Ari-00A" Patented Feb. 21, 1933 UNITED STATES PATENT OFFICE WILLIAM HALE, OF FORT W'ASHINGTON, PENNSYLVANIA, ASSIG-NOR TO B. H. BEAUMONT COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA WINDING MACHINE Application filed February 17, 1931. Serial No. 516,343.

The invention relates to winding machines having drums well adapted to be connected by cables to a drag scraper in order to cause it to move toward and away from the winding machine as is well understood by those skilled in the art.

One object of the present invention is to utilizechange of directionof rotation of a reversible motor, or like driving part, toautomatically control the movements of the winding drums, either to make one of them run faster than the other in the same direction or to free one of the drums and drive the other, or both.

Another object of the invention is to provide for interchangeably operating either one or the other of the drums in the manner indicated. Another object of the invention is to provide, in cases where desired, for automatically causing whichever drum is being driven to brake or check the free drum.

Other objects of the invention will appear from the following description at the end of which the invention will be claimed.

Generally stated, the invention comprises a winding machine having a pair of drums, a reversible motor, and means automatically responding to the reversal of direction of rotation of the motor and constructed for controlling the movements of the drums, with or without automatic braking devices operated by the driven drum to check the free drum.

The invention also comprises the improvements to be presently described and finally claimed.

In the following description reference will be made to the accompanying drawings forming part hereof and in which Figure 1 is a top or plan view of a winding machine embodying all of the features of the invention although certain parts are concealed or hidden by reason of their location.

Fig. 12 is a detail view of one of the parts shown in Fig. 11.

In the drawings 1 is the driving shaft, and 2 and 3 are drums driven by the driving shaft as will be presently described. Either one of the drums may be driven in the same direction of rotation and at a fast'and slow speed, and this is accomplished by means that will be designated speed selector means. When either one of the drums is driven the other is free from the driving shaft 1 and it is checked or braked. This may be accomplished by mechanism that is well understood and now in use but I have provided automatic braking or speed checking mechanism which will be described. There are means for driving eitherone of the drums faster than the other and they willbe designated drum selector means. 4 is a reversible motor shaft adapted to rotate in either'direction. 5 is a high speed gearing and 6 is low speed gearing connected with the motor shaft 4. There is a clutch between the driving shaft and the high and low speed gearing, and this clutch is responsive to change in direction of rotation of the motor shaft and is adapted, upon change ofdirection of rotation of the motor shaft, to automatically connect. the driving shalt 1 with "one speed gearing and to disconnect the driving shaft from the other speed gearing. Several forms of such clutch mechanism are shown and the form illustrated in Figs. 1 and 2 will be first described; Fast on the driving shaft 1 is a bar 7 The toothed wheels 8 and 9 of the slow and fast'gearing rotate freely in respect to the shaft 1, and they are provided with barrels 10 and 11, arranged to rotate with them. Around the barrels are friction bands 12 and 13. The ends of these bands are connected with arms 14 and mounted in the opposite ends of the bar 7. These bands and barrels constitute clutch elements and when the gear wheels 8 and 9 are rotated in one direction, one of the bands connects the bar with one of the sets of gearing so that the shaft 1 is driven at one speed, and when the gear wheels 8 and 9 are rotated in the other direction, the other of the bands connects the bar with the other of the sets of gearing so that the shaft 1 is driven at a different speed. The band which is not tightened in the fore oing operation is slack and therefore entire y free from the barrel which it surrounds.

For this purpose the points at which the ends of the bands 12 and 13 are hinged to the turnable arms 14 and 15 do not lie in the center line of the bar, and the rod 16, Fig. 2, connected at its ends with arms 17 and 18, integral with the arms 14 and 15, limits the turning movement of the arms 14 and 15 and determines which band shall be the driver when the motor shaft 4 turns in one direction, and which band shall be the driver when the motor shaft turns in the other direction. The driving action can be interchanged between the hands by connecting the rod 16 with arm 18 at 19. The rod 21 and the arms to which it is connected, when present, serve to balance the rotating structure.

As shown in Figs. 1 and 2, the drum selecting mechanism is a duplicate of the speed selecting mechanism just described, and consequentl is numbered with the same numbers prime Fast to the driving gear 22 of drum 2 are a brake barrel 23, and one of the barrels of the clutch mechanism, and these are free for rotation on the shaft 1. The drum 3 is similarly provided with a brake barrel 24 and with the parts correspondingl to the parts referred to in connection wit drum 2. From the foregoing descri tion it will be evident that when the shaft 1 is driven in one direction, one of the drums is driven and the other drum is free, and that when the shaft is driven in the other direction the formerly free drum is driven and the formerly driven drum is free, and that selection may be made between the drums in res ect to reversal of direction of rotation of't e shaft 1. The relative positions of the hinges of the bands and the position in which the rod 16 is connected are the factors which effect the above result.

The rotation of the drum which is free from the driven drum and disconnected from the driving shaft 1 is caused by the cable pull and should be checked, There are well known brakes for this purpose and they may be employed in connection with the described s ed and drum selector mechanisms, or either of them, but a description will be given of the braking mechanism forming part of the present disclosure.

Referring to Figs. 6 and 7, around the brake barrels 23 and 24 are friction bands 25, and the ends of these bands are pivotally connected to arms 26 and 27 on a turnable shaft 28. The arms 26 and 27 are set out of alignment, so that as one band is tightened on its barrel by rotation of the barrel, it turns the rod 28 thereby releasing the other band leaving the drum which it controls free to be driven in the manner described.

Referring to Figs. 3 and 4, a description will be iven of a modified form of means for per ormin the function performed by the rod 16 an its accessories shown in F' 2. On the pivot shafts 29 and 30, to Wllllfil the arms 14 and 15 are fast, are mounted segments of wheels 30' and 31, and a chain 32 passes around these segments of wheels. The angular relation of the arms 14 and 15 is changed by turning one of these segments, for example, the segment 31. For this purpose the pin 33 is withdrawn and the segment 31 turned and the pin 33 replaced in an appropriate notch 34. The spring 35 facilitates this operation. Anchor screws 36 are provided and they fasten the chain to the wheel segments.

In the modification shown in Fi 8, use is made of two face clutches of w ich the driving members 37 are attached to the high and low speed gear wheels 9 and 8 and are arranged between collars 38 and 39 of which the latter is provided with a spring 40. The driving members 41 and 42 of these clutches are provided with links 43 pivoted to the hub 44 fast on the shaft 1, and the links are provided with inter-engaging segmental toothed wheels. The hub 44 1s provided with stops 45 and 46. When the wheels 8 and 9 are turned in one direction by the motor shaft 4, for example, in the direction indicated by the arrow, the link 43 of the member 42 is turned against its stop 46, so that the shaft 1 is driven at hi h speed. Upon reversal of the direction 0 rotation of the motor shaft 4 the same action occurs with respect to the link 43 of the clutch member 41, and the shaft 1 is driven at slow speed and the link 43 of the clutch element 42 has released the element 42, forcing element 41 into light contact with element 37 so that the shaft 1 is driven at low speed. In each case the shaft 1 is driven through the hub 44, and one or the other of the stops 45 and 46, acting on the corresponding link. To reverse the action, the stops 45 and 46 are transferred to the holes indicated in dotted lines on the hub 44.

In the modification shown in Fig. 9, the hub 47 on the shaft 1 is provided with one or more endwise slidable bolts 48 having beveled ends and adapted to cooperate with studs 49 and 50 on the fast and slow gears 9 and 8, loose on the shaft 1. When the gears 8 and 9 turn in the direction indicated by the arrow, the bolt 48 is pushed by stud 5O endwise into position for engaging stud 49. Upon motion of the gears in the other direction the reverse action takes place. To reverse the action of the device the bolt is removed and turned over and replaced. In the structure shown in Fig. 10, the drum 51 is fast on the shaft 1 and it is provided with cam faces 52 and hooks 53 which operate the latter to drive the shaft 1, and the former to shift the clutch member 54- into engagement with either of the members 37 connected with the gears 8 and 9, so that when the direction of rotation of the high speed gear attached to the clutch element 37 is in the direction of the arrow, hook 53 on one of the cams 52 pushes a roll 55 attached to the element 54 into contact with the part 37 and then drives the same through the part 53. Upon reversal of the direction of motion of the gears 8 and 9, the described action occurs in respect to the clutch element 54 and the element 37 connected to gear wheel 8.

To reverse the action, the drum 51 is made in two parts of which the lefthand part in the drawings is fast to the shaft 1, and the righthand part is connected to the lefthand part by a bolt 56, which, for the purpose referred to is put into the hole 57.

In the modification shown in Figs. 11 and 12, the construction and operation are the same as described with respect to Fig. 9, and it will be understood that there are two bolts of which the ends 62 are indicated in Fig. 12. Each bolt is arranged diagonally in a slot in the hub 61 and at each end it is provided with a head 62 rectangular in outline. The action can be reversed by taking out said bolts and putting them in the oppositely positioned slots 55. Reversal in the direction of movement of the gear wheels 8 and 9 (as that shown by the arrow) causes the projection 68 to act on the other side of the head 62 and shift the bolt into position for engaging the projection 64 on the gear wheel 9 which now drives the hub and shaft 1.

The clutch mechanism shown in Figs. 3 and 4t, and 8 to 12, inclusive, can be employed for clutch selection by substituting the gear wheels 22, Fig. 1, for the gear wheels 8 and 9 in the other figures.

70, Fig. 6, indicates a supporting hook, movable on a fixed stud and it serves to support the band 25 in its various positions with sufficient flexibility to permit of the described operation of the band.

Referring to Figs. 6 and 7, the pin 201 and the pair of holes for its reception are alterable means whereby the brake may be held in off position to prevent application in either one of two directions. Similarly pin 45 in Fig. 8 and bolt 56 and hole 57 in Fig. 10 are alike alterable means, assuming that the structures of Figs. 8 and 10 are used as brakes.

It will be obvious to'those skilled in the art to which the invention relates that modifications may be made in details of construction and arrangement and matters of mere form without departing from the spirit of the invention which is not limited to such matters or otherwise than the prior art and the appended claims may require.
