UNITED STATES JOHN T. SNYDER. OF LUZERNE, PENNSYLVANIA.
DFHLLING-l MACHINE.
SPECIFICATION forming part of Letterslatent No. 489,044, dated January 3, 1893.
Application iiled March 30. 1892.
To will whom t may concern:
, Be it known that I, JOHN T. SNYDER, a-citizen of the United States, residing at Luzerne, in theco'nnty of Luzerne and State of Penn- Sylvania,4 have invented a new and useful Drilling-Machine, of which the following is a.v speccation.
The invention relates to improvements in drilling machines. i
The object of the present invention is to simplify and improve the construction of drilling machines, to increase their strength and durability and to facilitate their adjustment to the character of the coal or other substance operated on. l
The invention consists in the construction and :novel combination and arrangement of parts hereinafter fully described, illustrated in th-e accompanying drawings and pointed ont in the claims hereto. appended.
In the drawings-Figure 1 is a perspective 4View of a drilling machine constructed in accordance with this invention. Fig. 2 is a horizontal sectional view. Fig. 3 is a detailview of the cog wheel. Figs. 4 and 5 are similar Fig. 6 is a horizontal section through the frame with the pinions and feed bar omitted.
Like numerals of reference indicate corresponding parts in all the figures of the drawings. I
1 designates a frame of general rectangular shape and having a removable section 2 and provided with a depending-L-shaped arm 3 which is adjnstably secured to a standard or brace 4. The frame 1 is provided with a laterally extending bearing 5 in which is journaled a short shaft 6 carrying a beveled cog wheel 7 at its inner end and having a crank handle 8 attached to its outer end and adapted to rotate it and a 'cog wheel 7, which drives pinions 9 and 10 arranged on a threaded feed or'drill bar 11. The removable section 2 of the frame which is secured to the other portion ofthe frame by vertically disposed pins 12, is provided with end bearings 13 and `a vse central bearing 14 to receive the feed-bar 11, and the pinions 9 and 1.0 are arranged between the intermediate bearing 14 and one of the end bearingsrl. The feed-bar 1l is provided on opposite sides with longitudinal slots or grooves 15; the pinion 9- is provided would become worn in a short time. .arrangement of the doubled cog wheel 7 and Serial No. 427.040. (No model.)
which fit in the grooves l5; and the pinion 10 is interiorly threaded and engages the threads of the feed-bar. rihe cog wheel 7 is provided with inner and outer coge 17 and 18 which mesh respectively with the pinions 9 and 10, wherebythe feed bar will be rotated and fed forward. Heretofore the amount of feed of the bar 11 was regulated solely by the number of threads to the inch, and as the hard- ,with interiorly disposed ribs or splines 1G est substances to be drilled require a small amount of feed to a great number of rotations i't is necessary to make the threads of the feed-bar very fine, consequently weakening the feed-bar and employing threads that B y the the pinions 9 and l0, a drilling machine may be readily constructed to obtain the number of rotationsof the feed berend the amount of feed to suit the character of the coal or other substances operated on by varying thc number of the cogs. The pinion 9 which is provided with the ribs or splines causes the rotation of the feed-bar, and the pinion l0. causes the feed-bar to be 'fed forward. The ends of the feed-'bar are similarly constructed and are adapted for the reception of a bit which may be placed on either end of the feed bar; and after the feed bar has been fed its entire length, the bit may be taken from one end and placed on the other and the removable section may be detached and the feed bar turned end for end and be placed in position for redrilling. By this construction the drilling machine may 'ne made either right or left hand to suit the operator. The lower end of the arm 3 which is attached to the standard or brace has its lower face rounded and it is provided with a slot.
lVhat l claim ls- 1. In a drilling machine, the combination of a frame provided with a laterali-y extending bearing and having a removable reversible section adapted to be turned end 'for end and provided with end bearings and a central bearing, arranged in alignment and disposedlongitudinally of the frame, a groove threaded feed bar arranged in the longitudinally disposed bearings, the pinion's disposed ou-the bar between the central bearing and one of the end ones, dne of the pinions engaging the grooves and the other the threads of the feed belga. short shaft journaled in the laterally extendingbeering and the cog wheel carried by the short shaft and havingadouble Set: of teeth meshing with the pinions, substan'tially'as described.
2 In a vdrilling machine, `the frame 1 having. a removable section 2, the latter being provided with end bearings 13 and a.V central to bearing 14, the feed bar passing through the three bearings 13, 13 and 14 and the pins 12 v my own I have hereto axed my signature iii I5 the presence of two Witnesses.
