Specification of Letters Patent.
?a.tented Feb. 27, 1906.V
To all whom it lmay concern:
Be it known that I, ANDREW?. TALLMADGE, a citizen of the United States. residing at Washin ton city, District ol Columbia, have invente certain new and useful Improvements in Gas-Engine Sparkers `and If'do hereby declare the followin to be a full, clear, and exact description o the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to certain improvements in sparkin devices for explosive-engines; and the objects and nature of my invention will be readily understood b thosel skilled-in the art in the light of the following explanation of a construction shown in the accompanying drawings as an exam le from among other arrangements within tlie spirit and scope ofcmy invention.
It might he here stated that an the ,invention is to provide an exce mlysim le improved device which can be rea i y aP novpv in use and 'whereby the sparks can be easily and uickly advanced or the sparking device can e so set as to cause the sparks to occur at the desired time with relation to the movement of the piston.
The invention consists in certain novel features in construction and in arrangements or combinations of arts, as hereinafter more fully set forth anniJ explained.
eferring to the accompanying drawings, Figure 1 is an elevation of the Working parts `of a sparking device including my invention,
the cylinder and other working parts'of the engine not being shown. Fig. 2 1s a detail or detached perspective view of In device or attachment` Fig: 3 is a longitu inal sectional view of the device or attachment shown in Fig. 2. l
My attachment yor device is particularly adapted f or use on thestationary ex lesiveenglne such as disclosed by Unite States Patent No. 7 46,406, issued December 1963, to J. S. Thurman, and in the drawings l'have shown only the connections or means for ac- I tuating the sparking points. In the engine of said patent a sw and reciprocating rod carries a trippingog to periodically trip means for moving the movab e sparki point. This actuating-rod is slidable throngV a rockingor oscillating guideblock Vor head, which practically constitutes the fulcrum for guide-block conied to certain types of explosive-engines Y tains a spring-held` follower" pressedY towardV the .rod to permit outward 'eldin thereof in case of accidental back t row o the'engine; but the block has no means for-shifting the fulcrum-point of the actuating-rod Vfor the purpose of advancin the spark; My attachment is substitute for said oscillatin ide-block of the patent just referred to and is provided with means for changing the fulcrumor position ofl said actuating-rod to vary the time of the spark with respect to the position of the piston of the engine.
'In the drawings, 1 is a. plate secured to the head of the engine-cylinder, (not showin) and this plate carries the rod 3 'projecting into the cylinder to form the stationary sparkin point, and also the rocking shaft 5, Whic Within the cylinder is rovided with the movable sparking point, not showm) coperati'ng with said stationary oint, as in sai patent, to produce the spaiilr on the separation of the two points.
7 is an arm rigid with the rocking shaft 5.
11 is an arm loose on shaft 5 and at one Vend having extension 13, bearing against expansion-spring 14. At its opposite end armll is provided with the projected end or finger 12 and with a lateral extension 17, to the outer end of which retractile spring 18 is secured, the op `osito end of said sprin 18 being secured to t e arm 7 to yieldingly old a lateral projection of said arm 7 a einst the arm 11. The spring 14 yieldingly olds the arms 11 and 7 iny their normal positions, (see Fig. 1,) with the arm 7 against buffer 9 of rigid stud 10. Y
` 22 is the actuating-shaft .for the sparking device, and 20 is the actuating-rod reciprocated and swung by said shaft and at one end having eccentric connection with said shaft throu h the medium of a crankarm and pin 211. he actuatin -rodis provided with the :tripping-dogv 19, )v 'ch has an elliptical path ofmovement and is adapted to engage the projecting end or finger 12 and move the same to contact the sparking points.
`23 is a stud projecti from the plate 1, and 24 is arocki i orpsci ating block mounted to rock on sai stud, any suitable means being provided to confine said` biock on said stud. At one end the block 24 is formed with the journal or boerin hole or npc .125, extending therethroug to receive sai stud 23.
The block is elongated and formed withha longitudinal slidcway open at the opposite sides of the block and closed at its outer end by a plate 26, secured to the ends of the opposite side walls of the block.
27 is a guide-box for the actuating-rod 2O and through which the same reciprocates. This box 27 extends transversely through said slideway of the oscillating block 24 and is loosel confined therein and adjustable longitudinally thereof. This box 27 is prefera ly recessed across its side edges to receive the opposite side walls of the block 24 and to form shoulders fittin .the longitudinal edges of said side walls to ho d the box against transverse movement in the block. The box` Abox 27 longitudinally of the oscillating block to vary the position of the tripping-dog 19 with respect to the rojecting end or finger 12 and to hold or locl said box in the desired position. As an example of means which can be employed for this purpose I show a screw-threaded rod 31 arranged longitudinallyof the block and passing loosely through the late 26 and at its inner end rigid with the ox 27.
32 is a wing-nut at the outerface of late 26 and screwed on the outer end o the threaded rod 31 and by means of which the threaded rod and the box can be moved longitudinally of the oscillating block. 33 is an ex ansive spring coiled around the threaded ro and compressed between the box 27 and the plate 26 to hold the nut 32 and the box in pro er osition and to force the box inwardly of t e s ideway when the nut is unscrewed or loosened.
i If desired, .the late 26 can be formed with a series-of radia grooves or depressions 34 "around the openin for the threaded rod and the nut with a ra ial rib or edge 35 to fit in any one of said grooves, and thereb lock the nut in the desired adjustment an `whereby the adjustment can be more accurately effected and determined as the rib snaps from groove to groove.
In Fig. 1 the box 27 is Ashown adjusted i about to normal osition to cause the engaging end of the tri ping-dog to travel in the elli tical pathindicated by the lower dotted patli' and in the direction of the arrows and so that the dog willengage the finger 12 and swing the same to the left, and thereby swing the arm 7 and brin the movablesparking point into contaht with the xed point and so that the dog will slip past nger 12 about at the dotted line b, and thereby permit the arms and movable point to return to normal position, thereby causing the igniting-spark.
lf the engine speeds up so that it becomes desirable to econoinize fuel and attain maximum power by advancing the spark, it is merely necessary for the operator to turn the nut 32 in a direction to move the box 27 outwardly the desired distance to cause the dog to trip the finger 12 at an earlier point in its path. For instance, the box 27 can be adjusted outwardly to cause the engaging end of the dog to `move in the upper path shown by, dotted lines in Fig. 1, in which the dog will trip at the point a, thereby advancing the spark with respect to the movement of the piston.
lt is obvious that by employing my attachment a wide range of adjustment is provided. for either retarding or advancing the spark to suit various conditions and tnat the construction is exceedingly simple and durable and very easily operated.
The attachment can be applied to various types of engines and can be very readily applied to engines of the Thurman type now in use by simpl substituting my attachment for the guidelock of the Thurman engine.
It is evident` that various changes and modifications might be resorted to in the forms, arrangements, and constructions of the parts described Without departing from the spirit and scope of my invention. Hence I do not wish to limit myself to the exact construction shown.
What I claim is-4 1 As an article of manufacture,ithe sparkadvancer comprising a block adapted to be mounted and rock on a journal and having a longitudinal slideway, a box through which the sparker-actuating rod is adapted to reciprocate, said box confined in said slidewa j, and means for adjusting said box longitu 1- nall of said slideway and holding the same in the desired adjustment, substantially as described.
2. An explosive engine spark advancer com risin a block having a bearing on which the lock 1s adapted to oscillate, a box conlined to and movable longitudinally of said block, said boxhaving a bore through which the sparker-actuatiiig rod reciprocates,- and a threaded ro'd and nut for adjusting said. box and holding the same inthe desired position longitudinally of theblock.
