:P ilCIFIC-ATION forming part of Letters Ilatent` No. 286,119, dated October 2, 1883.

- Application filed August 21,1383. (No model.)

. To @ZZ 11271/0711/ t may concern.-

Be it known that I, SAMUEL DALE, a citizen of the United States, and aresident of Boonesborough, in the county of Boone and State of Iowa, have invented certain new and useful Improvements in Hod-llllevators; and l do hereby declare that the foll owing is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which lignre l is a perspective view of my iniproved bod-elevator in operative position. Fig. 2 is an end view of ilie saine, and Fig. l is a topview.

Similar letters oi reference indicate corresponding parts in all the iigures.

My invention has :relation to bod-elevators; and it consists in the improved construction and combination of parts ofthe same, as will be hereinafter more fully described and claimed.

ln tl ie accoinpau yi ng drawings, A :represents the lower story of abiiihliug which isin course oi" erection.

IB 1B indicate guide-posts, between which run the frames t) (Y which carry the hods.

D D indicate arms which are secured upon the top or iloor ofthe story A, the meeting ends ofthe said arms bei ng connected together by a cross-piece immediately above the opening through which the guide-posts B pass.

(i (Y .represent the frames which carry the` hods, the upper edge of cach frame being recessed for the reception of the hod, and having a supporting piece, C", secured upon its (frames C (Y) side, against which the handle of the hod rests. Upon either side of each frame is fastened guiding-strips E, preferably of metal, which iit upon either side ofthe guide*- posts, the frames C C' being further provided with a metal loop upon their tops, to which the hoistingropes are fastened.

Between the lower part of the arms D isj ournaled a hoisting drum orwindlass, F, having secured upon its center apulley-wheel, F', and upon either end a toothed wheel, G G', the teeth of the wheel Gbeing inclined in an opposite direction to those of the wheel G, for the purpose hereinafter specified. Upon either end of the windlass F is fastened a crank, H, by which t-he windlass may be rotated.

etween the upper part of the arms D is `iournaled an axle, I, having secured upon it, near either end, between thearms D, apnlleywheel, I, over which the hoistingropes J J pass, one end of each oi" the said ropes being secured to the windlass F, one on either side of the pulley-wheel F. A rope, l, passes around the central pulley-wheel, F', and around a drum, L, supported in suitable bearingsupon a springbar, L', the spring of the said bar serving to keep the rope K taut, thereby causing it to act to sonic extent as a brake to prevent thc windlass F from turning too rapidly.

M lvrepresent pawls, which engage with the toothed wheels (l` G".

N N represent supports pivoted at one end, which may be pushed under the frames C C when the latter are raised, in order to hold them in their elevated position.

By constructing my improved lied-elevator i u the manner described it will be seen that it can be operated from either the upper platform or from the ground. In the latter case the operator makes use of the rope K to raise and lower the hods, the pawl M servingto hold the frame C from slipping by means of the toothed wheel (1, the pawl M being raised to allow the toothed Awheel G, with which it is adapted to engage, to revolve freely beneath it while the said frame is being raisedwith a full hod upon it, the pawl M performing the same office for the frame C, the pawl M being then raised to allow the toothed wheel G to revolve freely beneath it.

Then it is desired to operate the apparatus from the upper platform, the cranks H can be utilized for that purpose. the pawls M and M being operated in the manner just described. The hoisting-ropes J J are, as will be seen by reference to the drawings, wound around the windlass F in opposite directions, so that as one frame is being raised the other is lowered.

From the foregoing description,taken in con- .nection with the accompanying drawings, the construction and manner of operating my improved hod-elevator will readily be understood without requiring further explanation..

IOO

It will be seen that my improved hed-elevator is simple in construction, and, being devoid of all complicated parts, isr not liable to break or get out of order, While it can be constructed at a small cost. By its use all climbing of ladders is avoided, thereby effecting a great saving in time. f

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States l. The combination of the guide-posts B B, sliding frames G. C', having guide-strips E, recesses O, and supporting-pieces C", supporting-'arms D D',Windlass F, having central pulley-Wheel, F', and toothed Wheels G G', secured upon it at either end, with their teeth inclined in opposite directions, pawls M M', adapted to engage with the toothed Wheels G G', axle I, having pulley-Wheels I', hoisting-ropes J J', hoisting-drum L, hung in suitableY bearings `upon a spring-bar, L', and rope K, passing around the central pulley, F', and the drum L, as and for the purpose shown andset forth.

with the toothed Wheels G G', axle I, having f pulley-Wheels I', hoisting-ropes J J', hoistingdrum L, hung in suitable bearings upon a spring-bar, L', and rope K, passing aroundthe central pulley, F', and the drum L, all` con, structed and arranged as and for the purpose` shown and described.

In testimony that I claim the foregoing as iny own I have hereunto affixed my signature in presence of tWo Witnesses.

Y SAMUEL DALE'.
