DEVICE FOR REGULATING SPEED.

SPEGIFICATIONforming part of Letters Patent No. 687,257, dated November 26, 1901.

I Application filed March 18, 1901. Serial No. 51,684. (No modeln To to whm'n it may concern.-

Be it known that we, CHARLES OOoNNoR, a resident of New York, (Greenpoint, borough of Brooklyn,) in the county of Kings, and GEORGE O. AHRENS, a resident of New York, (Blissville, borough of Queens,) in the county of Queens and State of New York, citizens of the United. States, have invented a new and Improved Device for Regulating Speed, of whichthe following is a full, clear, and exact description.

Our invention relates to devices for regulating the speed of machinery, being especially adaptable to power-pump machinery.

The purpose of the invention is to provide a simple mechanism for changing or regulating the speed of power machinery without changing the diameter of the driving-pulley or interfering with said pulley or the driving- I belt in any manner.

A further purpose of the invention is to provide a device for regulating speed capable of ready adaptation to all manner of pumps.

The invention consists in the novel construction and combination of. the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar characters of reference indi-- cate corresponding parts in all'the figures.

Figure 1 is a front elevation of the device shown applied to the frame of a vertical form of power pump. Fig. 2 is a side elevation of the device applied to a verticaltype of powerpump, and Fig. 3 is a plan viewof the device applied to the same formlof power-pump. Fig. 4 is a side elevation of the device applied to the frame of a horizontal type of powerpump, and. Fig. 5 is a plan view of the device applied to a rotary form of power-pump.

A represents a portion of the frame of an upright power-pump, B represents the pumpshaft, and C a large gear-wheel which is secured to one end portion of the said pump shaft. Preferably at the front of each side of the said frame A, at ornear the top, arms 10 and 11 are carried outward, one arm upward and the other more or less downward, as. shown in Fig. 2, and each pair of arms 10 and- 11 serves to-support a hollow segmental cas-T ing D, the are upon which the casing is constructed being taken from the center of the pump-shaft B. I In each casing D a journalbox 12 is mounted to travel,'and these boxes extend beyond the outer faces of the casing D and have their forward or con'vexed edges at their extended portions provided with series of teeth 13, as is best shown in Fig. 2. These boxes 12 serve to journal a driven 6o shaft 14, which when the device is applied to the vertical form of pump is located in front of the pump-shaft B. The driven shaft 14 is provided within the frame with an attached gear 15, as is best shown in Fig. 1, and at one outer end of the said driven shaft l l'apinion 26 is secured,which pinion meshes with the teeth of the large gear 0 on the pumpshaft B, as is also best shown in Fig. 1.

The driven shaft 14 is raised and. lowered on the arc of a circle usually by means of the following mechanism: A shaft 16 is journaled in suitable bearings 28, attached to the cas-' ings D, and this shaft 16 is provided with a handle 27 at one end and with beveled gears 17 near its ends. These bevel-gears 17 mesh with bevel-gears 18, and the bevel-gears 18 are'carried .by suitable shafts 19, journaled in suitable bearings attached to the front of the casings D. Each shaft 19 is provided with a worm-thread 21, which wormthreads mesh with the teeth 13 on the journal-boxes 12. Thus by turning the shaft 16 thejournal-boxes 12 are raised and lowered, yet the pinion 26 always remains in mesh with the large gear O on the pump-shaft. .Eaoh vertical shaft 19 is preferably provided with a collar 22 above its worm-thread, as shown in Fig. 2; but we desire it to be understood that the construction just described may be varied in many particulars.

The main drive-shaft E is journaled in suitable bearings attached to the front of the frame A, and this drive-shaft E is provided at one of its ends with fast and loose pulleys 5 23','as shown in Figs. 1, 2, and A cone of gears F is mounted to slideon the drive-shaft E within the casing A, yet turn with the said shaft, and this cone of gears F is shifted on the drive-shaft through the medium of asuit- Ico able lever 24. (Illustrated in Fig. 3.1) The gear..15 on the driven shaft is adapted to meshwith any one'of the series of gears c011- stituting the cone of gears F. Thus it will be observed that when the driven shaft 14: is

raised through the medium of the adjusting mechanism described the cone of gears F can be shifted on the drive-shaft, so as to bring any one of the gears constituting such cone in alinement with the gear 15 on the driven shaft, and that when the driven shaft 14 is adjusted downward its gear 15 will mesh with the desired gear on the drive-shaft, and the speed communicated from the drive-shaft to the pn m p-shaf 11 will be increased or decreased without removing the driving-belt from the driving-pulley andthat the driving-pulley will at all times be of the same diameter, thus utilizing therfull power of the driving-belt.

In Fig. 4 we have illustrated the application of the device to a horizontal form of pump in which the frame is designated as A. In this construction of pump the drive-shaft E is journaled in suitable bearings above the pump-shaft B, which latter shaft is provided with a large gear 0 at one end, meshing with a pinion 26 on the end of a driven shaft 14, which driven shaft in this instance is below the drive-shaft E. This driven shaft 14 is mounted in boxes 12, provided with teeth 13, and the boxes are held to slide in segmental casings D. The same adjusting mechanism for the driven shaft 14: is shown applied to the horizontal form of the pump, comprising a shaft having a handle 27 attached at one end, the said shaft being provided with bevel-gears 17 near its ends,which mesh with bevel-gears 18, which are secured to worm-shafts 19, the worms 21 of which shafts mesh with the teeth of the boxes 12. The driven shaft 1& is likewise provided between its ends with a large gear 15, and as the driven shaft 14: is adjusted this large gear 15 is adapted to mesh with any one of a series of gears forming a conical set of gears F, mounted upon and to turn with the driveshaft E, the said drive-shaft E being provided with fast and loose driving-pulleys 23. In regulating the speed the driven shaft 14 is adjusted to or from the drive-shaft E, as has been stated, so as to bring the gear 15 into mesh with any one of the gears in the conical set of gears F.

In Fig. 5 we have illustrated the adaptation of the device to a rotary form of pump in which the pump-shaft is designated as B and the frame as A The pump-shaft B is provided with a large gear which meshes with a pinion 26", carried by a driven shaft ltfljournaled in toothed bearing-boxes mounted to slide in segmental casings D attached to the pump-frame. These boxes are moved up and down in the segmental casings by a shaft 16*, suitably mounted on the frame, provided with a handle 27 at one end and with bevel-gears 17 at or near its ends,which bevel-gears 17 mesh with corresponding gears 18, located on worm-shafts 19, the worms 21 of which engage with the teeth of the boxes provided forthe driven shaft 14 The driven shaft 14 is movable to or from a driveshaft E on which a series of gears F arranged in conical form, are mounted to turn and slide, suitable shifting mechanism being employed, so that any one of the gears F in the conical set may be brought into mesh with the gear 15 secured on the driven shaft at a point between its ends.

The device is exceedingly simple. It is adaptable to any form of pump and to other machinery, and through its medium the speed may be changed or regulated without touching the driving-belt or changing the diameter of the driving-pulley employed.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. In devices for regulating the speed of machinery, a drive-shaft, a cone of gears mounted to slide upon and turn with the drive-shaft, a driven shaft, a worm-gear for adjusting one shaft to and from the other, and a gear carried by the driven shaft and adapted to mesh with any gear in the cone of gears, as set forth.
