SUCTION-CUP Foe MILKING-MAcHINEs.
Specification of Lettei's fizifent.
Patented Aug. 4', 1914.
To all whom it ma concern:
Be it known that I, ()1'10 A. Motors HA'UER, a citizen of the United States; residing at Watertown, county of Jefferson, and State of Wisconsin, have invented new and useful Improvements in Suction-Cups for Milking-Machines, of which the following is a specification.
My invention relates to improvements in suction cups for milking machines, with especial reference to milking machines of the eneral type shown and described in my ormer Patent Number 887,212, dated May 12 1908. a
The object of this invention is to provide a form of construction in which the teat will be expanded during the suction interval instead of being compressed or constricted as is the case with the suction on s heretofore in common use. Also to provi e simple and eii'ective means whereby abnormal distention of and injury to th'e teat will be avoided. Also to provide simple and inexpensive means for adapting the cup for teats of various sizes, regard bein also had for sanitation and the number 0 parts to the device being therefore reduced to the minimum and so arranged that they can be readily separated and cleansed.
In the drawingsFigure I is a vertical sectional view of a on embodying my invention. Figs. 2, 3 an 4 are detail vertical sectional views illustrating interchangeable teat engaging members.
Like parts are identified by the same reference characters throughout the several views.
The body A of my improved cup is provided with a removable upper section or mouth piece B, which is referably' screwed to the outer surface of tlib body A near its upper end. The body wall is provided with an exterior shoulder at C, above which the wall of the body is made comparatively thin and provided with one or more perforations D communicating between the interior of the cup and the annular space fornled be tween this thinner portion of the wall and the removable section B. At thenpper margm of the bod wall,- itis prov idea with an interned flange E.-
A collar F, provided with u wmuy turned flange G att'top and bottom; receives a flexible lining member H which preferably co'fnptises a piece of rubber tubing inserted through the collar F and having its ends bent outwardly and engaged over the flanges G,- as shown, whereby the tubing is held in posltion upon the collar by its own resiliency; The tubin is normally of less diameter than the diameter of the collar F, so that its central portion bulges in'wa'rdly from the coilalr, leaving a cavity H between it and the collar. The collar is provided with apertures F, which eor'nmun'icate be tween the cavity H and the cavity G between the collar and the annular wall of the member B. At its upper end, the section B is provided with an inturried flange B which serves as a clamping member for the collar F, a washer I being preferably interposed in a position to bear upon that portion of the rubber lining member H which is also interposed between the flange B and the collar F. A suction tube J leads outwardly and preferably downwardly from the cavity G through the wall of the section B of the cup, and a flexible hose pipe K will be connected to the lower erid of the member d, the suction being applied through the hose and the milk being also withdrawn there through. I
Vith the above described construction, a piilsating or intermittent suction may be applied by means similar to that shown and described in My above mentioned former patent, but with a different efl'ect within the cup. Owing to the fact that in my improved cup' the bottom is closed and the subtion applied to the interior of the cup through the holes D, it is obvious that the cup will first fill with milk at least to the level of the holes D. During the suction interval, the vacuum will be most pronounced in the cavities G and H. The walls of the flexible te'a't engaging member H will thereupon the teat and allowing it to expand as] p a free passage of milk through the. milk lieved, the wall H moves inwardly and 'applies a gentle pressure annularly to the up-- per portion of the teat which also tends to expel the milk therefrom.
To adapt the device for teats of dlfifllfillt sizes, I employ interchangeable collars F, f and f, as shown in Figs. 2, 3 and 4. These collars are all exactly alike except that they are of diiferent-diameters and are provided with flanges G, g and g ofdifi'erentwidths. The circular outer margins of the flanges G, g and g are all substantially the same diameter so that any one of these collars may be clamped between the fiangesB and E. To substitute one collar for another, therefore, it is merely necessary to unscrew the section B from the body section A of the cup, remove the collar F from the section B, and insert a collar of diflerent diameter, each of said collars bein provided with a flexible compression mem loer H, as above-described. The sections A and B will then be again screwed together until the substitute collar is securely clamped in osition with Suficient pressure to render the same air tight at the joints, the member H serving as a packing where it extends over the surfaces of the collar flanges.
It will be observed thatthe milk must pass through the holes D into the cavity Gin order to reach the outlet duct J. It is therefore obvious that the degree'of vacuum will be greater in the cavities G andHi than it is in the interior of the cup. The difi'erenoe in the degree of vacuum established in these cavities and that established in the cup will depend largely upon the relative capacity of the holes D and that oi thesuction tube or duct J. But even if the holes D are large,
the vacuum will still be greatest in the cavities G and H, and will be established first in those cavities when the suction is ap lied.
The cu being full of milk, there will 9 no tendency to expand the lower portion of the teat and very little tendenc todraw it downwardly into the cup, a though there will, of course, be a slight downward pull. In this respect, my invention difiers from all ordinary suction cups in which there is a strong downward pull exerted upon the teat which frequently draws it into the outlet and causes serious injur Owing to the fact that the vacuum is rst established in the cavities G and H, it is obvious that the annular pressure of the member H upon the teat will be relieved before the suction is applied within the cup through the holes D.
ll claim- ---v f ,I 1. A closed bottom suction cup for milk mg machines, havinga flexible teat engag- 1ng annulus in its up er portion, the upper and lower margins 0 which are expanded outwardly and secured to the cup, said .cup

3. T c combination with a suction cup for milking machines, having a closed bottom portion, of a set of removable teat engaging members of diiierent diameters, each comprising a rigid annular support adapted to e secured to said on and a flexible wall of less diameter exten ing therethrough and having its ends expanded and secured to said suppbrt. I
