SUPPORTING AND OPERATING DEVICE-FOR DRILLS AND THE LIKE Filed 001:. t 25, 1957 INVENTOR.
ATTOQHE United States Patent C) SUPPORTING AND OPERATING DEVICE FOR DRILLS AND THE LIKE Merritt H. Baublitz, Norfolk, Va. Application October 25, 1957, Serial No. 692,350 1 Claim. (Cl. 77--7) This invention relates to an improved supporting and operating device for drills, power-hammers, and the like, in overhead drilling operations.
The primary object of the invention is to provide a simpler, more practical, and more efl'icient device of this kind which is adjustable to securely support drills and hammers of different forms, and which has foot-pedal operated means for holding the drill or hammer in operative position and feeding the same upwardly to overhead work, whereby the hands of the operator are freed to guide and adjust the drill or hammer, and overhead drilling operations are rendered substantially easier, quicker, and less physically taxing on an operator.
Another important object of the invention is to provide a device of the character indicated above which is composed of a small number of simple, readily available, and easily assembled parts.
A further object of the invention is to provide a device of the character indicated above, which can be made in well-finished, rugged, and serviceable forms at relatively low cost.
Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.
In the drawings:
Figure l is a side elevation of a device of the invention, showing in phantom lines drill elevating positions of component parts;
Figure 2 is a left-hand edge elevation of Figure 1;
Figure 3 is an enlarged perspective view of the upper part of Figure 1, with the drill removed; and A Figure 4 is a horizontal section taken on the line 4--4 of Figure 3.
Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the illustrated device comprises a vertically elongated ground-engaging standard having on its lower end a ground-engaging foot plate 12. The standard 10 is preferably in the form of square tubular steel stock having opposed side walls 14 having therein vertically spaced and transversely aligned pivot bolt holes 16.
The device further comprises a vertically elongated, vertically movable drill or hammer supporting bar 18, which is preferably of square tubular steel stock, like the standard 10, and has opposed side walls 20, 20 having therein vertically spaced, transversely aligned bolt holes 22. The bar 18 has a lower end 24 adapted to rest upon the ground G, with the foot plate 12, when the device is not in operation.
The standard 10 and the bar 18 are maintained in spaced parallel relation and in operative relation by a link 26, preferably in the form of an angle iron, which extends between upper portions of the standard 10 and the bar at one side thereof, and has pivot bolts 28 and 30 extending through opposite ends of its vertical flange 32 and engaged through selected aligned bolt holes 16 and 22 of thestandard side walls and supporting bar side walls. A foot operated lever 34 is secured by and pivoted on pivot bolts 36 and 38 extending through alinged bolt holes 16 and 22 of the standard 10 and bar 18, and is positioned at the opposite side of the standard 10 and the bar 18 2,879,677 Patented Mar. 31, 1959 from the link 26. The lever 34 extends inwardly beyond the standard 10 and has on its free end a foot pedal or treadle 40. When the operators foot is pressed downwardly upon the treadle 40, the lever 34 is depressed and the supporting bar 18 is elevated, as indicated in phantom lines in Figure l, to apply a drill or hammer to an overhead Work-piece W. The rows of bolt holes 16 and 22 in the standard 10 and in the supporting bar 18 are provided to enable adjusting the pivoted points of the link 26 and lever 34 along the standard 10 and supporting bar 18 for different working conditions.
On the outer side of the upper part of the supporting bar 18 is a seat 42 for supporting the lower end of such as an electric drill D. The seat 42 comprises a first vertical tubular rest 44 fixed in suitable manner to the outer side of the bar 18, and a second outwardly projecting rest 46 fixed on the outer side of the rest 44 and depressed relative to the upper end of the rest 44. The rest 44 accommodates the lower end of the housing 48 of the drill D, while the rest 46 accommodates the handle 50 of the drill D. An inverted L-shaped retaining plate 52, to extend through the drill handle 50, has flanges 54 and 56 securable to the rest 44 and 46 by screws 58 and 60.
Above the seat 42 is a drill clamping assembly, generally designated 62, which comprises vertically spaced.
pairs of horizontal longitudinally adjustable bars 64, 65 engaged with opposite sides of the supporting bar 18 and secured thereto by bolts 66 traversing the bar side walls 20, 20, and passing through selected longitudinal spaced bolt holes 68 in the bars 64 and 65. The outer ends of the bars 64 are fixed to opposite edges of a vertically elongated concave plate 70 which is arranged to conformably engage the adjacent side of the upper reduced portion 72 of the drill D. Upper and lower split clamping bands 74 and 76 are secured to the concave plate 70 for clampingly embracing the reduced portion 72 of the drill D.
In operation, the drill D being seated and clamped on the supporting bar 18, the operator applies the upstanding bit 75 of the drill D to the overhead work W by pressing downwardly upon the foot lever treadle 40 so as to move and hold the supporting bar 18 to the required elevation. Downward withdrawal of the drill bit 75 from the work W requires only relaxing of downward pressure upon the treadle 40.
Although I have shown and described herein a specific embodiment of my invention, it is to be understood that any change or changes in the forms of and in the relative arrangements of components thereof are contemplated as being within the scope of the invention as defined by the claim appended hereto.
What is claimed is:
A drill support comprising a vertical bar having an upper end, drill mounting means comprising a fixed drill seat on said bar at one side thereof and spaced below said upper end, and clamp means on said one side of the bar and spaced above said seat, said clamp means comprising an element having drill-clamping arms thereon, and an arm fixed to and extending laterally from said element, and means securing said arm to said bar and pro viding for lateral adjustment of said element toward and away from said one side of the bar.
