A. SCHWEIZER. PROCESS OF AND MACHINE FOR MAKING GLUE AND THE LIKE.

ADOLPH SCHWEIZEB, CHICAGO, ILLINOIS,.ASSIGNOR TO UNITED CHEMICAL &

ORGANIC PRODUCTS (10., OF CHICAGO, ILLINOIS, A CORPORATION OF DELA- WARE.

PROCESS OF MACHINE FOR, MAKING GLUE AND THE LIKE.

Specification of Letters Patent.

Patented Oct. 14, 1919.

Application filed August 9, 1917. Serial No. 185,267.

To all whom it may concern:

Be it known that I, AnoLPH SoHwErzER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Processes of and Machines for Making G1lue and the like, of which the following is a specification.

My invention relates to improvements in a process of and machine for making glue, gelatin and the like.

In the usual process of making glue and gelatin, animal tissue, having first been properly treated,'is boiled in solution with water until a colloidal liquid of a gelatinous nature is obtained. This is spread out in thin sheets and chilled, after which it is cut into suitable size strips or slabs and dried and finally again divided into smaller pieces and properly prepared for the market.

One of the objectsof my mvention is to hasten and cheapen the process by omitting the step of cooling prior to the drying step 1n the process, by dehydrating 0r directly eliminating the proper quantity of moisture content, thereby producing the hardening.

efi'ect without the necessity of first cooling and subsequently drying the jelly-like liquid.

Another object of my invention is to provide a simple and eflicient machine for carrying my process into efiect.

Other and further objects of my invention will become readily apparent, to persons skilled in the art, from a-consideration of the following description when taken in conjunction with the drawings, wherein Figure 1 is a transverse section through the machine; and

Fig. 2 is a central longitudinal section taken on line 22 of Fig. 1.

In both views the same reference characters are employed to indicate similar parts.

A cylinder 5 is supported upon spiders 6, 7, 8 and 9. The two end supports are disks to close theends of the cylinders. The other vided on the top of the standards or end frames 15 and 16. 'Secured to the outer end of the hub portion 11, 'is a driving pulley 17, which may be rotated by any suitable means. The hub portion is perforated, as at 18, to admit heated air, steam or other heating agency or fluid into the interior of the cylinder 5, that may come through the pipe 19. Other perforations 20 in the hub are provided, through which exhaust steam may pass out of the cylinder, between the hub 11 and the steam pipe 19. A packing ring 21 is placed in the hub portion 11, centrally supports the steam pipe, 19, and prevents communication between the live and exhaust steam. Another similar ring 21 is placed between the steam pipe 19 and the hub cylinder 11 to prevent the steam or hot air from flowing backwardly from the pipe 19 without entering the interior of the cylinder 5. A jacket 22 surrounds the cylinder and is spaced apart therefrom to provide a space "23 through which hot dry air may -flow from the inlet 24 to the discharge out- A scraper, or blade 26, extends the let 25. full length of the cylinder and is pivoted at each end, as at 27, to the standards. 15 and 16 and is held in' yielding contact with the outer surface of the cylinder 5 by springs 28.

Y A strip of felt 29 or other suitable packing material is placed radially from the hub 11 to the outer diameter of the cylinder 5 to prevent the hot air that comes in through the inlet 24 from short circuiting across the diameter of the cylinder at its ends. A scoop-shaped receptacle 30 extends across the outer peripheral surface of the cylinder with its lower edge 31 in substantially direct contact therewith, and its upper edge 32, slightly removed from the contact of the cylinder. The scoop-shaped receptacle 30 is connected by a pipe 33 with a reservoir which contains a hot gelatinous liquid 34, that fills the scoop.

In carrying my process into effect, the cylinder 5, as illustrated in Fig. 1, is rotated anti-clockwise and hot air, steam or other heating agency is admitted through the pipe 19 into the interior of the cylinder so as to heat the cylinder 5 to a temperature that will not be injurious to the gelatinous film that is to be dried on the outside of the cylinder but preferably to a temperature tion.

higher than that of the contacting solu- As the cylinder is rotated, in the manner described, a film of liquid. from the scoop 30 will adhere to the adjacent outside surface of the cylinder 5, thereby uniformly covering the outer surface of the cylinder as it is rotated. The thin film of gluey substance adhering to the outer surface of' he cylinder encounters the hot air that will enter the conduit 24, and being in contact with the relatively hot wall of the cylinder 5, will rapidly give up its moisture to the traveling current of hot dry air,

' which will absorb adjusted as.

it and be exhausted through the opening 25. When the film of gelatinoussubstance thus formed upon the be cut back to a point 32 so that the cling-v ing, material, to the outer' surface of the cylinder, may pass by this point uninterruptedly, or this wall may be horizontally der, and for this purpose I have shown a plate 35 overlying the upper wall of the scoop and capable of being adjusted toward or from the outer surface of the cylinder 5.

The standards 15 and 16 may be properly spaced apart and so held by the rods 27 and 37.

While I have herein shown a single emthe material has be to regulate the thickness or amount of liquid that will cling to the c'ylinhand.

bodiment of my invention for the purpose of clear disclosure, it is manifest that changes may be made in the general arrangement and-form of the parts of the apparatus within the scope of the appended claims.

Having described. my invention, what I claim is i 1. The process of making glue or gelatin, which consists in boiling animal tissue, or similar substance, until the solution will coagulate, when cool; lifting the adhesive liquid thus obtained, while hot, from a body thereofby surface contact with a moving hot dry surf-ace against the action of gravity, to provide a single, smooth, uniformly continuous thick film; constantly moving the said surface and deposited film; passing a current of hot dry air over the entire surface of the film in a path parallel with the path of movement of the film whilemov'ing and continuously removing the film of dried deposit from the moving surface after it leaves the influence of the hot air.

2. A-machine for the'purpose described having in combination a rotatable drum, means to admit steam to the interior of the drum; an air jacket surrounding substantially 270 degrees of the exterior surface of the drum; air admitting and discharging 'conduitsat the respective ends of the jacket;

a glue receiving receptacle having one of its walls provided by the drum, its lower wall in substantial contact with the outside surface of the drum; a scraper .bearing upon the drum, said receptacle and scraper being within the zone unoccupied by the air conducting jacket. In testimony whereof ADOLPI-I SCHWE-IZER.
