J. MARTIN BRICKLAYER'S HAMMER Filed April 9. 1927 Inventor JhfiW War Z Patented Nov. 8, 19.27.
JOHN MARTIN, OF EARKERSBURG, WEST VIRGINIA.
BRICKLAYER S HAMMER;
Application filed April 9,
The present invention relates to improvements in bricklayer-s hammers and has reference mo're particularly to a simple and efficient means for securing the handle to the head of a hammer.
One of the important objects of the present invention is to provide a tool handle fastening which is of such construction as to permit the handle to be readily and easily attached or detached with respect to the head of the hammer, means being-provided for rigidly securing the handle to the head so that the same cannotbecome accidentally disengaged therefrom while in use such as frequently results with the type of tool handle fastenings now generally employed for connecting a handle to a hammerhead.
A further object of the invention is to provide a tool handle fastening of the above mentioned character which issimple in con struction, inexpensive, and furthermore adapted to the purposes for which the same is designed.
Other objects a-ndadvantages of this invention will become apparent during the course of the following description.
In the accompanying drawing forming part of this specification and in which like numerals are employed to designate like parts throughout the same:
Figure 1 is a View partly in elevation and partly in section of a bricklayefis hammer embodying my invention showing the tool handle fastening means associated therewith.
Figure 2 is a vertical sectional view-taken approximately on the line 22 of Figure 1 for more clearly disclosing the cooperating means between the handle and the hammer head for preventing the lateral sliding movement of the handle with respect to the head,
Figure 3 is a sectional view taken'approximately on the line 33 of Figure 1, and
Figure 4 is a sectional view through the block carrying rod or shank showing the rotatable and slidable upper section of the handle in top plan. 1
In the. drawing wherein for the purpose of illustration is shown the preferred embodiment of my inventiointhe numeral 1 designates the head of a bricklayers hammer, the handle being designated generally by the numeral 2. Formed on one face of the head 1 adjacent the headed end thereof are the spaced transversely extending lugs and 1 respectively. The inner opposed sides of 1927. Serial No. 182,415.
these lugs are tapered whereby to form a substantially dovetailed recess 5 in said face of t e head 1 and the purpose thereof will be presently apparent. Each lug is formed with a recess at 6 in the outer face thereof and this is clearly shown in Figure l of the drawing.
The handle 2 includes the provision of an elongated rod or shank 7 which is externally threaded at its respective ends. The handle further includes the sections 8 and 9 respectively, and each of these sections is formed witha longitudinally extending bore to accommodate the elongated rod or shank 7. The outer end of the outermost section 9 has its bore enlarged and fitted therein is the elongated sleeve 10, the same being formed at its outer end with enlargedbase 11 which engages the outer end of the section 9.
The sleeve 10 is internally threaded as illustrated at 12 and the outer threaded end of therod 7 is threaded into this sleeve in the manner clearly shown in Figure 1. The inner end of the outermost section 9 is reduced as illustrated at 18 while the outer end of the sectionnearest the tool has its bore enlarged to accommodate the reduced portion 13 so that the-outer end of the section 8 will abut the shoulder 14 formed at the juncture of the section 9 with the reduced portion 13 when the section nearest the tool is in its outermost position on the rod or shank 7.
This section 8 is adapted for rotatable as well as longitudinal slidable movement on the inner portion of the rod or shank 7 for a purpose to be presently described. The inner portion of this section 8 is enlarged to provide the head 15'and this head is provided with a pair of diametrically opposed flat faces in a manner more clearly shown in Figures 1 and 4c of the drawing. Formed on the face of this enlarged head 15 at diametrically opposite points are the projections 16 and the purpose of these projections is to provide a means for cooperation with the slots 6' formed in the outer faces of the lugs 3 and 4 as will be also presently described.
A flat faced block 1.? is formed with a threaded socket in one face thereof to receive the inner threaded end of the rod or shank 7 whereby said block will be carried by the inner end of the rod or shank and the sides of this block are tapered so that the same is substantially dove-tailed in cross section as is clearly disclosed in Figure 1.
handle.
In assembling the hammer, the section 9 of the handle is rotated so as to cause said sections to move outwardly on the shank or rod 7 and this is done until the free ends of the projections 16 formed on the face of the enlarged head 15 on the free end of the inner section 8 of the handle are disposed outwardly of the outer face of the dove-talled block 17. lThe dove-tailed block 17 is then free to he slid laterally between the lugs 3 and 4; of the hammer head 1 whereby said dove-tailed block 17 will fit in the dovetailed recess 5 provided therefor by the cooperating lugs 3 and 4t.
After the block has been properly positioned in the recess, the section of the handle nearest the tool is then rotated until the projections 16 are in alinement with the slots 6 formed in the faces of the lugs. The section 8 is then moved inwardly on the shank so that said projections will enter the respective slots and the inner faces of the projections are beveled for cooperation with the adjacent beveled sides of the tapered block 17. The outermost section 9 is then rotated in a reverse direction for moving said section inwardly on the shank so that the inner end of the outermost section will engage the outer end of the innermost section and thereby lock the latter against ment. WVhen the parts are thus arranged, the projections 16 will cooperate with the sides of the slots 6 formed in the lugs to prevent the handle and i from being accidentally moved laterally with the dove-tailed block respect to the head 1 and thereby, the dovetailed head will be held in locked engagement within the dove-tailed recess 5 thus providing a positive connection between the handle 2 and the hammer head 1. The hammer may then be used in the usual manner and there will be no possibility of the handle becoming accilentally disengaged from the hammer iea Whenever it becomes necessary to dis-assemble the parts of the hammer, the outer- I most section 9 of the handle 2 is rotated so' that the same will move outwardly a sufficient distance on the rod or shank 7 to permit the innermost section 8 to also move on the rod whereby the projections will be disengaged from the notches or slots formed in the lugs and the dove-tailed block 17 may then be moved laterally out of engagement with the dove-tailed recess 5.
It will thus be seen from the foregoing description, that I have provided a tool handle fastening for use principally in connection with bricklayers hammers although the same may be used in connection with any other type of tool embodying a head and a This tool handle fastening will at all times be positive and eflicientin carrying out the purposes for which it is designed and furthermore, due to its simplicity, it may be longitudinal movereadily and easily actuated for dis-assembling the parts of the hammer or tool with out the loss of any considerable length of time or labor.
\Vhile I have shown thepreferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit or sacrificing any of the advantages of the appended claims.
