Appncanon meaaprn 12, i917. serial no. 161,438.
To all whom it may concern.'
Be it known that we, ALBERT F. SoHRoE- DER and RALPH R. Roo'r, both citizens of the United States of America, residing at 1250 WV. 76th st., city of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful improvement in Manifolds, of which the followings is a specification, the principle of the invention being herein explained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.
Our invention relates to a manifold such as is in common use today in automobiles and more particularly to a manifold formed of more than one part and having the edges ofthe parts/secured by what is known as a lock seam joint,l wherein one edge is bent or folded about another and thereafter the two laminated or tightly compressed.
W'e are well aware that such lock seam joints have longbeen in common use, indeed, the same has been employed for sealing the ends of tubes. We believe however, that the application of such idea to the manufactureof a manifold having angularly presented branches is patentably new; bearing in mind the peculiarity of having all the defining edges so secured together.
Adverting to the drawings:
Figure lf is a perspective view of amanifold embodying our invention.
Fig. II is an end view of the same.
Fig. IH is a section thereof showing the complementary parts presented ready for the first operation. v
Fig. lV is a view corresponding to Fig. II following the completion ofthe first operation.
Fig. V is a similar view after the completion of the second operation and also'showing on one side a slightly modined result of such second operation.
Fig. VI is also a section illustrating the final form of the lock seam joint.
Fig. VH is a perspective view of one portion .of the manifold showing a completed cornerv formation.
rlhe manifold comprises a trunk 1 having branches each designated by the numeral 2.
According to the exemplification of the drawings the manifold is formed of only two parts which are substantially halves 3 and Il respectively. As shown the halves are of, approximately semi-circular cross section. The part 3 has along one side a continuous flat flange 5 and along the other a series of fourseparated flat flanges 6 which are of various' contour to form the four branches of the manifold and are all designated by the numeral 6. The other part 4l has edges formed as hooked flanges. Along one side a continuous iiange 7 is formed, while on the-other side a series of four separated hooked flanges are similarly all designated as 8. The contour of the flange 7 and of the flanges 8 corresponds to that of the flange and the flanges 6 respectively. rlhe flanges 7 and 8 are of greater width than the flanges 5 and 6 to the outline overall of which they are adapted to conform. rlhis enables them to be bent and folded around the latter respectively, the progressive steps in the operation being clearly indicated in Figs. 'LII to Vl. Finally spot welding is resorted to after the completion of the final operation of the series disclosed in the drawings, this welding operation along the lock seam being adequate to insure the tightness of fit and strength which is required.
We claimz- A manifold adapted for use in internal combustion aircraft. engines comprising a hollow structure shaped to form a. main passageway and a plurality of branches extending therefrom to form corners, said manifold being manufactured of complementary light sheet metal portions having continuous integral flat flanges around each of said corners as well as therebetween to constitute abutting edge portions, the latter being laminated, folded and welded together whereby to form lock seams capable of maintaining a near vacuum within the manifold and sustaining both the high temperatures and the high pressures. 19gned by us, this 30th day of March,
