DETACHABLE FERRULE.

Specification of Letters Patent.

Patented May 7, 1918.

Application filed December 4, 1916. Serial No. 134,986.

1 "0 (1.57 whom it may concern:

Be it. known that we, HEINRICH W. REIMER, of the village of Steinbach, and JOHN L. PENNER, of the city of Winnipeg, in the Province of Manitoba, Canada, have jointly invented certain new and useful Improvements in Detachable Ferrules, ofwhich the following is the specification.

The invention'relates to improvements in detachable ferrules and the object of the invention is to providefa detachable connection for fastening tools to their handles, Su h connection being constructed so that it is not'only strong and serviceable but positive when set and arranged so that it can be easily released.

sertible within one of the sleeve sockets, the" parts being arranged and constructed as hereinafter more particularly descrlbed and later pointed out in the appended claims,

reference being had to the accompanying drawing in which Figure 1 represents a perspective view of the tool having our invention applied thereon.

Fig. i 2 represents an enlarged detailed perspective view of the sleeve detached from i the tool and the collars on the sleeve and drawn back from the ends thereof.

Fig. 3 represents a longitudinal sectional view through the sleeve, the section passing centrally through the catches of the collars.

Fig. 1 represents a perspective view of one of the collars. I

Fig. 5 represents a perspectlve v1ew of the plug like head of the tool shank.

Fig. 6 represents a longitud nal sectional view through aportion of the large end of the sleeve showingv the catch thereof.

In the drawing like characters of refer ence indicate corresponding parts in the several figures.

In the present instance we have shown our ferrule as securing a hay fork of the ordinary type to a handle but whilesuch a tool has been shown it is to be understood that our invention is not restricted in any way to forks alone as it can be utilized to equal advantage in a great variety of other tools as will readily be appreciated.

1 representsa tool, in the present instance a fork, provided with a centrally located extending shank 2 which terminates in a conical plug like fastening head 3.

1 represents a handle of the usual form which has the forward end 4: thereof tapered in the ordinary way. The tool is detachably connected to the handle by the appliance now described which embodies as its principal parts, a sleeve 5 and a pair of oppositely tapered jam collars 6 and 7.

The sleeve 5 has one end thereof formed into an outwardly flaring or tapering socket 8 which is adapted to receive the tapering end of the handle and is provided with a side slit 9 throughout its length and the other end formed into a somewhat shorter outwardly flaring or tapering socket 10 which is also supplied with a side slit 11, the latter socket being adapted to receive the plug like head 3.

Between the sockets the body of the sleeve is strengthened by giving it increased thickness.

On the socket 8 we mount the tapering tional contact, the effective holding of the head and handle end in the sockets.

It will be readily seen that if these parts be properly designed an intense pressure can be brought on the sockets by striking the collars outwardly endwise such as by a hammer. This will produce a great jamming action of the sockets on the head and the tapering end of the handle. i

As the head is metal and the socket re-, ceiving the head is also metal, werely entirely on the frictional resistancebetween the engaging metal parts to hold the tool in the socket.

In connection with the handle however, where there is only the friction of the metal on the wood, we have considered it advisable as an additional precaution to provide the larger socket with a catch 12 which catch sis is formed by cutting the metal of the socket lengthwise adjacent the slit to provide a tongue 12 fitted at the free end With an inturned prong 12*. t

hen the handle is to be inserted Within the socket, the tongue is pulled out to initially clear the prong from the handle and vafterward and prior to tightening up the sleeve 6 the prong is struck into the Wood of the, handle taking a position such as shown inFig. 6. (n p u 7 With such an arrangement it Will be seen that it is practically impossible for the handle to draiv out of the socket vvhen the tool ijs in use and after the sleeve 6 has been tightened up a I I 1 In order to prevent ,eitherone or other of the collars from orking loose once they have been set We havesuppliedeach of them \vith a springpat ch indicated at l3 and 14 fofmed by slittingthe sleeves with parallel cuts andthen inturnin'g as ilndieated fat 15 the free ends of the slit pie'cesto provide catches which are adapted toliiiitially ride onthesu riface o'fthesockets when the coli s ar b'ei g' tig 1 p and t na ly take their. position in indentures or depressiops ie and 17 formed on the outer surfaces oft'hesoek'ets. 1 gh We have sho vvnsever'alcatches we, Wish it to be understood thatthe details e f/these are not essentialand furtherpthat they io'uldloe entirely dispensedwith if desired as We believe the ammed C Oller's will efiectively prevent theescape of either the handle or the head from the sockets when the 601 is in use.

Obviously when one Wishes to remove either ,theftool pihandl e he has simply to knock the collars to release'thefsockets whic i xvill, open owiiigto the slits in the sides thereof. J I e a V 'An imp'ortant fie'atiir'e in 'conneetionwith tliis ia 'jpliance is that henonce the tool is fastened it is properly eenter'ed. in respect to the'handle Such is not so injthe ordinary case Where a pron'g like shank isjdriven into the end of the handle. Inthis "instance it vvill loe readily seen that iiiilesstlie prong is truly centered on the longitudinal axis of the handle thetool Will not hav'e'a'trueposition. k W 13 p Whatiye claim afifour invention is; H
