der pressure into a spraying device. In
such machines, there is a large amount of waste of the liquid pertiume due to compressed air being retained :in the spraying device rafter theatomizing operation has ,been completed.
One of the objects of any invcntionis to provide an air compressing pump i of the type referred to, which at the end of the air compressing operation will perm t t-he quiok escape of arr from the spraying device, thus at once cutting off the air pressure and permitting the perfume liquid which is still in the discharge pipe ofthe spraying device to siphon back into the liquid perfume container of the spraying device.
A further object of my invention is to provide in the :con'i'pressing cylinder a bypass through which the compressed air from the spraying device can escape as soon as the piston reaches the end of its compression stroke.
Still another object of any invention is to provide novel means for permitting the escape of compressed ainfrom the spraying device and which is readily applicable to machines now in use.

Mounted in thecap 31s a'disohargepiipe 5, which may i be flexible and whichextends into the liquid 2. i
My improved air compressingpump comprises .a cyl-inder 6 having at its compression end an air outlet comprising a pipe 'f, and at itsv other end having an air inlet 8. The
cylinder ;6 is provided with (an .air byepass consisting preferably o-fa pipe 9,, the-ends of which communicate with the interior of the cylinder 6., one :end of the by-pass being closely adjacent to the -.com pression end of the cylinder, and the other end .being spaced therefrom-a distance.gireater-thanthe thickness of the piston .hea. to be operated in the cylinder. w
A manually operated piston has a piston rod 10-reciprocative in the air inlet .8, the outer end of the-rod :having a fingerhold consisting of a button 11 attached thereto The inner end of the rod 10 :has fastenedto it an ordinary leather cup piston head 12, which is .reciprocative in the cylinder 6 between the air inlet .8 and the compressed an outlet pipe 7. To limit the compression stroke of the piston the rod 10 is arrangedto contact with the compression end of the cylinder 6. At such position of the piston, the piston head 12 .is disposed between the ends of the by-pass pipe -9, asshownin dotted lines in Fig. 2.
Apipe 13 has one end attached to'the air inlet pipe 4-of the liquid container 1, the other end of the pipe 13 being attached'to the outlet pipe 7.
In the operation of the invention, the operator pulls the piston rod 10 outwardly a full stroke, upon which air will pass the compressible piston head 12 to the left thereof, as viewed in Fig. 2. The operator then pushes the piston rod 10 inwardly until the inner end of the rod strikes the compression end of the cylinder. The air will be compressed in the cylinder, and will pass therefrom through the outlet pipe 7 and pipe 13 into the container bottle 1 through the inlet pipe t and the cap 3. The air pressure in the container above the liquid 2, will force the latter out of the container through the discharge pipe 5.
As soon as the piston head 12 passes to a point between the ends of the by-pass pipe 9, the compressed air in thecompression end of the cylinder 6, pipe 13,-and container 1 will pass from the compression end of the cylinder 6 through the bypass pipe 9 past the piston head 12, and will displace the atmospheric air, which has entered the cylinder at the outer end of the piston, which displaced air will escape from the cylinder through the air inlet 8. The flow, from the discharge pipe 5 will almost instantly cease, and as the pressure in the container lowers to atmospheric, the liquid which is stili in the pipe 5 will siphon back into the container 1, thereby avoiding much waste of liquid which would otherwise occur if the pressure in the container 1 were not thus quickly re duced to atmospheric.
Upon thenext outward stroke of the pistonv the displacing air which is at the outer end of the piston, will pass the latter and will again be compressed'upon the next inward stroke of the piston. Thus the compressed air, which becomes charged with perfume vapor, will he used over and over. and there will, consequently, be very small loss of such charged air to the atmosphere, thereby effecting a great saving when high priced perfumed is dispensed.
I do not limit my invention to the structure shown and described, as manymodifloat-ions, within theiscope of the appended claims, may be made without departing from the spirit of my invention. I
lVhatIclaim is 1. In a spraying device of the kind dc cribed, the combination with a container adapted to hold liquid and adapted to hold air under pressure above the liquid and having an air inlet, and a discharge pipe extending into the container and adapted to have its inlet end below the level ot said liquid, of an air compressing cylinder having an air outlet and provided with a bypass, tube communieatingwith said air inlet and said air outlet. and a piston having a piston head reciprocative in said cylinder and adapted to compress air in said cylinder and to force the compressed air through said air out-let, the ends of said by-pass being disposed in the cylin'der at opposite ends respectively of said piston head when the latter is at the limit of its compression stroke.
2. In a spraying device of the kind described, the combination with a container adapted to hold liquid and to hold air under pressure above said liquid and having an air inlet, and a discharge pipe extending into said container to a pointadapted to be below the level of said liquid, of an air compressing cylinder having a compressed air outlet and having a by-pass the ends of which are located at different distances from the compression end of the cylinder, a pipe communicating with said air outlet and said air inlet, and a piston having a piston head reciprocative in said cylinder and adapted to force compressed air through said outlet, the ends of said by-pass being disposed in the cylinder at opposite ends respectively of said piston head when the latter is at the limit of its compression stroke.
3. In a device of the kind described, the combination with a compressed air container and having an air inlet, of a cylinder hava compressed air outlet adjacent to its compression end and having an air lay-pass, a pipe communicating with said air inlet and said air outlet, and a piston having a piston head reciprocative in said cylinder and adapted to compress and force air through said outlet, the ends of said by-pass being disposed in the cylinder at opposite ends resoectively of said piston head when the latter is at the limit of its compression stroke.
In testimony whereof I have signed my name to this specification.
