. UNITED STATES PATENT orricnf HENRY J WIEGAND, OF MILWAUKEE, WISCONSIN, ASSIGNOR TO THE CUTLER-HAMMER 1VIFG..CO., OF MILWAUKEE, WISCONSIN, .A CORPORATION OF WISCONSIN.

HANIh-WHEIEL.

To all whom it may concern:

Be it'known that 'I, 'HENRY J. WIEGAND', a citizen of the United States, residing at Milwaukee, in the. county of Milwaukee and State of'Wisconsin, have invented new and useful. Improvements in Hand VVheels, of

. which the following is a full, clear, concise,

and exact description, reference being had to the accompanying drawing, forming "a part of this specification. v

My invention relates to improvements in "hand wheels, and has for its object to im-.

prove the construction of the hand wheel. disclosed in my former Patent, 'No. 821,272,

dated May22, 1906'. I

.One feature of my present invention resides in the construction of a rim which is Figure 1 is a bottom plan view of the wheel." Fig. 2 is a sectional-view taken'on line 2-2, Fig. 1, and Figs. 3 and 4 are detail views.

The'hand wheel illustrated is formed entirely of sheet metal, with the exception of the hub. The rim' is preferably formed in two parts, an upper member 1 and alower member 2. The members land 2 comprise stamped circular plates or rings so 'bent transversely as to form a rim substantially circul'arin cross-section when the same arefitted together as illustrated. In practice I' prefer to make the upper member of wider material than the lower member, so that when the same is .bent transversely, as illustrated, the curve of its cross-section is greater than a semi-circle. This renders the rim'of greater strength than by forming the two members alike. Furthermore, by forming the upper member as described,

" the edges of both members are hidden when the rim is viewed from the top. Owing to the fact that the two members are curved Patented Mar. 7, 1916.

. Application filed October s, 1908. Serial No. 456,802.

substantially concentrically, they may be placed together, edge to edge, on the outside to form a substantially smooth and continuous surface without the necessityof any special preparation of their edges. In practlce I prefer to have the inner edge of the upper member overlap the inner edge of the lower member, inasmuch as the ap pearance ofthe wheel is not marred thereby, and this arra'ngementpermits the parts to be more easily assembled. The two members are held together in the. manner here- The rim is mounted on inafter described. a spider, which preferably comprises three arms 3 radiating from a substantially cir{ cular central-portion 4. The arms Bare preferably formed integrally with theportion 4, the entire spider being stamped from sheet-metal. For the purpose of strengthening the arms and giving the same th appearance of being solid, the same are curved .transverselv, their edges-being hiddenwhen the wheel is viewed from the top. The ex tremities of the .arms 3 are flat and are secured to the inside of the upper "member of the rim, .preferably'by means of rivets 5. The lower member of the rim has notches stamped therein to permit the insertion of the ends of the arms 3 in the upper member of the rim and' 'to form tongues 6. The tongues 6 are'bent downwardly to engage the under side of the arms 3 and are secured thereto, preferably by solder. It will thus be seen that the-two. members of the rim are held togetherlby securing both of the same to; the arms 3. The central portion 4 of the spider is secured by rivets 7 to the annular flange 8"of ahub 9. The hub is preferably formed of cast-metal and provided with a socket or recess 10 for the re-' ception of a shaft. A screw 11 threaded into the side of the hub provides means whereby the same may be locked to the shaft.

In order tostrengthen the spider and relieve the strain on the rivets 7 when the wheel .is in use, I" provide the central portion 4 with downwardly extending flanges 12, adapted to fit tightly around the flange 8 on the hub. The provision of the flanges l2 adds greatly to the strength of-the wheel. Projecting outwardly from" one of the flanges 12 is 'a -pointer- 13, referably stamped integrally therewith. i

It will thus be seen that a hand-wheel constructed in accordance with my invention, has-the appearance and all of the advantages of a solid wheel, while the l same may be; produced at a much smaller cost.

Of course, my inventionds not limited to the specific construction illustrated, and various modifications maybe made therein -without de arting from the spirit thereof. I

l Having t us described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A hand wheel comprising a spider havingradial arms and a hand rim secured to the extremities of said arms and-having a gripping space betweeneach adjacent pair of said arms, said-rim comprising a plurality of transversely curved metallic rings rigidly secured to the armsof said spider to form a ring substantially circular in cross section.

2. In a hand wheel, the combination with a spider having radial arms, of a hand rim formed of transversely curved sheet metal rings rigidly secured to the arms of said spider to form a ring substantially circular in cross section, the ends'otsaidarms being concealed within said rim. r

3. In a handwheel, the'combination with a spider having radial arms,of a hand rim formed of a pair-of transversely curved sheet metal rings rigidly secured to the arms of said spider to form a ring substantially cir cular in cross section, the outer edges of said rings being flush and the inner edges thereof being overlapped. I

4. In a hand heel, the combination with, Y

a spider having radial arms, of a hollow hand rim-substantially circular in cross-sec-' tion and formed of a pair of sheet-metal rings, the inner edges of said rings overlapping, andthe outer edges thereof being flush, one of said rin'gs having apertures for. re ceiving the .ends or. said arms and having tongues secured to said arms, said arms being secured to rmgs.-

. 1 6., In a hand wheel, the combination with a sheet-metal ,spider having radial arms c'urved transversely, of'a hollow hand rim substantially circular in cross-section and formed of a pair of sheet-metal rings, said rim having apertures formed therein for receiving the ends of said arms.

7. In a hand wheel, the combination with a sheet-metal spider having radialarms curved'transversely, of a hollow hand rim substantially circular in cross-section and formed of a pair of sheet-metal rings, one

of said rings having apertures formed there- 1n for receiving. the ends of said arms and having tongues formed thereon and secured to said arms, the other of said rings being riveted to saidarms.

8. A hand wheel having a spiderformed of sheet metal andprovided with arms radiating from the central portion thereof and a hub secured to the central portion of said spider, said central portion having its edges between said arms bent to form flanges to engage the sides of said hub. i

9. A hand wheel having a spider formed of sheet metal and provided with arms radiating from the central portion thereof, said arms being curved transversely and said central portion having its edges bent to form angularly disposed flanges continuous with said arms, and a hub secured to the central portion of said spider between the flanges thereof.

In witness whereof, I have hereunto subscribed my name in the presence of two witnesses.
