CONTROLLER HANDLE.

Application fi1ed March 18, 1925.

T0 aZZ wh0m z't mug concern.

Be it known that I, WILLIAM Bnown, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, hare invented certain new and useful Improvements in Controller Handles, of Which the following is a specification.

This invention relates to improvements in controller handles of the type adapted tobe applied to the stem of the controller of an electric railway car forthe purpose of operating the controller, and one of the objects of the present invention is to provide a handle which may be readily applied to the controller stem and, when properly applied, Will be. securely held upon the stem and adapted to be operated to rotate the stem without any lost play, such as is often present in the use of ordinary controller handles. lVhile I am aware that controller handles have previ ously* been designed and constructed to adapt them to be clamped to the controller stems to which they are applied, nevertheless, such handles have consisted of two hinged sections and as a result the han les are incapable of withstanding the rough usage to which they are subjected. It is a well known fact that such handles are frequently carelessly and roughly handled by motormen not only when they are in place upon the controller stems, but also after they have been removed from the stems, so that the handle which comprises several pivoted or hinged parts does not possess suflicient strength and durability to render it desir able for use. Therefore, it is another important object of the present inxention to provide an integral or one-piece controller handle possessing great strength and durability and, at the same time, embodying means to adapt it to be firmly clamped upon a controller stem.

In controller handles of the type comprising two pivotally or hingedly connected sections, a set screw or clamping screw is ordinarily provided for drawing the sections together to clamp them at their ends about the controller stem and it is quite obvious that in such a construction the clamping screw is subjected to considerable strain because, when the handle is swung, the tendency is for the ends of the sections thereof to be spread apart through the resistance oflered by the controller stem, its

end beingof rectangular form and fitted be tween said encls of the handle sections. Therefore, the present invention has as a further important object, to so construct the handle that the clamping screw or bolt employed in connection therewith will be subjected to minimum strain.

In the accompanying clrawings:

Figure 1 is a view in side elevation of the controller handle embodying the invention mounted upon an electric railway car controller.

Figure 2 is a plan view of the handle, the controller stem being shown in horizontal section.

Figure 3 is a vertical transverse sectional view taken substantially on the line 3-3 of Figure 1, looking in the direotion indicated by the arrows.

The handle embodying the invention comprises a shank portion indicated by the nu- 1neral 1 and an upwardly curved arm 2 Which extends fromone end of the shank portion. The handle is of substantially uniform width throughout its entire length and the body of the handle is preferably formed from a single metal blank. At its end opposite its encl trom which the arm 2 extends, the shank is preferably rounoled as at 3, at its exterior surface, and is formed with a rectangular socket indioated by the numeral 4, of dimensions to adapt this end of the shank to be fitted to the stem 5 of the controller 6. Said shank 1 and the arm 2 are formed with a slot 7 whioh extends longitudinally thereof and at one end opens into the socket 4 and at its other end terminates short of the free end of the arm 2. Ordinarily, the handles Will be made of brass, which metal possesses a degree of resiliency suitable for the purposes of the present invention, and the socket 4 Will be of such dimensions as to adapt it to be initially reely fitted onto the stem 5 of the controller. The shank 1 of the handle is preferably formed in its opposite sides with recesses 8 and, at its end from which the arm 2 extends, the said shank is formed with alined transverse openings 9. A clamping bolt 10 is fitted through the openings 9 and has its shank threaded into a nut 11 Which is seated in a shallow recess 12 formed in the wall of the corresponding recess 8, the other end of the shank of the clamping bolt being provided with a winged head 18 adapting the bolt to be readily tightened by hand, the base of the head seating within the other recess 8, as clearly shown in Figures 1 and 3 of the drawings.

From the foregoing, it will be evident tlmt while the socket 4 is so prportioned that it Will initially reely acco1n1nodate the s tud 5, when the l1andle is fitted to the stud and the bolt 10 is tightened, the opposite walls of the slot 7 Will be brought together and the socket 4: Will tl1ns be sutliciently contracted to cause its Walls to fir1nly frictionally bind the controller stem In this 1nanner the h andle is securely und yet readily removably fixed upon the controller stem and may be operated to rotate the stem without any play or lost 1notion. Furthermore, there is no likelihood of the lmndle becoming accidentally disengaged from the stem.

At its outer end, the arm 2 supports a hand grip ll which may be grasped, as HSL1E Ll for the purpose of swinging the handle.

It Will be understood that inasmuch as the handle is 0 integral construction as distinguished fron1 comprising two pivotallyor hingedly connected sections, minimum strain is impos ed upon the clamping bolt 10. Furthermore, the handle possesses greater strength and durability and is not lialole to be damaged through the rough usage to which such handles are ordinarily subjected and as would be likely to occur if it em- =bodied two relatively separable sectons.

Having thus described the invention, what I claim is:

1. A controller handle comprising en integral bandle body including a shank por tion having a controller-stern socket adjacent one nd thereof and an arm extending from the other end thereol, the said handle body being for1ned with aslot extending longitudinally of its shank and the arm portion and terminting at one end short of the outer end of the arm portion and at its other end opening into the said socket, and means for relatively adjusting the walls of the slot to effect contraction of the socket and thus cause the walls of the socket to bind the controller stem.

9. A controller handle comprising en integral handle body having a controller-stem socket adjacent one end and ornoed with a slot extending longitudinally thereof and opening at one end into the socket, the opposite feces of the sad body near the socket being ormed wth recesses, a clamping bolt having a head received in one of the recesses, said bolt having a shank extending tl1ro1 1gh the walls of the slot at the recesses, and a nut upon the bolt housed within the other recess, the bolt being adjustable to relatively adjust the walls of the slot to effect contraction of the socket.

In testimony whereof I afiix my signature.
