noward lrAi-nolikochland, Applicatlon october 9,1836, Serial No.-: 1l 4,911 1 Claim. (01. 14-2318) This inventionrelatesto a pulley-like structure such as is used 1forieed wheels or tension wheels, and particularly tofeed wheels or tension wheels of the type 'in'which the peripheral 15 groove for receiving the strand, cord orthe like is formed by two series of radially-extending with the arms ononeside of the groove having a staggeredrelation-tothe arms on the other side of the groove.

Q .10 Oneof the objects of the invention is to provide a novel feed wheel of this type which is simple in construction and which can be inexpensively manufactured and also to provide-a feed wheel having a rim oneach side of the groove 15 integral with the arms.

' My improved feed wheel or tensionwheel is made from two similar disk-like members of sheet material, each having a central body portion and a plurality of arms extending outwardly from the body portion in radial directions and a rim portion connecting the ends of the arms, the

body portion, arms and rim portion of each memher being integral with each other. The two members are assembled with the body portions thereof in registering engagement, and the arms ofeach member are so shaped that a portion of each arm of each disklike member enters a space between two adjacent arms of the other disk-like member so that the arms of the two disk-like members have a crossing relation. The outer ends of the arms of each member flare outwardly and. the rimportions of each member also flare outwardly, whereby the pulley is provided with a peripheral v groove with interrupted side walls, each side wall having openings opposite the solid portions of the other wall.

In the drawing wherein I have shown a selected embodiment of the invention;

Fig. 1 is a view of one of the disk-like" feed 40 wheel members; 1

Fig. 2 is a view of the other feed wheel member' sembled to make the complete feed wheel; 45 Fig. 4 is a section on the line M, Fig. 3.

My improved feed wheel comprises the two similar members I and '2. each of which is stamped'out from sheet"- material, preferably sheet metal. Each member comprises a central portion 3 havinga plurality ofarms 4 radiating therefrom, and a narrow, continuous rim section, 5 integral with thearms and connecting the outer ends thereof. Each arm 4 of each member is deformed by'being bent laterally as indicated 55 at 6, thereby forming. ashorter arm section I4 some a sinuous course whereby there is provided an excellent gripping or frictional engagement between the wheel and the cord. The narrow 1 1g. 3 is a side view of the two members as-'.

sirable way.

which connects to the central portion 8 and inciines in one directionrelative to the plane thereof and a longer arm. section II making an angle with the shorter-arm section I4 and which inclines in theopposlt'e direction relative to the plane'of the central: portion. 'Theiarms of each member are spaced from each'other: by a distance' slightly greater. "than the width of the arms of the other member and the two members I and 2 are assembled' wlth the central portions 3 of the two members' inregistering relation, as shown in Fig.4, and-with the ofiset portion I of each arm of one member occupying the spaces 1 between the arms ofj the other member, as best seen in Fig. 4. ,With this arrangement the arms of the two members haves. double crossing rela- Gil tion, the shorter arm sections ll of one member crossing those of the other member and the longer arm sections" of each member likewise crossing those of'the other member- This crossing relationof the longer arm sections I! forms a V groove 8 having interruptedside walls, each side wall having openings formed by the spaces I in the -disk=like members and the openings in eachside wall being opposite the solid portions of the other sidewall formed by the arms 4. 'The V groove thus provided has the solid portions of its two walls in staggeredrelation so that when a cord or'strand is laid in the groove it will ascontinuous rim sections"! have the advantage that they facilitate the feeding or laying ofi the cord in the groove. v

The two members I and 2 may be secured together'in their assembled relation in any suitable way. Asherein shown thesemembers are mounted on a hub I0 which is adapted to be securedto a shaftor other-support. This hub is shown as having one end II reduced in diameter and the. central portions 3 of the members I and 2 are provided with a central opening I! of a size V to fit" over the hub portion II of reduced diamthereby locklng'the'two wheel members in place.

These wheel members, however, might be spotweldedtogether or secured together in any de- The complete feed wheel is thus made up of two similar sectionswhich when assembled prov vide a V groove having-smooth edges, but with thev arms I of the two members having a staggered crossing'relation which, as stated-above, B5

10 feeding it forward. 1

A wheel embodying-my invention is also well suited for use as a tension wheel.

I claim:

A feed wheel comprising two similar disk-11k 5 members of sheet material, each having a central portion, spaced arms extending radially from the central portion, and a narrow continuous rim portion connecting the ends of the arms, each arm being bent to present a shorter inner arm section connected to the central portion and in- 011111118 in one direction relative to the plane thereof and a longer outer arm section connected to the rim portion and which inclines in the opposite direction relative to the plane of the central portion and thereby makes an angle with the shorter arm section, said disk-like members being assembled with the central portions in registering engagement and with the apices of the bent portions of the arms of one member occupying the spaces between the arms of the other member, and with the longer outer arm sections of the two members having a crossing relation and forming between them a V groove having interrupted side walls, each side wall having openings opposite the solid portions of the opposite side wall.
