Description

Dec. 18, 1962 A. M. CARION UNIVERSAL SWITCH ADAPTER FOR DRILL STAND Filed May 13, 1959 INVENTOR.
ATTDRN EYS United 3,068,722 UNIVERSAL SWITCH ADAPTER FOR DRILL STAND Alvaro Mario Car-ion, 1621 Page St., San Francisco 17, Calif. Filed May 13, 1959, Ser. No. 812,866 4 Claims. (Cl. 77-7) This invention relates to a drill stand, and more particularly to a control mechanism for the drill or other tool being used.
The object of the invention is to provide an adapter for connection to the movable lever or handle of a drill stand whereby a convenient means is provided for turning the electric drill on or off.
' Another object of the invention is to provide an adapter which permits the control switch to be fastened to a manually movable lever so that a person can readily move a drill up or down and at the same time control the actuation of the drill by means of the control switch which is fastened to the handle lever by means of the adapter of the present invention.
A further object of the invention is to provide a universal switch adapter for a drill stand, which is extremely simple and inexpensive to manufacture.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawing, forming a part of this application, and in which like numerals are used to designate like parts throughout the same:
FIGURE 1 is a side elevational view illustrating the present invention.
FIGURE 2 is a sectional view taken through the manually movable lever.
FIGURE 3 is a sectional view taken on line 3-3 of FIGURE 2.
FIGURE 4 is a sectional view taken on line 4-4 of FIGURE 2.
FIGURE 5 is a perspective illustrating the adapter.
Referring in detail to the drawing, the numeral indicates a stand which includes a horizontally disposed base 11 and .an upright post or standard 12, FIGURE 1. A collar 13 is afiixed to the post 12 in any suitable manner, and the numeral 14 indicates a link which is pivotally connected to the collar 13 as at 15. A manually movable lever or handle 16 is pivotally connected to the link 14- as at 17, and the lever 16 is also pivotally conneeted to a movable sleeve 18 as at 19. The sleeve 18 is mounted for sliding or up and down movement on the post 12.
The numeral 20 indicates an arm which is fastened to the movable sleeve 18 as at 21, and a bracket 22 is secured to the arm 20, and the bracket 22 serves to support a conventional electric drill or tool 23. The drill 23 includes the usual rotary bit 24.
According to the present invention there is provided an adapter which is indicated generally by the numeral 25, and the adapter 25 is of U shape and has the lever 16 extending therethrough, FIGURE 2. The adapter 25 includes first and second spaced parallel side Walls 26 and 27 as well as a top wall 28. The numeral 29 indicates a block which is mounted between the lower portions of the side walls 26 and 27, and the block 29 is retained in place by means of pins or securing elements 30. The numeral 31 indicates screw members or set screws which extend through the block 29 and which engages the lower surface of the lever 16 so as to maintain the adapter 25 in the desired immobile position on the lever 16.
As shown in the drawing the numeral 32 indicates a control switch which is of conventional construction, and
3,d8,722 Patented Dec. 18, 1962 the control switch 32 is arranged outside of the adapter 25 and is fastened thereto. The control switch 32 is provided with a manually movable control button 33, and the switch 32 is fastened to the adapter 25 by means of securing elements 34, there being a backing or reinforcing plate 35 interposed between the switch 32 and the side wall 26. Slots 36 are arranged in the side wall 27, and the slots 36 provide clearance space whereby a tool such as a screwdriver can be extended through the slots 36 so as to gain access to the securing element 34, as for example when the adapter 25 is not on the lever 16, so that means is provided for fastening or unfastening the control switch 32 from the adapter 25.
The numeral 37 indicates an electric cable or wire which is adapted to be connected to a suitable source of electrical energy by means of a plug 38, and the wire 37 leads to the switch 32. The numeral 39 indicates a wire or electric cable which serves to electrically connect the switch 32 to the usual motor of the drill 33.
From the foregoing, it will be apparent that there has been provided an adapter which serves to connect a control switch such as the switch 32 to the movable lever or handle 16 so that a person can simultaneously move the lever 16 and at the same time operate the switch 32. Thus, only one hand is needed to perform this Work wherein with the switch not located on the lever 16, two hands would be required since one hand would be required to move the lever 16, while the other band would be needed in order to operate the switch 32.
In use, by gripping the lever 16 and moving the lever 16, the sleeve 18 will be moved up and down on the post 12. The arm 26 connects the bracket 22 to the movable sleeve 18, and since the bracket 22 provides a support for the drill 23, it will be seen that this manual movement of the lever 16 will cause similar movement of the drill 23 so that the bit 24 can be moved into or out of engagement with a work piece which is supported on the base 11.
At the same time, when it is desired to turn the drill 23 on or 011, it is only necessary to manually move the control button 33 and this will open or complete the circuit to the drill 23.
The switch 32 is fastened in place on the lever 16 by means of the bracket 25, and the switch housing is connected to the adapter 25 by means of a securing element 34. The lever 16 extends through the adapter 25, and by loosening the sections 31, the adapter 25 can be shifted to dilferent positions on the lever 16. After the adapter has been moved to the desired position, the screw members 31 are tightened so as to maintain the adapter 25 immobile in the desired position.
The parts can be made of any suitable material and in difierent shapes or sizes.
With the present invention, drilling jobs can be accomplished easier, speedier, and safer. Drill stands for electric hand drills are not built with a switch thereon, and with the present invention, a person can readily attach a switch to the drill stand handle 16 in a very short period of time and no alterations to the drill stand or to the drill being used is required. Different sizes of switches can be accommodated and some of the advantages of the present invention are as follows. Full control of the drilling process is provided at the users fingertips, and a faster and more accurate job is accomplished and it only takes one hand to operate the feed handle 16 of the drill stand and by merely stretching the users fingers of the same hand, the person can start or stop the drilling process in a short period of time. Furthermore, it is not necessary to clamp down the work piece since the user has a free hand to hold the same, so that a person can work faster. Furthermore, the user can concentrate on the work in a more satisfactory manner aoea'ma since it is not necessary to move the eyes away from the Work piece to start or stop the drilling process and the switch is within finger reach and adds to the safety with which the drill is being used. Furthermore, the electric drill will not be left running all the time since it is easy to start and stop the same so that there will be less noise and more peace for users, as for example when the drill is being used in the home. Also, the drill will last longer without heating up and there will be a saving in power and operating costs. Since there is no strain or pressure put upon the adapter, it can be built of very light material and the adapter can be made to trip the feed handle of various types of drill stands as desired.
Minor changes in shape, size and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.
