H. B. MAYBERRY TOOL FOR MANUAL DIRECTION Filed Dec. 6, 1922 ATT NEY To allwhomit may concern:
Nov. 27, 1923.

Application filed December 6, 1922.. Serial No. 605,316.
Be it known that I, HAGAR B. MA BERRY, a citizen of theUnited States, and a resident of Gladstone, county of Somerset, and State of New Jersey, have invented certain new and useful Improvements in Tools for Manual Direction, of which the following is a specification.
This invention relates to an improved tool for manual manipulation, and while it is applicable to many different uses in metal working,carpentry and the like, it is illustrated and described, for the purpose of clear understanding, as used with a hair clipper such as used by barbers.
The object of the invention is to provide such a device which will not necessitate a stand for an electric motor, but secures the motor directly to the arm of the person who is directing the tool, and this permits the use of a short length of flexible shaft or other connection between the motor and the tool.
The invention is illustrated in the accompanying drawing, in which Figure 1 is a perspective view showing the tool used as a hair clipper. Figure 2 is a front view of the motor. Figure 3 is a side view of the motor. Figure 4 is a detail section of a form of connection between the shaft and motor.
'Figure 5 is a perspective view of a form of bail for the motor, and Figure 6 is a perspective view of the clip of the bail shown in Figure 5.
The motor is shown at 10 and can be of any of the usual types of small electric motor, and it is adapted to drive any form of tool, and I show in the drawing a hair clipper 11 which is operatively connected with the motor by a suitable connection, usually a flexible shaft 12 and a flexible casing 13 for the shaft. The clipper is an ordinary article of commerce and is not described in detail herein, as the invention is applicable to different kinds of cutters, clippers, and in fact any tool. that is to be manually directed as to the work it is to accomplish.
It has previously been the custom to have a long length of flexible shafting driven from a fixedly supported motor, and this lon length of shafting not only becomes twisted very often, but it makes the operation of an article like a hair clipper uncertain on account of the long length or weight of shafting tending to pull down on the end of the cutter, and also on account or" the reduced power caused by the length of flexible shafting necessary, since many sharp turns very often taken place in a long length of flexible shafting, andif a short length is used it 'is'necessary to turn the chair in which the person is seated,'instead of the barber going around the person.
' To overcome this'I permit the use of a short length ofjshafting, and to give the fcl ipper more efficiency on account of the sllght loss of power in such a substantially straight short length of shafting, I secure the motor to the arm of the person using the tool by means of a suitable clasp or bail. In the form illustrated I show a bail 14', and'I usually supply enough flexible shafting so that the motor can be supported adjacent to the elbow, which is the point of most convenience and where it can be carried with the least amount of effort, and so that in the movement of the forearm incidental to directing the tool the motor remains substantially aligned with the tool.
In the form shown the bail 14: is fastened over studs 15 on the sides of the motor, and for quick adjustment I make the bail of two members, one of them being a strip of bendable metal, the strip being shown at 16 and having a hole 17 at one end by means of which it is attached to one of the studs 15 on the motor, and passing at its other end 18 through a clip 19, which clip has its end 20 provided with a hole 21 which is secured over the otherof said studs 15, the clip 19 being usually formed of one piece of metal, which in the form of ears are bent over as at 22, these ears-being flanged at their ends, as at 23, these flanges acting asabutments against which a spring 24; has its ends caught, the spring 24: being adaptedto press against the bendable strip 16 to hold it in ad usted positions. I prefer to bend the end 18 of the strip 16 over, as at 25, to prevent the accidental separation of the parts.
When the motor is to be put on the arm the strip 16 can be pulled out through the clip 19 as far as desired and the arm slid in under the bail and over the motor until the motor is in the proper place, and then by grasping with the other hand and pressing down on the bendable strip 16 it is pushed down to grasp the arm as shown in dotted outline at 26 in Figure 2, so that the motor does not sway, but is held substantially close to the arm and is securely fastened. The motor is supplied by eleo-' trical current through a suitable cord or Wire 27. r
I claim:
1. A tool for manual direction comprising an electric motor having means for attaching it to the human arm, a tool for grasping by the hand, and an operative connection between the motor and the tool.
2. A tool for manual direction comprising an electric motor, a bail on the motor, said bail being adapted to clamp the human arm adjacent the elbow, a tool for the hand, and a flexible shaft connecting the motor and the tool. 1
3. A tool for manual direction comprising an electric motor, a bail on the motor, the bail being formed of abendable strip of metal, and a frictional adjusting clip to receive one end of the strip.
4. A tool for manual direction comprising an electric motor having a band for attach- 5. A tool for manual direction comprising an electric motor, a bail, said bail comprising a strip of bendable metal and also comprising a clip formed of metal having ears bent over to form a socket, said ears having flanges at their ends, and a flat spring sprung under said flanges, said clip receiving one end of said strip so that it frictionally engages the spring, the other end of the strip and the clip being pivotally connected to the sides of the motor.
In testimony that I claim the foregoing, l have hereto set my hand, this 4th day of December, 1922.
H. B. MAYBERRY.
