FIRE-HYDRANT.

SPECIFICATION forming palb of Letters Patent No. 570,031, dated October 27, 1896. Application iiled November 16, 1895. Serial No. 569,208. (No model.) i

To all whom t may concern:

Be it known that I, CHRISTIAN E. LOETZER, a citizen of the United States, residing at W'illiamsport, in the countyof Lycoming and State of Pennsylvania, have invented a new and useful Fire-Hydrant, of which the following is a specification.

This invention relates to tire-hydrants, and aims to obviate digging up or otherwise disturbing the stand-pipe in the event of it becoming necessary to make repairs of any kind or to inspect the gates and --their seats.

A further purpose of the invention is'to secure a tight joint between the gates and their seats and to utilize the water-pressure to maintain the gates in closed relation.

Other objects and advantages are contemplated and will become apparent as the nature of the invention is fully understood; and to this end the improvement consists in certain details of construction, novel features,

and peculiar combinations of the parts whichA hereinafter will be more fully illustrated, described, and specifically claimed.

In the accompanying drawings is shown an embodiment of the invention, although various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention, and in said drawings- Figure 1 is a vertical central section of a nre-hydrant constructed in accordance with this invention. Fig. 2 is a view, similar to Fig. 1, of the case or shell forming the base of the stand-pipe and inclosing the gates and the parts intimately associated therewith, showing the gates open. Fig. 3 is a plan section on the line X X of Fig. l. Fig. 4 is a top plan view of the case or shell, the housing or frame for the gates being in position. Fig. 5 is a front view of the said housing or frame. Fig. 6 is an enlarged View of the gate 19, viewed from the rear side and having the wedges in operative relation and showing the relative disposition of the parts when moving the gate upward. Fig. 7 is a view, similar to Fig. 6,0f the gate 1S, showing the relative location of the parts when applying a'downward pressure. Fig. 8 is a side elevation of the two gates and the wedges, showing the parts separated.

The same reference-numerals indicate corresponding and like parts in all the gures of the drawings, and in the latter 1 denotes the stand-pipe; 2, the dome for closing the upper endthereof and which is secured in place by bolts 3, passing through anges at their meeting parts; 4, the case or shell forming the base of the stand-pipe and inc-losing the frame or housing 5, containing the gates and their seats, and 6 the stem or rod for operating the gates when it is required to open and close the same'.

The case or shell 4 has an offstanding collar 7 at its lower end to make connection with the water-main, and its rear side is swelled or enlarged, as shown at 8, to form a waterway for the passage of the water to the stand-pipe when the gates are open.

Ribs 9 extend vertically and in parallel relation at the front side of the case 4, and their inner sides are planed or dressed to form guides for the front side of the housing or frame 5, and similar ribs lO extend vertically and in parallelism and are disposed near the rear side of the case 4, preferably at the juncture of the swelled portion 8 therewith, and the inner corners of these ribs 10 are beveled or concaved, as shown at 11, to form seats for the rear side of the said housing or frame 5, thereby centralizing and properly positioning the same when pushed home into the case 4. The ribs 9 and l0 act jointly to fix the position of the housing or frame 5 when the latter is inserted into the case 4, and the lower portion of the ribs 10 is slightly inclined toward the front side of the case, as shown at 12, toproduce a wedging action when forcing the housing or frame 5 to its place Within the case, and the lower rear portion of the said housing or frame is correspondingly inclined to coperate with the inclined portion 12 of the ribs 10 to attain the desired end. Lugs 13 are located at the entrance end of the case 4 and serve to give proper direction to the housingor frame 5 when placing the latter into the case 4., The contiguous ends of the stand-pipe and case are flanged and are secured together by bolts in the usual manner;

IOO

The housing or frame 5 isformed withreg-r Y istering openings which are supplied

ywith seats

14 and 15 and which aline with the collar 7 when the housing is in proper position. The upper end of the housing is open, and is closed by means of a cap 1G, detachably connected therewith, and which is eentrallyprovided with a stuffing-box 17, through which operates the stein or rod G. The gates 1S and 19 are adapted to move vertically in the housing 5 and are directed in their vertical movements by suitable guideways, and are formed on their inner or opposing sides with anges 2O and 21, which come together and inclose a space in which are placed the wedges, the fianges 21 having notches 20 and the iianges 2O having corresponding projections 2()b to enter and interlock with the said notches 20"L to prevent vertical displacement of the gates. A nut 2i has a wedge 22 at its lower end, which matches with a corresponding wedge 23, located below, and this nut 24 has posit-ive connection with both ot' the gates by means of lateral ribs 24, entering grooves 24h in the sides of the gateiianges, and receives the lower threaded end of the stein or rod G, so that upon rotating thelatter the

gates

18 and 10 will be raised and lowered, accordingly as it is required to open or close the hydrant. Each gate will have a packing-ring 25 to cooperate with its respective seat to secure a close and tight joint. Then lowering the gates, the lower wedge 23 will engage with a vertical projection 26 on the bottom of the housing 5, and the inclined faces of the wedges engaging and the wedges riding past one another will result in a wedging action, tending to spread the gates 1S and 19 and thereby force them close against their seats. A gasket 27, of lead or similar substance, is fitted into a recess in the front side of the housing 5 and encircles the immer end of the opening leading into the collar 7, and the purpose of this gasket 27 is to'secure a tight joint between the housing 5 and the inner side of the case 4 opposite the collar 7, so as to prevent leakage.

The stand-pipe 1 is provided at its upper end with connections 2S for the attachment therewith of the hose-pipe for conveying the water to the required point of use. These connections are norm ally closed by removable caps. A packing-plate 29 is secured between the dome 2 and the upper end of the standpipe and is formed on its top side with a stuffin g-box 30 and upon its lower side with a bearing 31, in which is fitted the enlarged end or head of the stem or rod 6. An operating-rod 32 is journaled at its ends in the dome and packingplate 29, and its lower end makes connection with the head or upper end of the stem or rod (l, so that upon turning the part 32 the stem or rod 6 will rotate therewith, thereby raising or lowering the gates, according to the direction of rotation of the part 0, as willbe readily understood. The upper end of the operating-rod 32 projects above the dome 2 and is made angular or otherwise constructed to receive a suitable instrument bymeans of which the part 32 can be rotated.

Vhen it is required to inspect the gates or repair the same, the dome 2 and the packingplate 29 are removed, and by drawing upon the stem or rod G the housing 5, with the attached parts, is withdrawn through the standpipe, and after the necessary inspection or repairs have been made the housing is replaced bypassing it down through the standpipe, and after the

parts

29 and 2 have been secured in place the hydrant is again ready for use. A pipe 33 incloses the stem or rod G and rests upon the stuffing-box 17, and its top end comes in contact with the bearing 31, and the purpose of this pipe is to secure the housing or frame 5 in place and prevent any vertical movement thereof after the parts have been properlypositioned. The pressure of the water against the gate 18 will be transmitted to the gate 19 and serve to force and hold the latter against its seat. Hence the greater the pressure 'exerted laterally against the gate 18 the iirmer will the gate 19 be forced and held against its seat.

The interlocking feature of the gates and wedges is not claimed herein, as it is incorporated and claimed in an application for a like invention tiled by me on or about July 24:, 1896, Serial No. 600,40.

Having thus described the invention, what is claimed as new is- 1. A lire-hydrant comprising a stand-pipe, a base connected with the lower end thereof and having a lateral opening, a frame fitted within the base and removable therefrom through the stand-pipe and having seats to register with the aforesaid lateral opening, means for pressing the frame laterally-against the inner side of the base, gates located within the frame and adapted to close against the seats, and actuating mechanism for opening and closing the gates, substantially as set fort-h for the purpose described.
