6 Claims.

invention relates to a liquid spraying device. and while it is of. general. application it is. especially intended for use in spraying; oil onto the leaf springs of motor cars.

It; is. an.- obiect. of this invention to construct a. simple yet efficient mechanism whereby a spray of: oil. may be injected with considerable force by the operator in the use of two fingers engaging a stationary handle and the thumb op--. erating a head mounted on the top of a reciprocable plunger against the tension of a spring which tends to. move the plunger in the oppo-v Sit direction. The extreme. simplicity of the construction and ease of operation are the distinguishing features of this invention which may be applied to a can especially constructed or to the cans of commerce which are provided with a screw threaded tubular neck'on which the device. is mounted.

With the above and other objects in view, which will appear as. the description proceeds, my me volition consists in the construction and arrange; ment of parts hereinafter described and claimed.

In the accompanying drawing, which forms a part of; this specification, I have illustrated a preferred embodiment of my invention and in which:

Fig. 1 is a vertical central section of the device.

Fig. 2 is a plan view showing the operating handle, taken on the line 2-4 of Fig. 1.

Referring to the drawing, Ill indicates a can preierably of a. size which can be conveniently carried in one hand. The same is provided with a screw threaded tubular neck l'l extending from the top thereof onw'hich a screw cap 12 is mount-v ed. (3 is a gasket between the top of the neck II and the cap. l2. Extending downwardly from the cap l2 there is a pump barrel l4 provided at. its. lower end with a, standing valve [5 which is pref-. erably of the ball type, as shown. At the upper end of the barrel ll is a tubular plug I6 which is suitably secured to the barrel l4 by a press fit. The upper end of theplug I6. is reduced and screw threaded as at l! and extends through a bore |2"in the cap l2 forithe reception of a nut I8 which holds the plug to the cap l2 and also a handle l9 disposed between the nut l8 and the top of cap [2.

The handle I9 consists of a pair of convex arms 2020 extending in diametrically opposed direc tions, being united by a perforated disk 2| encircling the reduced neck ll of the plug 16. Slidably mounted in the plug I6 is a tubular plunger 22 provided at its lower end with a suitable piston 2:3 and an, inwardly op mn va v 24 prefer bly of he ball t pe. T e plunger x en s, for some distance above. the can l and a mo nted its upper end a tubu ar can p o id d with a substantially flat or slightly convex top 2-5". A tubular member 26, leads from the head25 prefera ly at ri h a l thereto at whose outer end a su t le sp ay n nozzle 21 is mou ted, 28 is a screen member in the tubular member 26 to screen the oil during its passage to. the nozzle head 21.

Surrounding the upper part of the plunger 22v and interposed between the head 25, and the hut. H! is a helical spring 29 tending to move the head 25, and, the plunger 22- attached thereto upwardly. The pw d m vem t of t e pl er s imited. by a stop member 30 mou ed on the p unger 2: nd. adapted to engage t b tom of p us; E 3| is a perforation in the upper part oi barrel 1- to per i f ee ci cul tion o a r between. the upper pa t of th n a d; the an u r spa b tw en t plunger 2 d th ba rel UL It will be underst od t at n pla e of the can I en n the tubular neck of; the an. l0. the t p f. he. can ould be built gra ly wit the plu t, dispe s ng with the tubul r hoo and he screw cap and a special opening could be pro vided for filling the can with oil.

It is a great convenience in the operation of my device to be able to place the tubular member 26 with its nozzle 21 in various angular positions in respect to the axis of the handle Is. It is merely necessary to rotate the member .26 and the plunger 22 connected thereto upon the axis of the plunger to the desired position. The frictional co-efiicient of the spring 29 engaging the movable head 25 at one end and the stationary nut l8 at the other will hold the nozzle and the parts connected thereto in adjusted position so that it will require a conscious eilfort to rotate the nozzle 'into a' new position. The

' plunger 22 fits loosely in the plug I 6, permitting air to pass between them to compensate for the oil displacement inthe container, 7 a a I 7 Various changes in the construction and ar rangement of parts of my device may be made by those skilled inthe art without departing from plunger, a spring tending to move the plungerup-- wardly, and a stationary handle supported by" the container and comprising oppositely disposed arms adapted to be engaged by two fingers of the operator while the thumb operates the plunger by alternately depressing the head. 30
