Application filed February 2, 1909. Serial No. 178,158.

To all whom. it may concern:

Be it known that I, Josnru J. Watson, a citizen of the United States, residing at Uhicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Variable-S ed DliV' iug Mechanism, of which the fol owing IS a specification, reference being had to the accom anying drawings.

y invention relates to dri-v'm mechanism which, driven by a driving-s iaftfotab ing at a determined speed, may be given a high and low speed for the purpose of during machines in which such lurahty of speed is desirable, particular y printing presses, and the object of my invention to provide a new and improved driving mechanism of the character described, in which the slow speed mechanism will not be disconnected until the high speed mechanism is being brought into engagement, thus avoiding the coming of an interval of time between the throwin oil of the low and the throwing in of the high speed, during which the press, or similar driven machine, running by its own momentum alone would be apt to slow down, and in the case of a printing press particularly cause the breakage of the webs.

In the accompanying drawings,-Figure 1 is a top or plan view partly in horizontal section; Fig. 2 is an end view, showing a portion of the side frame and some of the driving gears of .a printingl press in dotted lines; "ig. 3 is a section on inc 33 of Fig. 1; Fig. 4 is a section on line 4-4 of Fig. 3- Fig. 5 is a. section on line 5-5 of Fig. 4; an Fig. 6 is a detail of the ratchet and drum driving connections, being a section on line 6-6 of Fig. 1.

Referring to the drawings,! indicates a frame, and 8 and 9 the side frame-bars upon which rest a. side-frame 10 of the press indicated by dotted lines in Fig. 2.

11 indicates the main driving-shaft, which is journaled in suitable lmirings, as 12, in the frame 7.

13 indicates a driving-pinion, which is adapted to be connected to a suitable soumc of power, preferably 1:. hi h-spccd motor driven at a nstant dcsircc s eed.

[4 indicates a clutch-mom ier, which is feathered on the shaft ll and is ada ted to ho Hllll longitudinally thereof. On t io hub of the clutch-member 14. is a peripheral groove 15 which is ada ted to be e db the forked end 16 o a shiftin le gr 1% pivoted to the framework. The ot er end of the shifting-lever IT is rovided with a fork 18 which straddles a ift-bar 19 slidiugly mounted in suitable bearings 20 on the frame.

2l22 indicate collars, which are pinned to the slide-bar 19 a suitable distance apart. 23 indicates a collar, which is loosel mounted on the slide-bar 19, with a spira spring 2-1 interposed between it and the col- \Vhen the shifting-lever 17 is shifted in one direction or the other by the el ment of the collars 23-24 on the di i- 19 in the manner hereinafter described the clutchmember 14 will he slid in one direction or the other longitudinally of the shaft 11.

25 indicates a clutch-member, which is ournaied on the shaft 11 and is provided with a hub 26. The clutch-member 25 is rovided with a flange 27 whose inner surace is beveled to engage the corr ondmgly beveled outer perip cry of the utchnembor 14 so that when the two are forced into engagement b the movement of the clutch-member 14 e clutch-member 25 will be rotated with the shaft 11.

28 indicates a collar pinned on the shaft 11 and abuttin upon the interior surface of the clutch-mom er 25 and holding it in position in one direction.

29 indicates a car, which is secured upon the hub 26 of 't 1e clutch-member 25. B means of intermediate gear 30 meshing wit said gear 29, intermediate gear 31 meshing with the gear 30 motion is communicated to the drivii gears 323334 of the press shown in ii otted lines in Fig. 2.

It will be obvious that when the clutchmembers 14 and 25 are forced into engagement by the sliding of the clutchinembcr 14 on the shaft 11, the clutch-member 25 will be rotated at the some speed as the shaft 11 and in the same direction and the press will be driven at full speed.

35 indicates a drum, which is secured on the hub 26 of the clutch-member 25 and is provided with a plurality of pawls 36 on its outer surface-4 mt is, the surface away from the gear 29.

37 indicates a gear, which is rotatably mounted upon the shaft 11, its inner end abuttin upon the outer surface of the clutch um 85.

38 indicates a ratchet-disk, which is fixed upon the hub of the gear 37 against the outer surface of the drum 35 and is adapted to enga e the pawls 36 of the drum 35.

89 in 'cates a collar, which is pinned upon the shaft 11 against the outer face of the gear 37, thus cooperating with the collar 28 to hold the parts in position on the shaft against longitudinal movement thereof, but permitting the free rotation of the parts upon the shaft.

40 indicates a pinion secured to the shaft 11 inside the bearing 12.

41 indicates a large gear, which is rotatably mounted upon a shaft 42 and meshes with the pinion 40. The shaft 42 is fixed in suitable bearings, as 43, on the frame 7.

44 indicates a gear which is secured upon the inner end of the hub of the gear 41 and rotates therewith.

45 indicates a spider provided with a hub 46 which is rotatably mounted upon t e shaft 42 and is provided with a luralitjv of arms 47, shown three in number. pon each of the arms 47 is mounted a pinion 13, which pinions mesh with the gear 44.

49 indicates a r, which is secured upon the hub 46 of e spider 45.

50 indicates a drum, which is revolubly mounted u on the hub 46 of the spider 45 and the ha of the gear 49 so as to rotate freely thereon. The inner surface of the drum 50 is provided with a peripheral gear 51, which meshes with the gears 48 on the spider 45. The outer of the drum is provided with a brake 52 operated by a flexible brake-band 53 in the manner hereinafter provided so as to hold the drum 50 ti ht a net rotation.

e gear 49 on the hub of the s ider 45 meshes with the gear 37 on the sh 11.

From the above description, it will be ob vious that if the drum 50 is not held against rotation, but if the drum 50 is freed from the brake 52 and allowed to rotate freely, the rotation of the large gear 41 driven by the pinion 40 will by means of the gear 44. retats the gears 48 on the ider 45 and the drum 50 will be rotated wit out rotating the spider. If on the other hand, the drum is braked and held against rotation, the enmcnt of the gpar 44 on the hub of the rge gear 41 wit the gears 48 will cause them to travel around the drum by reason of their e gement with the internal gear 51 on said rum and will rotate the spider 45. The driving-shaft 11 being rotated in a oloclrwise direction, the large gear 41 mil be carried in the opposite direction, and the drum 50 being cld fast the spider will travel around in the some direction as the gear 41-that is to any, in a. contra-clockwise "action-and at a much slower speed by reason of the difference in size of the pinion 40, large gear 41, and the difierent sizes of the gear 4-! and the gear 51. By reason of the engagement of the gear 49, which is fast to the hub of the s ider, the gear 37 on the driving-shaft 11 w: i be driven in the same direction as the shaft, but at a much slower speed, depending, of course, upon the relative diameters of the gearing above described. This will rotate the ratchet-disk 38 in the same direction and at the same speed, and the ratchet-disk 38 engagin the pawls 86 on the disk 35 will drive it am the gear 29, which is fixed to the hub of the clutch member 25, in the same direction and at the same speed, thus through the medium of the gears 80 and 31 driving the driviu gears 32-33-34 of the press at slow spetxf.

I have illustrated in the drawin suitable mechanism for throwing the clutc unembers into and out of en gement and for applying the brake to e drum 50.

54 indicates a rock-shaft, which is journaled in suitable hearings on the framebars 8 and 9.

55 indicates a hand-lever, which is journaled u n the end of the rock-shaft 54.

59 indicates a pin, which is rotatably mounted in the lever 55 and carries u on one end and fixed thereto a dog 60 whic is adapted to enga with the ratchet-teeth 57 and upon the ot er end and secured thereto an arm 61 which, as the lever swings from right to left in F 3 and 5, is adapted to be engaged by a pin 62 on the outside of the frame-bar 9-50 as to force the arm 61 down and lift the dog 60 from the ratchet-teeth 57, as hereinafter described.

63 indicates a spring-seated awl on the lower arm of the lever 55, whi is ada ted to cage the ratchet-teeth 58 on the dis 56 when t e lever is swun in the opposite direction-that is from le 1'. to right in Figs. 2, 3 and 5.

64 indicates a cam on the lower arm of the lever 55, which is adapted as the lever is moved into the position shown in Fi 2 and 3 to engage a swin 'ntg arm 65 w iich hangs pivotal y suspen e from suitable bearings, as 66, on the under side of the sidebar 9 and is provided with a latch 67.

68 indicates a collar secured on the rockshaft 54 and provided with an arm 69, preferably in l therewith, which, when the rock-ehaftns rocked into slow-speed position, hereinafter described, is lifted so that when the ewingin arm 65 is freed from the cam 64 the latch 7 will fall below the arm 60 and hold it so as to prevent the shaft 54 ill) from rocking backward lmtil said arm and latch are freed by the swinging of the arm from the cam 64.

indicates a collar secured to the rockshaft 54 and provided with an upward-extending arm 71.

72 indicates a. rod, one end of which is pivotally connected with the up r end of the arm 71 and the other and s ides freely in a lug 78 on the frame-bar 9, the in being -suitably perforated to receive the r 72.

74 indicates a collar, which is pinned, or otherwise adjustably secured, on the rod 72, and between which and the in 73 is interposed a spiral-sprin 75 whic is compressed when the rock-s aft is rocked so as to move the arm 71 to the left in Fig. 3 and tends to restore the same to normal position when free to act.

The hand-lever 55 is provided with the usual spring-seated dog 76 which is ada ted to engage notches in a rack-bar 77. T ese notches are three in number, marked H, S and 0, to indicate, ectively, the highspeed, slow-speed and 0 position.

78 indicates a link, one end of which is pivotally connected with the lower end of the lever 55 and at the other end with a lever 79 which is 'ournaled upon a. horizontal axle 80 in suite le han re 81 depending from the frame-bar 9. he upper end of the lever 79 is provided with a segmental beveled rack 82 which meshes with a beveled gear 83 secured to a shaft 84 which is vertically journaled in the hanger 81.

85 indicates a collar secured to the lower end of the shaft 84 and provided with a horizontally-extending arm 86.

87 indicates a link, which is pivotally connected at one end with the arm 86 and at the other end with the end of the shifthar 19.

It will be evident that as the lever 55 is rocked in one direction or the other the shaft 84 will be rocked in one direction or the other by the action of the beveled racksegment 82 on the beveled gear 83, and swinging the arm 86 correspondingly this, by the connection of the link 87 will slide the slide-bar 19 in one direction or the other in its bearings. When the lever 55 is swan" to the left in Figs. 2 and 3, this motion wi I move the slide-bur toward the frame-bar 9, and when the sprin -seated collar 23 onages the fork 18 an shifting-lever 17 the suiting-lever will be rocked to slide the clutch-member 14 into engagement with lhc clutch-member 25. When the lever is moved in the opposite direction, the slidebar 19 is moved in the opposite direction and the clutclmncmber is disengaged.

88 indicates a collar secured to the shaft M and provided with an arm 89 on which is mounted a pawl 90.

91 indicates a collar, which is hmocly mounted upon the rock-shaft 54 and is pro vided upon its surface with a lug 92 ada acd to be engaged bv the pawl 90. Tim collai 1 is also provid. with an arm 93, preferably formed integral therewith.

94 indicates a link. which is pivotally conucclcd at its upper cud with the end of the arm 93 and at its lower end to the outer end of a brake-lever 95 which is journaled in a suitable bearing 96 on the frame and car- I'ics at its other end a brake 97 which is adapted to engage the outer periphery of the clutch-member 25 and when brought to hear a dust it to brake the said clutch-memhcr uni, stop its rotation.

98 indicates a collar on thc cm] of thc rock-shaft 54 and keyed, or otherwise secured, thereto.

99 indicates an arm on the collar J8, preferably integral therewith. and depending downward therefrom.

100 indicates a rock-shaft journalcd in suitable bearings, as 101, in the frame 7 and provided at one end with an arm 102 extending u ward therefrom.

103 inucates a link, which is pivotally connected at one end to the arm 99 and at the other end to the arm 102 on the rockshaft 100.

104 indicates a collar, which is keyed, or otherwise secured, to the rock-shaft 100 opposite the brake 52 and provided with in 105-106 to which the ends of the flexilfiz brake-band 53 are adjustabl secured. \Vhen the collar 104 is rocked c ockwisc, as hereinafter described, it is obvious that the brake-hand will be tightened and the brake applied to the drum \Vhen the rocksmft 100 is rocked in the opposite direction the brake will be freed.

The operation of the above-described device is as follows: The drawings indicate the arts in the full-speed )ositlon with the land-lever 5.) moved to t- 1e extreme left in Fig. 2 and the latch 76 in thc high-s d notch. In this position the clutch- mom crs 14 and 25 are forced into engagement with each other and the presn is driven at full mood in the manner above descrilml. In his position also the cam 64 is in engagement with the swinging arm 65, swinging it out from its normal position, and the arm 61 has been en :1 ed by the pin (i2 to lift the latch 60 out o t w ratchet-teeth .17 and the rock-shaft 54 is yicldingly held in normal position by the sprin 75, the brakes 52 and 97 both llllllg oil. I the lover is now swung to the l'l ht to the oil position this movement wil first of all opcratethe shiftinghar 1!) to move the clutch- members 14 and 21" out of on agcmcnt. Before the lever reaches the o position lhc pawl 63 on igcs one of the ratchet-teeth 58 on tho din m: and the l'mek-uhul't M in rockcd in a clock- Wit! dirw'tion. This, of counw. rocks the collar 88, on which the arm 89 and its pawl 90 are so disposed that just before the oil )osition is reached the pawl 90 engages the lug 92 on the collar 91, rocks the same in the same direction with the rock-shaft and rocking the arm 93 downward rocks the brake 97 upward and brings it into engagzinent with the flange 27 on the clutch-mem r 25 causing the stoppa of the mechanism and the press, or ot ier driven machine, is brought to rest. It now being desired to start the mechanism up, the lever is swung toward the slow-speed position. As soon as the swinging of t e lever begins the link 78 is, of course, moved to the right in Fig. 3, rocking the lever 79, rotating the gear 83 and movin the shift-bar 19 toward the side-bar 9 an bringing the collar 23 into ition to bear upon the shiftin -lever 17. he collars 21-23 are so sp n on the shift-bar that the lever 17 is not r ed until after the hand-lever 55 reaches the slow-speed position, but the collar 23 by the movement to slow-speed position is brought into position to be read to swing the slufting-lever 1'7 as soon as t e lever 55 passes the slow-s position. As the lever 55 is rock from oil to slowspeed position, the dog 60, which is at that time riding upon the pen hery of the disk 56, enga one of the rate net-teeth 57, rocking the disk 56 and the rock-shaft 54 in a contra-clockwise direction, comp the springl75. This rocking of the rock-s ft frees t e pawl 90 from on gemcnt with the In 92, rmit-ting the co ar 91 to rotate an the rake 97 will fall away from the flange 27 on the clutchmember 25 by its own weight. The arts are so positioned that this movement 0 the rock-shaft throu h the operation of the collar 98, am 9 link 10%, and arm 102, rocks the rock-shalt 100 in a clockwise direction and tightens the brake 52 upon the drum 50 holding it a ainst rotation and causing the press to be riven at slow speed in the manner above described. This rocking of the rock-shaft 54 by the movement of the lever 55 into slow-speed position has, by the time it reaches slow-speed position, raised the arm 69 on the collar 68 to such a position as to permit the latch 67 on the swinging arm 65, which is still free from the cam 64, to drop below the said arm 69 and thus hold the rock-shaft a inst backward rotation by the action 0 the spring 75 until said latch is released.

It being desired to move the parts into full-speed osition, the lever 55 is swung toward the ttll-B d notch, and this further movement of the ever causes the gradual engagement of the clutch-members l4 and 25 which begin to come into enga mont as soon as the lever is moved bcyon the slowspecd notch, the beveled surfaces permitting tic movement of the clutch-member 14* which is the same as that of the shaft 11- to be taken up, not suddenly, but relatively rudually by the clutch -mcmber 25. As t iese clutch-members begin to come into engzigement so as to im art to the clutch'memr 25 a higher s ,the movement of the lever causes the arm 61 to be brought into eniagclnent with the pin 62 and the do to e freed from the ratchet-teeth 57. e cam 64 as these clutch-members begin to move into high-s engagement engages the lower end of t to swinging lever 65, forcing the latch 67 out from engagement with the arm 69 and permitting the spring to act. The spring 75, bein free to act, causes the swinging of the arm 1 in a clockwise direction, rotating the collar 70 and the rockshaft 54 in the same direction and throwing oil the brake 52 from the drum 50, allowing the same to rotate freely. The pressis now driven at full speed. As has been said, the clutch- members 14 and 25 are thrown into engagement with one another so that the clutch-member 25 begins to take up the increased speed before the brake on the drum 50 is thrown 0d and therefore while the slow-speed mechanism is still running. (1R cousrje this will drive the 23]} and the rum atagreatcrspecd, utt s will not be communicated to the rest 0% slow-speed mechanism because the ends will sli over the teeth of the ratchet 8 at which I claim as m invention, and desire to secure by Letters atent, is,
