AUTOMATIC STOPPING AND LOCKING DEVICE FOR BRUSH-MACHINES.

Application lecl September 8, 1914.

To all lwhom t may concern.'

Be it known that I, TIEN RY ALBERT GLssoN, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State Vof Ohio7 have invented certain new and useful Improvements in Automatic Stoppin and Lockingq Devices for Brush- Machines, of which the following is a full, clear, and exact description.

This invention relates to automatic stopping, and locking devices for brush machines.

The object of the invention is to provide automatic means on brush machines for stopping the drilling and filling tools at a certain predetermined time, and stopping the'movement of the work supporting members at a predetermined time, in order to keep all the actuating mechanism in proper timed relation, and in position for the beginning of another cycle of operation.

In brush machines such as illustrated and described in my co-pending application Serial Number 832,659 filed April 17, 1914, it is necessary to provide automatic stopping means for stopping the drilling and filling tools in proper timed relation one with the other and with relation to the operating mechanism, in order to avoid the breaking of either of the tools by the movement of the work supporting members while the drilling and filling tools are engaging same. Furthermore, the different actuating parts of the machine must not travel beyond their proper position after the brush back has been completely bored and filled, owing to the difficulty in bringing` the actuating parts of the machine back again to their proper starting position.

Another object of this invention is to pro vide an automatic stop for all the actuating mechanism of the brush machine making it possible to stop the different actuating parts of the machine at any desired point in their cycle of operation,

In the machine to which this device is applied, a reciprocating and rotating master drum is employed which is provided with a series of actuating bars mounted thereon which operate the mechanism for moving the work supportingl membersby engaging same and pushing said mechanism to one side or the other as desired. In a complete cycle of rotation of said drum one brush back is bored and filled, and if there Specification of Letters Patent.

are ninety holes in the brush back, ninety actuating bars have been used in the operation, and in order to bring the first actuating bar back to its starting position the drum must continue to rotate after the brush back has been completed, provided there are, say 100 bars on the drum. But, however, the drilling and filling tools must stop in their starting position immediately upon the finishing of the boring and filling of the brush back.

Therefore, it is necessary to provide an automatic stopping device for the machine which will stop the drilling and filling tools at the proper time, but will allow the drum to rotate further a certain distance before stopping, in order to complete its cycle of operation.

My invention consists in certain combinations of parts and details of construction as will be described in the following specification and pointed out in the appended claims.

The brush machine to which this invention is applied employs operating` mechanism for the work supporting members and also means for the boring mechanism, said means however, preferably deriving their power from the same source. The operation of the work supporting members is stopped by independent means, coperating` with the driving means of the machine after the boring mechanism has been stopped. This is necessary in order to provide for brush backs of various sizes having more or less holes or tufts.

In the drawings:

Referring more particularly to the drawings; 1 :indicates the fbase 'of a brush ma- .ehine and 2 the legs thereof. The top 4 y'of the frame Aconstitutes the ibase upon which the tufting and drilling `mechanism `operates, While that partof thelftop indicated iat :5 .constitutes the lbase upon which the Work supporting imembers 6 operate.

The 'ivorlr supporting members 6 and their operation-'are fully explained and illustrated :in my aforesaidco-pending application, and it is not deemed necessary to describe :them :in detail ahere.

L1-reciprocating and rotating master drum 7 is mounted on reciprocating :bearings or 'rollers 8 which opera-te von tracks 9.

Actuaitir-g vbars 10 Aare mounted in :slots faround the periphery of thedrum 7 and con trol the movement of actuating mechanism (shown in a general Way at 11) alll of which ift :is not thought necessary to illustrate `in this application inasmuch as a full detailed description thereof is found in my aforesaid copending application and it forms subeet matter for the said application.

. rx'llhe mechanism 11 operates the Work supporting :members in a number of vdifferent directions relative to lthe drilling and filling tools 12. Tfhemaster drum 7 is mounted'on the sleeve 13. rlhe sleeve 13 is mounted on the dri-ve shaft 14 which is driven by the pulley 115 which in turn yis driven by a belt or any 4other sui-table means. The shaft 14 iliasa -pulley 17 mounted at the opposite endV from that of rthe pulley and a belt 1S connects same With the fly Wheel 19 thereby driving said fly Wheel.

"The ffly wheel 19 is mounted on a sleeve 21 near the front of the vmachine and the sleeve in ytuJn is mounted on the sha-ft 2O (Fig. 2) said sleeve bei-ng mounted in a fbearing 22 saidbearing being properly 'mounted on one of the legs 2 ofthe frame of the machine. The shafty 2O is mounted in a suitable bearing 23 in one of the legs 2 of the frame of the machine -at the opposite end from that upon `which the fly Wheel is mounted.

Mounted tight upon the sh aft is a 'bevel gear 24C which vis provided with clutch lteeth 25 for engagement with a clutch memberQG which is 4provided with the recesses 27 ofthe clutch for interlockirg With Ithe clutch teeth 25 ,of the vgear 2l.

member 24.

Thus, the shaft 29 actuates the boring mech-l anism bymeans of mechanism, (not shown) said mechanism formingno part of this invention and 'being Well Aknown in the art, and therefore not considered necessaryv to illustrate.

`The clutch member 26 is provided With an connected Aat its upperencl 'with .a connecting :link #L0 -Which in turn is connected to an arm l-1 which is mounted rigidly on the shaft Ll2 said shaft@ beingY mounted in 'bearings 43 mount-ed on lthe frame o'f the machine.

Thus it is seen that when the handledi israised the dog 47 is also lifted out rof engagement- -With the dia-ller disk t8 which dial forms a timing device for stoppingthe mach-ine.

The KAbevel gear '36 meshes lwith bevel gear 54 which is rigidly vmounted 'on a shaft 56 said shaftibein-g mounted yin Vsuitable bearings on the frame of "the machine, and bevel gear 58 mounted at the :other end of said shaft 56 meshing with fa bevel gear 59 which is mounted on the sleeve 13 'Which sleeve operates reciprocating and rotating mechanism for the master drum t7. i

Mounted Aon'the shaft '5.6 l 'provide -a Worm Wheel 'G0 which meshesavith'the Worm Wheel 61 tightly mountedon 4the' stud or shaft 62. This Worm Wheel y6'1 carries ,the dials or disks 48 and 49 the former being in `this ease adjustable circumferentially on the shaft 62 by means of the slot 64 and cap screw 65.

In order to stop the reciprocating movement of the boring mechanism I pro-vide the connecting rod 66 (Fig. 3) which connects the lever operating rocker arm 34 with the slidalole extension 67` on the sliding member 68 having an extension 69 which engages the recess 7 0 in the driving cam 71, which driving cam is mounted onA the shaft 20. The

sliding member 68 is mounted in the bearing 72 and has a pin 7 3 extending laterally therefrom and passing through the slots 74 in the bearing 72. Thus when the rocker arm 134 is in the position shown in Fig. 3 the extension 69 is locking the driving cam 71 against rotation.

In order to cause the fly wheel 19 to drive the mechanism of the machine I provide a clutch which will now be described. The fly-wheel is provided with the hub 75 which rotates on a bushing or sleeve 76 Which is keyed by means of the key 77 to the sleeve 21 on the shaft 20. This sleeve 76 is provided with a paw] 78 (Figs. 2 and 5) which pavvl is rigidly mounted on the key 79, said key being semicircular in cross section as shown in Fig. 8. The key 79 rests normally in a semicircular slot in the sleeve or bushing 76 and is mounted in the lugs 80 on said sleeve76 as best shown in Figs. 2 and 5. The pawl 78 is provided with a compression spring 81 mounted at the end thereof, said compression spring passing into a recess 82 in the sleeve or bushing 76 and tending to force said pawl to its outermost position shown in dotted lines in Fig. 5. A series of slots 83 are provided in the hub 75 of the fly wheel, each slot being provided with a horizontal steel key or block 84 for engagement with the key 79. Now when the pawl 78 is allowedto reach its dotted line position shown in Fig. 5 the half round key 79 will assume the position shown in Fig. 7 as soon as one of the slots 83 in the hub 75 of the fly wheel has reached the proper position thus causing the iy wheel to drive the bushing 76 and in turn drive all the other mechanism connected 'therewith.

The pawl 78 is normally held in the position shown in Fig. 5 by the pin 85. This pin 85 is mounted in a bracket 86 (Fig. 3) the bracket being suitably mounted on the frame of the machine and being provided with the slot 87 through which the connection or pin 88 extends from the sliding pin 85. The pin 88 is in turn fastened to an arm 89 which in turn is mounted on a rocker arm 90 and is reciprocated thereby. This rocker arm 90 is rigidly fastened to the shaft 39 as shown in Fig. 1, and is provided with two extending lugs 91 projecting on each side of the operating rocker arm 34 and allowing a considerable amount of play for the rocker arm 34 to operate there-between. To adjust this amount of play I provide the set screw 93 which may be adjusted to increase or decrease the amount of play as desired. The bracket 86 which carries the pin 85 also carries the pin 94 below the pin 85. This pin is also slidably mounted in the arm v86 and operated by the moving bracket 89 in a similar manner. It is the purpose of this pin to form a stop for the sleeve or bushing 76 which is provided with the flange 95 having the eX- tension 96 for engagement with said pin 94. Thus it is seen that the pin 94 will prevent rotating so far as to allow the pawl 78 to travel past the stopping pin 85.

The operation of the stopping device is as follows:

The fly wheel being driven constantly, is

.engaged and disengaged by means of the semicircular key 79. When the handle 44 is raised the operating rocker arm 34 is moved inwardly and immediately causes the members of the clutch A to engage each other, the teeth always being in proper relation due to the stopping mechanism for the cam 71 includingthe pin 69. The shaft 20 begins to rotate immediately upon the engagement of the clutch A, and clutch A also operates the bevel gear 36 which in turn operates the bevel gear 54, thereby operating the shaft 56. The shaft 56, it is readily seen, operates the master drum by means of the bevel gear 58. The worm 60 being mounted on the shaft 56 operates the worm wheel 61 and is properly gaged so as to move the worm wheel 61 one tooth circumferentially while it is making one revolution. Thus the worm wheel 61 is provided wit-h as many teeth as there are slots for the bars 10 in the master drum. The disks 0r dials 48 and 49 are mounted on the worm wheel. 61 and rotate therewith, they being first adjusted to bring their cut away portion into engagement with the dogs 47 and 51 at the proper predetermined time. Thus as the worm 60 rotates the disks also rotate; the dogs, of course havel been thrown out of engagement by means of lifting the handle 44 to start the machine. As the handle 44 is lifted the operating rocker arm 34-is tilted or rocked so as to throw the clutch A into engagement which at the same time pulls the crank arm 90 which is tightly fastened to the shaft 39 over therewith, which in turn pulls the bracket 98 therewith., thereby pulling the pins 85 and 94 out of engagement with the pawl 78 and the lug and extension 96, thereby allowing the pawl 7 8 to operate the half round key in order to cause the fly wheel to drive the clutch mechanism. This it is readily seen immediately starts the entire machine.

Now when the master drum has rotated far enough so as to have brought al1 of the FID operating bars into operative engagement rwith .the proper mechanism, the :pawl 4?? will fall to its 'lowermost position from 'the .cut edge lOl on :the fdial, n'herebyrocking the .39 :owing A.to the `tacit that :the enga ging lugs 91 von the crank `90 have enough play vthererbetxveen `to allow @the operating rocker arm 34 to return Without eil'ectingthe anove- =ment fof the :crank farm f90. Y

It `will 'be -noted vthat .the pin `85 will force the 4pawl 78 to :the :position shown in lfull lines in IFig. '5,

l.thereby turn-ing the hali' 4round key .to 'the position Vshown i-n Fig. '6 and allowing the ffly Wheel to run Jfreely over .the hub .of `the bushing '78. l

It :is believed `that the operation of the -device `can readily lbe understood from the foregoing description. Certain modi-tications of myinvention .might Ibe Ymade With-Y out departing from its spirit and Cscope and I do .not wish to fbe confined to the `exact de- Stails shown.
