Description
I Patented Oct. 16 19 28 ALN'I'QN SCHWIEBEN,
No Drawing. I
' for the traction surface of a belt pulley.
After making extensive research, in the field of invention relating to pulley construction, I have found that practically all pulleys in use today, allow a certain amount oi slip; ping of the belt over the surface, especially when the 'belt is not properly adjusted on is too loose. I I
This is objectionable as it permits a loss of power and makes it necessary to provide belt tight-eners, and to keep the belt comparatively tight at all times. It follows also, that this is objectionable because a tight belt causes undue wear on the bearings and shafts, and this decidedly shortens. the life of the parts.
What I propose, fabric covering for the traction surface of a pulley, the improved article having many.
advantages in that it will last a long time and will .prevent the belt from slipping, thereby conserving 25% to 30% of the power, obviatin the necessity of running the belt too tig t, and eliminating-the use of belt dressings, such as are injurious, to the belting material. The novelty ofthe inventionresidesmore particularly in a special compound whichlis provided for coating a fabric backing composed preferably of an open mesh muslin.
. In accordance with the foregoing statement, the principal element of the product is the muslin. Secondly, there is the special liquid coating compound provided for coating the opposite surfaces of the muslin in order to produce a product such. as operates as ,an efiicient covering for the pulley surface.
The compound embodies substantially eight in edients or constituents. These will be liste in order that they may be clearly understood.
First, I employ gum arabic, which is obtained from a species of acacia and this particular element is employed for use as a masticatory.
Secondly, I employ ground glue, which is used because'of its tenacious properties and further for the reason that it will adhere and stick readily to either, iron, or steel.

.tion, and because of its smoothing qualities. 1 Sixth, I employ, flour which-is used for B5 Seventh, I employ sugar to prevent the composition from becoming brittle, and to prevent it from crackin and breaking after it is applied to the cloth.
Finall I employ lampblack, which is .used for coloring and to retard the heat which is produced by the friction of the belt running against the covering.
It is preferable to use the following nan-v tities to about eighty square yards or un- The above in edients in the proportions 8 gallons of water, and are bolled until ,mm Y I Gum arabic 4 Ground glue '1 Alum 1- Lampblack 1 Isinglass 1 Flour I v 12 Sugar Sal soda 1' of the in redients become thoroughly intermin gled and dissolved.
Then, the composi warm liquid state, is applied to both sides of a highly porous stretch of unbleached mustion while still: a is lin through the medium of an appropriate brush. It is easy to spreadandthe cloth absorbs it quite readily. Assuming that the entire eighty square yards of muslin has been coated, it will be obvious that it must be allowed to stand until it becomes dry.
. The drying process takes from ten to twelve hours. When finished, the product simply looks likei'the cloth which has been painted black. Of course, the large piece is stripped or cut into smaller pieces such as I be appropriate for mounting on the particular pulleys by hand. Care should be exercised in applying the covering to the surface of the pulleys. To
5 begin with, the surface of the pulley must be perfectly clean. In fact, it is advisable to clean it with gasoline. Then the coated piece of cloth is put into hot water for a period of twenty seconds or so, and it is quickly removed and wrapped around the surface of hard and the ingredients employed in the covering have no injurious effects upon the belt whatever. In fact, the result is advantageous in that it prevents slipping of the belt. It allowsalso the belt to be run com- 2 paratively loose while obtaining suflicient traction. This eliminates wear and tear on the bearings and journal.
It is believed that by considering the description in connection with the drawings, a clear understanding of the invention will be had. Therefore, a more lengthy description is thought unnecessary.
Having thus described my invention, what I claim as new is As a new product of manufacture, a covering for the surface of a pulley, said covering comprising a backing member of unbleached muslin, and a liquid coating for said muslin, possessing adhesive properties for causing the muslin to stick to the surface of the pulley when applied and for subsequently producing tenacious belt traction, said coating comprising gum arabic, four pounds; ground glue, fifteen pounds; alum, one pound; lampblack, one pound; isinglass, one pound; flour, twelve pounds; sugar, four pounds; and sal soda, one pound.
In testimony whereof I afiix my signature.
