SUPPORTER FOR SI ERAYING-TOWERS.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed February 28, 1907. Serial No. 359,780.

To all whom it may concern:

Be it known that 1, DAVID SNE L,a citizen of the United States, residing at Gasport, in the county of Niagara and State of New York, have invented a new and useful Supporter for Spraying-Towers, of which the following is a specification.

This invention has reference to improvements in supporters for spraying towers, and its object is to provide an adjustable means for holding the spraying nozzles in any desired position whereby spraying compositions may be thrown on to trees infested with various parasites, or that are liable to become so infested.

The invention consists essentially in a tower-holding rod adjustable in a vertical plane around a horizontal axis, with means for holding the same in the adjusted position, together with a support for the structure with provision for rotating the entire structure on a vertical axis whereby the nozzle holder may be moved through a circular path in a horizontal plane.

The invention will be fully understood from the followin detailed description taken in connection with the accompanying drawing s forming part of this specification, in

' which,

Figure 1 is an end elevation of the machine; Fig. 2 is a side elevation; and Fig. 3 is a plan view of the machine with the towersupporting rod removed.

Referring to the drawings, there is shown a support for the tower comprising a horizontal ring or annular band 1 at two diametric ally opposite points of which are secured uprights 2-3 approaching each other toward the upper end and there secured to diametrically opposite points of a vertically arranged ring 4. The uprights 23 have braces 5 attached to them about midway between their upper and lower ends, and these braces are spread apart at their lower ends and are there fast to the band 1. Extending diametrically across the ring 4 in a horizontal direction and about coincident with the point of juncture therewith of the standards 23 is a cross-bar 6, and braces 7 connect the lower portion of the ring 4 with the standards 23.

Diametrically across thering 1 in line with the point of juncture of the standards 2-3 is a brace or bar 8, and through this bar extends a pivot 9 in the axial center of the ring 1, the pivot 9 entering whatever support the ring 1- may rest upon, whether the same be a wagon-body or any other means whereby the device may be transported from tree to tree.

Upon the axis or center of the ring 4 there is hung by means of a pivot 10 a bar 11, one end of which extends downward beyond the ring 4 and is there connected by a spring12 to a clip 13 fast on the ring 1, or, if desired,

on the bar 8, and this clip may be fixed in any position by means of a thumb-screw 14, i

or the frictional contact of the clip with the ring 1 may be sufficient. The other end of the rod 11 extends upward beyond the ring 4 to any desired distance and is designed to carry a tower 15 having a number of nozzles 16 above the upper end of the rod 11, and this tower may be secured to the rod 11 by means of suitable clips 17.

A spring 12 tends to move the lower end of the rod 11 until the rod and spring are about in line one with the other. Now, if the rod 11 be turned on its pivot against the action of the spring and the pin 18 be placed in one of the holes 19, of which there isa series formed through the ring 4, the tension of the spring will hold the rod 1 1 against this pin as a stop, and the tower will therefore be held in the adjusted position while the operation of spraying is proceeding. In order to facilitate the adjustment of the tower 15, this latter carries a manipulating handle 20.

When the operation of spraying is proceeding the operator may move the entire support about the pivot 9 to direct the nozzles to any point of the tree being sprayed that he may desire, and he may also adjust the rod 11 through any vertical are he may desire and there set it by'means of one of the pins 18 inserted in one of the holes 19 and the rod will there be held against accidental displacement by the pull of the spring 12.

Should it be desired to tighten or loosen the spring 12, the clip 13 may be moved to any desired point on the ring 1, or on the bar 8 if the clip be placed on this said bar.

It will be seen that by making the entire structure of band metal, it is made amply strong for the purpose and at the same time is so light as to be readily carried upon a wagon which may also contain the spraypum and the supply of spraying liquid. At the same time the cost of manufacture will be small because the parts may all be made of the band metal of commerce, put together by rivets or bolts, so that the only labor necessary in the construction of the device will be the cutting of the band metal into the roper lengths and the riveting together of the parts.

The rod 11 may either be made of suitably stiffened metal or of wood.

It will be understood, of course, that the structure may be carried upon a suitable support, such as a boat, behind the wagon.

1. A supporter for a spraying tower comprising a circular frame arranged vertically and having a peripheral series of perforations, a bar pivoted to the center or axis of the frame, stops adapted to said perforations and in the path of the bar or tower support, and a spring tending to hold the bar against a stop in its path.

2. A supporter for a spraying tower com prising a horizontal circular frame, a bar diametrically across the same, a pivot insaid bar in the axis of the circular frame, standards rising from diametrically oppo- 1 site points of said frame, a vertical ring} mounted on the upper ends of said stand- 1 ards, a rod for carrying the tower pivoted 3 in the axis of said vertical frame for move- I ment through a vertical arc, a spring coni l I l nected to the lower end of said bar and to a fixed point on the supporting frame, and a stop pin adapted to any one of a series of perforations in the vertical frame and arranged to be locked in the path of the towercarrying bar.

3. A supporter for a spraying tower com prising a horizontal frame movable about a vertical axis, a vertical frame supported thereby and movable therewith, a towercarrying bar supported at the axis of said vertical frame to move through a vertical arc, a stop adapted to any one of a number of perforations in said vertical frame and in the path of the tower-carrying bar, a spring secured to the tower-carrying bar at the end opposite that carrying the tower nozzles, and a clip adjustably secured to a fixed portion of the lower part of the frame and connected to the end of the spring remote from that secured to the tower-carrying bar.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
