. went-DRILLING BIT.-
Looaoea.
. i l To all whom it may concem:
Beit known that I, WALTER L. YOUNG, a
citizen of the United States, residing at Newport Beach, in the county oflOrz'lnge and State of California, have invented a new and useful \Vell-Drilling Bit, of which the following is a specification. k
At present it is'customary to bifurcate the cutting edge of well drilling bits by cutting away the middle of said cutting edge to form a notch or concave extending several inches toward the top of the tool and as the tool requires sharpening 'it is found necessary to take the tool from the well where the sharpening is usually done to a machine shop, so that the notch can be cut away with minimum expense. The expense, time and labor thus absorbed is a great item and an object of this invention is to avoid the cost thus entailed upon the operator and to so construct a drill of bifurcated character that the furcations can be readily-renewed at the well.
A further object is' to provide a well drilling bit of maximum length for repeated resharpening at the well, without excessive weight.
I re ard this invention as; ioneer in that the (lIlll is made of a-ladder ike form consisting of side rails united'at the top by the usual drilling bit head having the usual taper screw stem and having below the head cross bars that. resemble the rounds of a ladder and which hold the side members or rails in true relation to each other,.but which crossbars can be readily. cut away from time to time as the furcations are shortened so much as would, under the old method, require deepening of the notch between said ends, and I do limit the invention to theexact construction.
The accompanying drawings illustrate the invention.
same has become reatly worn. and ready for sharpening. ig. 5 is a cross section on-line w Figs; 1, 2' and 3. F1 6 1s a I longitudinal section of. a modified orm.
The top end of the drill is constructed with a strong body section or head l havmg the taper-thread I stem 2 corresponding to t i Specification of Letters Patent. Patented Apr. 28, 191 42. Applicationhled-Ootober 6, 1913. Serial No. 793,763. i
those on drills of ordinary construction,
and is integral with parallel side rails 3, 4, which terminate in the cutting tips 5, Gthat are constructed and sharpened in accordance with the usual practice. Integral with said side rails are the cross bars 7 connecting said rails at intervals; recesses,, preferably open spaces 8,being provided between said cross-bars, so that the general appearance of the. drill bod below the upper sect-ionrl is that ofa la der. Thecross bars 7, corresponding to the rounds of the ladder, may
be of any suitable. width 'and length determined by the size and nature of the bit, and the inter-bar spaces 8 are likewise proportioned. Between the cross bars and the inte'r-bar s aces may be twoinches acioss the bars to our inches. across the spaces. The
lower notch '9 is formed 'by the inside edges 475 of the loWerends .of/the side rails and by the bottom edge'of the lowermost cross bar, 'which in the process of sharpening will be conc'avedfon. its under-side to supply the" preferred construction. of bit.
In practical use as the ti s 5 and 6fbecome worn they are sharpened rom time to time until the concave 9fis too sh allow for satisfactory use, and then when the'bit isheated .for the purpose of sharpening, the lower round or cross bar 7 will be cut away, thus utilizing. the lowermost one of the spaces 8; and this is continued from time to time until the upper solid end of the bit is reached. All this is easily accomplished by using the ordinary-bit sharpening means at the well and without the necessity of taking the bit to the machine shop as heretofore.
The inter-cross-b'ar spaces are usuallyentirely, open as shown in Fi 1, but where desired a thin web 10. (see hig. 6) may be formed, the'same being of greatly reduced thickness so that as the sharpening process .proceeds, such web may be readily cut away, thus leaving an open space or notch bet-ween the tips of the bi The nature of the invention is such that the bit rotates in the hole 'more freely because it does not meet with so much resist-' ance from the thick mud which has been necessarily I mixed up in drilling the hole; and the mud and water in the hole are mlxed more thoroughly and with greater facility so that themass is thinner and the resistance terminating at one end of t 16 so that durin advantages arise from the open nature of the body of the bit, the same being provided in the preferred form with one or more openings of comparatively large dimensions operation the tool may rotate in the hole a er the usual way except more freely as solid parts of the tool will pass through the thin mud more easily than to turn the entire mass of thick and sticky mud as heretofore ,with'bits having no such openings therethrough.
I 'claim:
1; A well-drilling bit com rising side rails e bit in cutting tips; and cross bars connecting the rails at intervals.
2. A well-drilling bit comprising side rails terminating at one end in cutting tips; the space between the rails being recessed at intervals; and cross bars connecting the rails 20 rails extending downward from the head, and cross bars uniting the side rails at intervals between the head and the tips, said tips being sharpened.
In testimony whereof, I have hereunto set my hand at Newport Beach, California, this 29th day of September, 191 I VALTER L. YOUNG.
In presence of C. H. WALLACE, \VALTERW. WHITE.
