Application filed July 19, 1912. Serial No. 710,515.
Specification of Letters Patent.
Patented Oct. 21,1913.
To all whom it may concern? Be it known that. I, HUGH H. WHITEl-IEAD, a citizen of the United States, residing at A.. 1 Maria, in the county of Manatee and State of Florida, have invented a new and useful Mechanical Movement, of which the following is a specification.
The present invention relates to improvements in mechanical movements, the primary object of the invention being the provision of means to convert a reciprocatory movement of the piston rod of an engine in which the usual form of crank shaftis disper 'ed th, and a rotary movement in a l a itut nai shaft which is provided with the usual fly wheel, thus providing a means whereby the main driving shaft containing;
the fly wheel is rotated constantly in the desired direction and has imparted thereto any number of revolutions without regard to the number of reciprocations of the piston rod.
A further object of the present invention is the provision of a novel means whereby the rotation of the shaft may be readily reversed without interfering with the reciproeating movement of the piston rod.
Vfith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can he made within the scope of What is claimed without departing from the spirit of the invention.
In the drawingsFigure 1 is a longitudinal sectional view through the complete engine. Fig. 2 is a section taken on line 2-2 of Fig. 1. Fig. 3 is a section on line 3-3 of Fig. 1. Fig. 4 is an enlarged sectional View through the ratchet gears for operating the spiral shaft. Fig. 5 is a detail view in top plan of the two gears, their carrying frame and the shaft. Fig. 6 is a detail view of one of the ponds for locking its gear against rotation.
Referring to the drawings, the numerals 1 and l designate the respective cylinders of the engine which as shown, are disposed horizontally and have mounted therein, the
.11, the rod 20 is provided with a hand grip 6 and extends through the elongated slot 7 of the engine casing C. lower end of the rod forked as at 8, the purpose of which wiii presently appear; Disposed upon the re spective inner faces of the cylinders and in the path to engage the rod 5, are the two spring cushions 9 and 9, which act as a cushioning means at the end of each respec' tive stroke of the pistons 2 and 2'.
Mounted upon the base 10 are the two bearings 10 in which are journaled the main driven shaft 11 of the engine. The shaft is provided centrally of its length as clearly shown in Fig. 1, with the two sets of spiral grooves 12 and 13. Mounted upon one .end of the shaft 11, is the fly wheel i l-l,
while disposed 'ir sliding movement about the grooved p .ion of the shaft is a frame or casing 15. This frame or casing 15 is connected rigidly to and is moved with the rod 5, the same being disposed within the forked end 8 of the said rod 5, as clearly shown in Fig. 2. The-two gears or ratchet Wheels 16-17, are mounted upon the spiral portion of the shaft 11, one of which is pro vided with the rib 18 fittin in the spiral 12, and the other of which is provided with the rib 19 fitting in the spiral 13 (Fig. 4-). These gears are permitted normally to rotate, but it is desired that one shaft shall be rigid relatively to the carrying frame 15, while the other is free, and vice versa; and, in order to accomplish this the rod 20 is mounted in ports 2121', and by means of the handle 22, the rod may be oscillated. Keyed upon the rod 20 and within and slidable with the casing 15, are the two pawls 23 and 24, which extend in opposite directions, one above each of gears or Wheels 16 and 17, respectively. Thus by the manipulation of the rod 20, the pawl 23 is placed in engagement with the gear 16, and the pawl 24 is released from the gear 17. When in this position the reciprocation of the frame, with the gear 16, locked, will rotate the shaft 11 in one direction; and should it be. desired to reverse the rotation of the shaft oscillated in the opposite direction to place the pawl 24 in engagement with the gear 17 and to release the pawl 23 from the gear 16. The gears 16 and 17 are provided with ball bearings 25 to reduce the friction at the wearing surfaces. It is also evident that a single way rotatingshaft may be employed and that only one r G would he used, thus di.--:pensing w the rod 20 and then having: a single pawl liaeh of the respeclire cylinders l and l l are provided with the carhureted air admitting port 36 at the base of each of the respective cylinders, the same being so disposed that upon the out-stroke of either one of the power pistons 2-2, a charge of carhureted air Will be drawn into the cylinder and upon the explosive stroke will be ejected through the port 38 into the chamber 39 and finally through the port 40 into the combustion ehain iler 41 of the cylinder 1 or 1. The spark plug 42 is so timed as to explode the comp!" :l (1 charge at the desired highest of compression so that the burned will no expelled through the exhaust port 45 of the respecti e cylinders l and 1. l
From the foregoing description, taken in l connection with the drawings it is evident that by means of the mechanism connected to the shaft ll and actuated by the rod 3 of the two power pistons Q---2', that the desired rotation will he imparted to the shaft 11 and that the stroke of the resy'leei ive pistons 2 or i 2' rnav be increased to any degree so that a pluralsty of rotations to each reciprocation. will he imparted to the shaft 1.1 and not a single TOtflt'iOll as is the case where the pisi tons are connected to a crank shaft. through a piston rod as is the usual custom.
It is also evident that by means of the mechanism controlled by the levers at the toe shaft 11 may base, that the rotation of be reversed at any time the reciprocation of the i of the :ngine without alleeting power pistons.
lVhat is claimed is:
A mechanical movement, including a rceiprocatory rod, a longitudinally disposed rotatable shaft mounted pa allel with said rod. said shaft having two spiral grooves intermediate of its ends. an arm eonneeted to the reciproratory roll and extending toward the shaft. a frame rarried upon one end of said arm and surrounding the shaft, two ratchet wheels mounted in said frame and having the teeth thereof disposed in opposite directi ns. each of said ratchet. wheels heing'providwl with :1 lug disposed to it within the respective grooves of the shaft, a manually oscillated rod disposed parallel to the grooved shaft, and two oppositely dis posed pa \vls slidahly keyed upon the rod and within the Maine, whereby either pawl is placed into engagement with its respective ratchet wheel :lor locking one wheel at a time against rotation.
In test-inony that I claim the foregoing as n1 own, I have. hereto aflixed my signature in the presence of two witnesses.
