HAND-TRUCK.

Specification of Letters Patent. "Patented J a 11, 1921 Application filed January 21, 1920. Serial No. 353,019.

To aZZ w 720m it may concern: I

Be it known that I, ELBERT L. HYDE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hand-Trucks, of which the following is a specification.

This invention relates to hand trucks, and is an improvement upon the hand truck shown, described and claimed in a priorapplicationfiled December 26,1919, by William Dunham, for hand trucks.

Said prior Dunham a plication illustrates a truck adapted particu arly for use in handling barrels, drums or like articles and so arranged thatthe truck can be upended into nestedrelation with a. drum standing on end and then tilted with the drum, whereupon certain toes or engaging members are moved in beneath the lower end of the drum to support it on its seat thereon. v

The object of the present invention is to improve the operating mechanism for said 1 supporting or engaging toes or members to enable them to be more easily operated and particularly towcause them to 'be actuatled either simultaneously with'or as the result, of the tilting movement of thetruck, to therebydo away with the necessity ofhandmanipulation of said Jmembersand leave the I operators hands free for taking care of the.

truck and load.

Further objects of the invention are in part obvious andvinpart will appear more in detail hereinafter.

The-invention comprises the construction parts-hereinafter deand arrangement of scribed and claimed.

In thedrawings, which represent one suitable embodiment of the invention, Figurel is a side elevation, showing the truck upended in nested relation with a drum; Fig. 2 is a rear viewof the truck; Fig. 3 is a sectional plan view on the-line 3-33, Fig. 1; Fig. 4 is a detail side elevation, illustrating a modification; Fig. 5 is a side elevation,

on a larger scale, illustrating theoperating mechanism at the lower end of the left hand side frame member in Fig.1, part .of a cover plate being omitted for clearness of illustration; Fi 6 is a front view, or a view from the left in Fig. 5, parts being broken away and in section; Fig. 7 is a sectional plan view on the line 7 -'-7 Fig. 5 ;=andiFig. 8 is a-view corresponding to Fig. 5 and showing the truck in tilted position. I

The truck shown in the drawings comprises. a suitable frame of the same general form illustrated in said prior Dunham a plication. Said frame includes two vparal el side members 1 formed of channel sections and each provided at one'end with an operating handle member 2.. The. side members are connected by suitable cross braces 3,

three of which areshown, and each of which comprlsesa curved inneror front member 4 and a rear substantially straight member 5, said members being suitably connected to the side frame partsand to each'other if necessary by rivets, boltsor the like. 'The front members 4: are curved on the arc of a circle, the diameter of which is thediameter or approximately so, of the drum,'barrel or other article 6 to be manipulatedby the truckand the several inner members 4 together form aconcave seat for said article- The curvature of members 4 is suchthat the bottom of said seat, indicated atv 7, Fig. 3,

isfin a transverse plane parallel with and passing through the rear edges 8 of the truck frame side members, or at least said mem bers are socurvedthatthe bottom of said seat is behind or in rear of the heel of the truck, as will later appear. The truck frame.

is ,also provided withsuitable supports 9 for the axle 10 on which are located the wheels. 11. Thesewheels are of such size and axle 10 is solocated that when the truck is upended,.as in Fig. 1, the wheels lie an ap,

preciable distance above thelevel of the floor or other support. v I n I Toward 'ts handle end the truck frame is provided,'near the bottom of the concave drum seat therein, with suitable means'for engagingthe upper endof the drum or other article to be handled- This engaging means may be of any well known or suitable description, such as a chain fastened to the 7 frame and adapted to surround the upper end of the drum or may be of the form shown in said prior Dunham application, towit, a latch 12 providedwith ahandle 13 and pivoted at 14 to a cross brace, said latch being provided with a hook portion 15 adapted when the latch is moved down to the position shown in the drawings to embrace a part of the cross brace andalso the drum chime16. Fig.4 shows another arrangement in which the holding means comprises a hook 17 at one end of a chain or cable 18 fastened to a cross brace 19 connecting the usual legs 20 which support the truck when in horizontal position on the floor.

Each of the side members of the truck frame is provided at its wheel end with "a movable drum engaging member so arranged as to be capable of being moved into engaging or supporting position beneath the lower end of a drum when the latter is tilted, and the truck frame is also provided with suitable actuating means for said members preferably so arranged as to cause actuation there either simultaneously with or as the result of the tilting movement of the truck. The mechanisms at the wheel ends of the two side frame members are identical except that one is aright and'the other is a left so thatdescription of one will sufiice for both.

Each engaging member comprises an arm or lever 21 pivoted at 22 and provided with a toe portion 23 movable through an opening 24 in the front portion of the frame member. The two members 21 maybe at:- tuated simultaneously with or during tilt ing motion of the truck by pressure applied by the foot to a bail or U-shaped member 25 coupling or connecting said levers 21 and which bail extends rearwardly from the frame. However, to avoidany necessity for attention by the operator each side frame member is provided with means actuated by tilting movement of the truck and operatively connected to said levers 21. The means shown comprises a member 26 having a shoe portion 27 resting on the floor, said member being pivoted at 28 and being provided with an upwardly extending arm 29; Eachlever 21 provided with a pair,

of rearwardly extending ears 30 having curved slots 31 to receive the ends of a pin 32 in the arm 29; Member 26 also has a rearwardly extending portion which closes the opening at the rear of the side frame member so as to prevent the entrance of foreign matter thereinto. -The mechanism is in'closed and protected by a cover plate 34.

Fig. 5 shows the normal position of the parts. The lever 21 is retracted and only a small portion of the toe 23 extends through the opening 24:, this portion being beveled or inclined'laterally, as at 23, so that it will substantially form a continuation of the concave drum seat and nest closely with the drum when the truck is applied thereto, as in Fig. l. The axes or pivots 28 of the members 26 are located in front of the bottom of the concave seat, and more specifically are shown as being located about midway between the front and rear edges of the side frame members. These pivots-are the pivots upon which the truck effect is to. tilt the truck relatively to the members 26, which rest solidly and immovably upon the floor, until the parts reach the dotted line position, Fig.1. During this first motion there is no movement of members 21, as the pins 32 ride idly along the slots 31. During the same motion, however, the barrel or drum, which. rests on the floor and turns about a transverse axis at the bottom of the concave seat in effect moves upwardly along the truck, approaching the position shown in dotted lines, Fig. 8. Therefore the important effect is to move the toes 23 downwardly to a position below the bottom of the drum. By this time the pins 32 have reached the front ends'of slots 31,- so that additional tilting movement of the truck causes the arms 29 to advance the levers 21 and move them to the position shown in Fig. 8, in which position the toes 23 have been introduced or projected into engaging or holding position be neath the lower end of the'drum. Fig. 8 shows the final {position of the parts just before the wheels 11 touch the floor. Fur-- ther tilting movement of the truck engages the wheels with the floor and lifts the side frame members 'with the drum supported thereon from the floor.

The drum is deposited in upended position in' its new location by reverse operations. As the drumis tilted toward Vertical position the members 26 engage the floor and withdraw members 23 from beneath the drum and finally reach the position shown in Fig. 5. In the operation oftilting the truck toward the vertical the drum strikes the floor first and is' pushedupwardly on the truck a slight amount to free it from the holding members 23 so that the-latteiare readily "withdrawn.

In the position shown in Fig. 8 pressure applied to the members 21 will not push them backwardly to normalposition, as the pins 32 will wedge in the ends of the slots 31, thearrangement in this position being in effect a toggle. Therefore, when the holding members are extended they are in effect locked and can only be retracted by operation of members 26. In a similar manner the parts are locked in retracted position, as shown in Fig. 5', the locking effect being due in both instances to the presence of the slots 31.

Members 26 with their arms29 maybe Wholly omitted and-the members 21 open ated by the bail 25, but if the members 26 are utilized the bail25 may be resorted to for movement of the truck for members.

producing extra pressure to move members 21. Bail 25 has the more important function of coupling together the holding members 23 on the two sides of the truck frame so that both of them are compelled to operate in unison at all times.

What I claim is:

1. A hand truck provided with a frame and wheels thereon, said frame being formed to provide a seat for an article, and means on said frame actuated by tiltin movement of the truck and thereby movabic into said seat beneath an article tilted with the truck.

2. A hand truck, comprising a frame having parallel side members and provided with wheels, said side frame members near their wheel ends being provided with article engaging means, and means actuated by tilting operating said 3. A hand truck, comprising a frame provided with wheels and a seat for an article, means near the wheel end of said frame for entering said seat and engaging the lower end portion of an article therein, and means whereby movement of the truck frame actuates said article engaging means.

4. A hand truck, comprising a frame pro vided with wheels near one end, article engaging means near each end of the truck, and means actuated by movement of the truck for operating the means near the wheel end.

5. A hand truck, comprising a frame pro vided with an article receiving seat, means near one end of said truck for entering said seat to engage an article therein, and operating means therefor engaging the floor when the truck is upended thereon.

6. A hand truck, comprising a frame having side members, wheels thereon, oscillating article engaging members mounted one on each side frame member, and a bar coupling said oscillating members to move together.

7. A hand truck, comprising a frame having side members, wheels thereon, oscillating article engaging members mounted one on each side frame member, a bar coupling said oscillating members to move together, and floor engaging means adapted to actuate said swinging members.

In testimony whereof I aflix my signature.
