HEAD FOR 'SlPHON-BO'TTLES.

SPECIFICATION formingpart of Letters Patent No, 289,063, dated November 27, 1863.

Application filed October 11, 1883. No model.)

To all whom it may concern.-

Be it known that I, JOHN BROWN, a citizen of the United States, residing at Medford, in the county of ll liddlesexand State of Massachusetts, have invented certain Improvements in Heads for Siphon-Bottles, of which the following is afull, clear, and exact description, reference being bad to the accompanying draw-' screwed down in place.

Siphorrbottles as heretofore constructed are objectionable, for the reason that it is found extremely difficult to so construct the head as to cause it to bear firmly on the washer at the top of the-bottle to make a perfectly gas-tight joint, and also at the same time hear at its lower edge directly upon the shoulder of the divided collar which encircles the neck of the bottle, an annular space being generally left at the outside joint, between the lower edge of the head and the shoulder or flange of the collar, which space becomes filled with dirt, and more especially with the polishing-powder used in cleaning the head,which is not intend ed to be removed from the bottle after being once applied thereto. Furthermore, the lower portion of the ordinary collar below the shoulder is always exposed to view, and often becomes marred by the tongs or implement used to grasp and hold it while the head is being screwed down thereover.

My invention has for its object to dispense with the outside joint between the collar and the head, and also remove the collar fromview, thus avoiding the aforesaid collection of dirt, which detracts from the neat and cleanly appearance of the bottle; and my invention consists in a siphon-head provided at its lower end with an apron or annular extension ,which extends down entirely over and conceals the collar upon the neck of the bottle, the collar being so constructed as to be held in place while the head is being screwed over it by a suitable implement adapted to engage with its under side, as hereinafter more particularly set forth.

In the said drawings, A represents a metallic siphon-head, which is provided, as usual,with a discharge-pipe, b, and a valve, 0, operated in the ordinary manner by a lever and spring.

B is the neck of the bottle, which is encircled, as usual, by a divided metallic collar, 0, provided, on its exterior surface, above its flange d, with a screw-thread, over which fits the corresponding thread on the inside of the bell-shaped portion 6 of the head A, whereby, as the head is screwed on, it is broughtfirmly down onto the washer f, placed, as usual, upon the top of the neck of the bottle, and a perfectly gas-tight joint thus secured. At the bottom of the threaded bell-shaped portion 6 of the head A, and formed integral therewith,

is an annular extension, 9, of larger diameter than the threaded portion 6, which forms an apron or covering -flange, which, when the head is screwed down in place, extends entirely over the collar 0 and conceals the same from view, together with the joint h, between the flange (1 of the collar and the bell-shaped portion 6, which joint has heretofore been on the outside of the head A, and consequently there is no annular space left on the outside to collect and become filled with dirt, as heretoforean advantage which will be readily appreciated by those using bottles of this description. As the annular extension or apron 9' extends down to or below the lower edge of V the collar 0, it is evident that the ordinary implement which has heretofore been used to grasp the collar around the outside and hold it while the head is being screwed ,on cannot be employed. I therefore provide the collar, on its under side,with two square notches, ii, for the reception of projections It It, formed on the jaws of a pair of tongs, D, Figs. 1 and 4, the jaws being properly shaped to fit around the neck of the bottle, as seen in Fig. 1, and allow the projections k to pass up under the apron g and enter the notches 17, when, by

tightly grasping the handles ll of the tongs, the collar 0 can be held firmly while the head A is being screwed down thereover.

7 Instead of providing the collar with notches and the tongs with projections, the latter may be provided with apertures or recesses adapted to receive pins or projections on the collar,

or any other suitable construction may be adopted whereby the tongs may be made to engage with the collar on its under side and hold it firmly, as desired,while the head is being screwed down thereover. Another advantage resulting from my improved construction is that no particular attention has to be paid to the thickness of the washer f, placed upon the neck of the bottle, as the parts are so constructed that the bottom of the threaded portion 6 will never be brought down into contact with the flange d of the collar 0. A

20 further advantage incident to concealing the collar 0 from view is that in case it should become indented or marred it will not injurethe appearance of the bottle.

What I claim as my invention, and desire to secure by Letters Patent, is-

In a siphon-bottle, the combination, with the head A, provided at its lower end with an annular apron or extension, g, of the collar 0, encircling the neck of the bottle and fitting within said apron, and provided with notches i, or equivalent device, to enable it to be held by a suitable implement applied to its under side while the head A is being screwed on, substantially as set forth. 1

W'itness my hand this 6th day of October, A. D. 1883.
