FEED-GEAR FOR BORING-MILLS.
Specification of Letters Patent.
Patented May 30, 1916.
To all whom it may concern:
Be it known that I, FREDERICK F. CLARKE, citizen of the United States, residing at Franklin, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Feed- Gears for Boring-Mills, of which the following is a specification.
The object, construction, operation and utility of my improved feed-gear are herein set forth with sufficient clearness to enable those skilled in the art of boring-mill con struction to make and use the same.
The gear here shown is especially adapted to be applied to a vertical boring and turning-mill, winch is supplied with a sidehead, in addition to a vertical head, andthe object of the construction here shown is, to supply feed-gearing in which one main or primary element serves the double purpose of driving the train of gearing which causes the feed of both of said heads, and in order to make said object more clear, it is pointed out that, heretofore, what is above termed the primary element, has been supplied in duplicate,that is, the feed-gear for each head. has been separately supplied with said element, whereas, in the gearing here shown, said two trains of feed-gearing are driven from the one primary element, which is adapted to perform all of the functions of two such elements, as heretofore employed, thus simplifying the construction and operation of the machine, decreasing the space occupied and the cost of maintenance, and facilitating lubrication, inspection and repair of the machine, without in any respect lessening its power, capacity, utility or range of operation.
The construction whereby I attain said object is clearly shown in the drawing which forms a part hereof, and in which:
Figure 1 is an elevation of said gearing, Fig. 2 is a front elevation of a boring mill equipped with my improved feed gears.
Inasmuch as it is necessary to construct gearing which is employed for the purpose here specified, sothat the rate of feed may be varied to suit different kinds of work, the drawing shows gearing embodying such construction, and in order to make the same more easily understood, a definite line of drive is indicated through each train of gearing by shading the gears which are in operative action, with the exception that all the gears upon said primary element are shaded, because they are all keyed to the shaft and are thus positively driven. All unshaded gears may be considered as idle gears which may be selectively engaged and rendered operative for the purpose of changmg or varying the rate of speed as desired.
In detail, the construction here shown is as follows: I provide a primary drivingelement comprising a shaft 1, to which are keyed a number of gears 2, which, being keyed to said shaft 1, are all positively driven. Upon either side of said primary element, is mounted a separate secondary train of gearing, one to drive the side-head of the machine and the other to drive the vertical head. Said secondary trains are practically identical in construction, and, for this reason, reference numerals in duplicate will be applied thereto, since the description of one train is equally applicable to the other. Said secondary train comprises a shaft 3 upon which are revolubly but engageably mountedthe gears 1, which are selectively engageable and rendered operative by a key(not shown)within said shaft 3, which key is attached to the rack 5; a pinion 6 is operable to move said rack longitudinally, for the purpose of causing said key which is carried thereby to operatively connect any one of said gears 4 to the shaft 3; upon said shaft 3 are also mounted the gears 7, 8 and 9, through which a variable speed-drive may be had through the gears 10, 11 and 12, to the shaft 13. From said shaft 13 motion is transmitted to shaft '14 through the gears 15, 16 and '17. Said shaft 13 is provided with a selective key, for the purpose of operatively engaging any of the gears thereon, which key is operated by the rack 18, which is actuated by the .pinion 19.
23, which is connected to the shaft 24 to which is rigidly afiixed a worm 36 that upon the frame of the mill, to cause the vertical travel of said sideehead carriage and the ram 41 that is mounted therein. In order to simplify the drawings, and to more clearly illustrate the construction, the housing 22 is shown turned upon the shaft 22 at an angle of 90 degrees from its normal positlony 1n the actual constructlon,
7 gear 46 meshes with a g'ear 48 which is mounted upon and revolvesthe screw 50 "that causes the travel of; the carriage" 51 upon the cross-rail 52; gear-47 mesheswith a gear 49 that is mounted upon and .re- 'volves the shaft 53 for the purpose of" cansing the vertical, movement of the 7 vertical headed; I The gears 2 may be driven in any Copies of this patent ay obtainedifor suitable manner, and in actual practice, I find it suitable to drive the shaft 1 upon which said gears 4 are mounted, by means of a pulley 33, to which power may be transmitted from any suitable source, by
means of a belt. It is immaterial, however,
so far as my inventive idea is concerned, how gears 4: are driven. It is also immaterial to the suitable embodiment of my invention, whether the two heads, actuated by the gearing here shown, are a side-head and a vertical head, or Whether they are two vertical heads.
I claim:
1. In a boring-mill a vertical head, a side head, a train of secondary gearing operable to produce the feed-actuation of one of said heads, an additional train of secondary gearing operable to produce the feed-actuation of the other of said heads, in combination with a single primary element, consisting of gearing arranged to drive both of said secondary trains.
2. In a feed gear for a boringmill a vertical head, a side head, a primary, or main driving gear consisting of a plurality of spur gears of differing diameters rigidly mounted upon a shaft which is operable to drive said gears, in combination with a train of gearing adapted to be variably driven by said primarv gear and arranged to transmit and impart feed motion to said vertical head, and a second train of gearing substantially identical in construction with said first-mentioned train of gearing, adapted to be variably driven by said primary gear and to transmit and impart feed motion to saidside head.
In testimony whereof I afiixmy signature in presence of two witnesses.
