DETACHABLE HANDLE FOR SAD-IRONS.

SPECIFICATION forming part of Letters Patent No. 680,143, dated August 6, 1901.

Application inea February 2e. 1901 To 1r/ZZ whom t may concern:

Be it known that I, PETER C. GREENAWALT, a citizen of the United States,residing atReading, in the county of Berks and State of Penn- Sylvania, have invented certain new and useful Improvements in Detachable-Handles for Sad-Irons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others ro skilled in the art to which it appertains to make and use the same.

This invention relates to sad-irons having detachable handles; and the objects of the invention are to provide constructions, combinations, and arrangements of means whereby a detachable handle can be coupled to and uncoupled from the iron proper in a very ready and perfect manner; also, to provide a novel construction, combination, and arzo rangementV with the iron proper and the handle-plate and handle proper of a springactuated latch whereby said handle can be automatically latched to the iron near both of its ends without manipulating the latchbutton, it simply being required to take hold of the detachable handle and place it upon the iron proper in a position transverseto the said iron and then give the handle a quarterturn, all as will be hereinafter described. 3o These objects are accomplished by the devices described in the following specification, and illustrated in the accompanying drawings, in which latter- Figure l represents a side elevation of the improved sad-iron, partly broken away to show the interior of the iron proper and parts which would be concealed otherwise. Fig. 2 represents a horizontal section of the improved iron looking upward. Fig. 3 repre- 4o sents a plan view of the iron with the handle removed. Fig. A represents an inverted plan view of the detachable handle. Fig. 5 is a -tersunk into the said plate B', as shown.

.l Serial No. 49,262. (No model.)

A represents an iron proper; B, a handle 5o proper; B', a metal plate connecting the base ends of the handle proper; b, a coupling-lug having lips b'; C, a spring-actuated latch; C',

a knob or button by which the latch is raised to uncouple the handle from the iron proper; 5 5 O2, a spring for actuating the latch, and o a stud for centering and guiding the handle and also serving as a pivot for the handle to turn upon.

The body A of the iron is provided with a 6o chamber a, and is provided with a removable cover or plate ct', which is held in place by screws a2 a2, as clearly shown in Figs. 1 and The plate a is provided with an elongated passage cts, which is enlarged centrally of its length, as at a4, as clearly shown in Fig.

3. By this construction the topplate or cover a', adjacent to the passage a3, forms shoulders or anges 0,5 for the engagement of the retaining-lips b of the coupling-lug b to pass 7o under after the lug has been inserted through the passage a3 and during the act of giving the handle a quarter-turn. The passage as, enlarged, as at'a4, allows of the introduction of the inverted-T- shaped coupling-lug while the handle is transverse to the iron, and the said flanges of the top plate serve for preventing the handle separating by an upward movement from the iron proper after the handle has been coupled in operative posi- 8o tion to the iron.

The handle B is preferably made of wood and in curved form and has its base ends connected to the metal horizontal plate B by means of screws E, having their heads coun- The plate B' is flat on its top and bottom and of oblong form and may have rounded edges and ends, the latter corresponding to the bottom ends of the handle proper. This plate is 9o bulged on both sides between said handle ends, and in its bulged part vertical, segmental, or other suitably-shaped passages d are provided, and between the passages d a longitudinal slot d is provided for a purpose hereinafter described, and on the under side of the plate B' is cast a downwardly-projectingv tubular lug b, having two horizontal lips the thickness of the removable cover or top of the iron proper, and thus when the lips of the inverted-T-shaped coupling are fully inserted into the chamber a, so as to bring said coupling-lips below this top plate, and the lug is turned by the handle so as to bring the same beneath the edgesof the top plate, the said edges will occupy the space between the lips and the handle-plate B and prevent the handle from separating from the iron when an upward pull is exerted upon the handle or theiron lifted by the handle. The passage through the coupling lu'g is flared downwardly.

The centering or guiding pivot or vstud o is slightly conical and is cast on the'i'ron proper, it rising from the bottom of the chamber a and extending up to near the top of the iron proper. This stud enters the central passage of the tubular lug when the handle stands transversely of the iron and remains vin said passage of the lug after the handle-is adj usted to its working position, and thus the-couplinglug of the handle-plate is vcentrally guided through the passage leading into the chamber a. adjusted, with the lug b between the inner edges of the top plate and lits lips below the the same, the stud c serves-as a pivot for it to v coupling-lug l), it ybeing bridged -or partly closed between its right and left portions vby said-coupling-lug. Invthis slot the-latch C is placed so that its upper edge comes flush withr the top of the plate B and its legs lc" pass entirely through the slot d and enter snugly into the reduced ends of the slot (L3-at each end of the plate a' of the iron proper.

The curved wooden portion B, forming the handle proper, is provided at vits base ends,'

on the inner surface, with'vertical slots ffor the reception of the extremities f of the spring-actuated latch, said slots f serving in` con-junction with the slot in the plate -as guides, while the shoulders Vat their 'upper' ends limit the upward movement of the latch, and thus while the latch is guided by the slot of the plate and the latching-legs, it `is kept from being lifted to a 'height which would bring the ends of the legs above the plate and allow the latch to move to one side or get out of connection with the handle, which sidewise movement would take place When the handle has been properly:

if theextremities of the latch were not inserted -into the slots f land the legs of the latch were lifted above the top of the plate. Of course the latch would be guided without the slots f, and therefore these slots are only specially useful for holding the latchin its connected relation-to the handle under all circumstances.

A flat spring C2 is interposed between the knob C and the latch C, the outer ends of the said spring resting in recesses yO5 and being secured between the plate B and the lower edges of the wooden handle and secured centrally of .its ends to the latch C by means of the knob C', so as to bear upon the top of the latch and hold the same normally down. By this construction the latch is not only rendered'automatic in its locking action, but ksaid action is rendered very-quick, positive, and certain. This is regarded as a very important feature of the invention.

When itis desired to attach thehandle tothe heated iron proper-,thelugb is placed `by the handle lengthwise of the passage leading into the vchamber d, the handle lowered, the lug forcedinto 'said passagaandduring this opera tion the latch is forced upby the legs coming in contact with the top of the iron proper. Now bygiving-a quarter-turn to the handle the lips -b of saidlug will be forced under the overhanging flanges formed by the top .plate ofthe iron', so that the handle will be held against separat-ion by ran upward pull upon it from the iron proper. At the instant that the handle is turned to the above-mentioned position the latch, by reason Vof the spring, immediately descends and its legs enter the reduced vends of the slot asvof the iron proper and effectual'ly prevent the handle from being turned back Auntil said legs are raised by the button or knob 'and are disengaged from the walls of s'aid slots;

To cast the lplate B Vwith the inverted-T- headed coupling on its `under side 'and also with the passages d inthe widened central part of the plate, the sand to form the passages is molded up through holes in the pattern.

yThe lifting-button-Cis attached to a pin secured to the latch central of its length, and thus can be 4conveniently Amanipulated and caused to draw both ofthe legs of the latch at the'same instant out of the slot asfand thereby unlatch the handle and allow it to be vturned at a right angle to the couplingpassage and to be uncoupled `from the iron proper.

yllavingnow described my inventiomwhat I claim is4 1. In a sad-iron, the combination ofa'body portion `provided with a central socket having overhanging flanges,a detachable handle havinga plate attached-to its lower ends,'the said plate vbeing constructed with a downwardly, transversely arranged and an inverted-T-headed coupling-lugand with a vertical, elongated opening for the passage of IOO esame a spring-actuated latch or bar' having a knob located about midway of its length for lifting the same so as to be readily grasped between the fingers without removing the hand from the handle of the iron, a flat spring for actuating the latch or bar extending the entire length of the same, and secured about midway of its length to the top of the latch by the lftingknob, the outer ends of the spring being secured between the lower ends of the handheld and the handle-plate, the construction and arrangement being such, that when the handle is properly placed on the body of the iron proper, at right angles thereto, the inverted-Theaded coupling-lug will enter the passage, and when the handle is turned parallel with the longitudinal axis gf the body of the iron proper the inverted- T head will pass beneath the overhanging flanges of the body portion proper and the springeactuated latch will automatically descend and prevent the handle from being turned, substantially as described.

2. In a sad-iron the combination of abody' portion provided with a central chain-ber, and

a removable cover forming overhanging iianges, said cover being provided with an elongated slot having an enlarged central portion, and a centering-pin arranged within the enlarged portion of said slot of the removable cover and projecting vertically from the interior of the iron proper, a detachable handle having a plate attached to its lower ends, said plate being conn ected with a downwardly extending transversely-arranged and inverted-Theaded coupling-lug, an automaticallyoperating engaging latch operating in a slot in the base of the handle and provided with a knob for lifting the same, and with engag ing lugs, and a flat spring resting upon the top of the latch and 'connected therewith between its ends by means of the lifting-knob, the outer ends of said spring being secured to the handle, substantially as described.

In testimony whereof I hereunto affix my signature in resence of two witnesses.
