Specification of Letters Patent.
Patented July 21, 1908.
Application sied February 2o, 1905. serial No. 246,477.
To all lwhom it concern:
Be it known that I, GEORGE B. PICKOP, a citizen of the United States, residing at New Britain, county of Hartford, and State of Connecticut, have invented certain new and useful Improvements in Vibrators,"of which the following is a full, clear, and exact description.
' My invention relatesV to improvements in vibrators, sometimes called vibrator engines, among the main objects being simplicity, economy of construction, durability, and re# liability of action.
f In the drawings Figure l is a side eleva/- tion. 3 is a section on the line )I X looking in the direction of the' arrows. Fig. 4 is a section on the line Ye-Y looking inthe direction of the arrows. Fig. 5 is a sectionon theline E Z looking/in the direction'of the arrows.
In the drawings I have shown and will'now proceed to describe the preferable form of my invention. i Y.
1 is a cylinder having a plain vstraight bore therethrough.
2 2 are screw plugs whereby the ends of the cylinder l may be closed. i
when the piston is in either of its extreme positions.
'el is an air admission passage through which compressed air at the desired ressui'e is supplied to the interior of the cy inder.
5 5a are exhaust ports. ton stands in the position indicated in Figs. l and 3 the exhaust port 5 is open and air will be admitted through the passages d fla, through the groove 3a, and thence through 'the duct 4b to thatend of the cylinder adj acent to the-stop 3C. The pressure of the air iii this ,and of the cylinder will cause the isvton to shift from the,position indicate .in
Figs. l and 3 to lthe position indicated in Fig. 2. This `movement of the piston will open Fig. 2 is a longitudinal section. Fig..
the exhaust port 5 and will close theexhaust pprt 5a and the airducts 4 4b. When the piston is in the position indicated in saidFig.
2,' the groove 3* in the piston willv furnish a communication between the ends of the 'ducts 4 4d, -whereby air will then be admitted to that end of the piston adjacent to the stop 3d. The ressure will then drive the gisten back to its original position indicate vibrates back and forth it will impart sharp blows in rapid succession against' the inner r ends of the lplugs 2 2.
Iv prefer to incline that end of one of the admission ducts, for example 4", where it enters the cylinder, for by so doin I find that it causes the piston to impart as ivhtly stronger blow at one end than at ,the o'tbher, with the `result that the piston will stop .or `come to rest when the air is shut OH, at one end of the cylinder rather than in the middle. Hence,
readily. It`will1be observed that I eliminate .entirely the necessityof any spring or other means for starting or maintaining the vibrator inaction. I preferably form the cylinder of brass or'bronze, and the .piston of steel, properly hardened vand ground. I find by this arrangement most effective results 'can is necessary. This is of great advantage,
time impair the free action of the parts, owin to the fact that it would become ummy and retain particles of dust or dirt, t e presence of which would tend to bind the piston and prevent its free operation. The apparatus as show-n is double acting, althougi this is either or both ends may be modified at will by varying the pressure of the air supply, or
When the pis-v by varying the size of the ports. The field of work for such an apparatus is unlimited. The source of powerA may be compressed air or any other suitable fluid medium. The plugs 2-2 may have squared sockets in their ends, for example as shown in Fig. l, to permit of the introduction of a wrench whereby ysaid plugs may be readily inserted or removed.
The construction is sim ile, inexpensive, durable, and effective, and
in Figs. 1 and 3. As the piston thusY when air is'turned on again, the piston startsv be obtained, and that no lubricant whatever comprises such since the use of aA lubricant would in a short not essential. 'The force of the blows on easilyproduced parts that it requires but little cost to manufacture or maintain.
' scribed,
What claim is:
-1. flfnfa vibrator engine, acyli-nder having an internal bore of uniform`d1arneter, and a duct leading to and piercing one Wall of the b ore at an oblique angle relative to the end Wall, said duct being interrupted intermedi- 'ate its length and communicating with the bore, a solid piston operable in the-bore and haring an extension atone endv of reduced diameter, and an annular recess and' removf able plugs for both ends or" said cylinderl one plug forming said end Wall,
2, In an a paratus of the charaoter dea oyinder, a duet leading to and piercing one end thereof, another duet eom municating With the iirst, and leading to and piercing the opposteend of said cylinder, one of said ducts piercing the cylinder at an oblique angle relatvel to the end Wall of the cylinder, both of said uots being interrupted intermediate their length and each' piercing saidcylinder at two points in the same trans verse plane, 'a piston, and recesses therein arranged lto alternately furnish communicaseaeee' tion between the interrupted portions ef said ducts.
3. In a vibrator engine, a cylinder, an iinperiorate free piston therein7 said piston havL ing two annular grooves intermediate its length, said cylinder having an air-admission port and tWo .air transfer passages leading therefrom to opposite ends oil the cylinder, each passage being located Wholly on one side of said admission port, each passage tapping into the cylinder at three points, two or' said points being located in substantially the same transverse plane, the third point being located ator near the adjacent end er' the cylinder, -saidicylinder also having en;
haust passages independent of the transfer assag'es, and arranged respectively toward the ends of the cylinder, said piston operatlng as a Valve to control all of said passages.
