FAN-BELT.

Specification of Letters Patent.

Application led May 26', Y1919. Serial No. 299,810.

To all who-m it may concern.'

Be it known thaty I, NAPOLEON J. Poivr- LANGE, citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Fan- Belts; and l do hereby declare the following tobe a full, clear, and exact description of the invention, sueh as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to belts generally but is particularl)v directed to an improved fan belt. Fan belts. as is well known, are generally used in connection with automobiles, for driving the fans.

(ieneraltv stated the invention consists of a novel device and combination of devices hereinafter defined and described in the claims.

The. beltV is made up of a main body of leather or other suitable beltin; material and a heavy backing of felt. rI`he leather body is provided with several laterally spaced longitudinal rows of perforations that open dire tl \Y against the felty backing.

ietween the rows of perforations and on theouter side thereof the leather belt and the felt backing are connected by rows of stitches. i

ln the accompanying drawings which illustrate the invention like characters iudicate like. parts throughout the several views.

Referring to drawings:

Figure l is a. plan view of the belt portions thereof being broken away;

Fig. 2 is a sideelevation of those portions of the belt shown in Fig. l;

Fig. 3 is a plan view of the belt showing the ends thereof disconnected; and

Fig. t is a detailed view in side or edge elevation showing the elements of the belt coupling.

T he leather body of the belt is indicated by the numeral 5 and the felt backing thereof is indicated by the numeral 6. The numeral 7 indicates the rows of stitches vthat connects the leather body 5 and felt backing 6. The numeral 8 indicates the perforations in the leather belt 5. These perfor-ations 8, in the two rows are preferably staggered so that they give a better suction action on the pulleys.

So far as this invention is concerned, the ends of the belt may be connected by any suitable form of coupling, but as shown the coupling comprises two

plates

9 and 10.

These two plates are riveted or otherwise rigidly secured to the ends of the leather belt 5, and the backing of felt (3 is terminated short of these plates, so that it does not overlap the secured ends thereof. The, plates 10 have a T-shaped head 10 that is 'engageable with the hook-like overturned ends 9 of the plate S). As stated this belt is especially designed for use as a fan belt. Fan belts. as it is well known, are subject to considerablel oil and this oil should be removed from the faces of the pulleys.

rl`he perforations inthe body of the belt perform two functions to wit; in the first .place they give a limited suction on the. pulleys which increase the traction of the belt,

and in the second place they `pick up the oil might be of other absorbent material capa.

ble of performing the .function stated.

The stitching of the belt, it will be noted,

Patented Nov. 11, 1919.

does not interfere with the flexibility thereof v but gives the belt increased central strength. This' improved belt has been put into actual use and has been found highly' etti* cient for the purpose it had in view.

What I claim is:

l. A belt made up of va body havingperloo In testimon.)Y whereof I allix my signature in presence of two Witnesses.
