The teeth 8 are relatively short, being preferably of a length not to exceed lg of an inch. Teeth of this length do not actually project into the edge of the pad but merely act to grip the edges of the individual sheets of paper of the pad to hold th-e pad against vertical and longitudinal movement relative to the back l. The serrated edges of the plates 3 and 4 are formed with the multiplicity of teeth 8 by means of a die or tool which is engaged with the faces of the plates 3 and 4 on an angle so that the teeth are struck upwardly from the faces of the plates 3 and 4 and as the tool or die used is relatively sharp, the teeth as they are struck upwardly are formed with the sharp edges 9. rl"he plates 3 and 4 are spaced apart a distance on the back l so that their faces are a distance away from one another equal to the width of the pad 2. The teeth 8 project inwardly from the plates 3 and 4 to grip the pad.

rl'he pad 2 is preferably constructed of a multiplicity of sheets of paper which are secured to a cardboard back l() by means of a glue and packing fabric secured to the upper edges l1 and l2 of the individual sheets of paper and cardboard l0, respectively. The glue used in securing the gripping fabric and also for securing the individual sheets of paper to the cardboard 10 is preferably what is known as book binders ground bone glue which dries extremely hard or stiff, thereby insuring that the sheets of paper may be withdrawn from the pad 2 without tearing the upper edges of the same. In order to prevent the pad Q'from buckling between the plates 3 and 4 and thereby becoming loose in the holder, the cardboard l0 is preferably formed of a relatively thick cardboard which lwill not easily buckle and this thick cardboard will not be buckled under the slight depression caused by the relatively short teeth 8 formed on the. inner surfaces of the plates 3 and 4.

In the preferred form of this invention illustrated in Figure 4, the holder is provided with means for compensating for pads of different widths, and is preferably constructed of a back la to which guide brackets 14a are secured by means of screws 15a. Plates 3a and 4a are formed of individual pieces of metal bent at substantially right angles and having their horizontally extending portions 16a extending throughV vthe brackets 14a to permit the plates 3a and la to be adjusted inwardly toward each other. I provide suitable means for exerting a clamping force on oneor both of the clamping plates to clamp the pad between them. A plug 17a is screw-threaded in each of the upwardly extending portions. 18a of the brackets 14a. The plugs engagek the outer surfaces of the plates 3a, and 40; to permit the same to be clamped against the edges 6a and 7a of the pad 2a. The serrated gripping surfaces of the plates 3a and la are formed in a manner exactly similar to that heretofore described, the plates 3a and 4a being provided with teeth 8a having sharpened edges 9a. In order to provide an upper stop in this construction of holder, a curved plate 19a is secured to the brackets 1405 by means of the upper screws 15a which pass through eyes 20a formed integral with the curved plate 19a. The curved plate is curved upwardly at its outer edge to provide a holder for a pencil, pen, or the like, as illustrated at The pad 2a used in this holder is preferably similar to the pad 2. The plugs 17a are provided with hexagonal key receiving recesses 22a into which a key 23a having a hexagonal head 24a is inserted in order to clamp the pad 2a in position.

In the modified formof this invention, illustrated in Figure 7, the holder is of substantially the same construct-ion as -illustrated in Figure l so that the same numerals s have been applied thereto, with the addition pad 2b from the holder by drawing the pad 2b from between the holding plates 3?; and 4b.

In the third modified form of this invention, the holder is similar to that illustrated in Figures l and 7 with the exception that intermediate the back 1c a pad 2c Vis interposed an intermediate cardboard 230 through which the plates 3c and 4c and the back stop c extend. Between the plates 30 and lo and back stop 5c, the cardboard 23o is cut away to provide a rectangular slot into which the upper rectangular portion of the cardboard back c of the pad 2c is fitted to hold the pad 2c from being moved longitudinally of the holder. The pad is provided with a complete back 10c which is perforated on a line 240 to permit the lower portion a thereof to be torn away when it is desired to insert the pad in the holder. 'Ihe upper portion 26o of the back 10c then fits within the rectangular slot formed between the members 3c, 40, and 5c and engages the edges of the intermediate cardboard 23e, preventing removal of the pad 2c from the holder. y
