" Patented June 1.1, 19.12.
Application tiled November 21, 1908, ASeriai No. 468,803. Renewed September29, 1911. Serial No. 651,986. 4 l
Be it known that I', JOHN W. EIsENi-IUTH, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Reversing Mechanisms for Motors, of which the following 'is a specification, reference being had therein to the accompanying drawing.-
This invention relates to motors, andv has specially in View an improved reversing y mechanism therefor in which the reverse of the motor is obtained by manipulating the valves thereof.
Another ob'ect is the provision of an operating sha t for the valve shafts which willturn only in one direction regardless of the'direction in which the motor is turning.
A further object is to provide a construction which will operate positively on the valve shafts and instantaneously set the valves for the direction in-4 which it is desired to have the motor operate.
The deviceis primarily intended for use with hydro-carbon motors of the multiple cylinder type, but it is to be understood, however, that the invention is Vnot to be limited to such application, since, from what will appear later, it can be readily understood how the invention may be applied to other types of engines and motors now in use. For purposes of illustration I have selected a hydro-carbon motor of they com-l pound type, having the cylinders and valve chests oppositely disposed, the crank shaft thereof being at all times in mesh with a vertically disposed shaft which, in turn is4 at all times in mesh with a reversing shaft.
Referring to the acompanying drawings- Figure l isan end elevation of a hydrocarbon motor of the compound type, fitted with the present inventiol. Fig.` 2 is a detail sectional view of the reversing mechanism thereof. Fig. 8 is a side elevation ofa portion of theoperating rod. Fig. 4 is a transverse sectional view taken on the line 4:4, Fig. 2. Fig. 5 is a detail side elevation o f one of the driven gears. Fig. 6 is a detail sectional view taken on the line 6 6, Fig. 1.
Referring to said drawings by numerals, 1 designates the crank clase of a hydrocarbon motor from which the crank shaft 2 proy jects andv carries a gear 3 on-its outer end the motor.' The beveled gears 9 and 10 are i retained in spacedrelation on ther hollow shaft 11 by means of a bushing 12. Referring more particularly to Fig. 2 of the accompanying drawings, it willlbe observed thatthe said`beve1ed gears 9 and 10 are each pro vided with a shouldered hub 13 which loosely t'f'the hollow shaft 11, .and adjacent to each gear, the said hub is provided with a clearance chamber 14. Each hub is pwvided with adiagonally disposed slot 15 one end of which communicat with theelearance chamber 14, thebther end terminating in a longitudinally extending slot 16. The hollow shaft 11 is provided with a longitudinally extending slot 17 adjacent to and co.-
operating with the slotted portion of thev hub, as will presently appear.
A valve shaft operating rod 19 is 'slidable through the hollow shaft l11 and is retained in spaced relation thereto by means of space blocks 20. Said rod is also provided withI locking pins or lugs 21 which' may be carried by one of thespacer blocks, said pins or lugs being arranged on said rod so that they will project through theslots 17 to the shaft 11 and alternately engage with one or the other' of the slots of the hub of thebeveled 0'ears 9 and 10 to lock the same to the sliafl? 11;. The ends of hollow shaft 11 project into gear casings 22 which are supported at opposite sides of the engine or motor by means of J bracket bearings 23 which support the shaft 11 and have mounted thereona Worin or other pinion 24 which is held in meshV with I' a pinion 25 carriedeb the lower end of each of the shafts 26 an 26". ,Onfeend of the rod 19. projects through and beyond one of the gear casings 22, and is provided' with an extension 27 terminating ina ball 28'which is seated in a socket 29 carried bythelowr end of a hand-operated lever 30 which has a bracketconnection 31 'with the motor.
The operation of the` inventionis as fol.
lows: Assuming the parts of the reversing v'of theA engine or motor and causes the crank mechanism to be in the position shown in Fig, 2, it will be seen that oneof the locking pins 21 of -tlie rod 19 is projecting through the slot 17 of the shaft 11 and into the clearance chamber 14 of the hub of t-he beveled pinion 10. The other locking pin isv projecting through the slot 1T of the shaft 11 and the slot 16 of the hub of pinion 9, and, therefore, said pinion 9 is locked to the shaft 11 and imparts its movement thereto, while pinion 10 is turning idly inthe opposite direction on said shaft. To reverse this operation the lever 30 is rocked to impart a sliding movement to rod 19 through the shaft ll, causing the locking pin vwhich has been .holding pinion 9 to the shaft l1 to-move into the clearance chamber of said pinion and simultaneously remove the other locking pin from the clearance chamber of pinion 10 and through the diagonally disposed slot l5 and with the slot l'of the hub of pini'on 10 and the slot 23 of shaft 11, and thereby lock shaft 11 to pinion 10. This movement immediately alters the operation shaft 3 thereof to rotate in an opposite movement, which movement 1s communicated to shaft' 11 through the gears 4, 8 and lO and*I shaftdy It will thus be seen that irrespective of the direction in which the motor is operated the hollow shaft 11 will be rotated inbutl one direction.
