Specica'tion of Letters Patent. I

Patented Feb. ze, 1916.

Application filed August 30, 1915. Serial No. 48,049.

To all 'whom t may concern.'

Be it known that I, DAVID J. HUNTER, a citizen of the United States, residing at Saegertown, in the county of. Crawford,

State of Pennsylvania, have invented a new and useful Ventilator for Toilet Bowls or Hoppers; and I do hereby ldeclare the following to be a full, clear, and exact description of the invention, such 4as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved ventilator for toilet bowls or hoppers, and

an object of the invention is to ventilate the bowl and the space immediately above the bowl, and to provide hollow hinge connections with the cover and bowl, there being means afforded connected to the hollow hinge connections, for carrying oil'l the odor- 20 ous gases to the atmosphere. The means.

for carrying oil' .the gases also having connections'with and above the waste pipe to further assist in carrying oil" the gases.

One of the features of the invention is -to provide the hollow hinge connections wi h means to `prevent lateral movement of thev seat and thecover of the bowl or hop- 3'0 tion may necessitate alterations falling within the scope of what is claimed.

'The invention comprises further features and combination of parts, as hereinafter set forth showing the drawings, and claimed.

In the, drawings :--F igure 1 is a View in perspective of the improved Ventilating system and the hinge connection, as applied to a toilet bowl or hopper. Fig. 2 is a sectional view on line 2-2 of Fig. 1.

Fig. 3 is a sectional view through a portion of the hopper and the seat and cover, showing a part of the ventilator. Fig. 4 is a plan view of the hopper or'bowl, showing the hinge connection (which is hollow for carrying oft'v the odorous gases) between the f hopper or bowl and the seat and cover. Fig. 5 is a transverse sectional view on line 5-5 of Fig. 2. Fig. 6 is a sectional view on line 6-'6 of Fig. 4.

Referring more especially to the drawings 1 designates the usual form of toilet bowls or hoppers, which is provided with a waste pipe 2 having an off-set pipe 3, which merges into a vent pipe 4. The rear of the hopper or bowl near its upper portion is formed with an extension 5,' through which the flush pipe 6 from the Hush box 7, connects. The rear part of the bowl or hopper adjacent its upper edge and above the extension 5 is formed with a transverse flange or extension 8. This extension 8 extends partially upward as shown at 9, and 1s curved transversely, as shown to form a seat 10, for the transverse pipe 11. Screws 12` are threaded upwardly through the extension 8 and into the pipe 11, to secure the same 1n place. One end of the pipe 11 has a cover .or cap 13 threaded thereto, the other end of the pipe 11 is threaded into a sleeve 14, which in turnis threaded to the pipe 15, which connects or communicates w1th the vent pipe 4. This ,vent pipe may extend up through the wall of the house` and terminate above the roof, or'it may extend up through the room adjacent one wall thereof and pass through the ceiling and terminate above the roof. The rcar vedge of the seat of the hopper is curved transversely as shown at'16, to receive and v engage the circumference of the pipe 11.

'Ihe seat 17 is provided with the usual opening the wall of which is channeled or grooved as shown at 18, and the under face of the seat is formed with a groove 19. Fitting the grooves 18l and 19 and being arranged adjacent the under ,face of the seat is an aluminum plate 20, the part 21 of which Vconstitutes an entire wear plate. The portions 22 of the wood seat overlie the extended ange 23 of the plate 20, so as to .prevent the plate 20 from contacting with the persons body. The entire wear portion of the plate 20 is grooved or concaved as shown at 24, to receive the upper edge of the wall of the hopper or bowl. The plate 20 terminates as Shown at 25 on the outer yedge of the seat, thereby vpreventing the plate 20 from contacting with the persons body. A U-shaped plate 26 arches the pipe 11, and has its upper portion secured at 27 and 28 to the upper face of the Vseat near its rear. part. The under part 29 of the plate 26 is secured by screws 30 to the rear flange 31 of the rear part of the plate 20, so that the seat will swing hingedly on the pipe 11. It will be noted that the plate 26 adjacent its arch, that is, where it arches over the pipe 11, is formed with an opening 32 so as to permit the upwardly extending part 9 to protrude through the opening and engage the pipe 11. It is to be observed that the opening 32 or cutaway portion corresponds in width to the length of the part 9, so that the portions 330i the plate 26 willabut or engage the i opposite ends of the part 9, thereby prewhen the seat isclosed or lowered, so that` will'be carriedoo through 38 andl 39, and

seat in lits open position.

venting lateral movement of the seat. rllhe edge 34; of the opening 32, when the seat is thrown open engages the rear face of the part 9 as shown at 3 5, thereby limiting the sure'36 for theseat has its-hinges (37, also secured at 28, so that the cover may be raised independently ofthe seat or raised with the seat when the seat is raised. The rearwall of the seat has an elongatedopening 38' corresponding in length and registering with the opening 39 in the pipell,

the odorous gases from the hopper or bowl through the pipe 1'1, and thence outwardly through the vent pipe 4 to the atniosphere. I'Ihe escape of the odorous gases is accom ,'plished, while the hopper or bowl is in use. However, whenthe cover is`closed, any remaining vgases will pass off through the vent p1pe in a similar manner, and yet the pipe 11, with the plate .26 constitutes hinge connections between the seat and thhopper.

The invention having beenset forth,`what is claimed as new and useful is: 1. In combination with a hopper having a flange at its rear adjacent the upper part, said flange having anupwardly extending portion, a pipe secured'to said upwardly extending portion constituting a hinge part and vhaving one end closed, and its other end conn'ected to a vent plpe, a hopper seat ',havmg a groove in itsY rear edge to annular-ly and slidahly engagesid pipe, a U-shaped plate arching the pipe and having its upper and lower portions secured'to the seat',.there by hingedly connecting the seat to the pipe,

- said U-shaped/` plate having an opening adjacent its arch part, through which said opening the upwardly extending part of the iange extends, to prevent lateral movement ofthe seat, said pipe having anopening in its Wall adjacent the edgeof the seat, the

rear part of the seat having an opening in its wall registering with the opening in the pipe, to carry ofi the odorous gases through the pipe. A

2. In combination with a hopper having" a flange at its rear adjacent the upper part, said iange having an upwardly extending portion, a pipe secured to said upwardly extending portion, constituting a hinge part and having one end closed, and its otherend 'connected to a vent pipe, a hopper seat having a groove in its rear edge to annularly and slidably engage said pipe,l a lU- shaped plate arching the pipe and'having` its upper and lower portions secured to the opening in the pipe, to'carry ofthe odorous gases through the pipe, one edge of the i opening in said U-shaped plate constituting an abutmentv to contact with the up-standing portion 'of the lange to limit the seat in its open position.

In testimony whereof I'have signed. my name to this specification in the presence of two subscribing witnesses.
