Moronimms VALVE.
Patented April 27, 1909.
' Application filed January 2, 190a. Serial No. 408,912.
' To all whom it may concern:
I 3e it known that I, BENJn1\lINlJE WIS, a citlzen of the United States, residing at Schenectady, in the county of Schenectady,- State of- New York, have invented certain -new and useful Improvements in Motorrnens Valves, of which the following is a specification. I
invention relates to motorm ens valves,
and its object is to produce a valve of novel design, which is cheaper in construction and more serviceable in. operation than the valves now generally in use.
-- My invention relates to the connection be tween the valve and its operating spindle.-
.The s indle shouldb' readily detachable fromlt e valve, but the connection between them should be such that they can be locked together in one relative position only.
One'form of connection, which has beenused commonly heretofore, consists of a transverse groove on the valve having its sides at an angle to each other, and a proectlon on thespindle tapering in a trans-' verse direction, so that it can fit in the groove onthe valve in one position only relative to the valve. serves its pur ose, but is expensive to make, since each si e of'the groove and each side of the projection must be machined separately.
My invention consists in forming the Y groove with parallel sides, but deeper at one end thanat the other, and making the projection which enters the roove of a length greater than the depth of the groove "at its shallower end, so that the projection can fit intothe groove in one position only of the spindle re ative to the valve.
.My invention will best be understood by drawing, in
In the drawings, A represents the valve body, the upper portion of which forms a valve seat provided with ports; B represents p a valve rotatable on the seat; 0 is the spindle for operating the valve; D is the bonnet inthe spindle. other so as to forma transverse groove with Such a construction -dle relative to Silll ,closiiig the valve. and s indle; and E is the operating handle detac iably engaging the upper end of the spindle C, The connection between the valve and spindle is formed by means of the-walls b-on. the valve and the projections c con the enlarged lower-end of The walls I) are parallel to each parallelsides on the upper side of the-valve; ut the de ths of the groove at its opposite ends. are ifi'erent. The two projections c andc, which enter the groove are of different lengths, the longer projection 0 having a lengthrgreater than the depth at the shallower end of-th'e groove. .It will be 'seen that with this construction, the projections on the spindle can fit into the groove in one position only of the spindle relative to the valve. It will further beseen that both sides oi the groove can be machined at a single operation.
Between the bonnet D and the enlar ed lower end of the spindle C is placed a was er F, which fits loosely around the spindle and has convex bearing surfaces. on both-"its upper and lower sides, while both the bonnet and the lower end of the spindle have concave bearing-surfaces. With this construction a slight ti ping of the spindle C, such as might be pro need if the motornian should press down upon the operating handle, will not produce a separation between the washer F and either the bonnet or the spindle; but sincethe washer F-fits loosely around the spindle, a slight movement of the spindle will be taken up by the slight sliding movement between. the washer l! andthe spindle or bonnet, or both. a
W'hat I claim as new and desire to secure by Letters Patent of the United States, is,-
1. Ina motormans valve, a valve seat having ports, a valve movable thereon, and a spindle for operating said valve, said valve and spindle being provided the one with a transverse groove with parallel sides and the other with a projection adapted to fit into said groove in one losition only of the spinl valve and to lock said valve and spindle together in said relative position. v
2. In a inotornmns valve, a valve seat having ports, a valve movable thereon, and a )indlc foroperating said valve, said valve on; spindle being provided the one with a transverse groove with parallel sides but of difierent depths at its op osite ends, and the other with projections adapted to enter said other with a projection a apted to enter said groove and to lock the valve and spindle o groove but of a length greater than the together, said groove being deeper at one end 15 depth of the groove at its shallower end, than at the other and one projection being whereby said projection fits into said groove longer than the other.
in one position only of the valve relative to 1 In Witness whereof, I have hereunto set the s indle. 1 l my hand this 30th day of December, 1907.
