SPECIFICATION forming part of Letters Patent No. 461,796, dated October 20, 1891. Application tiled June 26, 1890. 'Serial No. 356.844. (No model.)
To all whom t may concern.-
.Be it known that I, FRANK H. MARSH, a citizen of the United States, residing at Newark, in the eounty'of Essex and State of New Jersey, have invented certain new and useful Improvements 1n Pneumatic Tools, of which plete understanding of the present improvem'ents'and the operation of the tool.
The objects of my invention are to provide an improved construction of throttle by means of which the speed of the tool may be regulated and controlled, and also to furnish a simple and secure fastening for said throttle; to provide an improved form of jacket-catch whereby the jacket may be firmly held in place upon the cylinder and yet quickly removed therefrom; to so construct and locate the spring-latch that it will securely lock the nose upon the cylinder and will not be liable to breakage under ordinary wear; to provide the valve with ends or heads so interlocked that they will not work loose and drop out, and to improve the details of construction, that the tool may bemore serviceable and less liable to wear.
A still further object of my invention is to so construct the tool that it maybe used with a spindle or the latter dispensed with and the striker caused to operate directly on the bit or chisel.
The invention consists in the various features of construction and arrangement of parts, as will be hereinafter more fully described, and pointed out in the claims.
In the drawings, Figure 1 is a-vertical sectional elevation of a pneumatic tool embodying my improvements.' Fig. 2 is a transverse section on the line :r of Fig. 1. Fig. 3 is a section on the line y y. Fig. Ltis a section on the line zz. Fig. 5 is a detail sectional view illustrating the means employed for preventing the entire rotation of the throttle. Fig. G is a detail vertical sectional elevation showing the spindle and spring dispensed with and the bit or chisel in position for the striker to operate directly upon the same.
Fig. 7 is a sectional view of the valve. Fig.
8 is a modification.
Similar letters of reference indicate like parts in all the views. Referring to the drawings, A represents the cylinder; B, the jacket; C, the nose; D, the
piston; E, the washer-sleeve, and F the split washer, constructed, arranged, and operating in a manner substantially similar to thatdescribed in the patent before referred to.
G designates the throttle, which is arranged upon the beveled upper end a. of the cylinder A and adapted to open or close the exhaustpassage b. This throttle G is provided with a series of outlet openings b', graduated in size, any one of which openings may be -caused to register with the exhaust-passage h, and thereby regulate and control the speed of the tool, the larger opening permitting the tool to run at full speed and the others in any desired proportion thereof. The throttle is held in its adjusted position when open by means of a pin c, seated in an-opening in the cylinder A and forced upwardly by means of a small spiral spring (l, bearing against its inner end. The outer end of this pin is beveled and is designed-to engage any one of a series of indentations e, arranged in my improved/tool on the plane illustrated by inner face of the throttle G, so that when the throttle is turned the springactuated pin will engage one of said openingsand hold the throttle-locked in an open position. Vhen the throttle is closed, the operation of the tool is stopped, and consequently there is no jarring.
Therefore it is not necessary to provide any means whatever to lock the throttle in said closed position. To prevent the rotation of the throttle in either' direction farther than is necessary to open and close the exhaustpassage l), the cylinder A is provided with a projectionf, which works in a short groove or channel g on the inner face of the throttle,
movement of the latter in either direction A being-limited by the'stop-pin abut-ting against the ends of said groove g. It may be desirable to provide the exhaust-outlet in the form of an elongated tapering slot, as shown in Fig. S. Hence I do not limitmyself to the arrangement of graduated openings herein shown and described.
It will be seen that by the construction IOO above described I am enabled to run the tool at full speed or any proportion thereof de-4 sired without the necessity oi' lingering the exhaust or the bother of diminishing the power by partially turning ott the stop-cock on the air-supply pipe, which may be located at a distance from the point where the tool is being operated.
The throttle is provided a short distance from its upper end with an interior annular shoulder ZL, which forms a seat for a spiral spring t7. The throttle nut j is interiorly threaded and engages the threaded portionj of the extensionj2 of the cylinder-A, and when screwed down into position forces the spiral spring within the upper end ot the throttle, thusholdingthelatteriirmlyon its seat and yet allowing its ready movement. The threaded portion j is provided on opposite sides with cuts or grooves js and the nut y', formed with passages or openings jiji and on its inner face with groovcsj, corresponding to those on the extension j2. The nutjl is locked upon the threaded extension by means 01": a U- shaped bail or staplejl, the ends of which pass through the openings jij and are bent down in cavities in the nut, provided for the same, to prevent its detachment. rlhe bail or staple engages the grooves in the threaded extension and nut, thereby Dositivelylocking the latter in place. In the cylinder A, preferably just below Jthe throttle, is provided an elongated opening Zu, the inner end of which is circular. A small spiral spring Zt is seated in the circular portion ot' said opening, as shown.
I-I represents a catch,whieh lits in the opening Zt and has a seat 7a2 in one end to receive the spring Zt. The catch II is slightly reduced at its other end, thereby forming a shoulder. The jacket B is formed with a perforation k3, through which the reduced end of the catch Il projects, thus holding said jacket in position against any longitudinal movement whatever. It will be noticed by making the opening Zi: elongated that the catch H is allowed a slight lateral Inovement. This construction has been found advantageous from the fact that the jacket is driven on the cylinder very tightly, and unless the opening in the jacket was brought into perfect alignment with the catch Il when the jacket was first started ou, the catch could not engage said opening, thus necessitating the removal of the jacket and another attempt to register the opening with the catch. By making the opening elongated a slight movement is allowed the outer end of the catch, and the latter in most cases engages the opening in the jacket at the tirst attempt to drive said jacket on.
The nose C is provided near its upper end with an annular ledge or shoulder Z, which, when the nose is screwed in place upon the cylinder A, abuts against the lower end of the latter. A vertical passage or opening Z is provided in the nose,extending downwardly from theshoulder, and this opening Z registers with a vertical opening Z2 in the lower end of the cylinder when the nose and cylinder are screwed together.
I represents a latclrpinavhich is located in the opening Z in the nose, and bearing against the lower end of said latch-pin I is a spiral spring Z3. A finger hold or piece Z'1 projects outwardly from the latch-piu and works 1n an elongated opening Z5 in the nose. The tinger-eatch Z4 is secured in place as follows: The latclrpin is provided with aver-tical passage Z5, extending from its lower end and out of the side of the catch-pin on an incline. rP he spring is introduced in the opening Z', the wire finger-piece placed in position in said opening, and the opening in the latch-pin placed over said wire. The latch-pin is then forced down on the wire, causing the latter to project out through the inclined portion of the opening Z and` then cut off to proper size, the other end of the wire resting on the bottom of the opening Z. In this way a convenient fingerpiece is provided and the latch-pin held 1n place in the opening. The upper end of the latch-pin engages the opening in the cylinder and its end bears against the end of said' opening, thus preventing the linger catch Z4 from engaging the ends of the opening Z". This is essential, since the rapid vibration of the tool would break said finger-catch olf in a short time it' it contacted with the end of the opening Z5 while the tool was in operation. B y locating the spring-latch in the nose a latch-pin of larger size can be employed than by locating it in the cylinder and without increasing the size of stock employedin the cylinder.
.I represents a valve, which is located in a passage m, extending transversely through the piston D and adapted to open and close the air induction and exhaust ports at proper intervals. The valve moves transverse] yin said passage, and its movement is so extremely rapid that its ends must be provided with heads K ot' a material sui'liciently hard to stand the extremely rapid contact with the sides of the eylinderA and yet possess suicient elasticity to prevent wear to the latter. The material found best adapted for the valveheads is vulcanized liber; but much diiiiculty has been experienced in securing these heads to withstand the rapid contact mentioned. To obviate this diiiicultyI provide the valveheads with teats n, which lit in a passage n in the valve. One of these teats is provided with an opening n2 in its end and the end of the other teat reduced to engage the latter. The valve-heads are permanently secured at the point of connection by filling the opening n? with cement. The heads K are tightly fitted in chambers n3 in the ends of the valve., as shown. The walls of the chambers n3 are slightly beveled, so that as the fiber expands the heads will be more firmly held.
The piston D is provided with a d ownwardly-extended integral striker D which 1s IOO IIO
provided with a beveled lower end o. The
vBy making a tapering shoulder on the split washer and slightly tapering the bore of the cylinder the latter is not burredkat the junctvure of the cylinder and split-washer'shoulders.
In some classes of work it is desirable to d1spense with the spindle L and its spring L', and in lieu thereof the* nose C is provided with a bushing M, having a shoulderp, which rests upon an interior shoulder p of the nose. Thlsbushing is driven to position in the-nose and 1ts lower end projects beyond the lower end of the nose. The bit orchisel is inserted through the bushing, so that its upper end will be struck by the striker direct. The bit or chisel receives the full force of the blow, and the work is livelier in appearance than when the spindle and spring are employed. It also permits of the immediate substitution of a sharp bit for one that has become .dulled 1n use.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
