' Application fi1ed'July28, 1914. Seria1 No. 8 53,778.

To all whomit may concern 7 Be i known thatzI, SAMUEL provement in Table Tr'ucks, of which the following isa specification.

Mypresent invention relates generally. to trucks for transporting articles from one.- place" to another andmore particularly'to a. v truck of considerable'lengthsuch as is used as a checking table to receive bolts androlls' of" cloth goods and" the'like by manufacturers' and wholesalers, my object being to provide a table truck of this nature which'is' constructed in sections shiftable' to horizonv tal and. vertical-3 'alineInent*with-' respect to one another, whereby when'infhorizontal'.

the goods thereon may be moved to an elevator and then moved from one floor to another of a building in order that removal of the goods from one table truck at. one floor and the replacing of such goods upon another truckat"v a different floor may he obviated;

In the accompanying of'the table truck' in'extendednormal position. Fig; 2i's a plan view thereof; Fig. 3

is a central vertical sectionillustrating the initial step 'of'movement of the table sections 7 toward vertically alined position." Fig. 4 is atransverse verticalsection on an 'enlarged: scale taken substantially on line H of Fig.2. Fig. 5 is a similar view taken substantially on line 55 of Fig. 1. Fig.

6 is a sectional plan view showingjthe roller.

carryingslidable, adjustable frames, and

taken 'online 6-6fof Fig. 1. Fig. 7 isa side elevation illustrating the sections and the tablein vertically alined position and the truckas a wholetin position ready for movement on to an elevator. Fig. 8 is a detailed? vertical transverse section taken substantially on line 8-8 of Fig. 3, and Fig. 9 fisra" vertical longitudinal section through one of the rack bar guide members.

Referring now to'thes'e figures, my improved table truck consists of an upp r.

Donson," a citizen of the United States, and a resident of" Baltimore, in the" State of'Maryland,- have made a certain new and useful 1111- f drawings which illustrate my invention, and form a part of' this specification, Figure 1 is a side elevation di'ate section A, and end sectionsB and C, which table as a whole is supported in elevated'position by means of sideuprights D GONSISTING' OF JO S EPH E.

between the sections. The said uprights D f ar'e'ri'gidly connected'to the section E of the lower frame and to the intermediate'section' A of the "upper table.

Estendingoutwardly upon each sideof the'lntermediate table section A area pair ofbolts H and ",.the latter ofiwhich is se curedto the table section and theformer of which is carried fby a bracket H in't'urnconnected'to the table section menintermediate table section, are separately pivoted rack bar guide m'embersfIandIf',

which are ,slidablyjdi'sposed. the inner ends of" rack bars J and J the outer ends of which arepivojtally connected to the table *tioned." Upon these boltsHand'l-I of the v sections BfandAC'. Thus, in'viewY of'the fact.

that there are two rack. bar guide members; f I and, I at" eachside' of the table, pivoted thereto at separate points longitudinally of the intermediate stationary table section A,

theffour. rack bars of which the two rack bars areconnected to the table section B, andf 'the two rack bars J are connectedto the" table section C, sai-dfb ars being connected to the'rnovahl etable sectionsB and C at spaced-points longitudinally thereof, the lat-- V tersections'f'are firmly and rigidly held in longitudinal}alinement with the stationary section A; the normal position of the parts, which is shown in Fig. ,1.

The stationary sectlon roller mounted frame carries rollers E,- and F i and-is I provided vwith longitudinal side guide slots F in which are guidedthe lower E of the lower 1 the movable section F carries a single roller provided'w'ith longitudinal guide slots-C in.

"noted that the sidebars K' and L are interwhich the upper end ofthe side bars L are me'diately pivoted, and are movable in their guide slots before mentioned to raise or lower the table section O to and from a position horizontally qalined with the table section A, such movement of tablesection being of course communicated to the table section B, due to the pivotally movable rack bar guide members I and I, and the rack bars guided thereby; and connected to thesaid table sections in the manner described.

. Each of the rack bar guide members I and I is also provided witha gear wheel mounted upon its pivot bolt, as best shown inFig. 9, and connecting and meshing with its rack bars so as to cause their movement m relat vely opposite directlons.- Thus whenthetable section C is lowered to the;

neath the stationary table section A to the position shown in Fig. 7, whichniovement causes relatively oppositemovem'ent of-the rack barsJ anded and also pivotal move ment of these rack bars and their guide members I and I whichresults m moving the table section B to aposition spaced above:

- the table section A and in substantially the same relation thereto as that occupied by the table section 0 below section A. It is to be understood, moreover, that the movements of sections B and C, from the position shown in- Fig. 3 to either of the positions shown in Figs. 1 and 7, are in straight lines, vertical and horizontal respectively, the change in theeffective lengths of arms J and J being necessarily taken up by slight rotation of the wheels 2'. Thus when section is moved either vertically or horizontally from the position shown in Fig. 8, its arms Jf' are forced longitudinally in a direction toward thesta'tionary section A and, through the wheels 2', the arms J of section B are similarly forced toward section A,flthe result being that sections B and level at all times. These movements are preferably accomplished by means of a handle M of suitable length, the inner end of which is connected to'the'pivoted side bars K, which bars, with the side bars L, form a lever arrangement in the nature of lazytongsfor the support of the table section C, said handle preferably having notches m cooperating with an angle bar m" on the slidable section F, to hold the parts in horizontally and vertically alined positions, as shown in Figs. 1 and 7 respectively. Thus, where bolts of dress goods and the likeare disposed upon the several sections of the table its normal horizontally alined position,as shown in Figs. 1 and 2 for transportation-from place to place on the same floor, the table truck as a whole is moved with the parts in the position shown in the tensible side railings in the C are maintained figures mentioned, and these parts needanot be disturbed for purposes of adjustment at least.

place toplace onthe samev floor,-but from one floor to another, the handle M is released 1 from the position shown in Fig. -1 and the sections of the table truck adjusted to the "position shown in Fig. 7, and in the manner described, in order that the several bolts or rolls'of dress goods disposed thereon may be .When, however, the goods "so disposed are to be transported not only from placed upon an elevator and transported to another floor of the buildin without re handling, and in order that when the table.

truck is again adjusted to its normal position asshown in Figs. land 2, the rolls or bolts ofdress goods neednot be re-handled nor inmost cases, re-checked. m

In. order that therolls or bolts of dress goodswhen piled high upon the table sections A, Band C, as 1s necessary at certain times, may be preventedjfrom slipping off during either the movement of the table truck, as a wholefroin place to place, -or when, its parts are shifted and adjusted,

these table railings indicated: at N being stationary the table sections A, B, C,these railings are hinged to swing up held in upper operative positions, as shown and down, forming" ointedsections O and O. wh1c h maybe sectionsA, B and (1 may be provlded with upright railings extending env tirely thereai'ound,certain-portions of which in dotted linesin Fig. 5,,byfmeans of ex-.-
