MACHINE FOR DIPPING HATS.

SPECIFICATION forming part 0f` Letters Patent No. 540,802, dated June 11, 1895.

Application led October 8, 1894.

To all whom t may concern:

Be itknown that I, CHARLES S. PECK, a citizen of the United States, residingat Danbury, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Machines for Dipping Hats; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledI in the art to which itappertains to make and use the same.

My invention has for its object to produce a machine for dipping hat bodies upon the cone, every movement. of which shall be automatic, which will lower the body into the tank and will also raise it therefrom with a retarded movement, that is to say, when the body is descending or sinking in the tank the movement will be fastest at the start and will grow slower to the end of the movement so that there shall be no danger whatever of forcing air within the body through it Violently so as to rupture or injure the body, and

the movement ofthe bo'dy in rising will also be fastest at the start and will grow slower to the end of the movement, the effect being to compact the fur in the body together sufficiently to permit it to be readily removed from the cone, andalso to prevent splashing of Waterfrom the tank, as necessarily results it the last portion of theupward movement of the cone and body is made too rapidly, thus making the operation of the machine fastest when no injury can result from rapid movement and relative-ly slow at the times when it is possible for injury to the bodies to result from rapid movement, and for the water in the tank to be splashed out, which is a serious inconvenience in use.

My invention has for its object furthermore to provide an adjustment which will determine the length of time'which the body shallremain submerged, it being of course understood that certain grades of bodies in order to get the best results require to remainsubmerged much longer than other grades of bodies do. The operation of my novel machine issuch that if it is desired to have the body begin to rise the instant that the submersion is completed the machine may be adjusted to produce that result or it may beadsefni No. 525.238. (nmada-.i

justed seas to permit the body to remain submerged for any required length of time before the upward movement commences.

My invention furthermore relates to vari'- ous novel mechanisms and arrangements and combinations of elements for producing the desired results which will hereinafter be fully described and thenspecifically pointed outin the claims.

4ln the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of the machine complete; Fig. 2, a sectionon the line @c in Fig. 1,1ooking toward the left; Fig. '3, a section on an enlarged scale cn the line o u iii Fig. 4, looking toward the left; Fig. 4, a section on theline w w, indicated in Figs. 1 and 5, looking up in Fig. l and toward the left in Fig. 5; Fig. 5, a section of the main shaft on the line 0,0 in Fig. 4, looking toward the' right, the parts being shown out 'of their' actual position, but corresponding to the position in which they appear in Fig. 4, the engaging-lug appearing in full lines at the top ot` its normal position relative to the other parts and in dotted lines at the bottom in the position it occupies at the instant the hat-body is wholly submerged in the tank and the lowering mechanism is stopped; Fig. 6, a section of the main shaft, likewise on the line o o in Fig. 4, but showing the parts at their normal position'-that is, a position in which the machine is ready to be started to lower a hat-body; Fig. 7, a similar view, the engaginglug having moved to the position it occupies when in engagement with the crown-teeth on the large gearwheel; Fig. 8, a section on the line p p ,in Fig. 1, the main shaft and locking-cam being in end elevation, as seen from the left in said ligure; Fig. 9, a section on the line y y in Fig. 1, looking towardthe right; Fig. 10, a similar view on theline z z in Fig. 1, said views showing, respectively, the positions of the eccentrically-pivoted elliptical raising and lowering gears at the instant the lowering operation commences; Fig. 11,a detail end eleva- IOC) 3 to 12, inclusive, are all on the same scale, which is an enlargement of the scale in Figs. 1 and 2.

1 denotes framework which may be of any suitable design and is ordinarily adapted for attachment to the ceiling or to overhead beams. It may however, be supported by standards if preferred.

Power is applied to drive the machine by a belt 2 running over a cone pulley 3 and passing through a belt shifter 4 of ordinary construction. The shifting lever 5 is provided with a latch G which is adapted to engage notches in a plate 7 to lock the belt shifter, and with it the belt in any required position on the cone pulley. By the use of a cone pulley and belt shifter I am enabled to increase or decrease the speed of the machine at any time by a slight movement of the lever in either direction as may be required.

Belt pulley 3 is carried by a shaft 8 which is the driving shaftof the machine. This shaft is suitably journaled on the frame and carries in addition to the cone pulley a pinion 9 and a spiral gear 10.

11 denotes the main shaft which is suitably journaled on the frame above the driving shaft. i

At the right end of the machine as seen in Fig. 1 and below the main shaft is a shaft 12 which I term the secondary shaft.

At the right end of the main shaft as seen in Fig. 1 is journaled the dipping wheel 13, in the present instance a sprocket wheel, over which a sprocket chain 14 passes, one end ot' said chain being secured to the wheel as indi catedin Fig. 1. A rope or cord inayof course be substituted if preferred. of the sprocket chain is attached the usual carrier 15, upon which the cones with hat bodies thereon are placed for submersion in the tank, which is denoted by 1G.

17 denotes a large gear wheel having a hub 18 which turns freely on the main shaft. This gear wheel meshes with pinion 9 and is always turning when the machine is in use.

The inner face of gear wheel 17 is provided with crown teeth 19V which are adapted to be engaged by a lug 2O on a sliding block 21 carried by a plate 22 which is rigidly secured to the main shaft. I have shown this block as moving on ways at the sides of a recess 23 in the plate and as moved forward by a spring 24 sockcted in plate 22 below the block. See Fig. 7. Upon the outer face of the block isa rigid latch 25 which is adapted to engage a lever 26 pivoted to an arm 27 depending from a block 28 which is rigidly secured to or cast integral with a bracket 20 the latter being rigidly bolted to the frame as clearly shown in Fig. 1. The shape of this lever is clearly shown in Figs. 5,6 and 7, which see in connection with Fig. 1. The special outline of the lever is of course not ofthe essence of my invention, the essential requirements being a surface 30 for engagement by latch 25, a notch 31 adapted to engagea pin 32 projecting out At the other end ward from the block, and a notch and a surface 34 both of which are adapted to be engaged bya stump 35 which lies in a slot 3G in block 28, said stump projecting outward from a block 37 which is adapted to slide in a recess in block 28, said block 37 being normally held at the raised position by a spring 38 socketed in block 28 below block 37.

39 denotes a rod connected to block 37 and passing down within spring 38 and through block 28, to the lower end of which an operating cord 40 is attached. See Figs. 1 and 2. 4l is a cross pin in rod 39 which engages the underside of block 28 and limits the upward movement of the rod.

As already stated the large gear wheel is always moving when the machine is in use. Vhen it is desired to dip a hat body the operator simply pulls down upon operating cord 40 and from this instant the operation of the machine in lowering the hat into the tank,

holding it submerged for the length of time that has been determined upon and raising it again out of the tank is automatic.

The normal position of the parts just de scribed is shown in Fig. 6.

When the operator pulls down upon the operating cord he moves block 37 down to the position shown in Fig. 7.- This permits spring 24 to move sliding block 21 which carries the engaging lug outward and moves lever 2G to the position in which it is shown, that is to say, stump 35 will have moved downward far enough so that the bearing surface which normally rests against the stump will pass fort ward over the stump and the stump itself will lic in notch This movement of sliding block 21 carries the engaging lug outward far enough to place it uin engagement with crown teeth 19 on the large gear wheel. The actual engaged position of the lug with the crown teeth is not shown in the drawings but will be readily understood from Figs. 1 and 2, more especially Fig. l, in which the engaging lug is shown as registering with a space between two crown teeth from which position it would simply move forward toward the point of view to be in engagement with the teeth. The instant the lug becomes engaged with the crown teeth motion is imparted to plate 22,

and a halt' revolution is imparted tothe main shaft which lowers the body into the tank as will presently be more lfully explained. At the instant the body is at the lowered position in the tank the engaging lng and sliding block 2l will be at the position shown in dotted lines at the bottom in Fig. 5, that is to say, latch 25 will have engaged a cam 42 on a sliding collar 43 on a rod 44, the respective ends of which are rigidly secured tothe frame as indicated in Fig. 1, the downward move- TIG IIS

ment of collar 43 on the rod being limited by I a pin 55. The eect of the engagement ot' latch 25 with cam 42 will be to force the latch and with it the sliding block and engaging lug backward as clearly indicated in dotted lines in Fig. 5 and will move said lug out of 'engagement with the crownteeth on the large gear wheel thus instantly stopping the rotation of the main shaft, inwhich position all of the parts will remain, the hat body being wholly submerged in the tank, until lug 2O is again placed in engagement with the crown teeth as I shall presentlyexplain. In order to insure that the main shaft will be locked in position instantly when it has completed each half revolution I provide a plate at the end of the main shaft, see Fig. 8 and at the left in Fig. 1, which is provided on opposite 'sides with notches 46 Yadapted to be engaged by a roller 47 carried by an arm 48 the lower end of which is in the present instance pivoted on the driving shaft. See Fig. 1. The roller is held in engagement with the periphery of the cam and is forced into the notches by a spring 49 carried by a threaded rod 50 which is adjustable in a bracket 51 itself rigidly secured to the arm. See Figs. 1 and 8. The tension of the spring and consequent'ly the pressure of the roller upon the cam are adjusted by turning the rod in or out asmay be required and locking it inpof sition after adjustment by a check nut 52.

53 denotes a rod the respective ends of which are rigidly secured to the frame and 54 a block adapted to slide thereou,.the downward movement of the block upon the rod being limited by a collar 56.

57 denotes a screw shaft the ends of which are journaled in hubs 58 themselves rigidly secured tothe frame. Y Y

59 is a collar on the screw shaft which bears against the upper hub to prevent upwardv movement of the shaft and 60 is a spiral gear lon said shaft which rests upon the lower hub in Figs. 2 and 3. In the drawings I have shown the spring as connected to the lower end of theleverand as provided with acurved plate which bears against the screw shaft below the threaded portion as is clearly shown -in Fig. 2'.

66, see Figs. 2 and 3, denotes a cam on a collar 67 rigidly secured to the main shaft. The operative position of this cam is indicated in dotted lines in Fig. 3 and'its operation will be clearly understood from this figure. Vhen latch 25 is in the position shown in Fig. 6 the cam is in the position shown in full lines in Fig. 3. When the cam has completed a vhalf revolution and is in the position indicated by dotted lines at the bottom inV Fig. 5 the cam willbe in the position shown in dottedlines in Fig 3 and will force the lever inward and will place the threaded block in engagement 'with the thread of the screw shaft in which position the parts will remain, owing to the ystopping of the rotation of the main shaft as already described until the main shaft starts again and the cam passes outof engagement with the lever, the screw shaft however, being continuously in rotation. It is obvious that when the threaded block is in engagement with the screw shaft the rotation of said shaft, in the direction indicated by the arrow in Fig. 3, will raise block 54 on rod v53 by which it is carried.

68 denotes a lug projecting outward from block 54 and which is engaged by a rod 69, a

Vportion of which is threaded. This rod is provided at its upper end with a collar 70, to prevent it from being wholly withdrawn from the lug, at its lower end with a hand wheel 71 for convenience in operation and between the collar and hand wheel with collars 72 both of which are rigidly secured to the rod and which retain betweenthem a collar73, not secured to the rod, which carries an arm 74 the outer end of which is bifurcated, the branches being curved to partially inclose rod 44. It is of course obvious that rotation of rod 69 will raise or lower said rod through the engagement of the thread thereon-with lug 68 and will consequently raise collars 72 and 73 and arm 74 relatively to block 54.

The operation of this portion of the Inachine isas follows: When. the rotation of the main shaft causes cam 66 to engage lever 62 43 on said rod and will raise cam 42 on said collar out of engagement with latch 25. See Figs. 4 and 5. This will permit lug 2O on sliding block 2l to again engage crown teeth 19 on the large gear wheel which instantly communicate motion to the main shaft. The instant the main shaft com mencesv to move again cam 66 ou said shaft will pass out of engagement withrlever 62 and spring 64 will at once move the threaded blockA out of engagement with the screw shaft. This of course releases block 54 and permits it to drop down on rod 53 until it is stopped by collar 56.

In order to prevent positive engagement of cam 66 with lever 62, which may lead to breakage of parts should the thread upon the block ICO IIO

fail to engage the thread of the screw shaft,

tact they will engage an instant later owing to the rotation of the screw shaft and the yielding of spring 75.

It will be understood from the description already given that until cam 42 on sliding collar 43 is raised suiiiciently to permit latch 25 to resume its normal position and lug 2O to engage the crown teeth on the large gear wheel the hat body which has been lowered into the tank will remain submerged. The length of time that the body remains submerged will depend of course on the adjustment of arm 74 which is carried by rod 69, it being apparent that if said arm is raised high enough so that it will engage sliding collar 43 an instant after latch 25 is moved back by cam 42 and the engaging cam thrown out of engagement with the crown teeth, the upward movement o f the hat body will commence immediately, and that just as long a period of submersion as maybe required can be obtained by rotating rod (it) and moving arm 74 downward, it being of course understood that collars 72 rotate with the rod so that the rod turns freely in collar 73 which Carries the arm.

The rotation of the maintshaft and consequently the rasing of the hat body from the tank will continue until the second half revolution of the main shaft is completed and latch 25 has engaged lever 26 and been moved backward thereby carrying the engaging lug out of engagement with the crown teeth, this position being clearly shown in Fig. 6 which seein connection with Fig.1. It will be noticed in Figs. (3 and 7 that notch "33 in lever 2G and stump 35 are both slightly rounded so that the instant latch 25 has passed off from lever 26, that is, the instant the partsmove out of the position shown in Fig. 7, spring 38 will raise block 37 and stump 35 will pass out of notch 33 and will move the lever back from the position shown in Fig. 7 to that shown in Fig. 6 the backward movement of the lever being stopped by pin 32, as clearly shown in Fig. 6, the parts remaining in this position until the dipping mechanism is started again by another pull upon the operating cord. As the second half revolution of the main shaft is completed latch 25 will pass on to lever 26 and will be forced inward thereby mov` ing the engaging lug out of engagement with the crown teeth and stopping the machine the instant the revolution has been completed and the hat body is at the raised position, the parts being locked in this position as already stated by the engagement of roller 47 with one of the notches in cam 45 as clearly shown in Fig.

Turning now to Figs. 9, l0, 1l and 12 in connection with Fig. 1, I will explain the operation of the dipping mechanism and of the mechanism for retarding the movement of the hat body when it is sinking in the tank and for retarding the movement when the body is being raised from the tank. By the term retarded I mean that the movement in `the position shown in Fig. l1.

both directions commences at the maximum speed and gradually grows slower.

The dipping mechanism is clearly illustrated in detail in Figs. 11 and l2.

It will of course be understood that motion is transmitted from main shaft 11 to shaft 12 which I have termed the secondary shaft. So far as the dipping mechanism itself is conconcerned this motion might be transmitted in any suitable manner as by a pinion on each shaft meshing with a pinion of equal size on the other shaft. The mechanism which I employ and which produces a gradually retarded motion when the body is moving downward and also a gradually retarded movement when the body is moving upward will be described later on.

76 denotes a gear and 77 a slightly smaller gear both of which together with sprocket wheel 13 are keyed to a sleeve 78 which turns freely on the main shaft, said sleeve being held in position thereon bya screw79 engaging the end of the shaft.

8O denotes a mutilated gear keyed to shaft 12 the toothed portion of which engages gear 76, and S1 a smaller mutilated gear also keyed to shaft 12 the toothed portion of which engages an idle gear 82 which is journaled on a bracket S3 rigidly secured to the frame, idle gear 82 also engaging gear 77 ou sleeve 7S. It should be understood that gears 7G and 77 and the sprocket wheel move together and that gears SO and 81 move together, the idle gear engaging gear 77 and the mutilated gear 3l.

The operation of this portion of my inven tion is as follows: So far as this mechanism is concerned shaft 12 is the driving shaft. Suppose now that a hat body is placed upon the carrier for dipping, the carrier being in the position shown in Fig. 1, and that the operator starts the dipping mechanism bya pull upon operating cord 40. The gearing of the dipping mechanism will at this moment be in motion is communicated to shaft 12 the toothed portion of mutilated gear 81 will begin to rotate in the direction ot' the arrow and will engage idle gear 82 which in turn will engage gear 77 upon sleeve 78 and will cause the sprocket wheel to turn from back to front as the parts appear in Figs. 1 and 12. This i will lower the hat body in the tank, the downment of the main shaft again commences, for

the purpose of raising the body from the tank,

The instant.

IIO

'rier and the body thereon out of the tank.

the toothed portion of mutilated gea-r 80 will pass into engagement with gear 76. This position is not show-n in the drawings, Fig. 11l

showing a position in which the toothed portion of mutilated gear 80 is just passing outJ of engagement with gear 76. It is believed however, that this position will be clearly understood from Fig. 11 in connection with the description. The toothed portion of mutilated gear 81 will now be wholly out of engagement with idle gear 82, and gear 76. The sleeve and the sprocket wheel will now receive motion directly from shaft 12 through the engagement of the toothed portion of mutilated gear 8O with gear 76 and. its motion will of course be in the reverso direction from that indicated b y the arrows so that the sprocket wheel will Wind` up the chain and lift the car- It will of course be understood that during this movement the idle gear will simply' be carried by gear 77 but will perform no function whatever, the operative function of the idle gear being to receive motion from the toothed portion of mutilated gear 8l and to communicate motion to gear 77 in lowering hat bodies into the tank.

Turning now to Figs. 9 and 10 in connection with Fig. 1, Iwill explain the'operation hat body is descending and for again retarding the movement when it is rising from the tank.

84,*see Fig. 10, denotes a mutilated eccentri'cally mounted elliptical gear keyed to shaft 11 and 85 an eccentrically mounted elliptical gear keyed to shaft 12 which meshes therewith. These are the gears which communicate motion from the main shaft to shaft 12 to produce the downward movement of the hat bodies. The ellipticity of gears 84C and 85 and also of gears S7 and 8S, presently to be` described, is so slight as not to be observable in a ligure of 'the size of those shown. It is moreover` a necessity of construction and is merely a matter of mechanical skill in laying out the gears. No attempt therefore has been made to indicate ellipticity in the drawings. Both gears are provided with reinforces 86 for the purpose of strengthening the tooth which is engaged by the other gear at the beginning of each lowering operation.

It will be noticed that at the starting point the long radius of the driving gear registers with the short radius of the driven gear and that as the movement proceeds the operative in the tank with a constantly retarded move- Aportion of gear 88.

This constantly retarded move- `eccentricallymounted elliptical gear keyed to the main shaft and 88 another eccentrically mounted elliptical gear keyed to shaft l2 both of these gears being provided with reinforcesS the-same as gears Stand 85. At the beginning of the downward movement of the carrier and hat bodygears 87 andl 88 will be in the position shown in Fig. 9, the toothed portion of mutilated gear 87 having passed out of engagement with the toothed At the instant that the movement of gears S4 and S5, just described, is completed gears .87 and 88 will be at the same position relatively' to each other that gears 8i and 85 are in Fig. 10, that is to say, the engaging teeth of said gears will be just in position to engage the instant that the movement of the main shaftcommences again, and gears 84 and 85 will be in the same position relatively to each other that gears 87 and 8S are in Fig. 9, that is to say, the toothed portion of mutilated gear 84 will have passed out of engagement with gear 85. s

It will be understood from the above that during the first half. revolution of the main shaft gears 87 and S8 are inoperative and gears 84 and 85 are operative in communicating motion from the main shaft to shaft 12. It follows therefore that duringthe second half revolution of the main shaft gears 84 and- 85 will be inoperative and gears 87 and 88 will be operative. The instant that mutilated gear 87 begins to communicate motion to gear 88 the long radius of the driving gear will regt ister with the short radius of the driven gear and as the movement proceeds the operative radius of the driving gear will constantly vgrow shorter and the'operative radius ofthe driven gear will constantly growlonger so that the motion of shaft 12 will be constantly retarded which motion will be communicatedl through the mechanism just described to the sprocket Wheel and will raise the hat body from the tank with a constantly retarded motion just as it is lowered by the reverse movement with a constantly retarded motion that is to say, the movement of the hat bodies while being lowered into the tank and while being raised therefrom is made as fast as is practicable at the start but is constantly retarded to the end of the movement.

By imparting to the carrier a rapidmovement when no harm can result therefrom I give to the machine the greatest possible capacity for work. By retarding the' downward movement of the carrier `I do away with all danger of forcing the air within the lbody through it so violently as to injure it to the slightest extent and by retarding the upward IIO movement of the carrier I avoid all danger of splashing or throwing water out of the tank.

The operation of the machine as a whole has been so fully described in the description of the several mechanisms as hardly to require further description. It is suiieient to say that after each raising movement the machine is automatically stopped by the engagement of latch 25 with lever26 and the engagement of roller 47 with one of the notches on cam 45 exactly in position ready for starting again. All the operator is required to do to dip a hat body is to place a cone with abody thereon on the carrier and pull the operating cord, the entire operation ot' the machine being automatic. When the operator pulls upon cord 40 lever 26 is released so that spring 24- will force sliding block 2l forwardand will place lug 20 in engagement with the crown teeth on the large gear wheel. This imparts movement to thc main shaft and lowers the body on the carrier into the faul; with a grad ually retarded movement. At theinstant the hat body has become fully submerged in the tank latch 25 will engage cam 42 on sliding collar 43 which will move lug 20 out of engagement. with the crown teeth on the large gear wheel and will stop the operating mechanism, the hat body remaining submerged iny the tank until collar 43 carrying cam 42 `shall be automatically lifted permitting spring 24 to throw the latch forward again and place lug 20 in engagement with the crown teeth on the large gear wheel. Motion is thus automaticallyrcommunicated to the main shaft again and the body is raised from the tank with a constantly retarded movement stopping instantly by the engagement of latch 25 with'lever 26 when the carrier has reached the raised position.

Having thus described my invention, I claim- 1. In combination a carrier for hat bodies, a dipping wheel from which the carrier is suspended, mechanism for rotating the dipping wheel in opposite directions with a retarded movement so that in raising and lowering a hat body the movement. grows slower from start to finish thereby preventing air from being forced through the body inthe downward movement and preventing splashing of water in the upward movement and mechanism' for retaining the carrier at the lowered position for any desired length of time.- v

2. In combination gears 76 and 77and the dipping wheel moving together, idle gear 82 meshing with gear 77, and mutilated driving gears SO and S1, the toothed portion of said mutilated gear SO engaging gear 76 and the toothed portion of said mutilated gear 81 engaging idle gear 82 whereby when mutilated gear 81 and `idle gear 82 are in engagement the latter communicates motion to gear 77 and the dipping wheel and when mutilated gear SO engages gear 76 said gear and the dipping wheel are rotated in the opposite direction.

3. In combination shafts 11 and 12, suitable means for communicating motion from one shaft to the other, sleeve 78 journaled on shaft 11 and carrying gears 76 and 77 and the dipping wheel, gear S2 meshing with gear 77, and mutilated driving gears 80 and 81 car,- ried by shaft 12, the toothed portion of said mutilated gear 8O engaging gear 76 and the toothed portion of said mutilated gear S1 engaging the idle gear, so thatrotary movement of the shafts will cause alternate movement of the dipping wheel in opposite directions.

13. In a machine of the character described the combination with shaft 11, wheel17 journaled thereon and provided with crown teeth 19, cam 66 on said shaft, plate 22v carried by said shaft and provided with a spring actuated sliding block 2l,said block havingalug 20 adapted to engage the crown teeth and a latch 25, of sliding collar 43 having a cam 42 which when engaged by the latch moves the sliding block backward and disengages the lng from the crown teeth, vertically movable arm 74, vertically adjustable rod 69 by which said arm is carried a block 54 by which said rod is carried, screw shaft 57 and a lever 62 carrying a threaded block 63 which is adapted to engage the screw shaft when the lever is moved inward by cam G6 whereby arm 74 is moved upward and engages sliding collar 43 and moves the cam out of engagement with the latch so that lng 20 will move into engagement with the crown teeth again.

14..The combination with shaft 11,driving mechanism therefor the dipping wheel journaled on said shaft, the carrier, and mechanism whereby the dipping wheel is rotated in opposite directions to raise or lower the carrier, of mechanism for connecting shaft 11 vand the driving mechanism and for discon- ITO necting the driving mechanism when the carv rier is at the lowered .positionand automatic mechanism substantially as described and shown whereby shaft 11 and the driving mechanism are again connected after the carrier has remained at the lowered positionfor a predetermined length of time.

15. In a machine of the character described the combination with the carrier and a dipping wheel from which it is suspended, of mechanism for rotating the dipping wheel in opposite directions with va retarded movement so that both in ascending and descending the movement of the carrier will grow slower from start .to finish. v

16. In a machine of the character described the combination with a vertically movable carrier, shaft 11, wheel 17 journaled on said shaft and suitable means for connecting said shaft and wheel at the beginning of the lowering movement and for disconnecting them at the end of the raisingmovement, of sliding collar 43 carrying a cam 42 by which said shaft and Wheel are disconnected at the end of the lowering movement, vertically movable block 54 and an adjustable arm 74 movingin connection with said block by which collar 43 and the cam may be moved out of operative position and said shaft and wheel again connected after the carrier has remained at the lowered position for a predetermined length of time.

17. In a machine of the character described the lcombination with a vertically movable carrier, shaft 11 carrying a cam 6G, wheel 17" journaled thereon and suitable means for connecting said shaft and wheel at the beginning of the lowering movement and for disconnect ing them at the end of the raising movement, of collar 43 carrying a cam 42 by which said shaft and wheel are disconnected at the end of the lowering movement, screw shaft 57,

vertically movable block 54, lever G2 pivoted to said block and carrying a threaded block adapted to engage the screw shaft, a spring acting to normally hold the threaded block ont of engagement, arm 74 by which collar 43 and the cam may be moved out of opera tive position, a rod 69 which turns within arm 74 but; moves said arm in the vertical plane, said rod being vertically adjustable relatively to block 54 thus determining the time that must elapse after the threaded block has been moved into engagement with the screw shaft by cam GG and shaft 11 and wheel 17 have been disconnected before arm 74 will 'engage collar 43, move the latter out of position and permit wheel 17 and shaft l1 to be again connected to produce the raising movement of the carrier.
