Specification of Letters Patent.

Patented Aug. 15, 1905.

Original application filed April 15, 1904:, Serial No. 203,340. Divided and this application filed August 19,1904. Serial No. 221,402.

To (LU 10/1/0721, it vita/y concern:

Be it known that I, Louis L. MARTIN, ma chinist, of the city of Toronto, in the county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Coin-Controlled Apparatus for Vending Perfumes and other Liquids, of Which the following is a specification.

The object of my invention. is to devise a jet-pump for vending perfume adapted particularly for use with coin-controlled apparatus; and it consists, essentially, of a receptacle, a pump-barrel located within the receptacle and having one or more apertures in its sides, a plug secured within one end of the barrel and provided with a fine bore, a plunger fitted within the barrel and having its inner end adapted to close the bore in the plug, and a spring tending to maintain the plunger against the plug, substantially as hereinafter more specifically described and then definitely claimed.

Figure 1 is a side sectional elevation of my invention. Fig. 2 is a sectional plan of the pump-barrel and plunger.

In the drawings like letters of reference indicate the corresponding parts in the different figures.

This application is filed as a division of application, Serial No. 203,340, filed April 15, 1904:, and the constructions described hereinafter are intended particularly for use with the coin-controlled apparatus set out in that application.

I is a scent-receptacle. Within the scent-receptacle is secured the pump-barrel J, one end of which projects out from the forward end of the receptacle. Secured within this end is the plug 72., having a fine bore extending through it from end to end and communication with the interior of the pump-barrel. A small tube K connects with the bore in the plug and serves to direct the jet of liquid discharged by the pump, as hereinafter described. The inner end of the plug is preferably coneshaped, as indicated. Through the sides of the pump-barrel and near the inner end of the plug are formed one or more small apertures t', through which the perfume enters the interior of the pump-barrel. While one aperture if sufficiently long would suffice, I prefer to employ two or more set at varying distances from the plug it. The plunger L fits easily Within the pump-barrel, and its end is preferably provided with a small plug or insert j, of leather or other soft material,

which is adapted to close the bore in the plug when the parts are in the position shown in the drawings.

An operating-rod M is secured to or formed integral with the plunger, and its end is ex tended out through the rear of the scent-receptacle. The end of the operating-rod is provided with a small journaled friction-roller A), intended to be operated by the coin-controlled mechanism described in the application hereinbefore referred to. The coil-spring Z, secured to the scent-receptacle and the op crating-rod and plunger, tends to maintain the parts in their normal position.

The operation of the device is substantially as follows: By drawing back the operatingrod M one or more of the holes 6 will be uncovered to a greater or less extent, permitting a proportionate quantity of perfume to enter the pump-barrel. When the operating-rod is returned to its normal position by means of the spring l, a small jet of liquid is ejected through the bore in the plug It. While of course a certain quantity of the scent is likely to be ejected through the inlet-apertures 2', yet the larger quantity will pass through the bore in the plug, as described.

As the plunger is normally held tightly in contact with the end of the plug by the spring, the outlet is always tightly closed, the softleather insert making a liquid-proof joint.

The merits of this pump for coin-controlled vending apparatus lie in its extreme simplicity and cheapness of construction, also in the facility with which the output can be regulated by regulating the backward movement of the plunger.

What I claim as my invention is 1. In vending apparatus, the combination of a pump-barrel having a closed end provided with a fine bore and an aperture in its side; a plunger fitted within the barrel and having its inner end adapted to close the bore in the end of the barrel; and a spring tending to maintain the plunger against the end provided with the fine bore, substantially as described.

2. In vending apparatus, the combination of a pump-barrel having an aperture in its side; a plug secured within the said end of the barrel having an aperture therein; a plunger fitted within the barrel and having its inner end provided with a soft insert adapted to close the aperture in the plug; and a spring tending to maintain the plunger against the plug, substantially as described.

3. In vending apparatus, the combination of a liquid-receptacle; a pump-bar rel. located Within said receptacle and having one aperture in its side; aplug secured Within one end of the barrel and provided with a fine bore;

a plunger fitted within the barrel and having its inner end adapted to close the bore in the plug; a spring tending to maintain the plunger againstthe plug; and an operating-arm for the plunger extending-outside the receptacle, substantially as described. a

4. In Vending appa.ratus,.the; combination of a pump-barrel having a; plurality of apertures formed therein at varying distances from the end; a plug secured Within the said end and provided with a fine bore; a plunger fitted within the barrel and having its inner end adapted to close the bore in the plug; and a spring tending to maintain the plunger against the plug, substantially as described.
