Specification of Letters Patent.
Patented Aug. 29, 1916.
Application filed May 4, 1916. Serial No. 95,407.
To all whom it may concern:
Be it known that I, JOHN E. DAVIS, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Motors, of which the following is a specification.
My invention relates to motors designed for light work in which a reciprocating piston is to be driven by air or other fluid pressure; its object being to lessen cost and increase efficiency.
To this end, it consists in the construction and arrangement of a removable cylinder in connection with a supporting frame having apertures constituting a practical extension of the cylinder bore in which the cylinder element is seated and held by screw plugs; and in which frame and plugs the receiving and exhaust passages are formed; and in the further construction and arrangement of the valve and connecting parts.
In the present illustration, in view of the numerous special uses to which the principle of construction can be applied, requiring more or less variation in details, I have shown the motor as adapted to the use of bunch makers in cigar manufacture, to be secured upon the bunch makers table to drive the cutters in preparing the wrapper leaf to size preparatory to receiving the filler.
In the drawings herewith, are shown in Figure 1, a front elevation of the motor as adapted to use in connection with a bunch makers table; Fig. 2, an under plan View of the supporting frame and cylinders; Fig. 3, a cross-section taken through the cylinder sockets and connecting passages of the frame near the inner side of one of the end walls of the frame; Fig. 4, a longitudinal elevation in section of one of the cylinders and its connecting passages taken on the line mw of Fig. 3; and Fig. 5, alternative form of stuffing box.
Referring now to the drawings, A designates a rectangular box-shaped frame, preferably of cast metal, closed at top, sides and ends, but entirely open at the bottom and provided at the bottom with a lateral flange, a, by which it may be secured by screws or bolts to a table, T. In the opposite end walls are formed hollow bosses, a (front) and a (rear) (Fig. 2), at each end of the frame, which bosses are bored in exact fore and aft alinement in pairs longitudinally opposite, and these apertures are threaded. Cast or formed in or upon the inner side of each of the end walls of the frame A are passages a (4*, connecting the hollow interiors of the bosses, a 03 respectively, with outlets a a". Extending between the end walls of the casing and seated at its ends respectively in each pair a c of bosses is inserted a section of pipe to constitute a work ing cylinder, B. The cylinder thus formed is held in place and closed by cylindrical plugs 6 b 6 (Fig. 4), exteriorly threaded to engage the corresponding interior threads of the hollow bosses and cored with passages 6 6*, to register with the passages a a respectively, to admit the motor fluid to the interior of the cylinders 13. The plug Z1 also has an oil passage b fitted with a screw plug 72 The cylinders are provided with working pistons P whose piston-rods are carried through the forward plug 72 and a suitable stufling box either of the ordinary type as shown Z2 in Fig. 4, or made as shown in Fig. 5. That plugs 5 6 are formed with external flanges as shown afiording the usual shoulder for packing, as shown in Fig. 4.
The outlets, a a", are connected at each side by a pipe C (Fig. 4) with a central rotary valve or fourway cock D, by which motor fluid is admitted alternately to opposite ends of the cylinders B from a source of supply (not shown) through a supply pipe C The exhaust is discharged through a corresponding pipe C The valve is operated through a rod or other connection (not shown) with the crank arm cl of the valve structure D.
In Fig. 1, showing the motor adapted to operation in connection with a bunch makers table, the outer ends of the piston rods, P, engage in carriers E in which are j ournaled disk cutters, e, acting against the surface of table T. These cutters are protected by the usual shields, s, and the carriers are preferably connected across by a brace f to insure uniformity of action.
It will be observed that the location and arrangement of the bosses, a a upon and through opposite sides of the rectangular frame A greatly facilitate the boring and finishing of the same in exact and perfect alinement at one operation. This construction also allows screw plugs seated in the bosses and cored for admission ports, to be used as cylinder heads; and a section of standard tubing to be used as the working cylinder. The structure complete is therefore rigid, perfectly alined, and the parts completely within and protected by the cover; and is made expeditiously and at very low cost.
The principle of construction described renders it possible at a relatively low cost to produce an efficient motor whose working cylinder or cylinders, made of standard tubing, can be at any time renewed; while at the same time the alinement is perfectly secured and maintained. For this purpose alone, the frame need be only rectangular in one dimension; but by making it as herein shown a complete cover, the cylinders are perfectly protected against injury and at the same time jacketed for artificial warmth if needed.
By the use of four-way or other standard cocks, the problem of cheap construction is further simplified.
I claim as my invention and desire to secure by Letters Patent of the United States:
1. In a reciprocating motor, in combination with a containing frame having parallel front and rear walls provided with opposite bosses cylindrically hollow in the same axial line, a hollow cylinder seated at its ends in said bosses, and removable plugs seated in the bosses bearing inwardly against and forming the end closures of the cylinder.
2. In a reciprocating motor of the character indicated, in combination with the containing frame with hollow bosses, said frame having passages formed therein extending into the hollow of the bosses; and plug closures of the bosses formed with corresponding passages extending to the interior of the cylinder.
3. The combination of a covering frame having front and rear walls provided with hollow bosses; connecting passages formed in the frame walls, extending through the shells of the bosses; a cylinder shell seated at its ends in the opposite bosses between the front and rear walls of the frame; screw plugs entering the bosses from the outer end,
provided with extension passages and bear ing at eachend, respectively, of the cylinder shell; and a centrally arranged operating valve connected at each side with the frame passages.
In testimony whereof I have hereunto set my hand in presence of two subscribing wit nesses.
JOHN E. DAVIS.
