BOOK-COVER RUBBING AND CLEANING MACHINE.

assess.

Application filed September 3, 1910.

To all whom it may concern:

Be it known that we, ANTHONY L. Dnnx LER and WILLIAM H. DITTMAR, both citizens of the United States of America, and residents of Jersey City, in the county of Hudson and State of New Jersey, have jointly invented a new and useful Book-Cover Rubbing and Cleaning Machine, of which the following is a specification.

This invention relates to a novel machine for rubbing and cleaning book covers particularly devised for the purpose of removing the excess of gold leaf, silver leaf, aluminum leaf and metal leaf in general from the back and sides of the book cover when same are ornamented by print and embellishing designs.

Heretofore when the title of the book, the authors' name or the like was applied to the back of the book cover or when the sides were embellished by beautiful designs, the letters and designs were first usually produced thereon by printing them without any color or gold leaf for instance, so that there were merely impressions in the cover. Then the gold leaf was applied largely in excess and that excess was generally removed by hand. This was a rather tedious, painstaking and time taking operation involving considerable expense.

The present invention has for its purpose to produce a book cover rubbing and cleaning machine which removes the excess of gold leaf quickly and effectively without injuring or defacing the desired golden print or ornamental designs. For this purpose we have constructed a machine comprising an automatic feeding device, a reciprocal movement with soft rubber attachment at the bottom of same or a suitable brush so constructed that the soft rubber or brush passes over the book cover and removes the excessive gold leaf. Means are provided for shifting the book cover into the machine and means for securing the latter in a fixed position. There are further means to deliver the cleaned book covers into a suitable box or basket, and means to recover the excessive metal leaf, all as will be fully described hereinafter with reference to the accompanying drawings in which:

Figure 1 represents in top plan View a book cover rubbing and cleaning machine embodying in desirable form the present Specification of Letters Patent.

improvements. Fig. 2 is a side elevation of same. Fig. 3 is a longitudinal vertical section through the machine. Fig. 4 illustrates the machine in front View, and Fig. 5 is a vertical sectional detail view of the driving mechanism shown in Fig. 3.

Similar characters of reference denote like parts in all the figures.

In the drawings a represents substantial frame work with a supporting plate Z) extending laterally. The plate I) is centrally cut out as shown in Figs. 1, 2 and 3 for purposes to be mentioned later on. Two guide plates 0 are adjustably mounted on the plate Z) one each near its side end portions. Below these guide plates there are slots 5 in the plate 5 to allow of adjusting said guide plates sidewise so as to conveniently support book covers of various sizes. A third plate (Z is stationarily fixed to the plate 5 in the center of same between the guide plates 0. On the plate d rests the curved back of the book cover during the operation of the machine while the sides of the cover rest on the guide plates 0.

On the supporting plate Z) there are bearings c to support the rollers f. These rollers may slide up and down in the bearings to allow of the insertion of book covers of various thicknesses. Underneath the rollers 7 there are rollers g driven by a chain it from the main shaft 2'. A bevel gear on the main shaft c meshes with a bevel gear j mounted on a stud j which is in a bearing j on the table plate al On the shaft of the bevel gear j there is an eccentric to which a link 70 is connected. At the end of the link 70 there is a lever arm Z whose other end carries a vertical shaft Z in a bearing m. On the top end portion of the shaft Z a long horizontal arm a is provided. In order to substantially support the stud Z and the lever arm n a bearing m supported on the table plate a is.provided. The stud Z passes movably through the bearing m. At the other end of the lever arm a there is attached a divided support or holder 11 extending downwardly and carrying the brush or soft rubber 0 which passes over the book cover during the operation of the machine for the purpose of removing the excessive gold leaf or the like.

On the plate I) near its outer ends there are open boxes .9 for the purpose of receiving the gold dust which has been removed by the soft rubber or brush 0. The gold dust is drawn out of these boxes in the usual way by suction through pipes p which connect with a suction fan 9 which in turn is driven by sprocket wheels 1 and a chain T which sprockets 1" are connected to the main shaft by bevel gears W. In this way the collected excessive gold leaf may be easily recovered.

The front roller g is divided into sections 9 as shown in Fig. 4 to allow of space for the guide plates which, by their adjustment, render it possible to insert book covers of various widths. The roller mechanism draws in the book cover and the soft rubber or brush on the lever arm a cleans same. The book cover then falls through the opening in the supporting plate 5, above mentioned, into a basket or the like. The rollers f are in frictional contact with the rollers 9 when no book cover is between them. Vhen a book cover is inserted between said rollers it will be drawn in by the action of the rollers g which are power driven and the rollers f then rotate by reason of being in contact with the moving book cover. The main shaft 2' is rotated by means of a power pulley t mounted on said main shaft. The lever 91 which carries the soft rubber or brush 0 likewise is driven from the main shaft z as above described. By virtue of the eccentric is the lever 12 performs an oscillating movement and the soft rubber or brush passes over the book cover to and fro whereby a perfect cleaning of same is effected. The exhaust fan 9 for recovering the excess of gold leaf also is driven from the main shaft by the bevel gears r and sprockets r connected by the chain r Thus the feed rollers, the reciprocating lever with cleaning devices attached thereto, and the exhaust fan for recovering the excess of gold leaf are all. driven from one main shaft and power pulley and all that is required is to feed the book covers into the machine and remove the filled baskets into which the cleaned covers fall automatically. The machine therefore saves a great deal of wages and cleans the book covers more uniformly than they can be cleaned by hand. By the simplicity of its construction the machine may be operated by any unskilled person but produces uniform and neat work.
