1 Application November 19,1957, swarm. 597,433 r (cl,2'zz 114).'
My invention relates to improvements in remote control actuators for pressurized dispenser cans of the type having a spray nozzle head depressible to release the pressurized contents of the can.
The primary object of my invention is to provide a practical device for holding such' dispenser cans of poisonous insecticide and depressing the spray nozzle head from a safe distance, and which is adapted for use with pressurized dispenser cans of diiferent sizes.
Still another ObJfiCtlS to provide a device for the above purposes which is simple in construction, inexpensive to manufacture, and easy to handle and operate.
To the accomplishment of the above, and subordinate objects presently appearing, my improved remote control actuator comprises, as its basic components, an elongated barrel having hand-grip means at its rear end and a sliding actuator blade at its front end, a can holder at the front end of the barrel for supporting a pressurized dispenser can beneath the actuator blade, trigger operated means carried by the barrel for sliding the actuator blade, and means on the barrel and blade for camrning the blade downwardly to engage and depress the spray nozzle head of a pressurized dispensing can positioned in the holder, all as set forth in detail in the following description, defined in the appended claims, and illustrated in the accompanying drawings in which:
Figure 1 is a view in side elevation, partly broken away and shown in section, of my improved remote control actuator in the preferred embodiment thereof with a pressurized dispensing can positioned in the can holder;
Figure 2 is a view in plan;
Figure 3 is a view in front elevation;
Figure 4 is an enlarged fragmentary view in vertical longitudinal section taken on the line 44 of Figure 2;
Figure 5 is an enlarged fragmentary view in side elevation, partly broken away and shown in section, of the rear end portion of the barrel and parts of the trigger operated means;
Figure 6 is a view in vertical section taken on the line 6-6 of Figure 4; and
Figure 7 is a perspective view of the actuator blade detached.
Referring to the drawings by numerals, my improved remote control actuator, as illustrated, comprises an elongated tubular barrel 3 of any suitable light strong metal having at the rear end thereof a pistol-type hand grip S and forwardly thereof a depending auxiliary hand-grip 7. Intermediate the hand-grips 5, 7 a depending trigger 9 is pivoted in the barrel 3 by a transverse pivot pin 11 and depends through a bottom longitudinal slot 12 in the barrel 3 for swinging forwardly and rearwardly. The trigger 9 is operatively connected, by means, presently described, to the actuator blade 15. The actuator blade 15 is of elongated rectangular shape and suitable metal and is longitudinally slidable forwardly and rearwardly in the front end and longitudinally of the barrel 3 in diametrical position therein with a bottom edge portion 17 sliding in a longitudinal bottom guide slot 21 in the front endof the barrel 3. A bottom edge notch 22 in the rear end portion-of the actuator blade 15 forms a stop shoulder 23 on thejactuatorblade 15 engaging the while urging said bladeforwardly;
A pull rod 29 operatively connects the trigger 9 to the actuator blade 15 to slide said blade 15 rearwardly. For this purpose, the pullrod 29 is terminally pivoted to the trigger 9 and to the rearend of the actuator blade 15, as at 31, 33 and inclines upwardly from the trigger 9 into the barrel 3 through a bottom slot 35 in said barrel. The trigger 9 is provided with a plurality of apertures, as at 37 for adjustably pivoting the pull rod 29 to said trigger to lengthen or shorten the degree of endwise sliding .of the actuator blade 15 rearwardly, as occasion may require. i i a Coengaging. camming means for moving the actuator blade 15 bodily upwardly andvdownwardly of the barrel 3 in response to longitudinal movement of the actuator blade 15 in opposite directions comprises a transverse diametrical camming pin 39 in the front end of the barrel 3 extending through a slot 41 in said blade extending obliquely transversely of the blade.
The cam holder 40 comprises a hollow cylinder 43 of a diameter to hold commercial pressurized dispensing cans of different sizes therein, as at 45. A longitudinally extending leaf spring 47 in the cylinder 43 is fixed at its ends, as at 46, 48 to said cylinder and provides means for holding cans of different diameters adjacent one side of the cylinder 43 and frictionally locking a can 45 in said cylinder. A bottom collar 49 is longitudinally adjustable in the cylinder 43 to seat cans 45 of difierent lengths with the spray nozzle head 51 above the cylinder.
A bracket 53 on the rear side of the cylinder 43 provides for attaching the holder 40 to the front end of the barrel 3 with the spray nozzle head 51 below the actuator blade 15. A set-screw 50 in the collar 49 holds said collar in adjusted position.
The bracket 53 comprises a longitudinal web 55 on the upper portion of the cylinder 43 extending above said cylinder and having a longitudinally split sleeve 57 thereon for sliding on barrel 3 and clamping thereto by a wing bolt 58 in ears 59 on said sleeve.
A set collar 61 on the barrel 3 is provided and against which the sleeve 57 may be slid and rotated on the barrel 3 to center the spray nozzle head 51 below the actuator blade 15.
The operation of my invention will be readily understood. The can 45 is placed in the cylinder 43 of the holder 40. The holder 40 is attached to the front end portion of the barrel 3 by sliding the sleeve 57 rearwardly on said barrel and clamping said sleeve 57 in place against the set collar 61 with said collar adjusted on the barrel 3 and the holder 40 rotated on said barrel so that the spray nozzle head 51 is centered beneath the actuator blade 15. The can 45 may then be rotated in the barrel 43 to orient the spray nozzle head 51 in the desired direction. Then with both hands grasping the hand-grips 5, 7 the trigger 9 is pressed rearwardly to cause the actuator blade 15 to slide rearwardly, whereupon, said blade 15 will be cammed downwardly to depress the spray nozzle head 51 for spraying. Of course, the can 45 is adjusted in the cylinder 43 vertically so that the spray nozzle head 51 engages the bottom edge 17 of the actuator blade 15 before the trigger 9 is operated, as best shown in full lines in Figure 4, so that when said actuator blade 15 is depressed, the spray nozzle head 51 will be depressed by said "Paitented'Ju ly 7, 1959 blade. Upon release oflthe trigger 9, the spring '25 will cause the actuator blade 15 to slide forwardly and cammed upwardly against barrel 3 into normal position by the pin 39 and slot 4-1 and the pull rod 29 will be actuated, in a manner whichwill :be cleanby the actuator blade 15 to swing the trig ger back to starting position.
I continuous swa s slssir dh r g e 9 m b locked in rearwardly pulled position by a hook equipped chain 65 "attached at one end, as at 67 to the hand grip 5. This results in the actuator blade 15 being locked -in its downwardly cainmcdposition to hold the spray :nozzle head 51 depresseduntil trigger 9-is unlocked.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications :and changeswill readily occur to those skilled in the art, itis not desired to limit the-invention to the exact construction and operationhown and described, and accordingly all suitable modifications and equivalents may be resorted, falling within the scope of the inventionas claimed.
