CHECK-VALVE.
y Specification of Letters Patent.
Qgiginal application led April 19, 1907, Serial No. 369,055. Divided and this application led February 18, 1908. Serial No. 416,457.
with systems of steam heating such as is describe in an application for Letters Patent serially numbered #369,055 and of which the present case is a divisional application;
and the principal object of the present invention may be said to be to provide a check valve for radiators to ermit of the circulation of steam in one irection onlyv and to permit air and water of condensation to readil escape from the radiators.
A fiirther object is to apply to what is usually termed a steam fitters union, the valve of the invention without in any way altering the construction of said union. y
A still further ob'ect is to rovide a union ap or va ve disk which the angle of the union.
Other objects will appear hereinafter.
The invention stated in general terms comprises the improvements to be presently described and iinall claimed.
The nature, c aracteristic features and sco e of the invention will be more fully un erstood from the following -description taken in connection with the accompanying drawings forming part hereof and in which:-
Figure 1, is an elevational View of a radiator havinglapplied thereto a check valve embodying t e invention. Fig. 2, is a view in central section of the valve part-s embod ing the invention and illustrating the same a out to be' assembled. Fig. 3, is a view in central section of the valve parts assembled. Fig. 4,
is a view in cross section of Fig. 3. Fig. 5, is a view in central section of a somewhat modified form of the invention; and Fig. 6 is a similar view of a still further modified form of the invention.
In the drawings there is shown a radiator 1, to which is connected a steam supply pipe 2, and a return pipe 3. In the return pipe 3, arranged in juxtaposition to the radiator, is
l-a check valve 4. This check valve permits of a free circulation of steam through the radiator in one direction only and at the same time readily permits of air and water of condensation leaving the radiator. Referring more especially to Figs. 2, 3 and 4, the check valve 1s shown to comprise what is known as a steam litters union consisting of inlet and outlet branches 5 and 6, interposed between the beveled portions of which is a enerally dish-shaped, comparatively shal-` said branches being securely held to place by means of a coupling or Spanner-nut 8. The inlet branch 5, is shown -as being in one piece, the inner end of which is considerably enlarged at 9, and is ofthe configuration of a frustum of a cone terminating in a shoulder 10. The outer end of the branch 6, is screw threaded for application to the outlet end of the radiator. The outlet branch 6, is arranged at an angle to the inlet branch and isexternally threaded as at 11, for a purpose to be described and is internally threaded as at 12, for application to the return pipe. The
wall of the inner portion of the branch 6, is
increased in thickness as shown in order to provide a beveled seat 13. The coupling or Spanner-nut 8, is internally threaded as at 14, and is adapted to engage the threaded portion 11, of the branch 6, and its outer portion is provided with a ange 15, which is ada ted to abut against the shoulder 10, of the ranch 5, the opening 16, of the nut 8, passing over the enlarged part 17, of the said branch. The generally dish-shaped member 7, is shown as being of comparatively thin metal the walls of which are aslant and is provided in its bottom wall with a central opening 18, above which are lugs 19,' having pivotal relation with which is a` valve-disk 19, which may be weighted as at 2'0. When the parts are assembled, this dish-shaped member 7, is arranged between the two branches so that the part 9, of the inner branch fits within the dish-shaped member 7, and the beveled seat 13, of the branch 6, fits over the dish-shaped member, or in other words are nested one with respect to the other as clearly illustrated on Fig. 3, and may be readily adjusted within the union by merely loosening the nut 8, so that the valve-disk may be shifted toalways assume a vertical position irrespective of the various angles in which the union may be placed.
ow, member 7, carrying a valve disk, the.
In Fig. 5, the inlet and outlet branches are shown in alinement andthe part 21. of the inlet branch is curved convexly, and the part 22, of the outlet branch is curved concavely,
vand the dish-shaped member is convexly-eoncavely curved to fit between these parts. The valve disk 23, thereof is provided with a stem 24, which loosely fits within an opening in the arxn 25, pivotally hinged from lugs 26, arranged above the opening in the dishshaped member. 4The stem is screw threaded for the reception of a nut. Q7, to confine the vdisk to the arm.
In Fig. 6, instead of a hinged flap, the dish-shaped member is equipped with a valve-disk 28, having a stem 29, that Works through a bearing in the spider 30, otherwise theconstruction is the same as described in Fig. 5.
It will be readily seen by reference to' the drawing that the valves open in 'a direction away from the taper or slant of the side l walls of the dish-shaped members.
IVhat we claim is A check valve comprising a union consisting of a pair of members having their meeting faces inwardly and outwardly beveled to seat each other, a generally dish-shaped member having a vertical valve opening in its bottom wall and a valve therefor adapted to open ina direction away from the taper of said dish-shaped member, said member being positioned between the beveled parts of the union and a nut for coupling the union parts together.
In testimony whereof we vhave hereunto signed our names.
