BUTT FOR SAND RAMMERS.
Specification of Letters Patent.
Patented May 16, 1922.
Application filed August 2, 1920. Serial No. 4.005199.
To all whom it may concern."
Hammers, of which the following is a specification.
My invention relates to improvements in rammers such as sand rammers and has more particular relation to the lmtt of such tool and method of making the same. The object thercoi? is to provide a butt of simple and light construction and one which is moreover very efiicient and durable considering the character of the Work done.
In the d a'wings Fig. 1 is an elevation oi a sand rammer butt embodying my invention; Fig. 2 asection on the line 2-2 of Fig. 1; Fig. 3 a view illustrating the mode of operation of producing the butt; Fig. 4 a plan view of the die; and Fig. 5 a plan view of the metal disk in its original shape as used in the die.
Referring to the present embodiment of my invention as herein shown the butt comprises a body portion 1 which in practice is made very light and consequently I prefer to employ aluminum as the material and make the same hollow thereby providing a large central chamber 2. This body cylindrical at its lower or outer end and is truncated coni cal at its upper end with the result that there no chance of lodgment of sand upon any portion thereof which would be liable to be thrown back in the face of the operator dur ingthe ramming operation.
Inasmuch light material such. as aluminum is comparatively soft and not sufficient ly durable to withstand the impact of the butt against sand, etc., I provide the body with an end cap of hard material. such as thin sheet steel which is applied thereto in the following novel manner.
Tlhe extreme lower or outer end of the butt slightly reduced in diameter as compared with the main body of the butt as indicated at 3, the difi'erence equaling the thickness of the sheet metal plate or disk 4 which is applied thereto. Between these two diameters of the butt there is provided a circumferential greet e5 adapted to receive the flange 6 of the disk in the manner now to he err-- plained.
In practice the d hi 4: with its upstanding; marginal flange 6 n gplied to the hut in a. single operation. through the medium of the die 7. As shown in Fin. 3 the disk is laid in the die with its margin resting upon the shoulder 8 of such die. The butt which is secured to any suitable pressure means as power press is forced directly downwardly with. the result that the disk l: is turned and wrapped around the corners oi the butt and the flange G is forced into the groove 5. It will be umlerstood that the die provided with a circular socket 9 into which the disk and the lower end oi? the butt forced in this operation.
According to this construction. the butt is made very light and is provided with durable end or cap and moreover such cap is so applied thereto as to become practically an integral part 01" the butt. Moreover the steel. cap when worn out can be readiiyreplaced thereby prolonging the life of the butt.
I claim:
1. A sand rammer butt comprising;- a body made oi? a light soft material and a samarate end made of sheet metal.
2. A sand rammer butt comprising a body made of aluminum and a separate end of sheet metal secured to such body.
3. A. sand rammcr butt comprising a hol low body of aluminum having" a t: ential groove near iss enter one rate end of sheet m t directed flange rec 4:. A. sand ramm which is cylindr.v cated conical at inner metal end applied to the cylimih end of such body.
A sand rammer butt coluprisimr a body which is cylindrical with its extreme outer end reduced slightly in. diameter and which has a circumferential groove at the junction of the two diameters, and a disk of: sheet metal applied to the end oi such body and the reduced diameter thereof, said disk having a marginal flange received by said groove.
