SPECIFICATION forming part of Letters Patent No. 738,03 3, dated September 1,1903.

Application led November 7, 1901. Serial No. 81,516. (No model.) Y

To @ZZ whom t may @o7/toorn:

Beit known that I, ALvA THOM as HAYNES, a citizen of the United States, residing in Wheatland, in the county of Yuba, State of California, have invented a new and useful Mowing-Machine, of which the following is a specification.

My invention relates to improvements in mowing-machines, particularly with reference to the cutting apparatus; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a top plan view of a mowing-machine cutting apparatus embodying my improvements, the hangers in which the power-shaft is journaled being shown in section. Fig. 2 is a detail top plan View. Fig. 3 is a vertical transverse sectional view. Fig. 4 is an end elevation looking in the direction of the arrow o3. Fig. 5 is a longitudinal sectional View taken on the line 5 5 of Fig. 1 and lookingin the direction of the arrow thereon.

In the embodiment of my invention I provide a sickle-bar 1, the inner end of which is attached to a shoe 7 by means of bolts 10. The said shoe is preferably of the form shown and is provided on its inner side with a shield 17. The latter curves upwardly at its front end and at its outer side. The shoe 7is provided on its upper side with a pair of standards 9, which project inwardly and upwardly therefrom and are provided at their inner ends with bearings for a shaft 13. The latter rotates directly in hangers 12, which are clamped in the said bearings by means of setscrews let, and the said hangers form the connection between the cutting apparatus and themowing-machineframe. Thelatterisnot shown, as it forms no part of my present improvements. At the outer end of the sicklebar l is a dividing-guard 8, which also forms a shoe or runner. It will be understood from the foregoing description and by reference to Fig. 1 of the drawings that the standards 9, shaft 13, and hangers 12 form a pivotal connection between the mowing-machine frame and the cutting apparatus on the sickle-bar 1, which admits of the raising and lowering of the cutting apparatus. The shaft 13 is provided with a sprocket-wheel 15, whereby power is applied thereto and said shaft rotated, and the said shaft is further provided with a pair of eccentrics.

To the under side of the finger-bar 1 is secured a guide-bar 3, which projects forwardly therefrom and is provided in its upper side with a longitudinal guide-groove 3a. The lower cutter-bar 6 bears on the said guide-bar 3 and against the front side of the nger-bar 1 and is provided on its under side with a longitudinal guide-flange 6, which operates in the guide-groove 3a. The upper cutter-bar 5 bears upon the lower cutter-bar 6 and against the front side of the finger-bar 1 and has a longitudinal guide-flange 5a on its upper'side at its rear edge. i

A plate 2 forms a housing or cover for the upper cutter-bar, is provided on its under side with a guide-groove 2a, in which the guideflange 5fL operates, and is further provided with openings 18 for the admission of lubricant, as shown. The finger-bar 1 is provided on its upper side with hinge members 1a, and the plate or housing 2 is provided at its rear side with similar hinge members 4, and pintles 4.- being inserted in registering openings with which the said hinge members 1a 4 are provided. The housing-plate 2 is hinged on the finger-bar, so that the same may be raised to uncover the cutter-bar and permit the latter to be removed for the purpose of sharpening them or for other purposes. The said housing-plate is shown disposed in an elevated position in dotted lines in Fig. 2.

Vhen the housing-plate is in its operative position shown in the drawings, the same is firmly secured on the fingerbar 1 and in position to bear upon the upper cutter-bar 5 by screws 11, which also serve to adjust the said housing-plate to compensate for wear, as hereinbefore described. The inner ends of the upper and lower cutter-plates are respectively connected to the eccentrics 13L of the shaft 13 by means of pitmen 16. It will be understood that when the shaft 13 is rotated the upper and lower cutter-plates will be reciprocated and will move simultaneously in opposite directions.

Having described my invention, I claim- 1. 1n a mowing-machine, the combination with a shoe, of standards rigid therewith, hangers secured within the standards, a

power-shaft carrying eccentrics and having its terminals journaled in the hangers, said hangers forming the means of attachment t0 the frame of a machine, and the shaft forming a pivot for the shoe, a nger-bar secured to and carried by the shoe and having a guide, a loWer cutter-bar engaging the guide, an upper cutter-bar, a housing hinged to the finger-bar and constituting a guide for the upper cutter-bar, and pitmen connecting the cutter-bars and the eccentrics, substantially as described.

2. In a mowing-machine, the combination with a shoe, of standards rigid therewith, hangers secured in the standards, a shaft having its terminals housed Within the hangers and carrying eccentrics, said hangers con-
