'2O ALL WHM IT MAY O'ONCERN:

Be it known that I, S. E. HEWS, of the cit)r and county of Albany, and State of New York, have invented a new and useful Iu'lproveruent in Portable Extension and Step-Ladder; and I do hereby declare the following tehe a'full, clear, and exactldeseription of the same,'suiiicient to enable one skilled 'in the art to which the invention vappertains tomake use of it, reference being h ad te the accompanying drawings which form a part of this specification, in wl1iehV i Figure 1 is a drawing showing the'stiles oftlie ladder, and thehooks and step in position when the ladder is not extended.'

Figure '2 shows the ladder, hooks, andlsteps in'position as a step-ladder.

Figure 3 is a perspective view of the balance-step.

Figure 4 is a perspectiveview of the balanced heck.

, This device consists in the make, form, shape,- and applicationof the balanced h'ook and step. Thenstep, C, shown bythe section, iig. 1, can be placed on any round of the ladder which occasion for'its use may require. Its weight brings it to the round below, on which it will firmly rest.'

' The hooks,a a, are placed on the rounds Aoi' the ladder of the second section at 5v, shownon iig/2. -The hook B is placed on the top round of the ladder of the first section. These hooks do operate together, when the ladder is extended moving .the top section of the ladder upwards, and hook to; and unheokirom any round of theladd'rfwhen and where desired` for the length Aof' the ladder: When the 'ladder is to. be converted into asten-ladder, the hooks are allowed to take the rounds, ns'shoivn at thetop of ladder, g.'2. The ladder may be extended by the use of pulley, cord, and crank, or by the hand without their u,se. The hooks are made se that the weightoi metal balances there-inv theipesiton to hook and unheok to the rounds ofithe4 up'rnoving section o the ladder at any place required. Also, with the hole through themyto worlreasily on the round of the ladder, requiring no cutting into or fasteningfthereto, thus securing the whole strength of both hooks and rounds. i y

at the foot, 5 5, of `the upper or Vsecond section, and one at thel top of ythe lower or first section, secures the strength of three rounds of eaelrsection, so that lthe splice` is Valways sec-ure, independent of any guides.' The hooks are placedin this orderrwhen the ladder`- is made of twe or more sections. i

Having'deseri'bed my invention, what-.I elairn as new, anddesre to secure by 'LettersPatent, is-
