July 7,1959 T. P. AVERETTE SHEEP FOOT TAMPER Filed Feb. 10. 1956 moms R AVERETTE IN V EN TOR.
14/ lorngy United States Patent G SHEEP FOOT TAMPER Thomas P. Averette, Van Nuys, Calif.
Application February 10, 1956, Serial No. 564,694
3 Claims. (Cl. 94-48) My invention relates to tampers of the sheep foot type comprising a shank welded onto a cylindrical metallic roller, and a tamping foot having detachable engagement with the shank to permit removal of the foot so that when it becomes worn it can be replaced or repaired.
It is the main purpose of myinvention to provide a sheep foot tamper that embodies a structure by which the foot can be securely locked in fixed position on the shank, and yet readily detachable from the shank when desiring to repair or replace the foot.
It is also a purpose of my invention to provide a sheep foot tamper ofthis. type characterized by the shank, as welded on the roller, being formed in its outer end with a tapered socket, a'tamper'foot having an integral stem received in the socket and similarly tapered, and a pin extendable through the shank and the socket and so engageable with the stem as to draw it into frictional wedge engagement with the socket and to lock it therein against withdrawal or turning. Additionally, the locking pin is provided with a portion which can be bent to engage an outer portion of the shank in a manner to prevent accidental withdrawal of the pin, such pin portion being shearable to permit detachment thereof and thus allow removal of the pin incident to the removal of the stem from the socket when replacing a worn tamper foot with a new one, or when repairing the worn foot.
It is also a purpose of my invention to provide in a sheep foot tamper of this type, a releasing tool which, when driven into the shank functions to release the stem in relation to the socket so as to allow ready removal of the foot from the shank when required once the locking pin is removed.
With the foregoing purposes in view, together with such other purposes and advantages as may subsequently appear, I will describe only one form of sheep foot tamper embodying my invention, and will then point out the novel features thereof in claims.
In the accompanying drawings:
Fig. 1 is an exploded view showing the shank and foot of the tamper in perspective.
Fig. 2 is an elevational view partly in vertical section, showing the parts of the tamper assembled and locked together by the locking pin.
Fig. 3 is a fragmentary vertical sectional view taken on the line 3-3 of Fig. 2, and in addition showing in broken lines the stem releasing tool in position for actuation to release the stern.
Fig. 4 is an enlarged fragmentary sectional View similar to Fig. 2 but with the locking pin removed, and showing the releasing tool applied to release the stem incident to removal of the foot from the shank.
Fig. 5 is a detailed perspective view of the locking pin.
Fig. 6 is a fragmentary end elevational view of a tamping roller showing it equipped with the sheep foot tampers embodying my invention.
Referring more particularly to the drawings, the shank of the sheep foot tamper is indicated generally at A, and
the demountable tamper foot element at B. The shank A is preferably formed of ductile cast steel so that it is rendered subject to being readily mounted on the periphery of a metal cylindrical roller C as indicated in Fig. 6 by a weld joint. The foot element B may be formed of heat-treated cast steel to render it resistant to abrasive wear.
The shank A comprises an elongated tapered body 10 which may be of rectangular form in cross section as illustrated, or it may be round. In either event, it is uniformly tapered from end to end, and its large end has a concave bearing surface 10a which conforms in curvature to the periphery of the roller C to which it is welded. In the smaller end of the body 10 a socket 11 is formed which extends downwardly into the body for a distance approximately one-half of its length. This socket is on a slight taper from end to end. Spaced upwardly from the lower end of the socket 11, an opening 12 is formed transversely in the body 10 which is intersected by the socket (see Figs. 2 and 4). Below the opening 12, and so as to intersect the socket 11 at its lower end, is a second opening 13 that parallels the opening 12.
The tamper foot element B comprises a foot 14 which may be of the rectangular form shown, or in the general form of a foot, and a stem 15 fixed on the underside of the foot, such stern being circular in cross section and tapered to conform to the taper of the socket 11 so that it can be completely extended thereinto as intended to cause the foot to seat on the end of the body 10.
A groove 16 that is rounded transversely except at its lower side where it is flattened as indicated at 16a, is formed transversely in the stem 15 at a point along its length such that when the stem is inserted in the socket 11 it comes into alignment with the opening 12, that is, it bridges the parts of such opening so that the latter is made continuousfrom end to end to receive therein a locking pin P.
The pin P is of circular form for a portion of its length adjacent the head or striking end 17 thereof, and then flattened at one side and tapered to its opposite end to form a wedge 18. The length of pin P exceeds that of the opening 12 for a purpose to be described hereinafter.
A releasing tool T is provided for forcing the stem 15 free of the socket 11 incident to removal of the foot 14 from the shank body 10, and this tool comprises a straight shank having a non-circular portion 19, and a rounded portion 20 tapering into a pointed end portion 21.
In the application and operation of my invention, the shanks A are aflixed to the outer periphery of the roller C to project radially therefrom, by welding the concave surfaces 10a to the circumferential surface of the roller. After so affixing each shank to the roller, the foot B is applied to the outer end of the shank by inserting the stem 15 into the socket and to the position shown in Fig. 2, it being understood that the stem is so positioned circumferentially that the groove 16 is aligned with the opening 12.
This operation is succeeded by driving the locking pin P into the opening 12 with its flat side 18 lowermost so that it engages the flat side 16a of the groove 16. The resultant action of the wedge 18 operates to draw the stem 15 into frictional wedge engagement with the wall of the socket 11, and thus the foot 14 is drawn into contract with the shank body 10 and firmly held in proper position thereon.
In the final position of the pin P a portion 18a thereof projects from one side of the body 10 as shown in broken lines in Fig. 2. This portion can, by the use of a hammer, be bent downwardly to the right angular position shown in solid lines to repose within a recess 10b in the body 10.
With the pin P secured in place as described, it functions to maintain the stem in frictional wedge engagement with the socket to hold the foot 14 against turning on the shank, as well as accidental detachment thereof from the shank, the bent end portion 18a of the pin serving to lock the pin against accidental displacement from the opening 12. V
In the event it becomes necessary to remove the foot 14 from the shank body either for the purpose .of replacement or repair of the foot, such removal can be readily efiected and without the necessity of driving the foot outwardly from the shank, which is extremely difficult..
First the pin P is removed by cutting the end portion 18a therefrom through the use of a hammer and chisel, when the pin can be driven from the opening 12 by a suitable tool, say the tool T. This is followed by partly inserting the tool T, pointed end first, into the opening 13, and then driving it to the position shown in Fig. 4, whereby the tapered portion 20 acts against the lower end of the stem 15 to lift the stem and free it from the socket 11. Thus by now gripping and pulling upwardly on the foot 14, the stem is removed from the socket for repair of the foot, or to allow a new foot and stem to be applied to the shank.
Although I have herein shown and described only one form of sheep foot tamper embodying my invention, it is to be understood that various changes and modifications may be made therein without departing from the spirit of the invention and the spirit and scope of the appended claims.
What -I claim is:
1. A sheep foot tamper, including: a shank one end of which is suitable for welding onto a cylindrical metallic roller, and the other end of which is fiat, the shank having a tapered socket axially therein with its large and entrance end in said fiat end; a tarnping foot having one side thereof flat and symmetrical with said flat end of the shank; a tapered stern fixed at its large end to said side of said foot and received in the socket, said stern adjacent its inner end having a transverse groove therein one wall of which is flattened; said shank having a transverse opening therethrough aligned with said groove; and a locking pin removably fitted in said opening and said groove, said pin having a flattened and tapered side engaging said flattened wall for drawing said stem into frictional wedge engagement with the socket.
