BRAKE-BAND.

Applicationfiled May 17, 1916. Serial No. 98,151.

An important object of the invention is to provide a brake band of the above mentioned character, so constructed that the same will not have exclusive clamping or binding action with the drum, causing the wheels of the automobile to slip, and which will contact with the drum to properly re duce or stop its rotation.

"A further object of the invention is to provide a brake band of the above mentioned character, which is adapted to retain itself properly lubricated, whereby it is highly durable.

A 'further object of the invention is to provide a brake band of the above men tioned character, which will possess a high degree of spring or elasticity.

A further object of the invention is to provide a brake band of the above mentioned character, having a fibrous lining held in place by metallic inserts or segments, which are held against improper turning or twisting movements.

Other objects and advantages of the in vention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the' same.

Figure 1 is a side elevation of a brake band embodying the invention.

Fig. 2 is a transverse sectional view taken on line 22 of Fig. 1.

Fig. 3 is a perspective view of a metallic insert or segment, and,

Fig. 4 is a similar view of another metallic insert or segment.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral .10 designates a resilient metallic band. Arranged upon the outer side of the band 10 adjacent its free ends, are attaching elements 11, secured thereto by any suitable means.

The band 10 is bent outwardly at prefer-- ably equidistantly spaced intervals providing outwardly bulging curved portions 12. Arranged upon the inner surface of the band 10 is a strip of absorbent or fibrous material 13, which may be asbestos or any other suitable fabric. The strip 13has outwardly bent portions 14, projecting-into the outwardly bulging portions or pockets 12 of the band, as shown.

The numeral 15 designates metallic inserts or segments, preferably formed of bronze while other metal or material may be employed. Each insert 15 has an outer curved surface 16, adapted to contact with.

the outwardly bent portion 14 of the fibrous strip 13. Each segment has an inner curved surface 16, which is substantially flush or continuous with the inner surface of the strip 13, The insert 16 is provided with Specification of Letters Patent. Patented June 12, 1917..

a trunnion or bolt 17, preferably rigidly secured thereto. This trunnion or bolt is adapted for insertion through openings formed in the strip-13 and the ring 12 and its outer end is flattened or riveted for providing a'head'18, as shown. The turning movement of the segment is prevented by means of a lug or projection 19, formed upon its side 16 which extends into a recess 20 formed in the strip 13.

. The numeral 21 designates inserts or segments, preferably formed of bronze or other suitable material. These segments are arranged upon the ring 10 adjacent the attaching elements 11. Each segment is preferably of substantially the same thickness as the strip 13 and its inner surface is flush or continuous therewith, as shown. Each segment 21, shown in Fig. 3, is provided with a trunnion or lug 22, adapted for insertion through openings formed in the band 10 and attaching member 11. The outer end of the trunnion'or bolt 22 is flattened or riveted, providing a head 23, which serves to attach the segment to the band. The turning movement of the segment is prevented by means of a lug or extension 24 projecting into an opening or recess forme in the band 10. The segments 21 do not overlap the strip 13 but are arranged in end to end relation thereto.

From the foregoing description it is obvious, that during operation, the segments 15 and 21 may be brought into proper engagement with the drum, to retard its move meat or stop the same. The drum operates in oil and this oil is continuously fed to the segments 15 and 21 by the portions of the band 13 between the same, which band absorbs the o'il grease, or other lubricant.

It is to be understood that-the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape,

size and arran ement of arts ma 7 be resorted to Without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described the invention, I claim:

1. In a device of the character described, a band having portions of its material bent outwardly at spaced intervals to form 0utwardly bulging pockets, a fibrous strip arranged upon the inner surface of the band and having portions of its material bent outwardly at spaced intervals to fit within the outwardly bulging pockets, metallic face of the band and having portions thereof projecting into the pockets, metallic seg' ments engaging the strip adjacent the pockets and having their inner surfaces substantially flush with the inner surface of the strip, and means to attach the'segments to the band.

In testimony whereof I aflix my signature in presence of two witnesses.
