Specification of Letters Patent.

Patented Oct. 6, 1914.

Application filed April 28, 1913. Serial No. 763,953.

ful Improvement in Conveyers, of which the following is a specification.

My invention relates to a comb shaped landing for inclined elevators and is an imthe device shown and described in my Patent, No. 963,176, issued July 5, 1910.

One of the objects of my invention is to rovide a comb shaped landing at the upper and lower ends of the inclined elevator,

whereby the passengers in ascending ordescending will be safely and comfortably received on and discharged therefrom.

Another object of the invention is to provide means which will efiect the prompt re-.

lease of wearing apparel of the passengers or any obstructions which might be drawn in at the landings.

The invention is more particularly applicable to that class of inclined elevators wherein the tread or surface upon which the passenger stands, is formed of longitudinal ridges and grooves, such as is shown in the patent referred to, and'in this typeof machine, it has occasionally been found. that foreign substances, suchv as wooden chips or fragments of sole leather become wedged at the .bottom of the grooves between the ridges of the machine, causing undue strain on the prongs of; the comb landing as-is .now

. commonly used, and which are usually made of cast iron, with the result that as the substance comes under the prong, the clearance between the pron and the bottom of the groove is not sufiicient to allow the substance to pass through .thereby causing the break-- ing thereof. A broken prong is notonly ex;- pensive and troublesome to repair, but ,it may lead to a serious accident or injury to a passenger before it is discovered, and to this end I provide a simple and efiicient means which I will now describe.

Referring to the drawings, Figure 1 shows a side view partially in section, of an upper and lower landing and a portion of an inclined elevator, with my invention applied. thereto; Fig. 2 is a plan view of Fig. 1; and Fig. 3 is an enlarged elevational view of a comb landing constructed in accordance with my lnvention.

In the following description, general reference will be made only, to the construction, etc., of the inclined elevator, as the same is clearl shown and described in the patent hereto ore referred to.

The inclined elevator comprises a series of steps 1, which are hinged together in the form of an endless belt. Thesteps are provided withrollers 2 adapted to travel on track rails 3, which are suitably secured to a supporting structure 4. Each alternate step is provided with a section of rack 5, centrally secured to its under side, and the steps alternating withthese are provided with a pair ofracks 6. The ends of the double racks 6 overlap the ends of the single racks 5, and these ends are provided with a pin connection 7 by means of which the stepsare pivotally connected to each other.

' A series of grooves 8 is formed in a tread surface 9 of the steps, in alinement with each other and parallel to the longitudinal direction of the belt, and these grooves register with prongs 10 of comb landings 11-, located at the upper and lower ends of travel 12 and 13 respectively.

The landing 11 comprises a plate '12, I

which forms the floor line at the upper and lower landings-and is held in position by means of screws 18. The floor plate is providedawith bosses 14, through which'a rod 15 extends, pivotally to support a plurality of prongs 10. The'prongs are maintained in their normal horizontal position by gravity, and their inner ends rest upon the bot tom of the floor plate at a point 15'. Extensions 16 and bosses 17 on the bottom of the floor plate maintain the prongs in proper juxtapositionv to each other.

The floor plate is positioned at the landings with respeflv to theinclined elevator, so ;that the prongs register with the grooves and extend therein a considerable distance,

whereby the foot of the passenger can he slid upon the upper surface of the prongs and the landing thus eifected w thout any sudden jar or uncomfortable sensation to the passenger, and if by accident any part of the wearing apparel of a passenger, as for example, the train of a womans dress, should extend into the grooves and be drawn in at the landing, the prongs being pivoted will effect a prompt release of the same without danger of injury to the passenger. Furthermore, if any obstructions such as wooden chips, etc., should become wedged in the groove, between the treads and should pass under the prong, it will merely raise the latter into the position shown in dotted lines, Fig. 3, and as soon as the obstruction has passed, the prong drops back into its normal position. The breaking of the prong is thus prevented, and the machine is much safer to operate than with my previous con struction.

Having thus described my invention, what I claim and desire to protect by Letters Patent of the United States is 1. An inclined elevator having longitudinal grooves formed in its tread surface, and a landing therefor provided with independently movable pivoted prongs which register with the said grooves.

2. An inclined elevator having longitudinal grooves formed in its tread surface, a comb landing therefor having a plurality of independently movable pivoted prongs which register with the said grooves.

3. In an inclined elevator, the combination with a series of treads operatively connected together in the form of an endless belt, having longitudinal grooves formed in its tread surface, a landing'therefor having a plurality of independently movable pivoted prongs which register with the said grooves.

4. In combination, an inclined elevator having longitudinal grooves formed in its tread surface, a comb landing therefor, comprising a floor plate, a plurality of pivoted prongs which register with the said grooves, and means associated with the floor plate pivotally to support the said prongs.

5. An inclined elevator having longitudinal grooves formed in its tread surface, and a landing therefor comprising 'a floor plate, prongs pivotally supported thereon and positioned to register with and extend into the said grooves. p

6. An inclined elevator having longitudinal grooves formed in its tread surface, and a floor plate therefor having pivoted prongs which register with the said grooves, the said prongs each having an abutment thereprongs pivotally supported thereby and eX- tending laterally therefrom.

9. A comb landing for inclined elevators, comprising a floor late having a plurality of pivoted prongs, t e said prongs each having an abutment thereon to engage the bottom of the floor plate, to maintain the prongs in a lateral position with the: floor plate against the action of gravity.

10. A comb landing for inclined elevators, comprising a floor plate, a. plurality of pivoted prongs extending laterally therefrom, and a rod associated with thefi'oor plate pivotally to support the said prongs. I

11. A comb landing for inclined elevators, comprising a floor plate having a plurality of pivoted prongs, the said prongs each having an abutment thereon to engage thebottom of the floor plate, and a rod associated with the floor plate pivotally to support the said prongs.

12. A comb landing for inclined'elevators, comprising a floor plate, a plurality of pivoted prongs extending laterally therefrom, a rod associated with the floor plate for pivotally supporting the said prongsyand bosses integral with the floor plate for keeping the prongs in proper juxtapositionto each'other.

13. A comb landing for inclined'elevators, comprising a floor plate having extensions thereon which form bosses to-receivea rod, prongs positioned between the bosses and pivotally supported on thesaidrods, the said prongs each having anv abutment there'- on engaging the bottom of the floor plate, to maintain the prongs in a lateral-position with the floor plate against the-action. of gravity.

In testimony whereof, I' have signed my name to this specification in the presence of two subscribing witnesses.
