- in the art to which it appertains to make and use the saine.
- My present invention relates particularly to spraying devices wherein a tank for containing the liquid to be sprayed is equipped with an air pump detachably applied thereto, and arranged to produce air pressure in the said tank. Thev invention is directed to improved means Jfor interlocking the several elements of the pump to the tank, and generally stated, consists of the novel devices and combinations of devices hereinafter described and defined in the claims.
The invention is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views. Referring to the drawings,
Figure 1 is a plan view showing the tank equipped with my invention;
Fig. `2 is a side elevation showing the upper portion only of the tank and its pump mechanism;
Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2 but with certain parts broken away and illustrating the construction of elements located below the said section line;
Fig. 5 is a section taken approximatelyon the same line as Fig. 4, butwith some parts removed.
rlihe tank is indicated by the numeral 6 and this tank, at the central portion of its upper side plate, has a rigidly secured internally threaded sleeve 7 for detachably supporting the pump mechanism.
The pump which is of the reciprocating cylinder and piston type, is adapted to be operated by hand and comprises a cylinder 8 and a piston 9, the rod of which is shown in the drawings, but the piston head of which is not illustrated, since it may be of the usual or any suitable construction. To the upper end of the piston rod 9 is a rigidly secured suitable hand piece 10, the lower end of the stem portion of which is provided y with outstanding diametrically opposite lock with the threads of the sleeve 7 to detach-- ably hold the pump cylinder in working position with the tank. A pliable gasket 13 is countersunk into the under surface of the outstanding iiange of the rim 12 and is seated on the upper edge of the sleeve 7.
A-cylinder cap 14 is detachably seated on the innermost portion of the rim 12 and is provided with outstanding lock lugs 15, as shown, three in number. In the horizontal plane of these lugs 15 the rim 12 is formed with an internal lock channel 16 having, at circumferentially spaced points, stop Ilugs or shoulders 17. Midway between the stop shoulders 17, the uppermost horizontal flange of the rim 12 is formed with lug entrance notches 18, through which the lock lugs 12, when turned into alinement therewith, may be moved' either into or from the said channels 16.
The cap 14 is also shown as provided with depending centering lugs 19 that engage with the interior of the rim 12 to center' said cap, in respect to said rim.
The piston rod 9 is arranged to reciprocate freely through an axial passage in the cap 14 and the said cap is formed with an internal lug channel 20 into which the lock lugs 11 are adapted to be turned. The uppermost inturned flange of the cap 14 is provided with diametrically opposite lug entrance notches 21 through which the lugs 11, when turned into alinement therewith, may be passed t0 and from alineinent with the said channel 20. Midway between the entrance notches 21 and within thechannel 20, the cap 14 is provided with' stop lugs or shoulders 22.
The important relation of the parts above described will be made clear by the following description of the operation, or use thereof.
When the rim 12 is applied to the sleeve 7 and the cap 14 is turned so that its lock lugs 15 are within the lock channel 16 (see particularly Figs. 3 and 5) which illustrate both a downward and inward camming action between the lugs 15 and the upper and outer walls of said channel.
When the tank has been properly changed,
vthe piston will be pushed downward to its i of pulling upward limit, while the lugs 11 are turned into alinement with the notches 2l, and thence, the lugs 11 are turned lnto the channel 20, thereby locking the piston down so that it can not be forced upward by the re-action of the compressed air in the tank.
he manner of releasing the piston for use is obvious. Frequently it is desirable to remove the entire pump piston from the pump cylinder without removing the cylinder from the tank. To accomplish this re sult, the hand piece 12 is gripped in one hand and the piston is rotated in a clock-Wise direction, in respect to Figs. 1 and 3, until the lugs 11 are moved past the coperating'entrance notches 21 and into engagement with the shoulders 22, and then, by constant rotation in the said direction, the cylinder ca 14 may be rotated until its lugs 15 are alined and then cap may be lifted from position by pulling upward on the hand piece 10, and will come away with the piston. If, l
and cap are to be again secured 1n worklng position in respect to the tank, the rim l2 may* be screwed into the sleeve 7, as far as it will go readily, by engaging the same with the hands, or it may e thus screwed into position simply by manipulation of the hand piece l0. By reference to Fig. 3 it will be noted' that with the parts as they are positioned, if, by manipulation of the hand piece 10, the parts are rotated in anti-clockwise direction, bear against` shoulders 22 and lugs l5 Will tightly screwing the rim l2 into the sleeve 7.
he above described lug der cap, in the one instance, and between the cylinder cap and the cap rim in the other instance, form a species of bayonet joints in which the lugs are removed when in intermediate positions in which there is an interlocking and stopping action when the lugs are rotated in either direction from such intermediate positions, and then unlock the said parts so that the several parts may be released or removed, either individually, or collectively. This arrangement is thought to be broadly new.
Vhat I claim is:
1. The combination with a tank and a pump comprising a cylind-er and a piston, of a cap rim secured to said cylinder and connectible to and disconnectible from Said tank by rotation,a cylinder` cap connected to said rim 'by an interlocking bayonet joint, and the rod of Said piston being detacha'bly connectible to said cap by a bayonet joint, said bayonet joints limiting the rotary movement of the connected parts, the one in respect to the other.
2. r1`he combination with a tank having a threaded sleeve, a pump cylinder, a pump piston, a cylinder cap, a cap rim secured to said cylinder and having threaded engage` cylinder cap having said lock channel through said lug entrance notches and engageable with said stop shoulders, said cap also having an internal lock channel with lu entrance notches and with stop shoulders intermediate of the lock entrance notches thereof, the stem of said piston having a hand piece and provided with lock lugs that are insertible into the lock channel of said cap through the entrance notches thereof and are rota-table into engagement with the stop shoulders of said cap.
In testimony whereof I aiiix my signature presence of two Witnesses.
