HANDLEi-SECURING MECHANISH.

Application led February 9, 1920. Serial No. 357,830,

To all whom it my concem':

Be it known that I, PHILIP A. Grunn, a citizen ofthe United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Handle-Securing Mechanism, o f which the following is a specification.

My invention relates to improvements 'in handle securing mechanism and has for its object the provision of' means for. retaining a pivoted handle member in various positions of adjustment, which equally lend themselves to the release and readjustment of such handle member; v

The securing means comprise Va resilient detent for holding the handle in a prede-v termined position and aociated mechanism permitting the retention of the handle member inr a plurality of working positions, as desired.

` My improvements primarily arey designed for use with suction cleaning appliances and I will' describe the same in connection with apparatus of this character, for the purpose of setting forth the advantages and utility of the invention. 4

The embodiment of my improvements here set' forth comprises a portable electric suction cleaner equipped with a handle member rearwardl pivoted upon its'l casing by means of a iierked casting. One of the forked arms is associated with 'a sector slotted to receive a transverse securin bolt carrying a clampin thumb nut. A owed spring member is a apted to engage the bolt head in one position and resiliently hold the fork and attached handle member in a substantially upright position. The sector preferably is integral with the bowed spring and is partially secured in place upon the casing ofthe suction cleaner b means of the transverse pivotal bolt. urther details may be gathered by referring to the accompanying drawings, wherein:

Fig. 1 is a perspective view partially broken away rearwardly, showin a. portable suction cleaner equipped wit my improvements.

Fig. 2 is a `plan view of the blank as stamped out, from which the sector is formed.-

y Fig. 3 is a top view of the same after ity has been folded upon line A1- f, Fig. 4 is an enlarged fragmentary View in which the details of my improvements are shown; the thumb nut being used to retain the1 handle member in an angular position, an f y Fig. 5 is a-top 4view of the securing means in -which the spring is employed to retain the handle member essentially in upright position; .one of the forked arms being shown in section on line B-B, Fig. 4.

Throughout the several gures of the drawings I have employed the same character of reference to indicate similar parts.

Referring to Fig. 1, the general characteristics of a portable electric suction cleaner are shown, upon the casing A of which a handle member Ais rearwardly mounted. The handle member comprises the handle B shown lbroken away and its attachin .fork C, which is pivoted to the casing by t e transverse bolt One arm of saidy fork is equipped with a securing bolt E and the thumb nut E;

. the rounded head E of said bolt protruding beyond the slotted' sector F, which latter is seated Within the machined groove G, and rigidly secured therein by the pivotal bolt D. For the purpose of securing the sector directly to the casing to prevent the sector falling out of thev rooveG upon removal of the handle B and bolt D for any reason, a screw G is provided which extends through the sector F into the casing.

LThe sector F preferabl is formed integrally from the blank of Fig. 2,V by folding along the line A-A. This sector has a concentric slot F to accommodate the body of the securing bolt E and a bowed s ring memberF for en ging the head of said bolt when the gndle member is raised to its upright position slightly beyond the vertical, as indicated in Fig. 5.

During the use of the suction cleaner, the handle member is adjusted to any desired angular position with respect to the casing, such as will suit the usen By tightening the thumb nut E', this angular position of said handle member will be retained indefinitely, since it is ri 'dly clamped tothe sector F and thereby he d in operative position with the casing, as indicated in Figs. 1 and' 4. However, the handle member vmay be released merely b "loos ening the thumb nut, whenever it is esired to cha its angular position-or put away the suction oler.

Thus, Whenever the apparatus is to be stored during non-use, or when it is left standing in the room, it is desirable to elevate the handle member out of the way into substantially vertical position, wherein it Will be held merely by engaging the bolt head E with its coacting spring 1", as indicated in Fig. However, the handle may readily1 and instantly7 be released from this position merely by depressing it to the desired angle for operating the suction cleaner. Of course, the fork may be left entirely unsecured by the bolt E when desired, so that it- Will be freely movable about its pivotbolt D.

Having non' described the features of my invention and the preferred use and advantages thereby obtained` I claim as new and desire to secure by Letters Patent, the following:

l. The combination with a handle member, of a casing. an arcuate stop device secured to said casing, pivotal means for securing said stop device, clamping means for retaining the handle member in any desired position upon said arcuate stop device, and spring means adapted to directly coaet with the before mentioned clamping means Whereby said handle member may be temporarily and resiliently held in a given position.

2. The combination with a pivoted handle member, of a casing having a receiving groove7 an arcuate stop device seated Within said groove. a pivot mountingA said handle member and rigidly centering and `securing the stop device, clamping means for retaining the handle in adjusted position upon the arc as desired, a thumb nut controlling the same, and resilient means forming a part of said stop device and adapted to cooperate with said clamping means whereby the handle member may be resiliently retained in a different position, substantially as set forth 3. The combination with a pivoted handle member, of a fixedly mounted integral stopdevice associated therewith and comprising an arcuate portion and a laterally extending spring part adapted temporarily to engage and hold the pivote-d handle member in a given position, substantially as set forth.

el. The combination with a pivoted fork for a handle or the like, of an associated stop-'device rigidly mounted with respect thereto. means for clamping` the fork in adjusted position thereon, and resilientl means for temporarily holding said fork in a given position, substantially as set forth.

An integral stopmember formed from a single punching, comprising a body having an arcuate slot near one end and a spring portion extending freely from the opposite end of the body in position to be bent in overlying relation with respect to said slot, substantially as set forth.

G. The combination with a frame inember, of a pivoted handle therefor, an integral stop-member comprising a body having an arcuate slot and a spring detent portion overlying said slot, means for seeurinO- said stop-member to the Casing, an engaging detent upon the handle traveling in the arcuate slot in position to be held 2by the spring detent and means for rigidly clamping the pivoted handle in various positions of ad `iustment upon the stop-member, substantially as set forth.

T. The combination witha easing, of a pivoted handle therefor, an arcuate stopn'iember, secured within a groove in said casing, a pivot mounting the handle and rigidly centering the stop-member upon the easing, and clamping means associated with the pivoted handle, adapted to secure it in various positions of adjustment with respect to the stop-member, substantially as set forth. In testimony whereof I do now affix my signature.

PHILIP A. GEIER.
