HAND DRILL AN PEDESTAL.
Application filed December 9, 1922. Serial No. 605,851.
To all whom it may concern:
Be it known that I, CHRISTIAN Booiunn,
a citizen of the United States,and a resident of New Britain, county of Hartford, State 6 of Connecticut, have invented certain new and useful Improvements in a Hand Drill and Pedestal, of which the following is a specification.
' The aim of the present invention is to provide a drill of such improved construction that it may be either held and steadied solely by the operator, as in the case of a hand drill or breast drill, or mounted in a suitable pedestal or support for sliding or feeding movement but against lateral movement.
More particularly, the object of the invention is to provide drills of this sort with frames of such construction that they may have sliding movement in opposed parallel grooves or ways in a suitable support where the character of work or conditions under which it is to be carried out require that the drill be held with greater steadiness or with less effort than would be the case if the drill were supported and guided solely by the operator. The drill frame is readily mountable within and detachable from the support and forms therewith a new and advantageous arrangement.
In the accompanying drawing, wherein I have shown for purposes of illustration one embodiment which the invention may take,
Fig. 1 is a side elevation of my improved drill and the support therefor, the drill and feed lever being shown in full lines in raised position and in broken lines in lowered position;
Fig. 2 is a sectional View taken substantially on line 22 of Fig. 1 through the frame of the drill and the pedestal.
Referring to the drawing in detail, the drill has a frame a provided with bearings b in which is journalled a drill spindle 0 comprising a chuck d for the drill e. The drill may berotated in any suitable manner; for instance, it may be provided, as shown, with a pinion f with which meshes a driving gear 9 suitably journalled in the frame and provided with the usual handle it. Secured to the frame is a handle 71 of any desired construction by means of which the operator may hold the drill when using the same as a hand drill. When so used, the act of turning the drill spindle by the handle 71 tends to cause the drill to wobble or gyrate making it extremely difficult, and in some instances practically impossible, for the operator to hold the drillsteady and true.
In order to hold the drill against such wobbling or gyrating movements, the frame of the drill, in accordance with the present invention, is provided with a pair of straight parallel side members 10, 10, adapted for engagement and sliding movement in the ways of a suitable support. These side members, as shown, are parallel to each other and to the axis of the drill spindle and are of uniform thickness.
The support, designated generally by the letter is, may be of any desired construction, that shown in the drawing being formed of metal. The body portion of the frame may, as illustrated in the drawing, comprise a casting of thin metal suitably strengthened by ribs 11. The support 70 may be secured to a base Z, a bench or other such member. Secured to the overhanging portion of the pedestal or support is are guide members 12 having on their opposed faces vertical grooves 13 in which the side members .10 of the frame are mounted for sliding movement. This particluar form of pedestal is shown by way of example only, the main consideration being that it is provided with a suitable slide-way, slot or guides adapted to receive the frame of the drill.
Connected to the pedestal by means of a I,
link 14 is a hand lever 15 detachably pivoted to the frame of the drill in any preferred manner, in the present instance this pivot being in the form of a screw or bolt 16. The drill frame is provided with a hole through which the screw 16 is adapted to extend, as will be readily understood from an inspection of the drawing. The lever 15 and link 14 form a toggle connection so to speak between the pedestal and the drill frame'in such manner that when the lever is raised in the position shown in full lines Fig. 1, the drill will be held up in this position. To lower the drill, the free end of the lever is pushed down whereupon the toggle connection is broken, the parts assuming the position shown in dotted lines Fig.1.
It is, of course, obvious that my invention is susceptible of various modifications and changes 'which are within the spirit of the invention without departing from the scope of the following claims, it being understood that the present disclosure of my invention is by way of illustration only and it is-not to be taken as restrictive of my conception.
I claim as my invention 1. In combination, a hand or like drill having a frame provided with parallel sides, a handle on said frame for holding the same, a drill spindle journaled in said frame between said parallel sides and extending in the general direction thereof, and manually operable means for rotating said drill spindle; and a support having guidew'ays in which the parallel sides of said frames have sliding movement.
2. In combination, a hand. or like drill having a frame including a pair of parallel side members of uniform thickness, a handle or the equivalent on said frame for holding the same, a spindle journalled in said frame, and a manually operable handle for rotating said spindle; a support having a pair of opposed grooves in which said side members are located for'sliding movement; and a feed lever connected to said support and drill.
3. In combination, a hand or like drill having a frame provided with a pair of parallel side members of uniform thickness, a handle or the equivalent on one end of said frame for manually holding the same, a spindle journalled in the other end of said frame between and in parallelism with said side members, and a manually operable handle for rotating said spindle; a support provided with a pair of guides having parallel grooves in their opposed surfaces adapted to slidably receive said side members of said frame of said drill; a feed lever connected to said support; and detachable means for pivotally connecting-said lever to said frame of said drill.
