SELF-WEIGHING SCOOP.

Specification of Letters Patent.

Patented March 23, 1.909.

Application filed December 1908. 'Serial No. 4=65,98ll.

To all whom it' 'may concer/a.'

Be it 1Known that l, Altri-ion lil. ARNOLD, a citizen of the United States, residing at Central, in the county of Pickens and State of South Carolina, have invented new and useful improvements in Self-'llfeighing Scoops, of which the following is a specification.

The invention relates to an improvement in self-weighing scoops, being designed more particularly to present a scoop of this type in which the material may be readily lifted and its weight accurately determined in a convenient and expeditious manner.

rhe main object of the present invention is the provision of a self-iiieighing scoop in which the parts are so arranged and constructed as to provide for their convenient assemblage or disconnection when desired.

The invention will be described in the following specification, reference being had particularly to the accompanying drawings, in which lliigure 1 is a view in elevation showing the improved weighing scoop. Fig. 2 is a perspective of the spring member. Fig. 3 is a perspective of one section of the holder. Fig. 4 is a perspective of the other section of the holder. VFig. is a perspective of the standard.

Referring particularly' to the accompanying drawings, my improved scoop comprises a bowl 1, which, so far as the purposes of the present invention are concerned, may he of any desired size or form. The handle or upper end of the howl is formed to receive a scale standard 2, preferably squared in cross section and formed near one end with a bead projection 3 to accurately position the standard with relation to the bowl and at the same time form an ornamental connection at this point. N ear the opposite or upper end one surface ol' the standard is cutaway, as at Li, to receive an approximately U-shaped metal strip 5, one arm of which projects in parallel relation to the proximate surface ol the standard and is spaced therefrom to provide a pointer 6, for a purpose which will hereinafter appear.

The holder for the reception of the standard is made up of two semicylindrical sections 7 and 8 designed to he secured with their plane edges in contact to provide when the sections are assembled a cylindrical memher. The contacting face of each section is longitudinally and centrally channeled to provide an approximatelyT rectangular recess l l i l i l inserting said standard 9 extending throughout the length of the section. T he recesses are so formed that when the sections are assembled the cylindrical holder provided is longitudinally and centrally formed with a rectangular opening of a site to slidably receive the standard 2. The upper end of each section is reduced on trie contact face in a direction transverse thc length of the sections, as at 10, so that when the sections are assembled a rectangular channel is formed in the upper end of the holderI extending transverse the longitudinal channel. The section 7 on the contacting faceis cut away at one side of the longitudinal channel i) to provide a longitudinally extending recess 11, .vhich opens from the channel 9 outwardly through the roundedl surface of the section and extends from a point a slight distance above the lower end of the section to a point below the lower' wall of the channel 10. The rounded surface of the section 8 is cutaway to form a scale receiving recess 12, which recess is approximately of the length of the recess 11 and opens through that edge of the section 8 which is coincident with the recess 11 of the section 7. ln the recess 12 is secured a scale 13 preferably `formed near each end with an elongated slot 14 through which screws 15 are arranged to tale into the material of the section 8, the slots 11i and the relativo lengths of the scale 15 and recess 12 being dcsigncd to permit longitudinal adjustment of the scale in order to accurately compensate for the weight of the scoop.

The holder and standard are assembled hy in the squared opening formed lon gitudinally of the holder with the laterally extended portion of the strip 5 resting in the recess 11 of the section 7 and the pointer 6 overlying the scale 13. A cross har 16 is adapted to be inserted in the recesses 1.() of the assembled sections, from which cross har depends a coil spring 17 adapted to rest in the cored out channel of the holder, the lower terminal of the spring being formed to provide a hook 18 to removahly engage a perforated ear 1.9 formed at the upper end of the standard 2. lThe longitudinai movement of the standard relative to the holder under the influence of the weight of the material in the scoop is thus resisted by the spring 17, and the pointer moves over the scale 13 to register the extent o'i the movement and thereby the weight of the material in the scoop. The holder and connected parts are supported within a cylindrical casing a0 closed at top and open at bottom, the casing being secured to the holder by screws 21 taking into openings formed in the respective sections. rlhe cas* ing is formed with an elongated opening 23 through which the pointer (5 and scale 13 are visible to enable the user to readily determine the weight of the material in the scoop.

rlhe bowl l is provided with a cover 24 of appropriate shape, which, near its rear end, is formed with ears 25 designed to be pivotally connected to the bowl, a handle 26 projecting from the cover beyond the ears for convenient operation of the cover when de sired. in advance of the ears 25 the cover is designed to lit snugly in contact with the proximate edge of the bowl, and such edge of the cover is formed to provide a bead 27 in which is secured a length of spring material 28, which beyond the ends of the bead and adjacent the ears 25 is coiled, as at 29, and terminally secured at 30 to the bowl. lThe spring acts to normally hold the cover in closed position relative to the bowl, thus forming a closed scoop which will readily hold the material during the weighing operation.

The use of the improved weighing scoop is readily apparent Jfrom the above description taken in connection with the drawings, it being particularly noted that by the removal oi the casing 20 the operative parts oi" the scoop are readily separable for repair or other adjustment.

Having thus described the invention what is claimed as new, is

l. A scoop including a bowl, a cover hingedly connected thereto and formed throughout its operative edge with a bead, and a spring held within the bead and terminallyconnected to the bowl.

2. A scoop including a bowl, a cover hiiigedly connected thereto and formed throughout its operative edge with a bead, and a spring held within the bead and terminally connected to the bowl, said spring intermediate its connection to the bowl and f the bead being -formed to provide a coil.

A weighing scoop including a scoop proper, a standard projecting therefrom, a

pointer carried by the standard, a holderl l standard receiving opencomprising semicylindrical sections each formed with a longitudinally extending channel to receive the standard when the sections are assembled, a scale connected to one of the sections to cooperate with the pointer, and a spring member removably connected to the sections and to the standard.

4. A weighing scoop including a scoop proper, a standard projecting therefrom, a pointer cariied by the standard, a holder comprising semicylindrical sections each formed with a longitudinally extending chan* nel to receive the standard when the sections are assembled, a scale adjustably connected to one ol' the sections to cooperate with the pointer, and a spring member removably connected to the sections and to the sntaiidard.

5. A weighing scoop including a scoop proper, a standard projecting therefrom, a pointer carried by thc standard, a holder comprising semicylindrical sections each formed with a longitudinally extending channel to receive the standard when the sections are assembled, a scale connected to one oi the sections to cooperate with the pointer, a spring member removably connected to the sections and to the standard, and a casing encircling the holder sections and secured thereto.

6. A weighing scoop including a scoop proper, a standard conne `fted thereto, a holder comprising sections adapted to lac connected to form a cylindrical body, said sections being each formed with a longitudinally arranged channel designed to register when the sections are assembled to torni a g, the contacting edges oi the sections adjacent their upper ends being formed with transverse channels. a cross bar iitting within the registering channels of the assembled sections, and a spring depending irom said cross bar and connected to the standard.

In testimony whereof affix my signature in presence of two witnesses.

ARTHUR lil. ARNOLD.
