' HANDLE Filed Dec. 30, 1932 2 Sheets-Sheet 2 @IQQA Patented July 14, 1936 UNlTEos A-TEs PATENT OFFICE} HANDLE 3 Jacob Podolsky, Dorchester, Mass.

-' Application December 30, 1932, Serial No. 649,538 "16' Claims. ((31. 287-53) The present invention relates 'to handles and the like adapted to befixed to a valve or other stems; w r

According to present-day practice, 'the valve handle is fixed "to the valve'stem in the factory, and the parts are thensold' as a unit in the trade. When the handle becomes broken, it becomes necessary either to find a new handle to match the stem, or else todiscard both elements and purchase a new combination of handle and stem. The first alternative isattended with difficulties because, the parts not being completely standardized, no one handle that-is available in the stores will fit-all valvesterns; so that it becomes necessary 'tokeep in stock a very large assort ment of'shapes andsizes; Evenwhenthe proper shape and size happens to be in stock, furthermore, it frequently happensthat it will not fit the valve stem because of wearing down'of the parts. These'condalternative, therefore, is more often resorted to. "It is,-furtherni0re, frequently desirable to remove the handle from the stem, so as to prevent unauthorized turning of the latter, and this, too, is'not convenient with most present day constructions. V

d An objectof the present invention, therefore, is to provide a new, and improved device for attachment to a stem.

A further object is to provide anew and improved device for turning valve and other stems.

It has heretofore been proposed to provide a single handle that shall be readily adapted to theturning of a large number'of' different valve or other stems. Among: the; proposals of this character has been the use of a screw or'screws for fastening the, handle to (the stem. Continued use of such a device, however, tends to cause the screws to wear grooves in the stem, thus endowing the handle with a certain degree of objectionable lostmotion. j h

It is therefore another object of the present invention to provide a noveldevice of the abovedescribed character that shall be absolutely certain in operation, and efficient, and without lost motion.

Still another'objectjisi to providean improved construction permitting" the eflicient us'e'of any of a large number of standardized'handlesfand the like with a single stem; or, conversely, any of a large number'of stems with a single handle and the like.v Y

O er and further. objectswilllbe explained hereinafter and will be particularly pointe'd out inthe a pended claims;itbeing understood that it is intendedfby' suitable expressioifin' the claims, to express all the novelty that the invention may possess.

The invention will now be explained in connection with the accompanying drawings, in which Fig. 1 is an elevation of a valve handle embodying the present invention; Fig. 2 is a vertical section taken upon the line 2-2 of Fig. 1, looking in the direction of the arrows; Fig. 3 is an underside perspective, showing the parts separated, for clearness; Figs. 4 to 6 are perspectives of modifications; Fig. 7 is an elevation, partly in longitudinal section, of a further modification; Fig. 8 is a section, similar to Fig. 2, of further modification; Fig. 9 is a section of a further modification; Fig. 10 is a perspective of the 5 Fig. 12 is an elevation, partly in section, as in Fig. '7, of still another modification; and Fig. 13 is arperspective of a detail.

Referring first to Fig. l, a rotary stem 2 is 20 shown provided with a handle 4 for turning the same. This handle may be of the crosier, allmetal form shown in Figs. 1, 2, 3, 5 and 8 to 10, or it may take any other form, such as the levershaped handles 5 or I of Figs. 6, 7 and 11. It may take other forms than handles, and a soap dish 6 is shown in Fig. 12, though the stem 3 on which it is'mounted is not rotary, but is fixed. The stem 2 or 3 is ordinarily provided with a polygonal or cubical top 8 adapted to be received in a correspondingly shaped socket or opening provided upon the underside of the handle 4, as shown at ID in Fig. 10. It is necessary, therefore, to keep in stock as many different handles, 3

with correspondingly shaped sockets l0, as the stems 2 are provided with tops 8.

According ,to the present invention, however, a single handle 4, 5 or I, or a single other article,

such as the soap dish 6, may be utilized in con- 40 nection with all stems 2 or 3 in use. It is thus possible to replace lost or broken handles, whether of metal, china or other materials, in all cases, and using all stems 2 or 3. To bring about this result, a polygonal member II is shown in 45 Fig. 13, having a portion 12 shaped to correspond to the polygon I0, and provided with a cylindrical, polygonal or other conventionally shaped socket I4 within which may be received the top 8 of the stem 2. The member ll may be cubical 50 in shape, but it is preferred, for appearance sake, to have the portion l3 below the portion [2 externallycylindrical. Set screws 16 may be threaded through corresponding-threaded openings 18 in the cylindrical walls of the member 55 I2, and into and against the top 8 of the stem. The top 8 is thus received in the socket I4 and becomes fixed to the member I2 by the set screw or set screws I6.

The member I I being of the same polygonal or cubical shape as the socket II] in the handle 4 and as the opening I4 may be so designed as to receive a very large number of different sizes and shapes of stem 2, the combination of a single member I I and a single handle 4 may thus cooperate with a very large number of different sizes and shapes of stem tops 8. Indeed, the member II and the stem may be regarded as, in effect, a single stem having a constant size and shape of top 8 for cooperating with but a single corresponding size and shape of socket II in the handle 4. e

The handle may be secured against accidental displacement from the member II by means of a collar 26 loosely mounted upon the stem and having external threads 22 for cooperating with internal threads .23 provided upon a down-hanging sleeve 25 of the handle. In this manner, the polygonal exterior member II is detachably held fixed in position in the polygonal interior socket I without accidental displacement, the parts cooperating to permit turning of the stem 2 by the handle 4.

A construction of this character is very satisfactory in the case of non-rotatable stems, such as the stem 3 of Fig. 12 for supporting the soap dish 6, the parts being held together very firmly by the screws I6. When a rotary stem 2 is employed, however, continued rotation of the handle 4, 5 or I causes the screws I6 to dig circular grooves or scores in the stem 2, even though the 1 screws be provided with sharp-pointed ends II.

According to the preferred embodiment of the present invention, therefore,particularly for use with handles 4 or 5 for turning rotary valve stems 2, the stem 2 is turned directly from the handle 4 or 5, and not indirectly, through the medium by means of a separate rod 28, fixed in holes 30 in the side of the handle 5, illustrated in Fig. 6. It .does not require any very great degree of accuracy in filing the slot 24 to prevent relative rotatable turning movement of the handle 4 or 5 and the stem when the stem 2 is received in the handle 4 or 5 and the tongue 26 or 28 is positioned in the slot 24.

There would, however, be danger of the tongue 26 or 28 slipping out of the slot 24 in a direction longitudinal of the stem 2, in response to turning movement of the handle 4 or 5. This is pre-, vented by the collar 20 engaging against the lower. end 32 of a spacer member 34, the upper end 36 of which engages against the bottom face of the socket I0.

Screws I 6 are screwed through the walls of the spacer member 34, in the same way as through the walls of the member I I, and into engagement with the stem 2. These adjustably' threaded screws I6, at a plurality of points along the circumference of the spacer 34 do not, however, hold against the stem 2 to effect turning movement. Their function, rather, is merely to adjust the stem transversely in the socket 35 of the spacermember 34, thus to center the stem 2 in the spacer member 34 relative to the stem 2 that is fixedly received in the socket 35. The spacer 34, in turn, is itself centered relative to the handle 4 by having its upper end 36 positioned in the socket II), which thus acts as a centering socket. To effect this result, the upper end 36 might be made square shaped, the same as the part I2 of the member I I, and of the same square dimension as the socket I0, thereby helping to prevent relative, rotatable movement of the handle and the stem. That such help is not really necessary, however, is demonstrated by the fact that the socket may be circular and of the same diameter as the spacer 34, as illustrated at 31 in Fig. 5. It is preferred to make the end 36 round, but of substantially the same diameter as the length of the side of the said square. The bottom 32 may be square shaped, as illustrated in Fig. 3, cylindrical or round, as shown in Fig. 4, or any other desired shape.

By having the socket 35 wide enough, it is possible to accommodate all sizes and types of stems 2 or 3, whether rotary or stationary, straight or crooked, and for all kinds of valves, including steam, radiator and bath, as well as faucet, valves, and whether made of metal or any other material, and irrespective of the height of the valve stem. The parts hold rigidly together, without lost motion, just as efiectively as was the case with the original handle.

The upper portion 36 may be widely slotted at 38 so as to provide plenty of room for the tongue 26 or 28 to extend 'therethrough without, preferably, engaging against the sides of the slot 38. In this way, it is assured that the turning movement of the handle 4 or 5 will not be communicated to the spacer member 34. If desired, however, the slot 38may. be made just wide enough to receive the tongue'26 or. 28 snugly. On the other hand, the area at the top end 36 may be made smaller still, and it may consist of several upwardprojecting pins.

With this construction, it is not always essential that the socket Ill be employed, and it may be omitted, as illustrated in Figs. 6 and 7, when the central opening 46 in the. collar 20 is not so great as to cause the stem 2jto become positioned off center with respect'to the handle 4 or 5.

The lower end 32 of; the spacer member 34 acts as a stop, controlling the degree of tightening of the collar 20. 'It isnot necessary, however, that the collar 20 engage 'the lower end 32 of the spacer member 34, for it may. be spaced therefrom, as illustrated at 42in Fig. 8, without interfering with the cooperation of the handle 4' or 5 and the spacer member 34 to prevent substantial relative movement of. thehandle 4 or 5'and the stem 2 or the spacer 35, in a direction longitudinal of the stem. 'The square'shape. gives greater body to the spacer member and'helps, in some cases, to centerthe device by engaging against the inside wall of the collar 20 or the down-hanging sleeve 25 of the handle 4, on which the threads 23 are formed.

'The modification illustrated in Fig. 11 has to do with, a typeof handle in common use, comprising a metal portion 44 having. an opening46 in which thetop 8ofthestem 2 is received, and in which it is held by a, screw against a flange 50. The metal portion 44, is provided with a stem 52 over which a china, porcelain or other frangible handle (not shown) ismounted. Whenthis frangible handle becomes broken, the whole device is requiredto be discarded or thrown away.

According to thepresent invention, however, an

enemasnmate sleeve '54 is mounted over the stem 52,'and is held in position thereon by one or more screws 5E A-plurality of screws 56 is preferabIe becauSehelping to center the'sleeve 54 on the stem 52, though the centering difficulties are notserious. I An internally-threaded metal or other handle 1 is then' threaded onthe externallythreaded sleeve 54, into contact with a circular, peripheralflange plate-'51 of the sleeve 54. The new device ispermanent, thus being a great improvement uponthe old, frangible handle (not shown) but a new handle I may always be threadedupon the sleeve 54 in substitution for the old when desired.

The invention oiiers a very convenient, satisfactory and inexpensive replacement of broken or lost handles. for stems, necessitating the keeping by the dealer of but a minimum of stock. No cement or other adhesive is required. In all cases, furthermore, the screws 16, the slot 24 and other unsightly parts are hidden from view, thus greatly imp-roving the appearance of the device.

Further modifications will occur to persons skilled in the art md all'such are considered to fall within the spirit and scope of the invention as defined in the appended claims.
