Application February 8, 1943, Serial No. 475,115
2 Claims.
This invention relates to improvements in a sleeve puller and more particularly to a device to pull or extract sleeves of internal combustion engine blocks, bearing mountings, and equivalent locations, although the invention may have other uses and purposes as will be apparent to one skilled in the art.
In the past, difflculty has been experienced in removing sleeves from various locations, especially in the removal of sleeves forming the cylinder wall in an internal combustion engine block. The difllculty in removal of a cylinder or engine block sleeve was prevalent whether the sleeve was of the so-called wet type or the so-called dry type, such dimculty being greater in connection with a dry type sleeve, that is, where the sleeve was in contact throughout its entire outer surface with a cast wall in the engine block, and the cooling fluid of the engine came in contact with the block wall but not in direct contact with the sleeve. In practically all instances of which I am aware, sleeves were withdrawn, especially from engine blocks, by an apparatus operable by means of a hand lever in the nature of a wrench, and the apparatus operated upon the principle of a screw-threaded jack. This process was slow and tedious, involving considerable time on the part of an operator to remove ,the sleeves. In repairing an internal combustion engine, one of the major cost features is the labor charge, and withdrawal of engine sleeves in the past required an objectionable amount of labor and consequently an objectionably high charge for the complete repair operation.
With the foregoing in mind, it is an important object of the instant invention to provide a sleeve pulling mechanism which is easily operable, and which may beused to pull a sleeve in an extremely short time; in some instances, the pulling operation requiring only ten to fifteen seconds after the pulling device has been mounted in position.
Another object of the invention is the provision of a sleeve pulling device which is hand manipulable by only one operator, in a free and easy manner, much more simple than the actuation of a laterally movable lever in the manner of a wrench.
Still another object of the invention is the provision of a sleeve pulling device which operates with greater rapidity than devices of this purpose known heretofore, and which may be mounted in position for the removal of a sleeve with equal or less facility than devices for this purpose known heretofore.
It is also a feature of this invention to provide incorporates a manually operable reciprocable I hammer for actuation against a head or anvil in order to withdraw a sleeve from its mounting.
Also an object of the invention is the provision of a sleeve pulling device which is extremely simple in construction, light in weight, easily transportable from place to place, and which is readily adaptable for pulling substantially any sleeve regardless of the location of that sleeve.
While some of the more salient features, characteristics and advantages of the instant invention have been above pointed out, others will become apparent from the following disclosures, taken in conjunction with the accompanying drawing, in which:
Figure 1 is a fragmentary vertical sectional view, with parts shown in elevation, of a sleeve pulling device embodying principles of the instant invention, showing the same in operative engagement with the sleeve;
Figure 2 is a bottom plan sectional view of the structure of Figure 1, taken substantially as indicated by the line II-II of Figure 1, looking in the direction of the arrows; and
Figure 3 is a part sectional, part elevational view, showing the sleeve holder of Figures 1 and 2 mounted in position ready to begin the operation of withdrawing a cylinder sleeve from an internal combustion engine block, the operation of the sleeve puller being indicated in dotted lines.
As shown on the drawing:
With reference more particularly to Figure 3, it will be seen that the illustrated embodiment of the instant invention is shown, by way of an example of the use of the invention, in position to pull a sleeve from an internal combustion engine block or crankcase 5. The engine head and crankcase pan have been removed before the application of the sleeve pulling device. The engine includes a plurality of cylinder defining walls -6, each of which has a water jacket I therearound. A sleeve 8 is press fitted in the cylinder wall, and a piston operates inside the sleeve. In the illustrated instance the sleeve is of the so-called dry type, that is, the fluid circulating through the water jacket I never comes in contact with the sleeve but only with the integral engine block wall'surrounding the sleeve.
It will be appreciated that the use of the device in connection with the pulling of a sleeve from an internal combustion engine block is only one example of the uses of the device, it being equally as adaptable for pulling bearing sleeves and sleeves disposed in other locations in mechanical apparatus.
With reference more particularly to Figures 1 and 2, it will be seen that the illustrated embodiment of the invention includes an elongated bolt, generally indicated by numeral 9, and having its shank smooth in the upper portion as indicated at I and threaded in the lower sleeve engaging part thereof as indicated at H. The upper end of the bolt 9 carries a preferably integral anvil or head l2.
A pulling plate i3 is slidable over the threaded part II of the bolt shank, and this plate is preferably shouldered adjacent its circumference as indicated at H to accommodate the sleeve to be pulled. The plate is centrally apertured as indicated at with an aperture of greater diameter than the threaded part H of the bolt.
At the upper end of the threaded portion another plate IB may be disposed, this plate being in the nature of'a compression plate, and being stepped inwardly on its underface to provide a succession of shoulders as indicated at I! so the plate is already adapted for use with a number of sleeves of different diameter. The upper plate I6 is likewise provided with a bore in excess of the outer diameter of the threaded portion ll of the bolt so that the plate is freely slidable along the bolt. A nut l8 may be threaded onto the lower end of the bolt to hold the bottom plate 13 in position and provide the necessary pull for the removal of the sleeve. Likewise, a nut l9 holds the upper plate tightly down on top of the sleeve, and it is preferably by means of the nut l9 that both plates are brought into tight coopative association with the sleeve.
Around the smooth shank portion ID of the bolt 9 a reciprocal hammer is disposed, this hammer also being provided with a center bore 2| in excess of the outside diameter of the bolt. The downward movement of the hammer 20 is, of course, limited by the upper nut l9, and the upward movement of this hammer is limited by the anvil or head l2 on the bolt.
In operation, the instant invention is extremely simple. Assuming, for example, it is desired to withdraw a sleeve from an engine block in the manner illustrated in Figure 3. After the engine head and crankcase pan have been removed, the top plate I6 is slid over the threaded portion of the bolt up to the nut l9, and then the bolt is extended through the sleeve to be drawn. The bottom pull plate I3 is then slid over the lower end of the bolt, and the nut l8 applied until it contacts the plate l3. This application of the nut i8 may be by the fingers of the operator only. After the application of the nut ill, a wrench may be used on the top nut 89 to bring both sleeves l3 and I6 into tight positive engagement with the sleeve. After the device has been tightly engaged with the sleeve, in the position illustrated in Figures 1 and 3, it is a simple expedient for the operator to grasp the hammer 20 with his hand and jerk it smartly upwardly against the anvil or head l2 of the bolt, as indicated by dotted lines in Figure 3,'and a comparatively few such jars by the hammer will be sufllcient to draw the sleeve from the engine block. Such operation is materially faster than with formerly known sleeve pullers of which I am aware. Frequently, it requires only between ten and twenty seconds to fully draw the sleeve from the engine block, and the saving in labor is a substantial item.
It will be noted that the upper plate I6 accommodates any one of variously sized sleeves. In view of the fact that the bottom sleeve 13 or the puller sleeve must travel through the bore of the engine block along with the sleeve being drawn, this plate is preferably of an outside diameter very slightly less than the outside diameter of the sleeve. Accordingly, it is more advisable to use differently sized plates I3 for differently sized sleeves, and to this end, the entire device may be provided equipped with as many pull sleeves I3 as there are steps on the upper compression sleeve 16. It is a simple expedient for the operator to select a puller plate of the proper size for the particular sleeve to be drawn.
From the foregoing, it is apparent that I have provided a novel sleeve pulling device which is extremely simple to use, positive in its action, and which will draw a sleeve in an extremely short time. It will further be noted that the device is readily portable, adjustable for accommodating sleeves of various sizes, economical not only to manufacture but also to use, and highly durable.
It will, of course, be understood that various details of construction may be varied through a wide range without departing from the principles of this invention and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
I claim as my invention:
1. In a sleeve puller, an elongated bolt, having a shank of which the upper part is smooth and the lower part is threaded, a sleeve engaging pulling plate at the lower end of the bolt. a nut to hold said plate in position, a plate to engage the upper end of a sleeve to be pulled, a nut to tighten down on said upper plate and clamp the sleeve between said plates, a head on the upper end of said bolt, and a hammer slidable along the smooth part of the bolt shank between the upper nut and said head.
2. In a sleeve puller, an elongated bolt, having a shank of which the upper part is smooth and the lower part is threaded, a sleeve engaging pulling plate at the lower end of the bolt, a nut to hold said plate in position, a plate to engage the upper end of a sleeve to be pulled, a nut to tighten down on said upper plate and clamp the sleeve between said plates, a head on the upper end of said bolt, and a hammer slidable along the smooth part of the bolt shank between the up per nut and said head, said plates being freely slidable over said bolt and each said plate being circumferentially shouldered to engage an end of said sleeve.
