CRANK-CASE.
Specification of Letters Patent.
Patented May 26, 1914:.
To all whom it may concern:
Be it known that we, S'rnPrmN EVANS ALLEY and ROBERT MoGREeoR, subjects of the King of Great Britain and Ireland, and residents, respectively, of Glasgow, Scotland, and London, England, have invented certain new and useful Improvements in Crank-Cases, of which the following is the specification.
The invention has for its object to provide for vertical inclosed reciprocating engines, compressors, pumps and the like, a single-piece crank-case forming a base, receiving the crank shaft bearings, and forming also an entablature to receive the cylinders or distance piece trunks; the structure being of much better continuity of strength than hitherto usual, and permitting of easy assembly and withdrawal of the crank and of the provision of unusually large inspection doors.
As illustrated in longitudinal section, in sectional end elevation, and in plan in Figures 1, 2 and 3 respectively on an accompanying sheet of explanatory drawings, a crank-case made according to the invention is as a whole of prismatic form, that is to say, it is rectangular in plan with substantially vertical ends A and with sides B sloping inwardly upward. It is formed with a gap 0 centrally along the flat top and the ends to about the level of the bearings of the crank shaft D, thus allowing the crank shaft to be lifted vertically from its bearings and through the crown of the crank case. The seatings E for the lower halves of the crank shaft end bearings are formed upon the end plates contiguously t0 the gapsthe upper halves F are secured in usual manner upon them.
The seatings G for the lower halves of the intermediate bearing are supported upon deep webs H extending up from the base and extending out to the sides and topin fact, webs somewhat similar in contour to the end plates. These vertical webs are reinforced at convenient intervals by webs J at right angles to them, and the outermost of which extend to and reinforce the webs and aperturesand the particular angle 7 of the sides of the case.
What we claim is A one-piece crank case of prismatic form with base flanges apertured to receive securing bolts, said case being gapped along its top and down its ends to permit of the vertical removal of the crank shaft, inwardly extending arcuate flanges at the bottoms of the end gaps to form seatings for the crank shaft end bearings and apertured within the casing to receive securing bolts for the end bearings, end cover plates to close the bearing gaps in the ends of the casing, deep webs intermediate the end plates and approximating the same in contour, arcuate flanges thereon forming seatings for intermediate bearings, reinforcing longitudinal webbing supporting said intermediate webs and end plates, a flat bearer plate on the top of said casing apertured to permit the passage therethrough of connections t0 the crank shaft, the side walls of the casing being apertured to afford inspection apertures, substantially as described.
In testimony whereof we have signed our names to this specification, in the presence of subscribing witnesses.
