GEARING FOR STENTERING-MACHINES.
Specification of Letters Patent.
Patented Nov. 9, 1909.
Application filed August 31, 1909. Serial No. 515,550. 7
To all whom it may concern:
Be it known that I, ALBERT EDWARD SIMP- sox, a subject of the King of Great Britain and Ireland, of 87 Gigg lane, Bury, in the county of Lancaster, England, have invented new and useful Improvements in Gearing for Stentering-Hachines, of which the fol lowing is a specification.
This invention relates to means in connection with stentering machines, by which the fabric can be straightened as it passes through the machine by giving variations of speed to one of the sprocket wheels by which the clip-carrying chains are driven, after the manner described in the specification of United States Patent No. 714,078, and the object of the present invention is to provide an improved and simplified construction, or arrangement, on this principle in which the portions of the gearing by which the straightening of the fabric is effected have no wearing parts in moving contact relatively to each other, except when the gearing is in use for straightening the fabric.
In the accompanying drawings, Figure 1 is a sectional view of the mechanism embodying my invention; Figs. 2 and 3 are elevation and plan respectively of the brake strap mechanism; Fig. 4 is a vertical section partially broken away, of a modified structure, the pinions J and J being shown in section though lying behind the plane of the main section; and Fig. 5 is a broken sectional plan on the line 55, Fig. 4, to show the idler between pinions J and K.
In the construction shown in Fig. l, the sprocket wheel A is fixed to a toothed wheel B, which is shown as an internally toothed wheel. The said toothed wheel B is mounted loosely on a shaft C, on which is fixed a driving disk D, to which is secured a casing E. The driving disk D carries a pinion F meshing with the said internally toothed wheel B. Formed integral with, or secured to the said pinion F is a worm-wheel G, with which meshes a Worm H, mounted loosely on a spindle I, secured in the casing E, and driven in one direction, or the other, through a bevel toothed wheel J, formed with or secured to the worm H and meshing with two bevel toothed-wheels K and L, the wheel K being mounted loosely upon the shaft C, and the other wheel L being mounted loosely on the extended boss, or sleeve, 70
of the bevel toothed-wheel K. By rotating the worm H in one, or the other direction, while the shaft C is rotating, a variable motion is impaired, through the gearing described, to the sprocket wheel A, so that the motion of the latter is retarded or accelerated, according to the direction in which the worm H is driven. Each of the said two bevel toothed-wheels K and L is provided with a brake, preferably consisting of a brake pulley (/0 and Z respectively), one of which brake pulleys is situated immediately above the other, each brake pulley being provided with a brake strap (/0 and Z respectively) so that, by the operation of these brakes, the sprocket wheel A can be retarded, 0r accelerated more or less. WVhen the sprocket wheel is running at normal speed, the whole of the adjusting gearing described, except the brakes, rotates together. The brake straps are such that when not in use they spring clear of the brake pulleys. To prevent the work H from rotating when the sprocket wheel is running at normal speed, spring stops (as shown at m), with rounded or inclined heads may be provided in one brake-pulley to engage with rounded or iiiclined recesses in the other brake pulley.
' I may use any convenient means for applying the aforesaid brakes, but I prefer to connect each of the brake straps 70 Z at one end to a pin 7), carried in an inclined slot in the bracket P, the other end of each strap being connected by a pin 11, to one arm of a lever N, centered at n to the bracket P, the other end of the said lever being a handle, by moving which in reverse directions either of the said straps can be tightened up and the other slackened, according to which of the said straps is to be applied to its pulley. In place of using an internally toothed wheel B, to which the sprocket wheel A is fixed, an externally toothed wheel may be used for the pinion F to engage with, the operation being practically the same as when an internally toothed wheel is used.
Fig. 4 shows in section a modification according to this invention. The sprocket wheel A is fixed to a crown bevel wheel B mounted loosely on the shaft C, on which is keyed a casing E, having bearings for ashaft carrying a bevel-pinion F, meshing with the crown bevel-wheel B. Integral with or fixed to the said bevel-pinion F is a worm-wheel G, with which meshes a worm H, on a spindle I, mounted in the casing E. Pinions J, J carried by the spindle I, and driven by pinions K, L, mounted loosely on the shaft C, rotate the worm H in one direction or the other. One of the pinions K, L (L being so shown) is geared directly with the corresponding pinion (J on the shaft I, and the other (K) of the said pinions is geared with the other pinion (J) on the said shaft I, through an intermediate pinion :0 (Fig. 5). By rotating the worm H in one direction, or the other, through the pinions described while the shaft C is rotating, a variable motion is imparted to the sprocket wheel A, so that its motion is retarded or accelerated, according to the direction in which the worm H is turned, as in the arrangement, Fig. 1. Each of the pinions K, L, on the shaft C is connected with a brake, which brakes may be arranged after the manner of those used in connection. with the bevel wheels shown in Figs. 1 to 3, and they are so illustrated. I have also shown a stop such as is hereinbefore described to prevent the worm H rotating when the sprocket wheel A is to rotate at normal speed. The aforesaid casing is preferably shaped as shown so. as to extend in each direction to form a protection for the gearing on each side.
I claim as my invention:
1. In mechanism of the character described, a driving shaft, a toothed wheel loosely mounted thereon and a sprocket wheel fixed to said toothed wheel, in combination with a driver secured to said shaft, a pinion carried by said driver and gearing with said toothed wheel, a worm wheel carried by said pinion, a worm gearing therewheel fixed to said toothed wheel, in combination with a driver secured to said shaft, a pinion carried thereby and gearing with said toothed wheel, a worm wheel carried by said pinion, a worm gearing therewith carried by said driver, and gearing for driving said worm in either direction together.
with brakes controlling the action of said gearing, whereby the speed of the sprocket wheel is accelerated orretarded, substantially as described.
3. In variable speed gearing, a driving shaft, a toothed wheel mounted loosely thereon and a driven member fixed to the latter, in combination with a driver secured to said shaft, a pinion carried by said driver and gearing with said toothed wheel, a worm wheel carried by said pinion, a worm gearing therewith carried by said driver and means for causing said worm to be driven in either direction whereby the speed of the driven member is accelerated or retarded, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ALBERT EDWARD SIMPSON.
