Original application filed June 1, 1912, Serial No. 152.226. Divided and this application filed May 21,

1924. Serial No. 714,972.

T 0 all whom 2'2 may concern:

Be it known that I, ALBERT BALL, a citizen of the United States, residing at Glaremont, in the county of Sullivan and $tate of New Hampshire, have invented certain new and useful Improvements in Channeling Machines, of which the following is a full, clear, and exact specification.

My invention relates to channeling mal0 chines.

An object of my invention is to provide an improved channeling machine. Another object of my invention is to provioe improved feeding mechanism for a channeling machine. A further object of my invention is to provide improved feeding mechanism for the tool-actuating mechanism of a channeling machine. A still further object of my invention is to provide an improved feeding mechanism for the tool-actuating mechanism of a power driven channeler having an improved arrangement of parts. These and other objects and advantages of my inven tion will, however, hereinafter more fully appear.

In the accompanying drawings I have shown for purposes of illustration one form which my invention may assume in practice.

In these drawings, Fig. 1 is an end elevation, partially in vertical section, of a channeling machine in which my improved feeding mechanism is incorporated.

Fig, 2 is aplan view, partially in horizonta-l section, of the mechanism shown in Fig. 1, with certain parts removed.

Fig. 3 is a detail in side elevation showing one of the controlling levers.

Fig. 1 is a horizontal transverse sectional view on an enlarged scale taken substantiallyon line l-'l of Fig.

In this application, which is a division of my copending application, Ser. No. 452,226, stone working machines, filed June 1, 1912, I

have shown for purposes ofillustration, a

channeling machine of standard form having a base or mainframe 1 which may be of any suitable type of construction, having axles 2, having thereon truck wheels 3 whereby the machine may be moved on the bottom of the quarry along the usual tracks con sisting of rails 4. Suitably mounted on the base in suitable brackets thereon is a trunnion bar or shaft 5, Whereon is pivoted in any suitable manner an upright standard 6, the same consisting of upright supporting and guiding members united at the bottom and at the top joined by arch pieces or yokes 7. The standard may be positioned at any desired point lengthwise of the machine upon the trunnion shaft 5, and may be bolted at any desired angle in any suitable manner, as by the use of adjustable braces 8, pivotedly connected at their upper end to the standard and at their lower ends to a bar or shaft 9 mounted on the base 1 at the back of the machine.

Mounted for adjustment upon the standard 6 toward and away from the work is a sliding frame 10 to the bottom of which a sliding guide 11, for a crosshea-d 12, is bolted. The crosshead 12 carries a gang of cutting tools 13 suitablysecured thereto and which crosshead is secured, as at 1 1, to a piston rod 15 adapted to be actuated by suitable tool-actuating mechanism, generally designated 16, of the same general type described'in my co-pending application mentioned above, and which is driven through connecting rods 17 and a crank shaft 18, suitably journaled on. the sliding frame 10 which is driven through suitable gearingltl from a suitable motor 20, herein an electric.

motor, which may be mounted on any suitable part of the machine, but is preferably secured to the sliding frame.

The sliding frame 10 may be raised and lowered on the standard toward and away from the work by feeding mechanism of improved form, herein being provided for this purpose with a non-rotatable nut 21 suitably carried by the frame 10, said nut receiving therein a rotatable feed screw 22 which is journaled in a suitable bearing 23 carried in a suitable manner by the standard. This feed screw is rotated by suitable means, to be hereinafter described, providing for an angular adjustment of the standard and parts carried thereby without disturbing the driving connection with the feed screw. Suitably mounted on the base 1 is a driving motor 24, herein an electric motor, provided with an armature shaft 25 on which a pinion 26 is suitably. secured and which meshes with a gear 27 suitably secured to a transverse shaft 28. From, this it will be seen that the transmission shaft 28 carries fixedly secured to its out r end a bevel gear 29, the

latter meshing with two gear members and 31 and acting to drive both of the latter at the same speed, but in opposite directions. The gear members 30 and 31 are mounted to rotate loosely upon a counter shaft 32, but either may be clutched thereto at will to turn the shaft in either direction, and thereby turn a pinion 33 keyed. to said shaft and meshing with a gear 34;, the latter being keyed to a longitudinal driving shaft which is mounted in bearings 36 and provided at each end with suitable worm gearings 36 (see Fig. l) for driving the trucl; wheels secured to the axles Any suitable form of clutching means may be employed but since the particular character of the same is not of great consequence and is not essential to the illustration of my present invention, it will suffice to say that members 30 and 31 are pro vided with clutches 37 and 38 respectively operated by sliding collars 39 and 40 provided respectively with circumferential grooves l1 and 42. These grooves receive yoke-shaped arms :3 and l i, secured to a clutch shifting slide rod mounted to slide in guides 4L6 on the base 1. One end of the slide rod (see Fig. 3) is suitably connected to a hand lever 47, pivoted at 48 upon the frame, so that by moving the hand lever, the gear members 30 and 31 may be clutched, to and unclutched from the counter shaft 32, it being understood, of course, that when one is clutched, the other is unclutched. Preferably the slide rod. and handle are so arranged that they may be moved to any one of the three positions. one of which is e 'ective to drive the truck wheels in one direction, another in the opposite direction, and a third or intermediate position for securing inaction or rest.

During the operation of the machine, the ehanneler is advanced along the track-way, the tools 13 acting to cut a channel groove of increasing depth. For adjustably feed ing the tools with their actuating faces dmvnward upon the standard to adapt them to the increasing depth of the cut or for lifting the tools out of the cut. the feed screw and nut, hereinbefore described. are employed. Referring now to the mechanism for driving the feed screw, a bevel gear member 49 is suitably secured to the feed screw 22. below the bearing 23, which meshes with a bevel gear 50 suitably journaled on the base 1 concentric with the pivotal axis of the standard and preferably iournaled on the trunnion shaft 5. A thrust collar 51 may be provided above the hearing 23 to receive the longitudinal thrust of the feed screw in the one direction, while the hub of the gear 49 receives the thrust of the feed screw in the opposite direction. The gear member 50 may be provided with g j T- fen 52, which may be placed trunnion shaft from one end of the machine to the other, the standard carries with it the bevel gear 50 and spur gear 52, and in order to avoid possible breaking of the teeth of the gears 52, 53 and 54, the two latter gears are preferably secured to the shaft 55 by suitable means, as for example set screws 58 and 59 which permit these gears to be slid out of the way, and after the standard has been moved into place, either gear, as the case may be, is slid back into mesh with the gear 52 and held in place by its set screw. It will now be evident that when the standard is set at one end of the machine, the gear 52 will be driven by the gear 53, and when the standard is at the other end of the machine the gear 52 will be driven by the gear 54.

The shaft. 55 may be driven in any suitable manner from the transmission gear, hereinbefore referred to, but for that purpose said shaft herein has a gear 60 secured. thereto meshing with a gear 61, the latter se cured to a shaft- 62 journaled in the bearings 56 and 57, hereinbefore referred to.. If desired. the shaft 62 may be provided with squared ends 63 and 6-1 to receive a suitable crank (not shown) by means of which shaft 62 and consequently the shaft 55 may be inanually rotated to elevate and depress the sliding frame 10 and the cutting tools 13 carried thereby when there is no power on. Secured to the shaft 62 is a spur gear 62 similar to the gears 53 and 5t, which meshes with a gear 65, the latter (see Fig. 2) being formed on or secured to a sleeve 66, which sleeve is mounted for loose rotation on the driving shaft For turning the sleeve 66 in either direction at will, thereby to raise or lower the tools 13, the sleeve may he provided at opposite ends thereof with suitable clutch devices 67 and 68 which may be clutched to or unclutched from oppositely driven driving members 69 and 70 by devices generally similar to those previously described. The driving member 69 is provided with a spur gear 71 which meshes with a spur gear 72 formed on the truck driving gear member 30, while the tool feeding driving member 70 is provided with a spur gear 73, meshing with a similar gear 74 formed on the truck driving gear 31. From this it follows that the driving members 69 and 70 are constantly driven in opposite directions so that by clutching one or the other to drive the spur gear 65 as described, thetools may be raised or lowered. The clutching devices 67 and 68 are adapted to be actuated by sliding sleeves 75 and 76,

simultaneously shifted in either direction by arms (i and 78 attached to a longitudinally lie shiftable actuating rod 79 adapted to be shifted by a hand lever 80 similar to 'the' end with the sliding frame and at its lower end directly with the tool feeding mechanism on the truck, not only provides a very inconspicuous and exceedingly compact arrangement of tool feeding parts, but leaves the upper portion of the sliding frame and the standard free for the disposition of the motor driven tool reciprocating mechanism. It will further be observed that the feeding mechanism is composed of exceedingly simple parts which may be applied to a channeler of standard form with a minimum of change and that this arrangement of parts provides a mechanism which reduces the overall height of the machine and presents a more compact construction. It will be noted still further, that when the standard is tilted about the axis of the trunnion bar there is no disengagement of the feeding mechanism and no need for manual adjustment of the parts.

lVhile I have in this application specifically described one form which my invention may assume in practice, it will be understood that this form of the same is shown for purposes of illustration and that the invention may be modified and embodied in other forms without departing from its spirit or the scope of the appended claims.
