HANDLE ND BLADE connrzorr ou.
Be it known that 1, JOHN S. SURBAUGH, a citizen of the United States, residing at Vinoennes, in the county of Knox and State useful Improvements in Handle and Elad'e Connections, of which the following isa specification, reference being had therein to the accompanying drawmg.
.The present invention relates to handle and blade connections for use in shovels, scoops, spades and other tools, this invention being an improvement over the handleand blade connection disclosed in my Patent No. 1,374,336 granted April 12, 1921.
The invention has 'for its object to improve and simplify the Connection of the handle and blade or head of the tool, permitting either the blade or handle to be removed and replaced when worn out or damaged, thereby providing for economy in that eitherpart of the tool can be replaced without "discarding the remaining sound art. Another object is to provide thoroughly eflicient and convenient means for securing the handle member Within the roll of the blade in a rigid and substantial manner, to withstand prying, torsional, leverage and other strains to which the connection is subjected in use, and the connection being, at the same time, extremely simple and inexpensive. I
A further object is the provision of such a connection utilizing a single securing bolt or fastener for retaining the handle member within the roll and clamping; said parts tightly together by the simple operation of tightening said bolt or member which has a flexing or straightening movement to accomplish such results. v i 5 l Vith the foregoing and other objects in view, which will be apparent as the de scription proceeds, the invention resides in the construction and arrangement of parts hereinafter described and claimed; it'being understood that changes can be made within the scope of what is'cla-imed withoutde- "parting from the spirit of the invention.
The invention is illustrated in the acoom panying drawings, wherein Figure 1 is 2, perspective view of the ments.

member. and blade. 1
Fig. 3 is an enlarged cross section on the line of Fig. 2. a a Fig. 4 is a cross section similar to Fig. showing a mod-ifiation.
' i Fig. 5 is anelevation of'another modified form of bolt or clamping member.- p The unventron can be used in shovels, scoops, spades and other tools,xhav1ng-a through the connection between the handle 3 similar blade, andyas shown, the blade 1 is of the .hollow back type, such as used in shovels and scoops,v said blade being pro vid'ed with an upstruck r0112 extending forwardly from its rear end and the roll, as
shown, has a fork 3 whose branches stiffen and reenforce the body of the blade to make it thoroughly rigid with theroll and back;
the roll 2, being preferably of sheet metal having. its longitudinal edges meeting at tlie'bottom, and said tubular member 4-mav A tubular handle ,member 4 is fitted within be extended to constitute the shank, or a wooden shankor core 5 can be fitted within said-tubular member 4 as illustrated, it being apparent to those versed in the art, that the handle may be composed of ashan k 5 fitted within the tubularmember 4, or may be composed of a tubular metal member, similar to'the member 4, or maybe simply a wooden shank as at 5, without using'the tubular member 4. -T'he construction illustrated, however, is "preferable for several reasons, in that the wooden and surrounding metalmembers reenfoi'ce and stiifenrone another to withstand the strains. The tubu- 'lar member 4 is of a shape to fit snugly unthereof, and is of a length to project rearwardl y from under said roll. Transverse rivets 6* and 7 or other similar securing elements extend through the member 4"and shank 5' for securing them together, the rivet 6 being located near the lower or outer end of the tubular memberyand the rivet 7' at the rear end of the roll: The-ends of the rivets 7 can extend from the tubular member; 4, as disclosed in said patent-, to abut 1 against the rear endof; the roll, as seen inF-ig. 1, whereby to transmit the for-' ward or downward longitudinal strains and strengthen same, as disclosed in said patent, by means of a liner plate 8 arched transversely to fit under and within the roll, and secured thereto by any suitable means. The reenforcing plate '8 will strengthen the roll, and can be used on the outside of the roll if desired, although it is preferably used underneath the roll so as construction as described to this point is substantially the same as disclosed insaid patent, but instead of having the bolt or fastening member s hift bodily toward the crown. of the roll as in said patent, only the intermediate or central portion of the bolt is shifted for clamping the handle member against and under the crown of the roll. This is accomplished, as shown'in Fig. 3. by using an arcuate or bent bolt 11', which is bowed or bent away from the'crown' of the roll, and said bolt is of suiiici-ently small diameter as to be flexible or resilient under the tensile'strain to which the bolt is subjected when it is tightened for clamping the handle member to the blade. In other words, a bolt is used which is of sufiiciently small diameter so that it will spring and tend to straighten out when tightened under tensile strain, without distorting or damaging the blade.
The bolt 11, as shown in F ig. 3, has a removable cotter pin or key 12 engaging therethrough near one end to be disposed at one side of the roll, and a nut 13 or other tightening means is engaged on the other terminal of the bolt to be disposed at the opposite side of the roll. Said nut, when tightened, will apply a tensile strain to the bolt, which will straighten ontthe bolt more or less, and the handle member extending across the intermediate portion of the bolt will be shifted by the bolt toward the crown of the roll for clamping the handle and blade tightly together. As shown, washers 1 1- are disposed between the sides of the roll and the nut13 and key 12, and have converted sides bearing against the roll to permit of a slight tilting movement of said washers by the flexing movement of the bolt. By using the key or pin 12, instead of an ordinary head on the bolt, such pan or key can be drivenyout or removed, when the nut .13 is: loosened, in
":order that the bolt or red 11 can be driven out through the apertures 9 toward the right as seen in Fig. 3, thereby avoiding the poss1ble injury to the threads of the bolt where the nut 13 is disposed, which might occur it the bolt was driven out in the opposite direction by removing the nut 13. In this n'iannel', the tensile strain applied to the flexible or bendablebolt or fastening member will flex or bend same toward a straight line position, thereby shifting the intermediate portion of the bolt or member and handle member toward the crown of the roll, for tightly clamping the handle mem= ber between said holtor mem ber 11and the crown of the roll. This will clamp the handle member and crown of =tl16 l."Olll1( gether tightly throughout the length of thelr contacting surfaces, and the use of the single securing element will provide a thoroughly rigid and substantial connection to .with-- stand the various strains. 1 i
In order to reenforce and strengthen the handle where it is secured in the roll, an elongated reentorcing plate 17 is fitted in a longitl'idinal vertical slot 18, cut in the shank'5 and extending from its gtorw'ard or lowered end. to a point adjacent to or beyond. the rear end of the; roll 2. The upper edge of the plate 17 bears against the upperportion of the tubular member 4, and therivets 6 and 7 extend through saidplate to secure it in place. The lower edge portion of; the plate 17 is disposedloetween the'edgesof the member 4, and the lower edge of said plate has a notched seat or portion 10 to engage and seat on the'bolt or member 11, as seen in Fig. 2. This serves a double purpose, because the pressure from the bolt or p member 11 is transmitted directly to the plate 17 and thus distributed to the member 4t and shank 5 in an effective manner, and, furthermore, the notched seat or portion 10 engaging over the bolt 11 will prevent the longitudinal displacement of the handle and blade relatively to one another, so as to lock them together when the bolt is tightened.
A modification is shown in Fig. l, wherein the fastening or clamping member 11. is somewhat different than the resilient bolt 11 as shown in Fig. 3. The member 11 is curved or bowed away from the crown of the roll; the same as the bolt 11. and although flexible, is not resilient. The member 11 is composed of the terminal. portions 20 and21 connected by links 23 pivoted to one another and to the portions 20 and 21, so that the sections or portions of the mem ber can swing relatively .to one another, and I the links 23 provide a short chain inv the member 11 to extend under the handle. hen the nut 13'is tightened. the member 11 will tend to straightenout, the same as the member or bolt 11, for, clamping the on the section or portion 25, and the section 2% has the slot 27 to receive the pin or key 12. This bolt or member 11" is bent or bowed away from the crown of the roll, and the pivot 26 permits the sections 24 and 25 to move toward a straight line position when the nut 13 is tightened. By using the pivot or hinge 26, the bolt 11 can be of larger diameter, and need not be resilient.
The convexed or tapered sides of the washers and heads on the bolts or securing mem= bers are seatable in the apertures in the sides of the rolls, whereby to permit of the tilting or swinging movements of said parts, without the terminals of the bolts or securing members shifting vout of position toward or away from the crowns of the rolls.
Having thus described the invention, what is claimed as new is 1. A tool including a blade having a roll, a handle member to fit within said roll, and flexible securing means extending across the roll and arranged to have a straightening out movement toward the crown of the roll when tightened, for clamping the handle member within the roll.
2. A tool including a blade having a roll, a handle member to fit within the roll, and securing means extending through the sides of the roll and bent or bowed away from the crown of the roll to have a straightening out movement when tightened, for clamping the handle member in the roll.
3. A tool comprising a blade having a roll for receiving a handle member, and flexible securing means extending across the roll and having a straightening out action when tightened for clamping the handle member in the roll.
4. A tool comprising a blade havingaroll for receiving a handle member and flexible securing means extending through the sides of the roll and bowed or bent away from the crown of the roll to have a straightening out movement when tightened, for clamping the handle member in the roll.
5. A tool comprising a blade having a portion for receiving a handle member, and a curved or bent securing member extending through said portion and adapted to be, tightened to have a straightening-out action for clamping the handle member to the blade.
6. A tool comprising a blade having a roll for receiving a handle member, and a securing member extending through the sides of the roll and curved or bent away from the crown of the roll and having means for ap plying tensile strain tosaid member to give it a straightening out action for clamping the handle member in the roll.
7-. A tool comprising a blade having a roll,
a securing member extending through the sides of the roll, said member being flexible and bowed or bent away from the crown of the roll, and means on said member for bringing it under tension and giving said member a straightening-out action for clamping the handle member in the roll.
8. A tool including a blade having a roll,
a handle member fitted within the roll, a
plate secured within said handle member, and securing means extending through the sides of the roll and having a straighteningout action when tightened to clamp the ban dle member in the roll, said plate having a portion to engage said securing means.
9. A tool including a blade having a roll, 7 a handle member to fit in said roll, a plate secured in said handle member, a flexible securing member extending through the sides of the roll and having means for tightening it, said member being bent or bowed I away from the crown of the roll to have a straightening-out action when tightened for clamping the handle member in the roll, said plate having a notched portion to engage over said securing member.
In testimony whereof I hereunto aflix my signature.
