6 Glaiins. (01. 285-1083 This invention relates to improvements in clamps and particularly to a pipe clamp. More Specifically, the invention concerns a quickly attachable and detachable clamp for securing a spray nozzle or the like to a pipe.

The invention herein is especially applicable to spraying machines involving the use of pipes having a plurality of nozzles at spaced locations thereon for applying weed killing fluids, insecti- (aides and the like to plants.

An object of the invention is to provide a simple and effi'cient clamp for tightly securing a spray nozzle to a supply pipe.

Another object of the invention is to provide novel clamping means for securing a spray nozzle or jet to a supply pipe wherein the clamp is quickly and easily removed to allow cleaning of the supply pipe and nozzle parts. This is particularly important in a spraying system for nsecticides and plant treating fluids because many such treating fluids rapidly contaminate the feed lines, and a great many nozzles must be removed and replaced after cleaning, so that time is an important factor. I

Other objects and advantages of the invention will become clear from the following detailed description when read in conjunction-with the accompanying drawings whereihi Figure l is an elevation of a sectionofp'i'pe having a spray nozzle attached-thereto'by clamping means embodying the features of the present invention; v I Figure 2 is a section taken on the line 2-2 of Figure 1; and v Figure 3 is a perspective view of a portion of the clamping structure in the form of a saddle member adapted to be. carried by the spray nozzle to straddle the pipe.

In the. drawings; the numeralv IIlide'sig'nates an elongated pipe provided with a plurality of orifices at spaced! locations lengthwise thereof, one of which is iri'd'icatedat II injfigure 2'. Such a pipe forms the boom of a mobile spraying machine adapted for spraying row crops and other vegetation, treating fluid being supplied through' the pipe ID to be released at spaced locations from the pipe through the openings l I. A spray'nozzle generally designated at IZ i's' provided at each of the openings I I in the pipe to discharge the treating fluid.

As pointed out hereinbefore, a number of different kinds of treating fluids, many of which contaminate the nozzles as well as the pipe and the openings therein, are utilized and discharged from the nozzles I2. Frequent cleaning of the pipes and nozzles is therefore required particular- 1y when changing from one treating fluid to another, and this requires removal and replacement of each individual nozzle from the pipe. The present invention was designed to provide a quickly removable and attachable clamp to facilitate such cleaning.

Nozzle I2 is of generally conventional construction and comprises a threaded pipe portion I3 having a broadened base [4 and a restricted portion I5 adapted for insertion in one of the apertures II of the supply pipe. Base member I4 is separated from the pipe by a washer I6 of rubber or the like. Pipe portion I3 is adapted to be received in an opening I'I provided in the transverse bight portion I8 of a generally U- shaped saddle member I9. v I

The upper end of the pipe I3 is closed by having resting thereupon an insert 2|] having a base portion 2| covering the opening at the upper end of pipe l3 and a restricted part 22 extending up wardly and provided with an orifice communicating with the pipe I 3. Insert 20 is held in place upon t he pipe I3 by a nut 23 threaded upon the pipe I3. Nut 23 further serves to secure the saddle member I9 to the nozzle I2, the bight portion I8 of the saddle member being confined between the base I4 of the pipe I3 and the nut 23.

Saddle member I9 is provided with

legs

24 and 25 adapted to straddle the pipe Ill and to engage the sides thereof. One of the legs 25 of the-sad dle member. I9 has a cut-out portion forming a clip or latch part 26 for a purpose hereinafter set forth. r

The lower ends of the legs '24 and 25 extend below the pipe II] on the side thereof opposite the nozzle I2 and at their lower ends are apertured at 2T and 28 to receive an arm 29 of an L -shaped locking member 30 having another arm 3| extending generally at right angles thereto. Arm 29 is adapted for rotation in the openings 21 and 28 in the saddle member on an axis below and spaced from the periphery of the pipe I!) as clearly indicated in Figure 2.

Arm 29, as also clearly shown in Figure 2, is arched or bent, and in the solid line position is in engagement with the pipe I0. In this position the saddle member I9 and the locking member 30 securely hold the nozzle I2 in position on the pipe III. In this position likewise the arin 3| of the locking member 30 cooperates with the latch element 26 to hold the locking member against rotation and to hold the nozzle or jet securely to the pipe. Saddle member I9 is preferably of spring steel and the latch element 26 bends outwardly slightly to receive the arm 3| and is curved somewhat to hold it in place.

Dismantling and removal of the nozzle from the pipe is accomplished simply by rotating the member 30 using arm 3| as a lever to the dotted line position indicated in Figure 2. The member 30 may then be removed by withdrawing the arm portion 29 of locking member 30 from the apertures 21 and 28 in the saddle. The nozzle l2 may be easily removed and taken apart so that the pipe and the nozzle parts may be cleaned. Replacement then is accomplished very easily and quickly so that spraying may be resumed with a minimum loss of time. Also, due to the arched shape of both of the arms 29 and 3| of locking member 30, either arm may be utilized for insertion in the openings 21 and 28 of the saddle member.

From the foregoing description it should be evident that a novel clamping means has been devised for securing a spray nozzle or the like to a supply pipe. The advantages of such a device become readily apparent when it is realized that a great many nozzles may be attached to a supply pipe at spaced locations thereon for covering as much of an area as possible during spraymg.

Having described the invention it should be understood that modifications may be made therein without departing from the spirit of the invention or the scope of the appended claims.

What is claimed is:

1. In combination with a nozzle or the like for attachment to a supply pipe having an opening therein for communication with the nozzle, a U-shaped saddle member carried by the nozzle adapted to straddle the pipe when the nozzle is in registry with the opening therein and having legs apertured at their ends, a latch part carried by the saddle, an L-shaped locking member having one arm extending through the apertures in said saddle and arched to form a cam surface engageable with the surface of the pipe opposite the nozzle, and the other arm serving as a lever for rotating the locking member, said latter arm being cooperable with the latch part to hold the locking member in place.

2. In combination with a nozzle or the like for attachment to a supply pipe having an opening therein for communication with the nozzle, a U- shaped saddle member carried by the nozzle adapted to straddle the pipe when the nozzle is in registry with the opening therein and having legs apertured at their ends, and an 'L-shaped locking member having an arm extending through the apertures in said saddle and rotatable on an axis spaced from the periphery of the pipe, said arm being bent and rotatable into and out of engagement with the periphery of the pipe to lock the nozzle and saddle assembly to and release it from the pipe.
