Specification of Letters Patent.
' Patented Mar. 3, 19141.
Application filed December 1G. 1911. Serial No. 666,096.
To all. 'ie/mm.. it muy winger/1.'
` Be it known that l, Amun* E. S. Facunnomr, a subject of thel Kingr of Sweden. residing' at Brooklyn.l in the'eounty o't Kings and State ot' New York, have invented new and useful Improvements in Explosive-'Eugincs, of which the followingis a Speciication. i
This invention relates to gas engines and more especially to cylinders for same and where the cylinder is provided with a false head retained 4in place hy spring` pressure but which is adapted to yield when the explosion of the gas takes place as will be more fully described in the following specification, setjtorth in the claim, and illustrated in the drawings, wherein,
Figure 1 is a sectional view of the same, showing the iuiproved head appliedtlieieto.
F i 2 is a similar View at rinht anale to Fig. :1. Fig. 3 is a plan view ofthe yoke .for `Carrying the spring.
The cylinder 5 is of usual construction i and isprovided with the Water jacket to cool samen The spark plug 6 is located on the linetof the highest movement of the piston 7, which is provided with the usual pitman S ,oonnecting it with the crankshaft 9.
The piston Vis dished on its upper side in vorder to provide a chamber betweeny itself andithe false head 10 Which islikewise dished. The piston and the head are vpro-- vided with upwardly projecting studs 12 which pass through a chamber 13 and the .upper end le of the cylinder. They are then connected with a yoke 15 which conforms with the top of the cylinder and has over hanging arms 1G perforated to receive the ends of springs 17. The other ends of these springs 17 areconnected with the frame 1S of the engine by means oi bolts l0 and nuts 20.
At one side of the cylinder is an exhaust port 21 With the usual valve 2Q, which permits the burnt gases to escape in to the. mut'- ler 23. 'The chamber 13 is also connected hy means of an outlet 24 with the mutiler in order to allow the head 10 to move upward and have its movement limited by the spring .17 only. At the other side of the cylinder is a manually operated vent cock 25 to relieve the cylinder o'l any undue accumulation ol exploded gases.
down so as to form a solid head to the cylinder. The springs may he adjusted by means of the bolts 19 and nuts 20 or lighter springs may be substituted as desired.
As illustrated in Fig. a' of the. drawing the piston 7 is arranged so that at one end of its stroke it covers the inner end ol the passage 21.. Therefore the valve 22 located in the passage 2l is relieved ofexecssive pressure when the charge between the piston T and the head 10 isreceiviug its final compres sion and also the said valve Q2- is relieved 'from sudden shock duringr the. initial expansion of the charge immediately after it has heen fired.
What .l claim as new and desire to secure. by Letters lateut is An engine comprising a cylinder provided at its side with an exhaust passage, a piston` slidahly mounted in the cylinder, and arranged to move over thc exhaust passage, a head nlovahly mounted in the cylinder between the exhaust passage and the end of tho cylinder,A studs attached to the head and slidably passing through the end of the cylinder. a. yoke attached to the studs, and springs` f-onneeteril with the yoke and the cylinder and nol'inall)Y holdingl the yok against the end ot'ilie cylinder said studs and yoke arranged to cooperate with the cylinder to limit the movement ol the head in the cylinder to a patti between the exhaust passage and the end ot the cylinder.
In testimony whereotl I atlix my signature in preseueeof two witnesses.
