Patented Feb. 22, 1944 UNITED STATES PATENT OFFICE 2,342,601 DRILLING MACHINE FDR CONCRETE Carl A. Pyle, Wichita, Kans. Application November 16, 1942, Serial No. 465,783
1 Claim.
Referring to the drawings:
Fig. 1 is a side elevation of the machine.
Fig. 2 is a longitudinal section of the machine.
Fig. 3 is a sectional view taken on line 33 in Fig. 2.
Fig. 4 is an 4-4 in Fig, 1.
Fig. 5 is an enlarged cross section taken on line 5-5 in Fig. 3.
enlarged cross section taken on line convenience of illustration.
The invention a frame I,
plates having hubs A and B respectively, the hubs being axially bored for ball bearings 4 mounted therein.
It will be seen that hub B has a circular disc 5 as an enclosure for the outer end of its respective bearing, and a cap 6 to cover the plate and secured oil tight to its hub. The hub A of the other plate has an annular washer 1 seating on the outer end of the bearing and being plurally apertured therearound. Seated on the washer is a packing 8 as an oil tight means for a journal later described, and the said hub being oil tight sealed by an apertured cap 9 secured to the hub, and each of said caps being secured to its respective hub by a plurality of screws I0 spaced therearound.
It will now be seen that the elliptical frame and plates for each side thereof forms a casing for lubricant.
Journalled in the bearings is a shaft H that is connected to an electric motor I2 axial therewith, the motor being supported by a brace I 3 secured thereto and to said drilling machine.
The portion of the shaft extending through the casing has a cam I4 eccentrically secured thereto and rotatable therewith, the function of which is later described.
Secured to the lower end hollow cylindrical element l5 as a barrel, the upper end of which has an annular flange C out Wardly extending, seating on the casing and being secured oil tight by cap screws l6 spaced therearound.
Positioned in the barrel is a spring ll through which extends a plunger I 8 that is adapted for reciprocating movement of the oil casing is a cam will act to move the plunger inward repeatedly, the head having a pair of tongues D oppositely disposed thereon and adapted to slidsaid elliptical frame as shown in Fig. 4.
It will be seen that the cam at its eccentric extension terminates as at E whereby an offset in the cam is formed to permit an instant rebound of the plunger as tensioned by its spring for repeated strokes for the drill bit 21 as the shaft turns. It will be understood that the drill bits of different diameters may-- be secured to the outer end of the plunger by a coupling 28, the adjacent end of which is attached to the shaft by a key 29 diametrically passing therethrough, the shank F of the drill bit being secured by a pair of set screws 30 oppositely disposed, said set screws merely to retain the bit to the plunger but not to resist the force of stroke as said bit snugly engages with the end of the plunger.
Positioned on the upper end of the oil casing is a handle 3|, removably secured by cap screws- 32 as shown in Figs. 1 and 2. Said handle being removable is means to substitute therefor a carrying shaft which is a convenient supporting. means for overhead drilling, said shaft comprising a pair of members 33 and 34 telescopically engaging and being stationari'ly secured by a pin 35 diametrically passing through the interlapping portions as shown in Fig. 6. It will also be seen that a short length of shaft, is secured to. the. oil casing where the handle is removed,. said shaft being threaded. and telescopically engagingin the upper member of the support. To raise: and lower the machine as carriedby the support there is provided a threaded collar 38 to engage on the shaft, the collar having a radially extending. handie 35 to turn the same, the arrangement of which is to advance the machine as the hole is drilled.
To remove the head f om the oil casing, plate 3 isremoved and likewise blocks 40 oppositely dis posed in the frame and being one side of the groove, and as shown in Figs. 2 and 4, whereby the groove is opened at one side to free the head for side movement from the casing, it being understood that the plunger is first removed from the head.
Such modifications may be made as lie within the scope of the appended claim.
Having fully described my invention what I claim as new and desire to secure by Letters Patent is:
In a drilling machine for concrete, a casing comprised of a frame elliptical in contour'whereby a major and minor axis is established and the said frame having an opening therethrough, and heads to close the same oil tight, said frame having a pair of grooves internally and oppositely disposed and being in parallelism with each other and with the major axis of the frame, the corresponding sides of the grooves being removably secured asaccessible means into the grooves, a motor-driven shaft journalled in the casing and having, a cam secured thereto, and being; positioned in. the casing, a head having an opening therethrough and, a pair of tongues externally of the head and. oppositely positioned thereon in parallelism to engagein the grooves, aroller journalled to operate in the opening of the head and being engaged by the cam to move thehead in one direction, there. being a spring to move the head in the other direction at the instant of the cams disengagement with the roller, and the said head having a drilling bit and means to connect the same-to the head.
