REVERSING MECHANISM FOR IRONING- MACHINES.

Application filed April 14, 1921. Serial No. 461,280.

To all whom it may concern:

Be it known that I, CHARLES N. SING, a citizen of China, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Reversing Mechanism for Ironing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification. I

This invention relates to improvements in ironing machines; and the invention has reference, more particularly, to a novel reversible driving means for association with that type of ironing machine which possesses a rotary ironing roll and slidable work carrying board, together with a means cooperating with the latter and with said ironing roll to cause said board to travel beneath and in contact with said ironing roll.

The invention has for its principal object to provide, in combination with power means for driving the ironing roll and associated board-operating means, reversible transmission means for causing, at the will of the operator, alternate rotation of said mechanism in opposite directions, whereby the work carrying board iscaused to move forward and back beneath the ironing roll.

The invention has for a further object to provide a novel, simple and easily controlled reversible transmission mechanism for ironing machines of the type specified, which may be either incorporated or built directly into the structure of the machine originally, or which may befurnished and mounted as an attachment adapted to be easily and quickly coupled with either old or new iron ing machines of the type mentioned.

Other objects of the invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of the same.

. WVith the various objectsof the invention in view, the samev consists in the novel reversible transmission mechanism for ironing machines hereinafter described; and the same consists, furthermore, in the novel arrangements and combinations of the various devices and parts thereof, as well as 1n the details ofthe construction of the sam al of which will be fully described in the following specification, and then vfinally embodied in the appended claims.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a side elevation of an ironing machine equipped with the novel reversible transmission mechanism made according to and embodying the principles of this invention; and Figure 2 is a horizontal section, taken on line 22 in said Figure 1-v Similar characters of reference are employed in the said views, to indicate corresponding parts.

Referring now to said drawings, the reference character l indicates a frame-work upon which is mounted themechanism comprising the ironing machine. Said framework 1 is providedvwith a pair of transversely opposite bearings 2 in which is journaled the shaft 3 of a rotary ironing roll 4L.

Supported in connection with said framework are a pair of laterally spaced longitudinal guide rails 5, disposed; to extend beneath said ironing roll 4, Associated with said guiderails 5, so asto. extend trans,- versely between the same at desired longitudinal intervals, are a plurality of rollers v6. Carried upon said rollers 6, and guided by said guide rails 5, is a longitudinally movable table or carriage 7 upon which issu p: ported an'ironing board 8 adapted to be carried, by reciprocable movements of said carriage, back and forth, beneath and in contact'with saidironing roll 4. Adjustably mounted in connection with said framework 1 is a bearing frame?) in which is journaledthe transverse shaft 10 ofan impulsion roller 11, which is mountedbeneath said carriage 7 so as to be alined with and opposed in position tosaid ironing roll 4:,

Fixed on one end ofsaid ironing roll shaft 3 is a gear-wheel 12 whichmeshes with and drives agear-wheel 13 fixed on said impulsion roller shaft 10, whereby rotary motion imparted to said ironing roll is transmitted to said impulsion roller 11 in an opposite direction. H 1 v k The reference, character 14 indicates suitably constructed standards or supports,

upon which is secured a bearing frame 15 provided with suitably positioned and alined longitudinal bearings 16, and a transverse bearing 17. J ournaled in said transverse bearing 17 is a transverse "shaft 1 8L, upon the outer nd are s as a are an? #2:

' tor.

Said shaft 18 is axially alined with said ironing roll shaft 3 so that its inner end abuts against the outer end of the latter. Said adjoining ends of said shaft 18 and ironing roll shaft 3 are coupled together, so as to rotate together, by means of a suitable coupling 20. Mounted in said longitudinal bearings 16,'so as to extend across the front of said bevel gear 19 is a longitudinal shaft 21. 'Loosely'mounted on said shaft 21 is a bevel pinion 22, which is retained in position by collars 23 and 24,-so as to remain in mesh with one side of Said bevel gear 19. In like manner, loosely mounted on said shaft 21 is another bevel pinion 25, which is retained in position by collars 26 and 27, so as to, remain in mesh with the opposite side of bevel gear 19-. Saidbevel pinion-22 is provided at its inner end with female clutch jaws 2,2", preferably formed as an integral part of said pinion; and, in like manner, said bevel pinion 25 is provided at its inner end with female clutch .jaws 25. Slidably mounted upon said shaft 21, intermediate the clutch jaws of the respective bevel pinions above described, is a clutch member-28, provided at its respective ends with male clutch jaws 22 and 25 adapted,aupon proper shifting of said clutch member from one side to the other, to have'ilts clutch jaws 22 operatively engaged with the clutch jaws 22 of said pinion 22, or its clutch j aws 25" operatively engaged withthe clutch jaws 25 of said pinion 25, so that said bevel gear 19,.and consequently the ironing roll and associated rotary parts, may be'rotated in either direction at the will of the opera- Said clutch member 28 while movable longitudinally or slidably upon said shaft 21 is keyed thereto by the spline 29, so that 'rotary movement of said shaft is imparted thereto. Said clutch member 28 is provided, intermediate its clutch aws, with an annular groove or channel in which is engaged an embracing yoke or slip collar 30, having diametrically a-lined andoppositely projecting pivot studs 31, to which are pivotally related the ends of a fork-arm 32 of a shiftlever 33. Said shift-lever 33 is suitably pivoted upon a cross-bar ,34 mounted upon said standards or supports 14. J ournaled in bearing-s 35, mounted near the lower ends of certain of said standards or supports 14, is a transverse rock-shaft 36, to which is fixed an upwardly projecting lever-arm 37, the upper free end of which is interconnected with the lower free end of said shift-lever 33 by means-of link 37 Also secured upon said rock-shaft 36, in a suitable location, is a forwardly projecting pedal-lever 38,

The means for driving the transmission 'mechanism above described, comprises a longitudinal lower or jack shaft 39, journaled in suitably disposed bearings 40 supported transverse cross bars 41 connected with sald standards or supports '14. Fixed on one end of said jack shaft 39 is a. driving pulley 42. Fixed upon the opposite end of said jack shaft 39 is a pulley 43, over which runs a belt 44 adapted to transmit power to said shaft 21 through the pulley 45 mounted on the latter. Said jack-shaft driving pulley 42 may be drivenfrom any suitable source of power, but a very desirable and convenient arrangement of-power source is found in providing an electric motor 46, mounted upon a platform '47 supported at the upper end of said standards or supports 14, and the pulley 48 of which drives a belt 49 which, runs over said driving pulley 42. In order to drive the transmission mechanism at de sired speed, the sizes of the respective pulleys 42, 43 and 45 may be arranged to provide the desired speed reduction from "the 7 motor.

In'practice I have found it desirable that the shift lever 33 be normally and automaticalily retained in a position to, engage .the jaws 22"" of the clutch member28 with the jaws 22 of pinion 22, whereby the normal arrangement of the transmission mechanism is such, that the ironing roll and associated mechanism iso-perated in. a direction and manner" tending; to move the ironing board 8 in the direction of the arrow w. To 'thisend a pull-spring 50 is interconnected between the lower end of the shift lever 33 and a stationary .point provided by one of the-transversecross-bars 41 of said standards or supports 14.. By this arrangement, the

pedal-lever 38 is normally and automatically raised when released from the foot of the operator. When it is desired to reverse the operation of the transmission mechanism, to reverse the rotation of the ironing roll and associated parts, whereby the ironing board 8 is caused to travel in an opposite or return direction, that is in the direction of the arrow y, thentheoperator depresses :the v pedal-lever 38, whereby the rock-shaft is rocked, and the lever arm 37 thrown so as to pull forward the lower end of the shift lever 33, against the tension of the pull spring 50, thereby causing the shifting of the clutch member 28 so as to remove the sam'efrom operative engagement with the pinion 22,

and shift the same so that its clutch jaws 25" operatively engage the jaws "25 of said pinion 25. (This latter position of the parts is illustrated in Figure 1 of the drawings, in which the pedal-lever is shown thus depressed.)

In operation the ironing-board 8 and its ironing roll 4 and impulsion roller 11. The operator W lays upon the surface of "the ironing board the articles to be ironed, and

carriage 7 is normally occupyinga position forward of and out of engagement with the is engaged by the ironing roll 4. Since the clutch devices of the transmission mecha nism are in normal initial positions, as above described, the said ironing roll and impulsion roller will be rotated in opposite directions, so that as they engage the ironing board and carriage they will operatively feed the same rearward whereby the ironing board with the articles to be ironed thereon, passes beneath the ironing roll, so that the articles are engaged thereby and smoothly ironed, the impulsion roller at the same time exerting an upward pressure whereby the articles are submitted to a rolling pressure exerted by the ironing roll. While no means is shown in the drawings for heating the ironing roll 4, such features being no part of this invention, it will be understood that said ironing roll 4 is usually heated by some convenient means. When the ironing board 8 has been thus fed rearwardly a sufficient distance to entirely carry the articles to be ironed beneath the ironing roll a, the operator depresses with his foot the pedal-lever 38, thereby throwing the shift-lever to move the clutch devices into engagement with the pinion 25, whereby the action of the transmission mechanism is reversed, in a manner already described, and as will be clearly understood from an inspection of the drawings, so that the ironing board 8 and its carriage 7 will be caused to travel in a forward or return direction, until it again occupies its normal initial position, ready for repetition of the above described operations.

I am aware that some changes may be made in the arrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, without departing from the scope of my present invention as set forth in the foregoing specification, and as defined in the appended claims. Hence, I do not limit my invention to the exact arrangements and combinations of the said devices and parts as described in said specification, nor doI confine myself to the exact details of the construction of said parts as illustrated in.

the accompanying drawings.

I claim prising a supporting frame-work, a driven shaft mounted on said frame-work, a coupling means for operatively connecting said driven shaft to the ironing. machine, a driven bevel gear on said shaft, a driving shaft supported by saidframe-work in front of said driven bevel gear, bevel pinions loosely mounted on said driving shaft to respectively mesh with opposite sides of said driven bevel gear, each bevel pinion having clutch jaws, a shiftable clutch-member keyed on said driving shaft intermediate said clutch-jaws, a power source comprising an electric motor supported by said frame-work, a speed reduction transmission means intermediate said motor and said driving shaft, and means for actuating said clutch-member to engage one or the other of said bevel pinions.
