OF MANSFIELD, OHIO, A CORPORATION OF NEW JERSEY VALVE AND METHOD or MANUFACTURING SAME Application ledV Ju1y'26, 1927. Serial No. 208,575.

My invention relates to valves and particularly to the closing portion and the method of manufacturing the same.

The object of my invention is to produce Tf1 a valve which is simple, economical, of few parts and free from the defects which most valves now on the market are subject to.

My invention resides in the new andnovel construction and relation of the various parts )su hereinafter described and shown in the drawing and steps necessary to produce the same.

In the drawing Fig. l shows the first step in the manufacture of the closing portion which I will hereinafter term the valve member.

Fig. 2 shows the second step in the manufacture of my improved valve member.

In the construction and manufacture of my improved valve member the same is formed P up out of sheet metal, preferably'brass, as this metal is uniform in thickness, uniform in quality and can be secured at a veryreasonable price to any thickness desired and to any width, and, therefore, lends itself very read-V ily to the economical production of a valve member.

By properly designing the valve member very little waste material is necessary and this point I have particularly had in mind in designing my improved valve member.

I have alsohad in mind reducing the number of operations asfar as possible, thereby assisting in another way to reduce the cost without sacrificing the essential points necessary in a valve member of this character.

In constructing thevalve member I employ a' strip'of sheet brass indicated by 1 in Fig. 1 and probably of the exact. width required without waste. The first operation is to Acut the notch 2 in the valvemember and simultaneously therewith the horse shoe shaped slot 3 and the hole 4 which acts as a bleeder hole in the completed article. The only metal wasted in the production of my valve member is that in the

cuttinvaway portions

2, 3 and 4 in the first operation and the punching of the stem hole 5 in the fifth operation.

` From this, it will be readily seen there is very little waste of material in the forming up of my improved valve member.

In lthe second operation shown in Fig. 2 the end portion of the strip 1 is cut along the dotted line 6 and simultaneously therewith is produced the cut away

portions

2, 3l and 4 of a second valve member and the second steps shown in Fig. 2 separate the stamped portion shown in Fig. l from the sheet 1 and simultaneously with the operation described in connection with Fig. 2 the tongue or head 7 is formed up at right angles with the plane of the strip or sheet.

i rllhe third operation on the sheet or strip l repeats that described in Fig. 2 by separatingthe portion 8'from the strip along the line 6, bending the head 7 up at right angles and producing slots corresponding to 2, 3 and 4 for the third valve member, as previously described.4

vThe bending up of the head 7 produces an enlarged 'opening 9 completely surrounded with metal'which acts as a passage for the fluids through the valve when the valve is fully opened.

y In the third operation a portion of the body 10 is bent into a semi-circular form, as shown in Fig. 5, and in reasonably close relation to the head 7, as shown in Figs. 5 and 6.'

In the fourth operation the unformed p0rtion of the body 10 is lbent round so as to complete the formation of a cylinder in close relation to the head 7 and with a slot 11 between the adjacent edges 11 and 11".

In the iifth operation the hole 5 is cut in the head to receive the lower end 12 of the valve stem 13. The hole 5 and the end of the stem 12 are other than circular, but of corresponding shape so that the two when secured together will rotate in unison.

It will be observed `that in the completed valve member the bleed hole 4 '-is'opp'osite the main opening 9 so that when the valve is in its closed position, the 'bleed hdl`e`4`wi'll permit a slight circulation ot therluid in the system.

The head 7 is formed up out ofthe metal which once occupied the spaceottheopening 9 and issecured to the body 10 'by' `means of the neck 14.

The valve body is rnot particularly unique in' any respect, but comprises a: cylindrical portion 15 which is machined to a'substantially smooth cylindrical-surface inside provided withropenings 16 and 17 to which pipe connections are secured. The body 15 is provided `with 1an end 4portion 18 fupon lwhich is mounted a threaded gland 19 and which with thepackingnut'() secured thereto comprises a packing chamber in which is Epositioned packing material 21 which prevents leakage around the stein 13;

To the upper end of the stem 13 maybe secured the usual. type of handle, either of the round wheel shape or the lever shape 'or any other suitable form.

It will be noted that the cylindrical body iortion 10 at onev end lis vprofvided with a raised 'or stepped portion 22 land theedgesfof this portion form abutments which-engage with a stationary stop 23 secured-to the inner face of the end 18. The engagementofL the edges ofthe steppedportion `22 with rthestop 23 limits the opening and closing `movement of the valvemem'ber. the inward bending of the head V17 should one stand upon the upper end of the valve stem 13 or the handle thereon, I have vprovided a-vshoulder 24 onthe stem which engages with acorrespondingLshoul'der on the end `of the body Iand this will support any weight which may be applied'to `the upper end of the stem and will prevent an inward'movement of the stem. The inner en'd v120i1 the stem passes through the opening 5 in the head ofthe 'valve membervand is headed over at 25, and this then prevents removal of the valve member with .respectt'o'the stem and with the shoulder on the stem lengaging the valve body it is impossible to raise or lower the valve stem more than an amount equal to the clearances `between the valve-member and the body and all vertical movement can be eliminated if desi-red.

Also. the construction'thus Vdescribed prevents the removal of the valve member from In order to preventthe body only when actually necessary, which in the type of valve shown is very seldom, it ever, necessary.

It will be observed that the valve member forms practically a complete cylindrical sleeve `excepting for the main opening 9 and what space y11 there may be between the adj acent edges of the valve member, and this in sures a bearing surface between the valve member-ofthe valve bodyover a larger area, and 'this is bound to give a much smoother opera-tion of the valve member when the valve is openedand closed.

The slight opening .11 in the valve member permits a yielding or spring action between the valve member andthe body, thereby insuring-the valve.member to tit `the inner suri'acc of the valve body sulliciently close to limit leakage past the valve member, when closed, to a negligible quantity as the valve is usually used on what is known as hot water heating systems where the pressure is very low and the probabilities are that the leakage through the bleedhole 4 will be greater than any leakage between 'the valve member and the body.

The hole can be made in the head 7 in the first operation (Fig. 1). The head 7 is connected to the sleeve portion 10 bv the neck 14 which isremote from either transverse end ofthe valve member or `intermediate the transverse ends and, therefore, Ithere is less tortional strain set u p in the valve member whenit is rotated than if the neck were at theIeXtreme-end, and ythe ,nearer the head is connected to the center of the length otrthe sleeve then the less the tortional strain becomes.

It is .believed from ythe disclosure4 herein made that one will appreciate that I have provideda val-ve in which the valve member is of a decidedly vunique construction, and produced witlra. minimum amount `of operations and with the use of a minimum amount of metal in the discand1 a minimum amount ot loss or waste' of metal inthe forming` up oi the valve member.

There will, of course` be modifications which will. suggest themselves-.to those skilled in the art., but I wish to be limited only by mv claims.
