SPRAYING .aPPARA'rUs Thomas Harry Daly, Watervliet, Mich.

Application July 18, 1942, Serial No, 451 181- 9 Claims.

This invention relates to improvements. in spraying apparatus.

The main objects of this invention are:

First, to provide a power spraying apparatus for spraying orchards, vineyards, and the like which is highly elilcient and may be operated by a Single person, manual labor being reduced to aminimum.

Second, toprovide a spraying apparatus which may be. readily adjusted to vary thethrow or sweep of the spray heads and to direct the same.

Third, to provide a spraying apparatus. which is simple yet sturdy in its parts and may be aplied or adapted to. sprayer outfits comprising vehicles or carriages, power units, and pumps oftypes now in use.

Objects relating to: details and economies of the invention will appear from the description. to follow. The invention is defined and pointed cutin the claims.

A. preferred embodiment of the invention is illustrated in the accompanyingv drawing, in which:

Fig. 1 is a fragmentary side elevation. of a spraying apparatus embodying, my invention,

the standard being shown in collapsed position and various. parts being shown conventionally.

Fig. 2' i an enlarged fragmentary View partially in vertical section. showing various'structural details.

In the embodiment of my invention illustrated, the carriage designated generally by thev numeral l is designed to be drawn by a tractor or horses or hitched to a propelling vehicle, the hitch not being illustrated. An internal combustion, engine is conventionally illustrated at 2', 3" being the gasoline tank and 4 the radiator. A pump is conventionally shown at 5' and has driving; connection with an. agitator within the tank 6, the driving connection being shown at'l.

At the rear of the carriage, I mount a sup porting frame 8 for a standardor upright designated generally bythe numeral 9' which has a stepped bearing I0 whereby it is rotatably supported. A worm gear H- is secured to the standard at the lowerend thereof;

A manually driven adjusting worm i2 is supported to coact with this worm gear H, the shaft l3 of the worm l2 being supported bythe bearing l4 adjacent the worm, the shaft, l3 having a universal joint connection IE to the shaft 16 which is manually driven either by a crank or hand wheel, not shown, the shaft it being extended so that its operatin means is convenient to the operator controlling the tractor or'other means.

The standard. 9 in the. embodiment illustrated comprises a base'section H and a top section I8 collapsibly connected to the base section by means of the pivot l9 and the clamp 20, the clamp being adapted to embrace theupper endof thebasesection when the collapsible sectionis; inerected. position as. indicated by dottedlines in Fig. 1 and thus connected, a rigidconnection isprovided.

In this embodiment illustrated, I provide-a. pair of spray heads 2i, those illustrated being of the multiple nozzle type. These spray heads are car ried by tubular arms or spray pipes 22, which are connected by the fiexiblehose or conduits 23 to. the. sourceof supply under pressure, a pressure pumpinthlsem-bodiment.

The arms 22- are engaged by the-clamp 24 o I the bearing membersZE engaging. the pivots zfifwhich. are carried by collars 21 adjustably secured to; the.- standard by means of set screws 68. Itywill thus be noted that the pivots may beadjusted. vertically on the standards and the arms; 22! may beadjusted. longitudinally relative tothe pivots by means of the clamps; 2'1. By adjusting. the arms 22- long-itudinally,. thestroke of the spray heads or th are of movement. of the: spray heads may-bevaried.

The driving means: for the: sprayer arms or pipes 22 comprise a pair of beveled gears 28-and- 29 which are rotatably mounted onthe standard.

The beveled. gear 23 is provided with a hub. 30', the gear 29: being. arranged on this. hub and se' curedto-the gear 28- backto back.

A. crank. gear 31 is mounted on the. stub shaft 32. extending from the collar. 33 secured to the standard: by means: of the set screw 34. This crank gear has a crank pin- 35 connectedto apin- 36. on the spray headarm mounted. on thebase section of the standard. by means of. the connecting rod 31. The pin 35' is carried by a collar 38. whichis. secured'in its adjusted: positionslongitudinally of the arm 22 by means. of the set screw 39.

The link lii connects the lower spra head r to they upper spray head arm, the collar38 being. provided with ears toreceivea pin. 4| which engages an eye d2 in. the link 40, providing. a readily detachable connection, and permittingv the collapsing of the upper sectio'n'of the standard for] storage or in transporting articles from one place of use to another.

The supply pipesiilare controlled by valves l'il, a remote control rod it being provided'for these valves.

The crank gear is driven from the power plant, the driving connections comprisin a beveled driving pinion 4-5 which meshes with the downwardlyfacing' gear 28. This gear 55 is connected bythe sprocketcha'i'n 4'8} and the sprocket wheels 4"! and 48* tothe shaft 4e which is controlled'by the manually contwll'etlclutch 50; the remote control rod .31 being provided for that" purpose.

With this arrangement of parts, the apparatus is in complete control of the operator and a single operator may operate the tractor or other propelling means and control the spray heads as to direction, this being accomplished through the manually actuated shaft 16. The driving worm for this adjustment constitutes an effective lock for retaining the standard in an angularly adjusted position, at the same time it permits easy and sufliciently rapid adjustment to vary the direction of the sprayers. They are automatically swung vertically in any position of their adjustment and the angular adjustment in no way affects their operation and does not place them under any stress. The throw of the sprayers may be varied as has been described.

I have illustrated and described my spraying apparatus in an embodiment which I have found very practical. I have not attempted to illustrate or describe certain embodiments which I contemplate as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.
