Specification of Letters Patent.

Patented Nov. 4, 1919.

Application filed January 3, 1919. Serial No. 269,439.

To all whom it may concern Be it known that I, F. K0011, a

citizen of the United States, residing at Hill side, in the county of- Custer and State of' Colorado, have invented certain new and useful Improvements in Mowing-Machines, of which the following is a specification.

This invention relates to. harvesters, and more specially to mowers, and the object of the same is primarily to produce a simple machine of this type.

An additional object is to afford the neces sary adjustments.

Finally, due consideration has been given to the weight of parts and therefore the cxpense.

.Details are set forth below,and in the accompanying drawings,

Figure 1 is a plan view,

Fig. 2 is a side elevation with the rear wheel removed, being a section on the line 2-2 of Fig. 1, and

Fig. 3 is a detailed section on the hue 3-3 of Fig. 1. w

The tongue one is attached directly to the body 2 which is herein shown as a substantially triangular casting mounted upon a sleeve 3 through which passes themaln axle 4. On the latter are mounted the wheels 5 and 6, either of which may be provided with a ratchet to permit the machine to turn corners, although this simple expedient isnot illustrated. The drivers seat is shown at 7 in Fig. 2 and is omitted in Fig. 1. I will here say that the hub of the wheelu6 may be connected with the driving or basket gear described below by means of a clutch if desired and this clutch would occur at the point 8; but as the same is well known I have omitted it from the drawing and will describe this gear as mounted directly upon said hub.

From a block 10 mounted on the axle 4 a pair of bars lead forwardly and downwardly as at 11 in Figs. 1 and 3 and from a second block another pair of bars 13 lead forwardly I and downwardly beneath the body 2 as seen in Fig. 2, the front ends of all these bars be-. ing connected by a cross bar or sleeve 14 and the entire structure constituting a skeleton framework having an oblique brace 15. Pivoted on a pin or shaft 16 through said sleeve 14 is a casting 17 to which at 18 is hinged the runner 19 supporting the cutting apparatus broadly designated by the numeral 20.

Adjustment ofthe plane of the cutting apparatus is effected by means of an arm 21 rising from th casting 17 and connected by a link 22 with the lower end of a hand lever23 which may be mounted on any appropriate support such as a body 101' the axle, but which must stand adjacent the drivers seat 7. Then now this lever is manipulated, the entire casting and with it the "runner and cutting apparatus are turned .pivotally around the pin or shaft 16 in a manner which will be clear.

Adjustment of th height of the cutting apparatus is effected as follows: A triangular plate 31 has its lower end mounted on the shaft 16 just inside the casting 17 and its front corners connected by a draft rod 34 with the tongue or pole 1. Its rear corner is connected by a link 35 with a bell-crank lever 36 pivoted at 37 to thebody 2, and the upper arm of this lever is connected by another link 32 to a hand lever 33 pivoted on a suitable support and also standing in reach of a driver sitting on the seat 7. When new this lever is manipulated, the forward arm of the bell-crank lever raises the link 35 which in turn raises the plate 31 and pin or shaft 16 and casting 17, the plate turning a little on said pin by reason of the fact that it is connected by the draft rod 34 with the pole or tongue. If the arms of the bellcrank be proportioned about as seen in Fig. 2, a comparatively small movement of the hand lever 33 will raise the runner 19 and the cutting apparatus 20 completely off the ground and out of action. The skeleton framework consisting of pairs of bars 11 and 13 connected by the sleeve 14- will be raised by this adjusting mechanism, since the bell crank lever is pivoted at 37 on the body.

The driving mechanism for the cutting a paratus has been constructed with the idea of simplicity, lightness, and cheapness. The basket gear 40 is mounted on (or, as above suggested clutched to) the hub of one wheel and has a beveled ring of teeth 41 aroundits periphery. These mesh with a bevel pinion 42 at the upper end of a hub 43rotatably space as well mounted on an upright pivot 44 whose lower end is carried in a block 45 on the main axle 4 as seen in Fig. 3, and whose. upper end is braced as shown at 46 in the other views. Fast on the lower end of the hub is a large gear 47 which drives a pinion 48 at the upper end of what well may be called a crank shaft. The latter passes down through a bearing in the block 10 and its lower end carries a crank which is herein shown as a disk 50 whose crank is in the shap of a wrist pin 5L depending therefrom asseen in Fig. 3. WVhile any suitable connection between the driving mechanism and the sickle bar may be employed, I prefer to use a rock lever 52 pivoted at 53 beneath the lowermost of the left hand bars 11 and slotted at its rear end 54 to engage said crank or wrist pin; and th front end of this lever is connected by a link 55 with the sickle bar of the cutting apparatus, preferably by means of a pivot joint connection 56 as seen in Fig. 1 so that the cutting apparatus may be turned up alongside the machine on its hinge 18 as is often desirable in mowers.

Rotary movement of the basket gear is communicated through the pinion 42, hub 43 and large gear 47 to the pinion 48 of the crank shaft, and from the crank of the latter power is communicated through the rock lever and link 55 to the sickle bar of the cutting apparatus which is caused to reciprocate rapidly by means of the relative size of the gear 47 and the small pinion 48 which it drives. Therefore, as the machine progresses and the main wheel 6 drives the gear, the sickle bar is reciprocated in a manner which will be clear. Meanwhile adjustmentsare permitted as described above. If a clutch be inserted at the point 8 as suggested, the driving mechanism can be thrown out of action immediately at any time the operator desires; but the same results could be attained by disconnecting the link 54 at one end or the other and permitting the crank shaft and rock lever to run idly. It will be clear however, that this machine is one of simplicity, and the fact that it includes so few parts reduces its weight and its expense.

Attention is invited to the fact that the use of a basket gear so-called mounted on or connected with the hub of one wheel, and driving a pinion from its periphery, permits a rather large gear 47 to fit into said basket and effects a considerable saving of as weight. Moreover, all parts are opened and readily accessible, and dirt or .dust may fall out of them rather than collect within them.

The foregoing description and drawings have reference to the preferred form of my invention. It is to be understood that I may make certain changes in construction, arrangement and combination of parts, ma-

terials, dimensions, et certera, expedient and fall within the scope of appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a device of the character described, the combination of a main axle having supporting wheels at its ends, a horizontally extending tongue having a triangular body fixed upon its inner end and mounted upon said axle, of a plurality of pairs of bars connected at their inner ends to blocks which are pivotally mounted upon said axle, a transversely extending cross bar connecting the ends of said pairs of bars, an obliquely extending brace connected to said tongue at the rear brace, the forward ends of said braces being brought together and connected to one end of said cross bar, an upright pivot mounted upon said axle, the inner end of said second mentioned brace being connected to the upright pivot for reinforcing the same, a cutting means hinged on the remaining end of said cross bar, and drive means mounted upon said axle and said upright pivot and being connected to said cutting means for driving the same.

2. In a device of the class described, the combination of a main axle having supporting wheels at its ends, a basket gear connected to one of said wheels to be driven simultaneously therewith, a supporting hub movable upon said axle, an upright pivot carried by said hub and having a beveled gear meshing with said basket gear, said beveled gear being connected to a larger gear, a pinion meshing with said large gear and having a disk provided with a wrist pin, a lever pivoted upon said supporting frame and having a slotted end receiving said wrist pin, and a link connecting said lever to said cutting means, whereby as said basket gear rotates, rotary motion will be imparted to said gears and pinions so that the lever will be oscillated and the link will be reciprocated for driving the cutting means.

3. In a device of the class described, the combination of an axle having supporting wheels, a frame having a supporting tongue, bars connected at their forward ends by a transverse bar, a casting pivotally mounted upon said transverse bar, cutting means hingedly mounted upon said casting, whereby the cutting means may be swung vertically to an inoperative position when desired, driving means connected to the cutting means for operating the same, a triangular plate pivotally mounted upon said transverse bar, a link connected to one corner of said plate and to said tongue, a bell crank lever pivotally mounted upon as may prove the said frame, and having'a link connecting its 130 end thereof, a second end to an opposite corner of said triangular In testimony whereof I affix my signature plate, means for swinging said bell-crank in presence of two Witnesses. lever, whereby the bell-crank lever will pull upwardly upon said plate to swing the same WILLIAM KOCH 5 upwardly and lift the transverse'cross bar Witnesses:
