WHEEL FOR LAWN-MOWERS.

Specification of Letters Patent.

Patented Nov. 8, 1910.

Application filed. September 11, 1905. Serial No. 277,985.

To all whom it may concern:

Be it known that I, Janus H. AUnLn, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in the lVheels for Lawn-Mowers, of which the following is aspecification.

One of the principal objects of my invention is to attain a construction which enables me to manufacture the various portions of the devices hereinafter specified out of sheet metal in a rapid, accurate and economical manner, and at the same time preserve the full strength of the material and of the structure.

Other objects of my invention will be hereinafter apparent.

The several features of my invention and the various advantages resulting from their use conjointly or otherwise will be apparent from the following description and claims.

In the accompanying drawings making a part of this application,Figure 1 is a view in perspective of a wheel illustrating my invention. F 2 is a view partly in section and partly in elevation of the same wheel. Fig. 3 is a view of the stationary disk that covers at one side of the wheel, the space within the wheel, and afi'ords support for mechanism for operating the knives. Fig. at 1s a view of the disk at the other side of the wheel. This disk covers there the space within the wheel and adds strength to the Wheel. This disk rotates with the wheel. Fig. 5 is a View in perspective of the outer shell of the driving wheel. Fig. 6 is a view, in perspective, of the inner lining or inner shell, which is located within this ring por tion. Fig. 7 is a perspective view of one of the pieces that go to form the zigzag or serpentine channels. Fig. 8 shows, in perspective, a view of another of the pieces that may be used in the serpentine channel. Fig. 9 is an elevation of a portion of the inner portion of the Wheel, illustrating how these pieces that enter into the construction of the serpentine channel are connected to the inner shell of the wheel. The edges shown in sec tion belong to the flanges of the outer shell of the wheel. Fig. 10 illustrates in perspective the preferred make of box that holds a part of the reciprocatory mechanism that receives its initial motion from the.

wheel, and imparts it to that cut the grass, etc.

Similar characters of reference herein indicate corresponding parts.

I will now proceed to describe my invention in detail.

1 form the peripheral shell A of the wheel of sheet metal, substantially as shown. Thus formed, there is a peripheral tread A having raised cross projections A. These cross projections are to create friction between the wheel and the ground, so that the wheel shall not slip on the ground. At each edge of this peripheral tread is a flange. So there are two flanges, one indicated by A, and the other by the character A. Both of these flanges are integral with the peripheral tread A all being struck up or stamped out of single sheet of metal. lVithin this wheel I locate a lining or inner shell B. This is made of one piece of sheet metal. This lining is adapted to carry the serpentine chamber or track. The preferred mode of constructing it, so as to carry said channel is as follows: I stamp up little lugs or clip pieces B which when so stamped project inwardly toward the axial center of this shell. I form out of sheet metal pieces such as C, Figs. 7 and 8. The piece has a base C and flanges C C The free ends of these flanges at C are curved outwardly. These pieces C are attached to the inner side of the shell B, and when so disposed are located relatively to one another and to the shell B, as shown in Fig. 9. The track T formed thereby is continuous around the i11- ner periphery of the inner shell B of the wheel. The pieces C have openings C Through these openings are respectively received the adjacent lugs B of the inner shell B. These lugs after being so inserted are bent down, see Fig. 9, and constitute clamps, which respectively hold each piece C to the shell B. Some of these pieces C are also made to hold the outer shell firmly to themselves, and also hold the inner shell B in place against the outer shell A. For illustration: The piece C, of Fig. 7 is provided with end lugs C C. Openings A in the flanges A and A of the outer wheel shell A respectively receive these lugs. The latter are duly bent over, and when thus bent firmly hold the inner shell B against the outer shell A, and also hold their piece 0 to the cutting knives this outer shell A. The construction with the lugs C, as shown in Fig. 7 is the preferred one.

In Fig. 9, the lugs C are shown straight and inserted through the flanges A and A of the shell A. In Fig. 2, these lugs C are shown after having been bent down in place. When the lugs C are not needed, they will be omitted from the piece C. The latter will then appear as seen in Fig. 8.

The side of the wheel is composed of a sheet metal disk D, stamped to shape. This side D, see Fig. 4, has lugs D extending horizontally toward what may be termed its inner side. Openings A in the flange A of the outer shell A respectively receive these lugs D The latter are then bent down, see Fig. 2, and firmly hold this side D to the wheel rim shell A. This side D has preferably an annular rib D", which confers strength, and adds to the ornamental appearance of this side piece. The central portion D of this side piece D is made concave. This concave shape not only adds strength to the wheel, but also allows room for the nut or other means used to secure the wheel in place on the axle shaft F, and which is to be placed within the plane of that side of the wheel. Thus this nut, or other means, does not project out beyond this plane, neither does the shaft F itself project beyond this plane.

At the inner side of the wheel, I locate a disk E. This disk E serves to cover the adjacent side of the wheel. It also serves to support the mechanism whereby as the wheels revolve the serpentine track T communicates motion to the mechanism that directly operates the cutter bar. A part of the handle also can utilize the disk as a support and as a means for tilting the frame and cutter bar of the machine. These functions of the disk and said mechanism are already fully described in other applications for Letters Patent.

- The part E is struck up as shown. Great strength is thus imparted to it. An opening E through it is the one through which passes a reciprocating bar that receives motion from the serpentine track and communicates its motion through proper intermediate means to the cutter bar.

The openings E are for a part of the handle to engage, according to the inclination at which the machine is to be operated.

The central portion E of the disk E is concaved, as shown. This shape confers strength upon the disk and also affords room for the means that hold the disk from slipping laterally along the axle, and yet allow the axle to rotate within it. This disk is also preferably formed with an annular concave E As the preferred construction of the mechanism between the wheel and the cutter bar,

a guideway Gr, see Fig. 10, is employed, and

l this guideway supported by the'dis'k E,

I will describe this guideway and the mode of connecting it to the disk. The guides way consists of sheet metal bent so as to have a top G and sides G G It has also flanges G, G one at the lower edge of each side G Each flange G is parallel to the top G and. extends inwardly. The guideway is provided at one end with lugs G preferably two on a side. These lugs respectively enter openings E and E of the disk E, and being longer than the disk is thick, they when inserted project beyond the inner side of the disk. These projecting portions are bent down. The guideway is now securely connected to the disk, and the space within the guideway alines with the space of the openings E The diskal piece E, making the inner side of the wheel, is mounted on a hollow cylinder or shaft F. The preferred means for connecting the diskal piece E to this hollow shaft F is as follows his shaft F has near its end ascrew thread F The shaft F is passed through the central opening E of the disk E. Nuts F F* are located on the shaft, one on one side of this disk, and the other nut on the other side of this disk. These nuts are now screwed toward the disk, and clamp it securely in position.

The disk D, making the outer side of the wheel A, is duly secured on its shaft H, as follows :-The shaft H passes through the hollow shaft F and through a central open ing D in the disk D. The end portion of this shaft is provided with a screw thread H On this shaft His secured a nut H* located at the inside of the disk D. Another nut H is screwed on this shaft H and located at the outside of this disk D. This disk D is securely clamped between these nuts. The disk D is securely fixed so as to be stationary on and with this shaft H, not only by means of the friction of the clamping nuts H 11, but also principally by means of the detent D which is preferably integral with the disk D, and which extends into a channel H running longitudinally in the shaft H. The preferred means of preventing the wheel and this disk D which forms a part of this wheel from approaching the disk E and from coming into too great frictional contact therewith is as follows The hollow shaft F is continued beyond the nut F toward the nut H, and may impinge directly against it, but the preferred means, as shown, is a small tube K, which embraces the axle H and a washer K. The latter rests against the adjacent end of the tube F, and the tube K at one end is against the other side of this washer, and at the other end bears against the nut H Adjustment of the nuts F and F will serve to move the disk E nearer to or farther from the wheel as desired.

It is to be understood that on the other end part of the hollow shaft F is a disk similar to the disk E, and on the other end part of the shaft H is a wheel similar to the one shown herein. In other words, the machine will be substantially symmetrical. As the parts fully described are simply repeated at the other side of the machine, the description herein presented is deemed suflicient.

The clips or lugs of one piece entering the slots of the opposite piece and bent over, are the preferred means of connecting such pieces together, but other means can be employed. lVhen the clips or lugs and the slots are present, it is not essential that these clips or lugs should be upon the part shown, but they can be upon the opposite part and enter slots in the complementary part. The clips or lugs and the complementary slots can be varied as to the pieces they belong to, and be interchanged in any reasonable manner.
