To all to ham it may concern Be it known that I, JoHNsron TURNER, a subject of the King of Great Britain and Ireland, and residing at 28 Plumpers Road, Sheflield, in the county of York, Eng land, have invented certain new and useful Improvements in or Relating to Dowels, of which the following is a specification.
This invention relates to dowels, that is to say, devices adapted to be'secured to one part and to project into engagement with a recess or socket in another part for the purpose of retaining the two parts in correct relation to each other. The invention is particularly useful for connecting the parts of wooden patterns and core boxes or for connecting patterns or parts thereof to pattern-supporting devices, such as the pattern plates of moulding machines, but is not limited to such use.
A hollow drawn dowel-pin has been proposed comprising a cylindrical dowel portion closed at its outer end and provided at its open end with four long angular prongs. The prongs were forced into one part and marking of the counterpart was effected by pressing the closed outer ends of the dowels against the counterpart to cause small caps onthe outer ends of the dowels to make depressions in the counterpart.
The object of the present invention is to provide an improved dowel and with this end in view the invention consists in a dowel comprising a body portion having an axial bore extending therethrough and small prongs for temporarily securing the body portion in position and extending laterally of and beyond one end of the body portion, in combination with a headed screw or pin, the point of which is adapted to project from the pronged end, the head of the screw or pin being adapted to engage the opposite end of the body so as firmly to secure the body, after it has been temporarily positioned by means of the prongs.
Referring now to the accompanying drawings Figure 1 is a plan view of a form of improved dowel;
Figure 2 is a sectional view on line A-A of Figure land showing the dowel in use on a core box or the like, and
Figure 3 is a sectional elevation of a slightly modified form of the improved dowel.
the body 1 is shown at 3.

are shown as claws projecting slightly outwardly and beyond the end of member 1. ltwlll be understood that any suitable number of prongs may be employed. A suitable form of screws; for coroperating with The screw 3 preferably hasa rounded head 4: which is of the same diameter as the outer periphery of the body 1, and an unthreaded portion 5 of substantially the same length and diameter as the aperture of the body 1.
It will be understood that the body portion and screw may be made of any Suitable metal, preferably iron or brass.
The body portion may be made to suit any of the standard sizes of headed screws. The form of prong or claw illustrated in Figures 1 and 2 is suitable for dowels of the smaller sizes.
A slightly modified form of prong is shown at 6 in Figure 3, in which the prongs are formed entirely beyond the end surface 7 of the body portion, so as to allow the prongs of the dowel to be forced entirely below the surface of the material of the core box or the like. This form of prong is especially suitable for the larger sizes of dowel.
The improved dowel is put into position as follows A recess or bore 8 is made in the edge face of one part 10 of, for example, a core box, and a metal socket 9 is driven into recess in the usual manner. The dowel is intro duced into the recess 8. The second part or half 11 is now positioned in the desired relation with respect to the part 10, and the two parts of the box are forced towards each other by pressing or hammering. The prongs 2 are thus caused to enter the material of part 11 of the box. When the part 10 of the box is removed from the part 11, the dowel, being now secured to the part 11, leaves the recess or socket 8 in the part 10, and the dowel may then be secured in position by the screw 3.
By loosely inserting the dowel in one part and then transferring it to the co-operating part of the box in the manner above described, all risk is eliminated 0f the two ing to the fact that the prongs hold the v parts being out of correct alignment or re lation with each other when the dowels are brought into engagement with their respective sockets.
If desired the body portion may' be countersunk at bothendsy and the screw-head shaped to fit the countersunk recess at the upper end of the body.
With the present invention patterns are not mutiliated with centre bit holes and are more readily attached to a pattern-plate owdowels in position until they are secured by the screws.
It will be understood that any suitable size or shape of body piece and screw may be employed.
Having now described my invention, what I claim as new and desire to secure by Letters Patent is l. A dowel comprising a body portion hav- I ing an axial bore extending therethrough and small prongs for temporarily securing the body portion in position and extending screw or pin engaging the opposite end of the body so as firmly to seourethe body after it has been temporarily positioned by means of the prongs. V
2. A device asclaimed in claim 1, wherein the prongs are formed entirely beyond the 7 plane of the end surface of the body portion,
whereby said prongs maybe forced entirely belowthe surface of the member to which the dowel is applied.
In testimony whereof I have signed my name to this specification.
