4 Claims. (01. sea-69),
This invention relates to improvements in pail silencers, and more especially to a novel device of this character particularly adapted for use in hospitals or the like, where silence is necessary.
The primary object or" the invention is to provide a pail silencer made of a single piece of resilient material suchas rubber, and including a cup designed to receive and grip the lower end of a pail so as to firmly adhereto the pail when the latter is carried from place to place, and to form a sound-deadening support for the pail when it is placed upon a floor surface or the like.
Another object is to furnish a resilient pail silencer adapted especially for use witha pail having a bottom flange or skirt; the silencer be ing provided with an annular groove toreceive the skirt and thus prevent accidentaltipping over of the pail.
A still further object is to provide a pail silencer having its under side which engages the floor, suitably recessed to prevent the formation of a vacuum, whereby the pail may be readily lifted with the silencer from the floor, or may be shifted along the floor. V
With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.
In the drawing,
Fig. 1 a vertical sectional view of my im proved silencer shown supporting and grasping Tthe lower portion of a pail as the latter rests on a floor surface.
Fig. 2 is a top plan view of the same. 3 is a bottom plan View. sis an elevation of theparts shown in 1, on a reduced scale. d
Referring to the drawing, fidesignates a water pail or the like which is designed to be supported and held against tipping by my improved silencer 6. The latter preferably consists of a r single piece of resilient material such as rubber, and is made up of a flat bottom 7 and an'annular wall 8. The wall is preferably of frustoconical shape, and is provided at its upper edge with an inwardly extending annular head 9 hav- 'an annular groove 14, which groove interlocks As the pail acts to expand the head when the silencer is attached, it will be obvious that the bead in tending to move back to its original contracted position, acts to firmly grip the wall of V the pail, so that even if the pail is lifted from the floor 12, the silencer will adhere to the lower end of the pail.
To accommodate a pail of the type having a flange or skirt 13 at its bottom, I provide the upper surface of the bottom of the silencer with with the flange and assists in preventing the pail from being tipped over while it is supported by the silencer. A crucial-form groove 15 is positioned in th under side of thebottom 7, so as to prevent the formation of any vacuum when the device is set upon the floor surface. This groove terminates at the outer surface of the side wall 8, and consequently, air channels extend through the bottom at all times.- These channels will allow the shifting of the silencer along the floor, or the raising of thesame from the floor without any interference by vacuum.
In'some instances, I will reinforce the wall 6 to insure a tight seal between the bead 9 and the wall of the pail. For example, the wall 6 may be provided with internal or external rubs ber ribs extending from top to bottom, or extending from the ridge down about two-thirds the height of the wall, and others extending up from the inner bottom surface two-thirds of the distance; the upwardly extending ones alternating with the downwardly extending ones Of course, such ribs will be integral with the wall 6, and may be formed thereon when the silencer is manufactured.
WhileI have disclosed what I now consider to be'ja preferred embodiment of the invention in such manner that the same may be readily understood by those skilled in the, art, I am aware that changes may be made in the details disclosed, without departing from the spirit of the invention, as expressed in the claims.
What I claim and desire to secure by Letters- Patent is:
1. A pail silencer of tub-shape,formed of a single piece of resilient material and comprising an annular wall and a flatbottom, the top of said well forming an inwardly extending annular bead of substantially cylindrical cross section adapted to grip the wall of the pail.-
2.The combination with a pail, of a cupshaped pail silencer formed of resilient material and comprising a bottom and an annular wall, said bottom having a substantially flat upper surface on which the bottom of the pail rests, the upper end of the Wall having an inwardly extending annular bead gripping the wall of the pail, said bead being held inex panded condition by the pail, and means in the under surface of the bottom for preventing the formation of a vacuum when the silencer rests on a flat supporting surface.
3. A pail silencer comprising a cup-shaped member of resilient material, comprising an annular wall and a flat bottom, the annular Wall being provided at its upper end with an inwardly extending annular bead adapted to grip the wall of a pail, said bead having an upwardly flaring surface to facilitate the guiding of a pail bottom into the silencer, and the bottom of the silencer having its under surface grooved to prevent the formation of a vacuum when the silencer rests on a floor surface.
4. The combination with a pail, of a cupshaped pail silencer formed of resilient material and comprising a bottom and an annular Wall, said bottom having a substantially fiat upper surface provided with an annular groove to receive the bottom flange of the pail, the upper end of the wall forming an inwardly extending annular head of substantially cylindrical cross section adapted to grip the wall of the pail, the wall of the silencer being spaced from the wall of the pail from the bottom of the silencerto said bead, the lower surface ofthe silencer bottom being grooved to prevent the formation of a vacuum.
