3 Claims.
This machine relates to devices used in connection with reboring, or otherwise refinishing the cylinders of motors, particularly such cylinders as are arranged in multiple, mounted on blocks to drive vehicles.
The main object of the invention is to provide a combined collecting and discharging device whereby chips, grit/dust and other debris resulting from such operations, is prevented from entering the bearings of the crank shaft, cam shaft, etc., and conducted outwardly beyond points that might be damaged.
A further feature is in the provision of a simple, compact and easily operated debris discharger, that effectually avoids the damaging ef- [sets of boring chips and the like.
Another purpose is to produce an implement that can be easily installed from the top of the cylinder block and removed when the work is done; is operative with or without displacement of the crank shaft whether of plain conventional type or counterbalanced type and in no way interferes with the refinishing mechanism or its operation.
These important purposes are accomplished by the novel construction and arrangement of parts hereinafter described and illustrated in the accompanying drawings, constituting an essential part of this disclosure, and in which:
Figure 1 is a partial side elevational, partial longitudinal sectional view of an embodiment of the apparatus, showing its application.
Figure 2 is a fragmentary sectional view of the removable centering device used in applying the apparatus.
Figure 3 is a sectional view of the apparatus as passed through the cylinder and seated on the crank shaft with the cutter about to complete its operation.
Figure 4 is a side elevational view of a modified form of the device as entering into the cylinder.
Figure 5 is a similar view of the same, showing the flexible receiver as expanded and pressed upwardly against the end of the cylinder.
Referring in greater detail to the drawings, one of a series of cylinders, such as are used in connection with an internal cumbustion motor for various power purposes, is designated generally by the numeral l5, and the crank shaft 16.
It is well known that such cylinders wear un equally throughout their length and also become out of round to the extent that fuel waste and other losses occur after a period of use.
When this condition becomes manifest recourse is had to some form of interior refinishing,
usually by a power driven boring bar l'l provided with a cutter I8, held in a tool holder l9.
It is well understood that all particles removed by cutters, grinding, and other like operations and their lubricant, must be prevented from entering the crank shaft and other bearings, to which such dust and debris are ruinous.
This is accomplished in the present disclosure nuts 24, between which is clamped a guide ring support sleeve 25, its upper portion enlarged to present a shoulder against which abuts an interchangeable guide ring 26 selected in conformity with the diameter of the cylinder to be refinished, and having inreaching nipples 21 to pass through grooves 28 lengthwise in the sleeve 25 and engage in an annular recess 29 at their inner ends.
'A sleeve 30 is secured on the lower portion of the stem 20 by a pin 3|, this sleeve having an enlarged bore containing threads 32 and is bevelled at its lower end, to act in the manner of a socket wrench in properly locating the chip receiving appliance.
Engageable by the sleeve threads is the upper end of a tube 33 into which the bevelled end 22 of the stem enters, and also the point [9' of the tool holder when the cutter has completed its operation, as seen in Figure3.
This tube has a plurality of longitudinal chip receiving openings 34, and is provided with a flange or shoulder 33 of suchlength as may be required and on which are seated spacer rings-35 selected in length with reference to the diameter of the cylinder, for reasons further on explained, these spacers supporting an annular funnel base 36.
Mounted on this base is a funnel 31 selected in accordance with the bore of the cylinder containing a narrow groove 38 disposed at a convergent angle and in which is secured the lower edge of a flexible skirt 39, as rubber, its upper expanded rim portion adapted to contract by curling inwardly as it is passed through the bore of a cylinder and thereafter expand so that its Ill) (iii
edge extends outwardly therebyond, constituting a cup to collect the debris at the cylinder bottom.
The tube 33 is encircled by a coiled compression spring it arranged to urge the skirt and its support firmly upward, the lower end of the spring seated on a tubular extension M and connected by a pin 52 limitedly movable in a slot 43 in the extension.
The extension 4! is pressed downwardly by the spring .0, and terminates in a saddle 46 shaped to straddle the throws of the crank shaft I5, while its upper opposed angular surfaces are adapted to receive detritus delivered through the tube 33 and discharge the same from either side through openings 4|.
Surrounding the extension M is a sleeve 45 which prevents detritus from being discharged through the slots 43, and also serves the purpose of holding the pin 42 in position.
In the event that dismantling becomes necessary, as for instance in substituting a longer or shorter tube 33, the sleeve is moved upwardly, over the spring 40, to allow the pin 2 to be removed.
In the modification shown in Figures 4 and 5, the tube 33 is cut angularly on two opposite sides, presenting openings 58, for the discharge of debris, and in a central projection 5! on the lower portion 53 of the tube, is fixed a solid plug 54 having acute angled faces 55 to divert the debris outwardly.
The tube slidably extends into a sleeve 55 in which are opposed slots 5.! guiding and limiting the movement of a pin 58 fixed in the tube.
Fixed in the lower end of the tube 56 is a tubular plug 59 having its lower end tit shaped to engage the surface in which it may be placed.
Interposed between the plug 59 and bottom of the tube 53 is a coiled spring ii I, operative to press the skirt upwardly and the plug downwardly to the limit of the length of the slot 51.
It will be understood that various lengths of tubes 33, spacers 35 and extension plugs 59 may be used as required.
In operation the centering device constituting a socket wrench is attached to the upper extending end of the tube 33, and the collecting appliance pressed through the cylinder.
A guide ring 26, selected as appropriate to the diameter of the cylinder, is inserted, centering the appliance, and upon its being settled in proper location, the centering device is released and wholly removed to permit entrance and operationof the refinishing tool.
When this has been done all chips, debris and lubricating material used drops. on the funnel skirt 39, thence through the opening 34, through the tube 33 and eventually is directed by the upwardly disposed angular element of the saddle 6 to pass outwardly through openings 4i thereabove where they may be collected and removed in any convenient manner.
As the cutter I8 completes its operation, the
the cylinder, the skirt or flexible portion 39 of the funnel folding downwardly over the edge of rigid, interchangeable element 31 of the funnel, and as it is drawn through the cylinder, its bore is wiped clean.
Although the foregoing is descriptive of the preferred embodiment of the invention, it will be apparent that minor changes may be made in its construction, without the exercise of invention or conflicting with the scope of the claims hereto appended.
Having, thus described the invention, what is claimed as new and desired to secure by Letters Patent, is:
l. A cylinder refinishing debris collecting and discharging device, comprising a flexible no-rrnally funnel shaped inverted skirt, a ring to guide said skirt into a cylinder to be refinished, said skirt expansible when passed through the cylinder, a manually operable spindle having a sleeve on which said ring is interchangeably engaged, a. rigid hollow collector head to which said skirt is fixed at its bottom, means combined with said spindle to extract said head, a cylindrical tube engaged in said head and provided with orifices for the entrance of debris, said tube having opposed discharge ports in its lower portion, a sleeve slidably surrounding the lower portion of said tube, a compression spring coiled around said tube to urge said head carried skirt against the cylinder, and means to support the device carried by the last named sleeve.
2. In a waste conductor for use in reboring cylinders and passable therethrough, in combination with a boring bar having a cutter, an integral elastic funnel capable of rim expansion and contraction, a spring pressed tubular support for said funnel having a footing to rest upon a surface, spacers intermediate the length of said support, said support being depressed by said bar when the cutter has advanced through the cylinder, and means on said bar to centralize said support coincidently with such depression.
3. In a waste receiver movable through an upright cylinder to be re'bored, and a boring bar having a cutter, an integral elastic inverted funi nel having a rim of larger diameter than that of the cylinder, a spring pressed hollow support for said funnel having a footing to seat upon a surface, and a conical axial point on said bar to enter said support thereby to assure the support and funnel to be centrally positioned when the cutter has completed its operation.
