' Toall whom it ma'y concern:
Be itfknown thatI, SAMUEL E.IBRI GK,:Of Salina, in'the county of Saline and State of Kansas, have invented certain new anduseful Improvements in Books or Pads; and I do 'hereby declare the following to be a full, clear, and exact. description of the invention,
' suclras will enable others skilled inthe art to which. it appertains to make and use the same. v
Myinvention relates to a series of leaves bound together, as books, tablets or pads of paper'or other-material.
An object of my invention is the production'of aseries of leaves suchas a hooker tablet: having a'non friable flexible, elastic or Xieldable non-tacky backing. v nother-object-of my invention isthe pro I duction of a bOOkEOI' tablet having the charvMy invention overcomes these difiiculties' acteristics above set-forth which will retain" such 'characteristics for along period of time.
It, is customary in tableting to pile a stack of leaves or pages upon a base sheet of heavy material and. secure the stack by applying adhesive paste to oneor two edges of the stack;either with or without'a super or extra backing which is usually necessary and which usually extends over part of the base sheet-.1 Owing to the composition of the adhesive heretofore used the tablet is rigid at.
its pasted edge or edges and it cannot be bent v "or folded without breaking. the friable ad-y 'hesive binding; and. an intermediate sheetor sheets cannot be removed without disturbing, the other sheets. Extra sheets, such for example as carbon paper, cannot be inserted without partially destroying the pad.
and furthermore a tablet, pad or bookmade according to. my invention canibe opened I flat or'can be rolledup without damaging the pad. My invention has many other ad- 'vant'a es'which-will be obvious.v
,In t e. drawing, Figure 1 shows a tablet in position for use, and Fig. 2 shows the man,-

This application filed April 26,
' My adhesive binding is a rubber-like mass and is preferably made as follows: 35 parts of smoked plantation or fine Para raw rubber and the same 'amountofunsmoked first latex or best grade unsmoked plantation raw rubber.- a're thoroughly mixed together by passing them throughsuitable high tension I crushing rollers heated to ablood heat,then about 10 parts ofsilica oxids or magnesium v carbonate or fossil flour, 13 parts of calcium carbonate, 6 parts of calcium hydroxid and 1 part of coloring matter are added thoroughly incorporated and mixed with the rubber: This operation requires approximately fifteen minutes. gallons of a. suitable'solvent consisting of about 70 parts of carbon tetrachlorid and 30 parts of benzol .are placed in a mixing drum and into this 100 pounds of the rubber composition I'is 'droppedand thoroughly stirred -About one ounce of deodorant is added foreach gallon ofsolvent, this deodorant consisting of equal parts, 0il of cloves, preferably C. P., andof gum camphor, preferably C. P. The fillers usedshould be very fine and the calcium car 'bonate should beamorphous. The'composition is thenready to be applied. V
The silica .oxids -or magnesium carbonate or fossil .flour'and the calcium carbonate are to a great'extent equivalents of each other in that they give bulk to the composition without detracting from its binding qualities unless used in too great excess. v
I prefer the proportions of the various ingredientsas given above but these may be varied-to a. great extent without departing from-the spirit of my invention and some of the ingredients" may even be, omitted pro vided a composition is obtained-which is flexible, elastic ,'"yieldabl'e and which will not remain. tacky nor become brittlei:
- Anyasuitablesolventfor rubbei may be usedbut I prefer that-indicated. above on account of its non-infiammability and because it leaves the film of applied rubb'er free from :tackiness ina short time.
process-set forth is homogeneous in'thatit is of a uniform nature throughout, having no separate elements,'layers}or structures.
The composition resulting from the I believe I am the first to make 'a' book tor pad with a binder consisting solely ofa j homeogenous composition having-a rubber V The only tableting compounds heretofore known to base .requiring no fabric base;
meare glues .or' rubber compositions which include a cloth or fabric or those in which at an additional cost, their durability is increased. But apart from this feature of r durability the glue binders at no time can produce a tablet having the characteristics of mine, namely, yieldmg, non-friable and elastic. This is the primary feature of my invention. Among the resulting advantages to the'user of the finished product are the following: My tablet may be opened at any point to withdraw a sheet and it will separate easily and its edge which has previonsly been held by the binder will be found clean. Doing this will not disturb any of the adj acent sheets. The same is true when a tab let or book is opened at any desired point to insert a carbon sheet. This is not true of tablets having glue binders. Either the whole ad will break at the point where it is opene or the leaves will not open sufliciently to permit the insertion of the carbon sheet. If the effort be made to remove a leaf from a pad having-a gluebinder the edge of the leaf usually tears and leaves a ragged edge. In warm weather a pad havmg a glue binder presents a sticky surface.
If sheets of it be continuously inserted in a typewriter the particles of glue will adhere to the platen or cylinder and seriously affect the work of the type.
N 0 such disadvantage attaches to the sheets removed from a pad or tablet bound by a compound embod ing my invention.
mm the viewpoint of the user of my compound, that is, the manufacturer of the books, pads ortablets the following advantages are of persuasive force:-My compound is applied cold and with no waste of time. The glue preparations are usually applied hot and time is required for their heat ing; in consequence I save the cost of the heating medium. My compound requires no particular skill in preparation b the user. It is made as herein described eady for his use. The glue preparations are frequently over cooked and have to be thrown away. Any portions of my compound accumulating on the padding table may be redissolved and used again. Glue preparations thus accumulating cannot be used. My compound 'dries in five to seven minutes The glue compound requires from one to ten hours to dry. I can make av tablet with carbon sheets alternating with the leaves and not stain the leaves. Glue dries too slowly for this purpose and while it is drying the moisture penetrates the stock and causes the carbon composition to run and stain the leaves. A tablet made with my compound will not affect the cutting knife while a glue compound will gum and dull it. My compound, when found too thick for the desired use, maybe thinned; a glue compound when thinned too much loses'its strength and it is then a complete loss. If my" compound is thinned too much it may beexposed to the air and it will thicken to the desired consistency. My compound will work in the same way and produce the same results throughout all seasons of the year and under all conditions; glue is affected by the weather and it has been my experience that no two batches work the same. While the foregoing comparisons apply mainly to hot glues, "yet they are also true of cold glues,
with the exception of the time and expense required for heating the hot glues. All cold glues thicken with exposure and cannot be thinned when they become set. They spoil quickly in the can and for this reason cannot be handled in large quantities. Iain enabled to can and ship my compound in any quantity without fear of its deterioration.
rom the foregoing it .will be seen that my process and the resulting compound are of equal advantage to both the manufacturer and the ultimate user of the books, pads or tablets on which' thecompound is used. This application is a continuation of my former application filed. February 1,1919,
