PETER W. REIFSNEIDER, OF LIMERICK, PENNSYLVANIA.

SPECIFICATION formingpart of Letters Patent No. 667,102, dated January 29, 1901.

Application filed June 19,1900. Serial No. 20,880. (No model.)

To all whom it may concern:

Be it known that 1, PETER W. REIFSNEIDER, a citizen of the United States, residing at Limerick township, in the county of Montgomery and State of Pennsylvania, have invented new and useful Improvements in Plows, of which the following is a specification.

My invention relates to plows; and the objects of the same are to provide a simple and eificient double and reversible plow-point and to provide a plow-point bar which can be quickly adjusted to use either end of the bar or to project the bar as it wears away in use. I attain these objects by means of the construction illustrated in the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective view of a plow embodying my invention. Fig. 2 is an under side view of the same. Fig. 3 is a detail sectional view through the moldboard. Fig. 4 is a sectional View of the plow-point bar and supporting-lugs. Fig. 5 is a perspective view of the adjustable share. Fig. 6 is a similar view of a fastening-plate. Fig. 7 is a perspective View of a bolt and wedge for holding the adjustable share. Fig. 8 is a detail perspective of the nozzle. Fig. 9 is a similar view of the seat for the nozzle.

Like numerals of reference designate like parts in the different views.

The numeral 1 designates the moldboard; 2, the landside; 3, the detachable housing or nozzle for the reversible point- bar 4, and 5 is the adjustable share. Upon the inner surface of the landside 2 a lug 6 is formed, said lug being of such size and shape as to provide a solid support for the side of the pointbar 4. Bearings or supports 7 and 8 are also formed on the inner surface of the landside, said supports being of different heights to support the point-bar 4 at the proper angle to the shaft-line. Spaced lugs 9 9 project from the inner surface of the landside, and said lugs are provided with registered apertures 10 to accommodate a pin 11. The detachable housing or nozzle 3 for the pointbar 4 has a flat under face 13 and a shank 15, which extends to the top of the moldboard and is seated in a recess 16 therein.

The reversible and adjustable point-bar 4 has its ends 4 and 4 formed into substantially wedge shape. The bar is substantially rectangular in cross-section and at its opposite edges is provided with a series of notches or apertures 4 for the pin 11. It will be noticed that the notches 4 are not located opposite each other on the opposite sides of the bar. The object of this arrangement is that the bar is not weakened by opposite notches, and I attain greater scope of adjustment by reversing the bar when said notches are located, as shown, in zigzag relation.

The point-bar4 when in place rests between the spaced lugs 9 9 and is supported at one of its edges on the bearings 7 8 and upon its side by the lug 6. Where the point-bar passes out of the housing or nozzle 3, it is supported at both sides and edges, as will be understood from the drawings. The pin 11 is inserted through the upper lugs 9 and then through the lower lug 9. In this way the pin is retained in place by its own weight and screwthreading is obviated.

The adjustable share 5 is provided with the inclined slots 18 and is secured to the inner lower edge of the moldboard by the two bolts 20, which pass through the slots 18 in the share and the square apertures 18 in the fastening-plate 18 The bolts 20 are screwed into the inner face of the moldboard, and the heads of these bolts are provided with apertures 21 to receive the wedges or keys 22.

The share may be adjusted outwardly as it wears away.

From the foregoing it Will be noticed that the point-bar 4 may be reversed and adjusted as it wears away. It will also be noted that the bar is firmly supported at difierent points in its length and that the means for holding the bars at any point of adjustment are very simple and can be quickly operated.

Having thus fully described my invention, what I claim is 1. In a plow, a landside provided with spaced lugs and alined apertures in said lugs, a reversible plow-point bar having notches in its opposite edges, and a pin adapted to pass through the alined apertures in the spaced lugs and engage the notches in the point-bar, substantially as described.

2. A plow comprising a landside having a supporting-lug, bearings of different heights, and spaced lugs upon its inner face, a housing at its point end, and a reversible point bar provided with Wedge-shaped ends and notched sides, said bar being seated between the spacing-lugs, and supported upon the lug and bearings and in the housing, and a pin for holding the bar in place between the spaced lugs, substantially as described.

3. In a plow, an adjustable share, comprising a plate having inclined slots, a fasteningplate secured to the inner face of the share,

HGSSGS.
