GEARING.

Patented Oct. 8, 1912.

Application filed July 3, 1912. Serial No. 707,437.

To all whom it may concern:

Be it known that I, ROBERT S. Bnown, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Gearing, of which the following is a specification.

This invention relates to gearing, one of the primary purposes of the invention being to provide effective means whereby a part such as a shaft, can be operated either by power or hand, the construction being such that the two operating means cannot be simultaneously in action. In the drawings accompanying and forming part of the present specification I have shown in detail-one of the several convenient forms of embodiment of the invention which to enable those skilled in the art to practice the same will be set forth fully in the following description. I do not restrict myself, however, to such disclosure; I may depart therefrom in several respects within the scope of the invention defined by the claims following said description.

Referring to said drawings: Figure 1 is a side elevation of a metal working machine involving my invention, and, Fig. 2 is a horizontal section on the line 2-2 of Fig. 1 looking in the direction of the arrow.

Like characters refer to like parts in both views.

My improvements can be incorporated with utility in various kinds of metal working machines, and in fact machines of other types, the invention not being limited in this respect. In Figs. 1 and 2 of the drawings I have shown certain of the members of a multiple-spindle automatic turret-machine such as shown in Letters Patent No. 874,035, of December 17, 1905 granted to George G. Prentice to which reference may be had. A machine such as thatshownin said Letters Patent includes in its organizawhich need not, therefore, be described, as the same in themselves constitute no part of the present invention. I have shown as rising from the bed 5 the bearings 7 and 8 usually integral therewith and tied together by the brace 9. This portion of the showing, however, constitutes the subject matter of a separate copending application filed July 5, 1912, Serial No. 707 ,658. The bear ings 7 and 8 support the spindles 10. It is needless for me to further describe this part of the machine, the same being set forth in detail in said other application.

The bed 5 is shown provided upon one side thereof with a power operable shaft 11 which may receive its motion in any desirable manner, for instance by a train of gears operated from some suitable source of power, the terminal one thereof being shown and being designated by 12. In axial coincidence with the shaft 11 is a second shaft 13 also supported by a bearing on the bed 5, the shaft 13 having a reduced end fitting a socket in the shaft 11. Through clutch means I can connect or disconnect the shaft 11 and the shaft 13, and it will be apparent that when these two shafts are connected the shaft 13 will be rotated provided the shaft 11 is being turned, and when they are dis connected the shaft 13 will be thrown out of action. The clutch means shown for putting the two shafts into and out of operative relation will be hereinafter described. The cam shaft (3 receives its motion from the shaft 13 through suitable means, for instance such as those now to be described. Said shaft 13 at its inner end has fastened thereto a bevel gear 1 1 in mesh with a substantially similar bevel gear 15 and the transverse shaft 16 supported by suitable bearings upon the head end of the bed 5. Said shaft 16 between its ends is equipped with a worm 17 in mesh with the worm gear 18 fastened to the cam shaft 6. It will, therefore, be clear that when the shaft 16 is turned the cam shaft 6 will be operated a similar extent. The said shaft 16 as already described is adapted to be operated by power. It may also as will hereinafter appear be operated by hand, and hand operating means are such as to adjust the said shaft 6, so that parts which receive their motion therefrom can be correspond ingly adjusted.

The bevel gear 15 is shown located at one r pa i n lu c v member ll. be retracte o as will hereinafter be set forth to be manually operated and which through clutch V mechanism as will hereinafter appear is.

adapted to. turn the shaft 21 and therefore through the connections already described, adjust the cam shaft 6. The bed 5 is equipped with a suitable bearing for sustaining the shaft 22 and said shaft fits a socket in the coiiperating shaft 2,1, Owing to the described connection between the two sets of shafts they are effectively supported at their ends presenting in effect, except so far as their motion is concerned, continuous Shafts.

Splined to the, shaft 11 for rotative movement therewith and longitudinal movement thereon, is a clutch member 23 co'ciperative with the clutch member 2a fastened to the shaft 13. It will be clear that when the clutch member 23 engages the clutch mem-.

her 241, thetvvo shafts 11 and 13 will be operatively connected together, so that if the shaft 11 be turned, the cam Shaft 6 through the intermediate parts already described will be otated by PQWQ Sp l d o t e af 21 fo r at on h r the clutch, member 26 fastened t0 the shaft 22. It will be evident that when, the clutch members 25 and 26 are connected together and that when the shaft 22 is turned by hand, the cam shaft 6 through, the intervening connections already set forth, can be rofatedtions of which have already been described are so related that the shiftable members thereof cannot be simultaneously advanced. Thatis to say when the clutch member 23 is ad anced he c tch member 25 willbe rerac ed nd ice versa, so at h alv of the clutches cannot be engaged at the,

same time,

which are provided with pins or studs entering peripheral grooves or channels in said respective clutch halves after the well-known. manner in clutch shifting devices. The two forks 28 and29 andthe shaft, are so related that when said shaft is rocked in. one

direction one clutch member such as the member 23 will be advanced to engage thecompanion clutch member 24, whilethe com The two. clutches. the halves or secthereby disengage it from the cotiperating clutch member 26. To facilitate the operation of the clutch member shifting devices one of the forks as that denoted by 29 may be provided with an upwardly extending portion 30 terminating in a handle 31 which can be grasped by the attendant to simulta 'neously operate the clutch members 23 and v 25. It will be assumed that the clutch member 23 is disengaged from the clutch 1ne1nher 2 1 and that the clutch members 25 and 26 are in engagement so. that the vcam shaft 6 can be operated by hand but not by power, notwithstanding the fact that the shaft 11 may be rotating. To facilitate the operation L of the shaft 22 the hand crank 32 may be provided, said hand crank being adapted through suitable interposed gearing to transfer its effect to the shaft 22 for rotating the same when occasion therefor isrequired.

.The. said hand crank v32 is fastened to the shaft 33. rotatively supported by the arm 3% ion the bearing for the shaft 22. Fastened to said shaft 33 is a spiral gear .35 in mesh With a Similar spiral gear 36on theshaft 22. Therefore, when the clutch members 25 and V 26- are engaged the shaft 6 can be manually adjusted by turning the hand crank 32, the i effect of the latter being applied to the shaft .22 through the interposed described gears F and the motion of said shaft 22 being transferred to the cam shaft through the agency ,of theconnections already described.

with and for longitudinal movement there- Q .1 s the clutc memb r 25 co perative with What I claim is:
