, AND GEORGE LEDERMAN, OF CLEVELAND,

OHIO; SAID LEDEEMAN ASSIGNOR TO SAID ANTHONY.

TRUNK-DOLLY.

To all whom it may concern.

Be it known that we, (1) Masons 0. AN TIXONY, (2) GEORGE LEDERMAN, citizens (1) of the United States, (2) of Russia, residing at (1) New York. in the county of New York and State of New York, and (2) at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Trunk-Dollies, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to attachments for trunks and more particularly to such attachments as are commonly known as trunk dollies.

Heretofore hotels and other places for en tertaining travelers, as well as stores where trunks are displayed, have had their floors considerably marred by the sliding of trunks thereover, and this is particularly noticeable in the case of wardrobe trunks which are usually stood on end, in one place, and opened and closed a number of times over a fixed path on the floor.

Some of the objects of the invention, therefore, are to provide an attachment of this character which shall be quickly and easily fitted to trunks of various sizes and styles, and which shall permit. moving a trunk so fitted with a minimum effort and without marring the floor; to provide an attachment of this character which shall be particularly adapted to wardrobe trunks, and which shall permit opening and closing of such trunks with a minimum effort and without damage to the floor even though swung thereover, through a fixed path a number of times; to provide an attachment of this character which shall be simple in construction and inexpensive to manufacture; while further objects and advantages will appear as the description proceeds.

In the accompanying drawings wherein we have shown certain illustrative embodiments of our invention, but without intent to limit ourselves thereto, Figure 1 is a top plan view of the preferred form of our invention; Fig. 2 is a side elevation thereof; Figs. 3 and 4 are enlarged detail sectional views taken on the lines 3-3 and H, respectively, of Fig. 1; Fig. 5 is a detail per- Specification of Letters Patent.

spective view of one of the parts and Fig. 6 is a perspective view of a modified form of our device.

The preferred form of our invention, as illustrated in Figs. 15 comprises a rectangular frame indicated generally at 1 which is composed of the longitudinally disposed members 2 and 3, each of which has an upturned end forming abutments f and 5, respectively, and the transverse members 6 and 7, which are fastened, one at each end, to the members 2 and 3, by any suitable means the rivets 8, said rivets serving also in the present instance to fasten a caster 9 to the under side of each corner of the frame 1. The transverse member 6 is provided with a guide bracket 10 on the un der side thereof to slidably receive an arm 11 which is formed with a'series of apertures 12 extending inwardly from one end thereof, and at the other end said arm extends upwardly to form an abutment 13. A slider 1 1 having guide arms 15, 15 and a lug 16, is movable along the arm 11 to engage the lug 16 in an aperture 12 by means of a pull rod 18 fastened to a clown-turned portion 19 of said slider. The forward end of rod 18 is supported and guided by a bracket 20 fastened to the guide bracket 10. A compression spring 21 is interposed between the bracket 20 and the down-turned portion 19 of the slider and tends normally to force the arm 11 inwardly. The slider 14; is preferably so formed as to permit a slight rocking motion between the guide arms l5, l5 and the arm 11 so that the spring 21 tends normally to hold the lug 16 into engagement with one of the apertures 12, but by pulling forwardly on the rod 18 the rear end of the slider is drawn downwardlv ments 4, 5 and 13. The arm 11 is now pushed inwardly to engage the side of the trunk and the rod 18 pulled outwardly to wardly by the pressure of the spring, to engage the lug 16 into one of the apertures 12 at which time the force of the spring will be transmitted to the arm 11 to grip the trunk between the abutments. In practice two dollies are usually applied to the bottom of each trunk, one at each end thereof and in the case of wardrobe trunks, one is applied to each opening half of the end on which the trunk is stood.

Fig. 6 is amodification of our device an is of the self adjusting type. In this form, a longitudinal channel beam 30 has one end thereof upturned to form an abutment 31. A pair of parallel disposed supporting members 32 and 33, each have an opposite end thereof upturned to form suitable clamping abutment-s 34 and 35, respectively. The members30, 32. and 33 are connected together by a series of pivoted links 36. A pair of tension members 37-37 which connect the member 32 with each of the mem bers '30 and 33 tends'to draw said members together laterally. The frame is supported on suitable casters 38 mounted similarly to those previously described in connection abutments 31, 34: and 35.

Vfhile we have described our device as particularly adapted to trunks, it will be understood that they are applicable to boxes and similar objects, without departing from the spirit of our invention, except as set forth in the appended claims.

Having thus described our invention, what we claim is z- 1. A trunk dolly adapted to be secured to the bottom of a trunk andromprising a rectangular frame having a fiXed abutment projecting upwardly from one end thereof, a wheel pivotally supporting each corner of said frame, a movable abutment mounted at the opposite end of said frameand adapted to cooperate with said fixed abutment to clamp said frame to said trunk, and means for retaining said movable abutment in adjusted position.

2. A trunk dolly adapted to be secured to the bottom of a trunk and comprising a rectangular frame having a fixed abutment projecting upwardly from one end thereof, pivotally mounted wheels supporting said frame, a movable abutment positioned at the opposite end of said frame and adjustable toward and from said fixed abutment to clamp said frame to the trunk, and tension means arranged between said frame and movable abutment forretaining said abutment in contact with said trunk.

3. A trunk dolly adapted to be secured to the bottomof a trunk and comprising a rectangular frame having a pair of fixed abutments projecting upwardly from one end thereof, a caster pivotally mounted at each corner of said frame, a single movable abutment slidably mounted at the opposite end of said frame and adapted to cooperate with said fixed abutments to clamp said frame to the trunk, and tension means cou pled between saidframe and said movable abutment, said tension means being adapted to retain said movableabutment in contact with said trunk.

In testimony whereof, we hereunto affix our signatures.
