Patented J an. 16, 1917.
Continuation of application Serial No. 806,774, filed December 15, 1913. This application filed March 2,
- 1916. Serial No. 81,688.
To all whom it may concern.-
Be it known that we, PHILIP MUELLER and ANTON (J. SCHUERMANN, citizens of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented new and useful Improvements in Wall-Fittings for Cocks, of which the following is a specification.
This invention relates to an improved wall fitting for cocks, and has for an object to provide a fitting wherein a canopy may be used for giving the fitting a finished and neat appearance, and wherein the canopy will adjust itself to the angular displacement of the cock relative to the wall or sink back, so that it will seat about its entire edge against the wall or back.
This invention is a continuation of our application Serial NO. 806,774, filed December 15, 1913.
The canopies generally employed at the present time are screw-threaded to the shank of the faucet, and in order that the canopies may be tightened against the wall through which the faucet shank extends the canopies are provided with angularly disposed wrench-receiving faces by means of which the flanges are turned and forced into engagement against the wall. It is found that this arrangement and structure is unsatisfactory in that the canopies are marred and disfigured by reason of the application of wrenches and the like thereto and by reason 'of the crushing of the canopies when adjusted to hold the cock or faucet from movement.
To overcome these disadvantages is the prime object of this invention, and in carrying out these objects of the invention the improved fitting is provided with a relatively strong collar adjustable upon the shank of'the faucet and adapted to engage the wall so as tofirmly hold the faucet in place, and to provide a canopy mounted independently of the collar upon the shank on which it may be adjusted without turning or without the application of tools or the like thereto into position to house the retaining collar and close the opening in the wall, and the canopy is of a thin, bendable metal so that it may adjust itself by body distortion to the angular position of the faucet relative to the wall or sink back.
In the accompanying drawings-Figure 1 is a vertical sectional viewtaken through the improved wall fitting. Fig. 2 is a trans,- verse section on the line 2-2 of Fig. 1,- showing enlarged the relativepositions of the canopy and the retaining collar. Fig. 3 is a detail perspective view of the retaining collar. Fig. 4 is an edge view of the collar. Fig. 5 is a vertical sectional view of a slightly modified form of-fitting. Fig. 6 is a transverse section-,taken on the line 6-6 of Fig. 5. Fig. 7 is a detail perspective view of the modified form of retaining collar shown in Fig. 5. Fig. 8 is an edge view of the retaining collar of Fig. 7. Fig. 9 is a vertical sectional view through my improved wall fitting showing another embodiment thereof. Fig. 10 is a view similar to F g. 9, but showing the position of the parts when the faucet has become angularly displaced relative to the wall.
' Referring to these drawings, wherein like characters of reference indicate similar parts throughout the several views, 10 indicates a service pipe projecting into an opening 11 in the wall 12 into the end of which pipe is screwed the shank 13 of the faucet 14. The shank 13 is provided in a usual manner with iron pipe threads for attachment to the (-orres 'umding threads of the service pipe.
(arricd upon. the shank 13 is a. canopy or flange 15 which is formed of a thin, bend able metal to permit yielding or body distortion without cracking or breaking when strain is placed thereon. The canopy is provided at its outer or smaller end with a cylindrical neck portion of considerable length,
and the end of the neck portion is turned inwardly to provide a flange 16. An annular packing ring 17 of rubber or other suitable compressible and anti-slipping material is received by the neck portion of the canopy and is forced against the inturned flange 1(l'by means of the flanged collar 18 adapted to fit within the neck portion in the manner shown in the drawings.- The packing ring is adapted to frictionally engage and bind against the shank, and the ring is of .considerable thickness, being substantially direction, but at the same time the canopyis retained from accidental displacement by jarring or the like; i
Within the canopy 15 is located a retaining collar 19 carried upon the shank 13 and being provided with radial lugs 20 engaging against the outer side of the wall 12 for the purpose of holding the shank firmly in position when adjusted. This collar 19 is mounted for adjustment upon the shank 13, and any-suitable means may be employed for holding the collar upon the shank in adjusted position. In Fig. 1 the means employed for holding the collar upon the shank comprises a relatively fine threaded portion 21 on the shank immediately adjacent the iron pipe threaded portion which engages in the service pipe. The collar 19 is provided with internal threads adapted to engage the threads 21 of the shank and not only hold the collar 19 in position when adjusted but also provide means for feeding the collar 19 inwardly against the wall and drawing out the shank l3 and the end of the service pipe so as to firmly hold the faucet or cook 14 rigidly 'in place.
From Figs. 2, 3 and 1 it will be particularly noted that the ret.ining collar 19 is provided with a pluralit of spaced apart radially extending lugs 20 having preferably flat faces with the inner end of the collar 19 and adapted to lie flat against the outer face of the wall or sink back 12. By providing these spaced apart rigidly extending lugs a strong collar is provided which is adapted to span practically any opening and insure ample support for the flange and prevent. the coupling from rattling and from distortion. Each of the lugs ,20 is provided with a radial socket or opening 23 adapted for the reception of a spanner wrench, or nail, or some suitable relatively sharp instrument which will catch in the openings or pockets 23 and turn the entire collar 19. The advantage of thus providing for an engagement with the collar in a radial direction, and by means of these relatively thin instruments, is that the collar 19 may be tightened to the desired degree whereas in prior structures such collars could not be used for the reason that when the canopy is pulled forward to expose the collar and its parts the the wall is so small that it will not admit of j the application of a wrench of proper size to turn the collar.
In assembling the wall fitting shown" in Figs. 1 to 4, the shank 13 is engaged through the opening 11 and with the service pipe 10 in the usual manner by rotating the faucet and its shank until the desired adjustment is had between the shank and the service pipe. The canopy 15 is moved outwardly of the shank 13 from the Wall 12 by'apply- 22 at their. rear side flush spacebetween the canopy and.
ing considerable pressure thereto at diametrically opposite points in a direction paral' lel to the axis or longitudinal center of the shank 13, so that there will be no tendency for the canopy to assume an angular position relative to the shank which would distort the canopy and prevent slipping. A suitable implement is inserted in the openings of the lugs 20, and by means of which the collar 19 is turned upon the threaded portion 21 of the shank. As the collar approaches the opening 11 the lugs 20 bear against the wall 12 and draw the service pipe into the opening to retain the same from vibration. The canopy 15 is now moved inwardly against the wall 12 to close in the collar 19 and its lugs and to cover the opening 11.
Another means for fastening the retaining collar upon the shank and in place against the wall is shown in Fig. 5 wherein the shank 13 hasno finely threaded portion but a smooth outer surface over which the retaining collar 19 slides, the latter having also a smooth inner surface. The collar 19 is provided in one side with a point screw 2e extending radially therethrough and adapted for binding engagement at its inner end against the smooth outer surface of the shank 13*. This structure is disclosed to advantage in Figs. 6, and 8. From these figures it will be seen that the collar 19 is provided with radially extending lugs 20 provided with flat wall engaging faces and being reinforced by webs or braces 25 projecting from the rear faces of the lugs and extending outward from the body of the collar 19.
If the retaining collar of Figs. 5 to 8 inclusive is employed the same is. pushed against the wall while the shank 13 is drawn through the opening 11 and when the. de-
.sired tension is had the point screw 24 is is pushed toward the wall to completely inclose the collar 19 and its lugs and to cover the opening 11.
Referring now to Figs. 9 and 10 wherein is disclosed a slightly different embodiment of my invention, 26 designates a T-coupling for connecting the sections of the service pipe 10, the T-coupling having an internally threaded projection to receive the threaded end of the shank 13 of the faucet. The collar 19 of this embodiment is in all respects similar to that disclosed in Figs. 1 to 4, except that in place of a fiat wall engaging face it is'provided with a semi-spherical seat or projection 27 which is adapted to form a bearing surface which will always be in contact with substantially the entire edge of the opening 11 in the wall 12 and through which the shank of the faucet exfigures, is inclosed or covered by the canopv 15.
When the collar 19 disclosed in Figs. 9
and 10 is used, the faucet shank is secured in place in the threaded projection of the T-coupling 26 and the collar 19 is rotated to bring the spherical seat or projection against the edge of the opening 11 in the wall 12 when upon continued rotation of the collar the T-coupling will be drawn against the inner surface of the wall. Should the axis of the faucet shank not extend at right angles to the outer surface of the wall the collar 19', due t its spherical seat or projection, would accommodate itself to such angular displacement and contact about the entire edge of the opening 11,
while if the collar shown in Figs. 1 to 8 'was used, the collar would contact with or touch the wall 12 at one point only, resulting in a thrust upon the threads of the shank which would ultimately cause a loose fit between the collar and the shank.
In Fig. 10 the faucet is shown asangularly displaced relative to the wall 12, and while this showing is somewhat exaggerated for illustrative purposes, it serves to show the position which the parts assume when such angular displacement takes place.
It will be noted that upon angular displacement of the faucet relative to the wall the canopy will adjust itself by body distortion, as it is constructed of a thin, bendable metal, to such angular displacement, and the canopy will contact about its entire edge against the wall and thus the collar and shank is entirely inclosed and all open spaces between the canopy and the wall in which dirt or the like may accumulate are eliminated. The collar is adapted to be adjusted longitudinally of the shank by applying pressure thereto in the proper direction, but upon applying pressure to one side of the canopy only, the canopy tends to become angularly displaced relative to the shank, and due to the anti-slipping characteristic of the packing and the extended bearing between the canopy and the shank slipping of the canopy is prevented with the result that the canopy becomes bodily distorted to adjust itself to such strains as may be placed upon it. The shank of the faucet or cock may become angularly displaced relative to the face of the wall or sink back after the parts have been assembled due to relative movement of the service pipe to the wall, or should the threads on the shank of the faucet not be turned from the true center of the cock, or should the screw threads of the T shown in Figs. 9 and 10 not be tapped straight, the shank would incline slightly at an angle to the outer surface of the 'wall 12-.
' from vibration and in place is taken from canopy will not be marred so that at all times a neat and finished fitting is had.
In present types of adjustable screw flanges, screwed upon a faucet shank, generally a sleeve projects over the screwthreaded part of the shank andthe space intervening between the faucet shank and flange sleeve becomes filled with dirt. This is unsanitary as it is impossible to clean this flange sleeve. Again, the fitting of this invention is more sanitary than ordinary fittings since the canopy has no angularlydisposed faces, about the corners of which may collect dirt and the like, but presents an uninterrupted rounded surface having no tendencies to collect dust and dirt and which may be easily cleaned.
