PUPFET-VALVE.

SPECIFICATION forming part of Letters Patent No. 769,382, dated September 6, 1904.

Application filed February 11, 1904. Serial No. 193,043. (No model.)

To rtZZ whmn it may concern.-

Be it known that I, HANS HOLZWARTH, a citizen of Germany, residing in Hamilton, Butler county, Ohio, (post-office address, Hamilton, Ohio,) have invented certain new and useful Improvements in Puppet-Valves, of which the following is a specification.

This invention pertaining to improvements in the construction of puppet-valves, aiming to effect their perfect balance, will be readily understood from the following description, taken in connection with the accompanying drawing, which is a vertical longitudinal section of the puppet-valve exemplifying my in vention.

In the drawing, 1 indicates the valve-body; 2, its inlet; 3, its outlet, it being understood,

however, that the outlet and inlet are interchangeable; 1, the neck-opening into the body; 5, the bonnet removably closing the neck-opening; 6, one of the valve-seats; 7, the other Valve-seat; 8, the valve-stem; 9, an enlargement of the stem where it passes through the Seats; 10, a downwardly-presenting shoulder on the enlarged portion of the stem near the. top of the valve proper; 11, the lower member of the valve disposed separably upon the enlargement of the stem and seating upon the lower valve-seat; 12, the upper member of the valve engaging the upper valve-seat, the two Valve members abutting upon each other; 13,

.a nut on the stem below the valve members and serving to hold the valve members together upon the stem; 14, the joint at which the two valve members abut upon each other; 15, a gasket between the upper valve member and the shoulder 15 on the valve-stem, and 16 a gasket (shown as of wire type) disposed between the lower valve member and the ste1nnut.

It is to be observed that the seating-lips of the two valve members are of identical equal size, the result being that the valve is perfectly balanced. A double puppet-valve in which the two valve members are of the same size cannot be withdrawn endwise through the valve-seats, and seats made removable for the purpose of permitting the removal of the valve are very undesirable by reason of the fact that in removing and replacing them there is quite apt to be a disturbance of that accuracy of distance from face to face essential to a proper seating of the two valve members. In my present construction the valve-seats if inserted as shown in the drawing are made so for the purpose of forming them of some metal more desirable than that of the valve-bod y and not for purposes of removal in removing the valve. By removing the bonnet and lifting the valve and removing nut 13 the stem may be withdrawn, after which the upper valve member may be withdrawn through the neckopening and the lower valve member removed through side opening 2. The parts are replaced by a reversed operation, and as joint 14 is an accurately-made metal-to-metal joint it follows that when the valve members are again assembled and fixed upon the stem the distance between their lips will be precisely the same as it was before the valve was dismembered. The gaskets at 15 and 16 insure against leakage through the valve members along the stem.

I claim as my invention 1. In a balanced puppet-valve, the combimoval with respect to the valve-stem of one of the valve members, a stem, two valve members disposed removably upon the stem and abutting directly against each other and having lips of equal size engaging the seats of the body, and means for securing the valve members to the stem.

2. In a balanced puppet-valve, the combination, substantially as set forth, of a valve body having a pair of circular seats and having a side opening leading from between the seats and of a size to permit the sidewisc displacement of one of the valve members, a stem having a downwardly-presenting-shoulder, an upper valve member disposed upon the stem and abutting against said shoulder and having a lip to engage one of the seats of the body, a lower valve member disposed upon the stem and abutting upon the upper valve member and having a lip equal in size with that of the upper valve member, and a nut upon the stem to clamp the valve members together and to the stem.

3. In a balanced puppet-valve, the combination, substantially as set forth, of a valvebody having a pair of circular seats and having a side opening leading from between the seats and of a size to permit the sidewise displacement of one of the valve members, a stem having a downwardly-presenting shoulder, an upper valve member disposed upon the stem and abutting against said shoulder and having a lip to engage one of the seats of the body, a lower valve member dispose upon the stem and abutting upon the upper valve member and having a lip equal in size with that of the upper valve member, a gasket in position to prevent leakage through the valve members along the stem, and a nut seer AVAILABLECQPT and abutting upon each other and having lips of equal size engaging the seats, and a nut upon the enlarged stem for clamping the valve members together and to the stem.
