JOHN W. IBRACKEN, 0F LAKLAND, FLORIDA.
ENGINE-enana. v
To all whom 'it may concern:
Be it knownl that I, Jol-IN W. BRACKEN, a citizen of the United States, residing at Lakeland, in the county of Polk andState of Florida, have invented new and useful Improvements in Engine-Cranks, of-which the following is a specification.
This invention relates to an improved crank mechanism particularly adaptable for hydro-carbon engines.
The objectof the invention is the provision of means for increasing the power from the same piston travel and not to increase tliecrank travel and also to prevent back kicks common in internal combustion en ines.
Further objects of the invention wi l appear as the specific description which folows is read in connection with the accomform a part of this application, and in which:
Figure 1 is a top plan view of my imhorizontal engine of the hydro-carbon ty e. Fig. 2 is a longitudinal section on the line 2-2 of Fig. 1. Fig. 3 is a transverse section on the line 3 3 of Fig. 1.
Referring more particularly to the drawing 1 represents the engine bed upon which the cylinder 2 is mounted having the ordinary piston head arranged therein which is connected to the usual piston rod 4. Journaled in the engine bed is the main shaft 5 which is in. two parts and has its inner ends plates 6 having grooves on their oppositer edges as at .7 to
receive the ribs lof the crank arms 8 and 12.
one end with a wrist These crank arms are connected directly at pin 9 secured as is usual to the piston rod 4 and passes through the crank arms and is rigidly connected to straps 10 and 13 which surround the stationary disks 11 and 14 keyed to the engine frame in any suitable manner. Both of the straps are provided with internal peripheral grooves `w iich are engaged-by peripheral ribs on each of the disks so as to prevent lateral displacement. The main shaft passes eccentrically through the disks 1 1 and 14 below the horizontal position of the piston rod so that at the time of admission of the charge in the cylinder, the crank arms 8v and 12 will be atan incline to the line of travel of the piston inthe direction of its rotation so that a back kick is impossible.
Specication of Letters Patent. Patented June y2(1), 1911. Application led April 20, 1910.- Seiial No. 556,495.
' Keyed to the main shaft on the outside of the engine bed are small pinions 15 which mesh with larger gears 16 keyed to a countershaft 17 which is journaled in the engine bed as at 18 beyond the throw of the cranks. These gears neutralize any side strain u on the main shaft and balance the action w en the load is on one side of the shaft only and thereby prevent wear on the wrist pin.
By eliminating one of the cranks and making the crank pin an ordinary stub shaft or wrist pin, it will be seen how the device lmay be applied to a one-side crank, or side at an angle'to the piston rod so that when the piston receives the impetus of the expanded gases, the crank will be driven in its proper direction and not inthe reverse direction, which causes the back kick on the starting ever.
' a Having thus described the invention, what I In a device of the class described, the combination of a reciprocating member of a two part driving shaft, stationary disks surrounding the ends oi"l the driving shaft and mounted eceeiitrilcally'thereto, uiding members keyed to the ends of the driving shaft, cranks slidably mounted upon said guiding members and adapted to rotate the same, a pair of sleeves surrounding the stationary disks, a wrist pin having its ends keyed to the sleeves and having the cranks and reciprocating member journaled thereon,l a balanceshaft and an inter-geared connection between each end of the 'balance shaft and the respective ends of the driving shaft.
In testimony whereof I ailix niy signature in' presence of two witnesses.
JOHN W. BRACKEN.-
