CONTROL MEANS FOR PORTABLE ELECTRIC TOOLS Filed Spt. 4, 1944 i g m INVENTOR ATTORNEY Patented lflpy 4, 1948 CONTROL 8 FOR-PORTABLE ELECTRIC TOOLS Reynold Happe, Plttstown, N. 1., assignorto The Sin ger Manufacturin Company, Elizabeth,

- N. 1., a corporation of New Jersey Application September 4, 1944, Serial No. 552,589

10 Claims. (01. 200-157) This invention relates to portable electric tools and, more particularly, to the switch mechanism thereof. It has for its primary object a switch mechanism of simple and effective construction,

automatic in operation in the sense of requiring no special manipulation by the operator to effect the openingand closing of the switch at times appropriate to the work in hand, and capable of organization as a convenient unit for'ready installation in the handle of any particular tool.

With the above and other objects in view, as will hereinafter appear, the invention comprises the devices, combinations and arrangements of parts hereinafter set forth and illustrated in the accompanying drawings of a preferred embodiment of the invention, from which the several features of the invention and the advantages attained thereby'will be readily understood by those skilled inthe art. 1

In the drawings:

Fig. 1 is a broken-out sectional view illustrating the preferred form of switch mechanism installed in the handle of a portable electric tool.

Fig. 2' is a somewhat diagramamtic, sectional view, with parts broken out, to illustrate the functioning of the switch. v

Fig. 3 is a section on the line 3,3 of Fig. 1.

Fig. 4 is a perspective view of the switch contacts and associated elements.

Fig. 5 is a perspective view of a switch actuating element and its supporting stud.

Referring to the drawings, the rearend IU of the housing of a portable electric-tool, such as a drill, is shown as terminating in a pistol grip handle ll of generally hollow construction and partially open at the rear. The handle is closed at the bottom by a butt plate I2 on the inner face of which is anchored the current-supply cable l3. The current leads pass from this point to the switch unit and thence to the motor mounted in housing l0.

- bodily insertable into the handle ll through the opening in the rear thereof. The switch unit is adapted to be secured to the handle by screws l8. Within .the housing 20 is a snap-switch of any suitable construction. As illustrated, it comprises two sets of stationary, spring contacts 22 and 23 the adjacent, free ends of which are separated by a sliding contact member 25 consisting of a block of insulating material carrying the contact pieces 26. The contacts 22 are connected respectively to the leads I9 from cable i3, and the contacts 23 carry contact buttons 24 adapted toensa e the springcontacts it when the unit is inserted into the handle, as above stated. The sliding movement of contact member 25 may be limited as by stops 46 (Fig. 2). In the upper position of the contact member 25 the circuit is broken. In the lower position of the contact member the circuit is closed by the contact pieces 26 respectively bridging pairs of contacts 22 and 23.

Movement of the sliding contact member 25 is eiTected by a snap-action spring 28 adapted to be thrown from the Fig. 2 (open-circuit) position,

through dead-center, to a closed circuit position represented by the dash-and-dot line designated 40. As indicated, one end of the spring 28 engages a lug 21 projecting from sliding contact member 25, and the other end of the spring surrounds a pin '29 projecting from an actuator 3|, the sliding movements of which eifect the throwing of the snap-spring 28.

The upper end of actuator 3| is provided with bent up, spaced, wing portions 34. As shown in The rear bearing of the motor shaftis mounted in a support ll carried by the frame of the motor and to which the handle is secured by screw l5.

Depending from an insulating block 42, secured to the support M, are two spring contacts [6 con- Figs. 1, 2 and 3, the actuator is mounted within a channel member 43 secured to the housing 20. Sliding movement of the actuator within the channel member is limited by suitable stops, as indicated at 33. These stops are provided by bosses on the member 43, which bosses are internally threaded to receive the screws l8. A track member 32 is secured to the back of the member 43 (Fig. 3) and receives rollers 38 to be referred to later. The actuator 31 is biased toward its Fig. 2 (open-circuit) position by a pair of springs 41 the lower ends of'wh-ich are anchored on a crosspin 44 extending through the side-walls of the channel member 43. The upper ends of springs I are anchored on a cross-pin 35 which extends through the actuator wings 34.

According to the present invention, the snapswitch is actuated by a member mounted for bodily, rectilineal movement relatively to the tool itself and so located as to be engaged by the hand of the operator, and moved to switch-closing position, without special attention by the operator, that is, as an incident of his normally grasping the handle oi. the tool and applying the tool to the work. Also, such member is so arranged as to constitute a part of the switch unit assembly.

For these purposes there is provided in this instance a grip-member 31 located along the rear of the pistol-grip handle H and suitably shaped to fit the contour of the body of the handle for convenient engagement by the palm of the hand of the operator when the tool is grasped. As indicated in Fig. l, the grip-member 3'! is located between channel walls 45 formed integral with the handle ll. Projecting from the inner face of grip member 31 is a block 41 which carries rollers ll located within the track member 82. By reason of this construction the gripmember is movable longitudinally of, but is retained against outward removal from. the track member. Projecting from the block 41 is' a stud 36 the outer end oi which carries the cross-pin 35, thereby connecting the grip-member 31 to the wing portions 84 of the actuator 3|. The actuator is thus positively operated by longitudinal movement oi the grip-member relatively to and in the direction dictated by the track member.

In this preferred form oi the invention the track member is set at what, for identification, will be referred to as an acute angle to the major longitudinal axis. 1. e. the work-thrust axis, of the tool housing ID. More specifically, the track member may be said to be arranged substantially parallel to the axis 01 the handle of the tool, which axis, as usual, is set at an angle to that of the tool. As the result, when the operator grasps the tool and applies a normal work thrust to it in the direction indicated in Fig. 1, the gripmember slides or rides up the rear of the handle, in opposition to the springs II, in the direction or motion indicated in Fig, 1 and thereby automatically throws the snap-switch to close the motor circuit. This condition continues, course, just so long as the operator continues to apply work thrust to the tool. As soon as such thrust is relieved, springs ll restore the grip-member 31 to its former position and coincidently throw the snap-switch spring 28 to its circuit-opening position.

The described mechanism thus incorporates the combination or a snap-switch, having its own contact-actuating spring, and additional spring-controlled means for operating the snapswitch, the spring or springs of such additional means acting to bias the same in a direction to throw the snap-switch to its open-circuit posi tion. As will be understood, the bias of such additional spring (in this instance the springs II) is sufilcient to overcome the resistance to switch-opening opposed by spring 28 when the latter is in its switch-closing osition.

It will be noted also that there is nothing critical about the extent of movement required of the grip-member to close the switch, any movement suilicient to throw the snap-spring beyond its dead center position being sufllcient. Nor is undue pressure required to maintain the switch closed. As soon as the snap-spring has Passed its dead-center position, and unless the actuator is moved clear to the upper limit of its travel into engagement with upper stop 33 (which is quite unnecessary), the thrust of the snap-spring actually opposes the switch-opening tension of springs 4|, with the result that the thrust necessary to maintain the witch closed is represented simply by the necessary excess of the tension of springs 4| over the expansive force of spring 28.

Having thus set forth the nature of the invention what I claim herein is:

1. In a portable electric tool including a housing and a motor therein, a hollow handle attached to said motor housing, said handle being set at an acute angle to the work thrust axis of the tool, a motor switch located within the handle, a manually operable member for operating said switch, said member mounted for bodily sliding movement relatively to the handle, said movement being in a direction'substantially parallel to the axis of said handle and therefore movable at an acute angle to the work thrust axis of the tool.
