Specification of Letters Patent.
Patented Mar. 19, 1912.
Application filed October 7, 1911. Serial No. 653,319.
ing the construction of that type of builtup belt employing two or more plies of fabric reinforcement.
The object of my invention is to improve the construction of such a belt in such a manner as to secure in'the finished product a maximum driving grip upon a driving pulley, and also so as to resist to the maximum any tendency of the several plies to become loosened and separated, in the event of being heated, as by friction caused by the slipping of the belt, which sometimes occurs, particularly when the belt is heavily overloaded.
In the accompanying drawing Figure 1 is a conventional showing of a short length of my improved belt. Flg. 2 is' a cross section thereof.
The belt shown in the drawings illustrates 'what may be termed a five-ply belt, in that there are five layers or plies of fabric employed therein, although broadly the number of layers is immaterial, so long as there are two or more. The two outer layers or plies are indicated by the reference numerals 12. Between the several layers is located a binding-material, which in this instance is rubber, the same being applied to the contacting surfaces of the several plies in any suitable manner. lVhen the several layers have their contacting faces thus treated and forced into intimate contact, the entire belt is properly vulcanized or cured by heat. The exposed surfaces of the plies 1-2 are not treated with rubber, but instead one or both of said surfaces are impregnated with balat in any suitable Way. In the drawings I have indicated the rubber binding at 3 and the balata facing for the layers 12 is indicated at 45 respectively. Where the balata is applied to both surfaces the belt is reversible.
I have found that a driving belt in which the driving surface is treated with balata will cling to a pulley very much more effectively and will resist slippage in a much greater degree than would be the case if said driving surface were left untreated, or treated with rubber similar to the binder 3. I have also ascertained that a multi-ply belt in which the' several contacting surfaces of the several plies are treated with rubber properly vulcanized possesses great durability, since even though subjected to heat, such as develo ed by friction in the event of slippage whici may occur in the event of a heavy overloading of the belt, such heat will not impair the binding agent between the several plies to such an extent as to loosen the same.
From the foregoing it will be seen that such a belt as I have described possesses all of the advantages of the most effective multiply belt construction, in which the binding agent employed is rubber properly vulcanized or cured, and it further possesses an advantage over any such belt in that the driving surface specially treated in the manner I have described is far more efficient than the driving surface of a beltitreated only with rubber. V 7
By the use of such a belt as I have described, the employment of belt dressings is avoided, and in this respect a substantial advantage is gained, because it is an admitted fact that belt dressings afford only temporary relief in the event of slippage and work in a short time a positive injury to the belt.
It should be understood that the method of cutting'the plies and of arranging them for the purpose of building up the body of the belt, is not material to this invention, and may be varied in any well known manner.
In the event balata is applied to only one of the exposed surfaces, it would be preferable, of course, to treat the opposite side of the belt; that is, the exposed surface of the ply on the opposite side of the belt, with rubber or some other suitable protecting material. If rubber is to be the protecting material, it would, of course, be preferable to apply the same before the vulcanizing process.
What I claim is:
1. In a driving belt, a plurality of plies of fabric arranged surface to surface, a binding of vulcanized rubber between the adjacent surfaces of said plies, the exposed Surface of one of the outside plies being free face of eacl of the outside plies being free from said binding material, and balata imfrom sa d blndlng materlal, and balata im- 10 pregnating the said exposed surface of said pregnating both of said exposed surfaces of belt. said belt. 5 2.
