Description

Patented Sept. 19,

To all whom ii may concern Be a known that 1, WILLIAM immie,

a citizen'of the United States of America,

' residing at"Spriiigfield,, in the" county'of Hampden andcommonw'ealth of Massachu setts, have invented certain newflfland use- 1 ful Improvements'in Hand Trucks, of which 1 .the following a specification."

Thisin'vention relates to improvements in ous liinds of merchandise, as rolls ofpapenf burla caraets etc. since the ton ue or ro- I jecti'oninjur'e's or'tears'the ,lower edge of thefiro'll,.-eitherf 'whenloading it onto the truck, 'or during transportation. I, i

One of the objects, therefore, is to avoid the use of thisprojecting-tongue portion,

and to firmly secure the roll'of paper, or

other merchandise to the truck by means of a flexible band which encircles the roll and which is provided with means for tightening the band for firmly clamping and holding the roll against the truck while it is moved from place to place. The tightening means is so constructed that it automatically remains in locking. position, the construction involving the principle of the toggle joint.

Referring to the drawings:

Fig. l is a perspective view of the truck and the retaining means for holding the roll in place, and showing the roll before be- 40 mg mounted upon the truck.

*ig. 2 is a view similar to Fig. 1 showing the roll after being encircled by the band or strap, and before the clamping takes place.

Fig. 3 is an enlarged sectional view of Fig. 2, on the line 3-3, showing the position of the' handle and band before the clamping action.

Fig. 1 is a view similar to Fig. 3, showing the lever in its locking position.

Referring to the drawings in detail: 1 and 2 designate the usual side bars of the truck, and the wheels and axles are indicated at 3 and 4 respectively. The bars 1 and 2 are connected together by the usual pieces of bent strap iron 5. .Secured to the bars rection of the arrow 11.

WILLIAM F. Emma, or srnrivei i nnn,massacnnsnr'rsj l ,Y ANDTRUCKQ. l I i 1 and "EZ-andat 'the rear edgesthereof, are 1 l the angle iron pieces (Sand 7 and attached to these pieces by means of the the band .9 which is used for retainingthe in8is rollofpaper, indicated at 10, in place on the truck. The band is tightened or drawn 7 firmly-against the roll" by the following 1 mechanism!" A. lever 11, formed'with-parallel bars- 12 and 13, is pivoted to the angle iron bars 6* and"? fat the pointy 14. ,Pivotally mounted I between the bars 12 and 13 is'a latch or dog 15, and cooperating with this latch is the 1 pin 16 over whichpa's'ses the free end of= the hand 9 shown in Figs. 3 and 4. Figs; Qand 3 show the holding band after it has been passed "around the roll of. paperllO, and just before thelever 11 'is sw'u'ng in the di- 9 is placed as shown-in Figs. and 3 and with slight/pressure onthe roll" 10, the lever "is then moved into-the positionshown in Fig.4. This operationtightly "'draws'the band'- 9'firmly against-the 1 11., The lever "8o 11in its locking position passes-by-the line of stress indicated by the line 1616. The line ,17-17 indicates the line or positionof the bearing-or pivotal points 14: and'16 oi the lever 11 when in its looking or holding position. In other words, the line 17-1? is within the line 16'-16 and the lever 11 is therefore automatically looked as the line 17--17 swings over the line 16-'16". It is understood that the lines 1717 and '90 16-16 represent the diiferent positions of the lever 11. I

The band 9, it will be noticed, has a bearing on the side frame 1 and 9, thereby serving as an additional means to prevent the band from slipping back or losing its hold. The roll is therefore very tightly drawn against the cross braces 5 and against the'side bars 1 and2. When the band is in its clamping position the roll 10 cannot slip or sag downward, since it assumesthe somewhat inclined position, shown in Fig. 2. 11in other words it'acts as a bight on the rol It will be seen that I have provided a very eiiicient means for retaining a roll of paper or other merchandise on the usual hand truck and without the use of the usual tongue or projection at its lower edge. I

It will further be seen thatjI have pro- 110 vided a roll clamping or holding means that Aaer the bandy lease a roll of paper or other merchandise, on the usual wheel or caster truck.

The pin 16, it will be noticed, enters the recesses 6' and 7 in the bars 6 and '7 when thelever 11 is in its locking position.

What I claim is:

1. In a truck of the kind described, the combination with the upright side pieces of the same, of bars secured to said pieces and extending transversely of the uprights, a flexible band, having one end secured to said bars, lever means pivotally secured to said bars, a pin on the lever, a dog on the lever and spaced from the pin to receive the free or other end of the hand therebetween, whereby when the lever is .operated the band will be tightened, as described. v

2. A clamping device for retaining a roll or the like on the upright pieces of a truck of the kind described, said device comprising a flexible band having one end secured to one of the upright pieces, a lever pivoted near the other upright, a clamping device on the lever to receive the free or other end of the band, the location of the pivotal connection of the lever and clamping device beingsuch that the lever automatically assumes a toggle orlocking position when in its roll holding position.

3. Ina truck, a pair of side pieces, mem-c bers arranged across the side pieces, a

flexible band connected at one end to the members, a lever pivotally connected to the members, clamping means on the lever to receive the free or other end of the band, whereby when the band is tightened against a roll, or the like, said band will retain the roll in place on the truck by forming a bight against the same, as described. v

eL'In a truck of thetype described, the combination, of means for securing an article thereto, said means including a flexible band for gripping the article and combination, with the frame thereof of flexible means designed to be passed around the article and devices for placing tension" on the flexible means for retaining the article in place on the truck as described,

said devices including a lever which is pivotally connected to the frame and is automatically retained in place when tension is applied to the flexible means.
