Specification of Letters Patent.
Application filed December 23, 1912, Serial No. 738,140. Renewed March as, 1914. Serial No. 328,096. I
To all whom it may concern Be it known that I, ANDREW J. CARTER, a citizen of the United States, residing at the city of Victor, county of Teller, and State of Colorado, have invented certain new and useful Improvements in Hammer Drills; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters andv figures of referencemarked thereon, which form a part of this specification.
My invention relates to hammer drills and may be said to constitute an improvement over the machine of'my application Serial No. 661,288, filed NoveinberQOth, 1911.
The principal object of the present invention is to provide means for feeding water through the drill steel to the cutting face thereof.
Other objects will appear hereinafter as I proceed with that embodiment of the invention which for the purposes of the present application I have illustrated in the 'accompanying drawings, in which:
' Figure 1 is a longitudinal, horizontal, sectional view showing the operating niecha nis m in plan with certain of the partsbroken away. Fig. 2 is a vertical section-taken approximately upon the line'22 Fig. 1, and looking in the direction of the arrow. Fig. 8 is a cross section upon the line 3+3 Fig. 1, looking in the directionof the .arrow, the parts being shown upon a larger scale. Fig. 4 is a central longitudinal section taken upon a line corresponding to the line -14-'-, Fig. 3,.and looking in the direction of the arrow. Fig. 5 is a detail end view of the striking surface of the hammer.
The same reference characters refer to like parts in each of the views.
Let the numeral 5 designate the cylindrical portion of thedrillcasing, which is closed at the ends by plates 6 and 7 secured to the cylindrical portion by means of bolts 8, or
other suitable fastenings. A removable cover 9, of a curvature corresponding to that of the casing, is mounted in the top thereof and near the rear end. Depending from the bottom of the casing near the rear end is a sleeve 10 which is adapted to beconnected shaped ways withinwhich ridesa hammer 13, having a rearwardly extending portion 14, upon which is pivotedat 15 a stem 16 having a T-head 17 Curved leaf springs 18 are "secured upon the portion 14: of the hammer and hear at their extremities upon'stem l6, tendingto hold the latter in line with the axis of the hammer. A spiral spring 19 surrounds the stem 16 and bears at one end against the hammer 13 and at the opposite end against the partition 20. Partition 20 has a vertical slot 21 therein, through whi h stem 16 slides. a i
PatentedN ov. 3, 1 914. I
A transverse shaft22 is ournaledin bear ings 23 which are split horizontally, the
lower half of each bearing being in the easing and theupper' half being in the cover 9, whereby the shaft may be lifted out ofplace when the covert) is removed. i
Midway of its length the. shaft 22 is formed into three U-shaped arms 24 extending radially at angles of 120 degrees, the
Integral with the forward plate 6 are rearwardly extending arms 31 across the ends of which is mounted a flat bar 32 having a circular opening in the middle to form a journal for one extremity of the sleeve 33 which also passes through a circular opening of the same size in the plate 6. The gear wheel 29, above mentioned, is secured upon this sleeve 33 by means of a set screw 34.
The drill steel 35 is slidably mounted within the sleeve 33 but is prevented from turning therein by the lug 36 which is set into the steel 35 and engages a slot 37 in the sleeve. The steel 35 has a duct 38 extending axially from one end to the other, the duct being enlarged at its intersection with the rear face of the drill to form a socket 39 of spherical contour.
' The spherical head 40 of a water conducting tube 41 is arranged to fit within the socket 39, the engaging surfaces being smooth to permit rotational movement. The tube 41 is threaded into a T-coupling 42, into the other openings of which are threaded'shafts 43 and 44 forming together a rock-shaft which is mounted in journals 45 and 46, the shaft 43 having a collar 47 thereon, held in the desired position by a set screw 48. In the preferred embodiment of my invention the shaft 44 is made in the form of a pipe and has a water hose 49 upon its outer extremity, leading from any source of water supply. Other forms of water connections may be employed, however, and in this respect I desire to limit my invention only as indicated in the claims hereunto appended.
A spring 50 is coiled about the rock-shaft and bears at one end against the back of the tube 41 and at the opposite end against the casing 5 whereby the tube head 40 is held in engagement with the socket 39 at all times.
The hammer 13 has a socket 51 cut into its striking face, of a size and shape to surround the tube 41 and spherical head 40, when the hammer is in contact with the drill steel.
From the foregoing description the operation of my improved drill will be evident.
' Rotation of the shaft 22 serves to actuate the hammer and at the same time, by means of the spiral gears 25 and 26, shaft 27, and gears 28 and 29, to slowly rotate the sleeve 33 carrying with it the drill steel 35. Water is continually fed through the hose 49, pipe 44, tube 41 an opening leading from the spiral head 40 into the duct 38 and thence to the cutting end of the drill steel, the spring 50 causing the head 40 to follow the drill steel at each stroke of the hammer. The hose 49, being flexible, will permit of the slight rocking motion to which the pipe 44 is subjected by the reciprocation of the drill steel.
I claim as my invention:
1. In combination a drill steel having a water duct extending longitudinally there through, a pivotally mounted water conductor having an opening adapted to register with the rear end of said duct, a spring arranged to press said conductor against the rear surface of the drill, and a hammer having reciprocating motion only, said hammer having a recess in its striking surface arranged to surround a portion of said conductor.
2. In combination a drill steel mounted for reciprocative and rotational movements, said steel having a water duct extending axially there through, a pivotally mounted water conductor having an opening adapted to register with the rear end of said duct, resilient means for causing said opening and duct to remain in register during the reciprocation of the drill steel, and a hammer having reciprocating motion only, said hammer hafvinga recess in its striking surface arranged to surround that portion of the conductor which is within the path of the hammer.
3. In a hammer drill, a drill steel, means for imparting thereto reciprocative and rotary motions, said steel having a water duct extending axially there through the rear end of said duct being enlarged to form a socket of spherical contour, apivotally mounted water conductor having a spherical extremity adapted to fit within said socket, saidspherical extremity having an opening adapted to register with said duct, and resilient means arranged to act upon the water conductor for holding its spherical extremity in position within said socket during the reciprocation and rotation of the drill steel.
